Introduction This manual contains information on how to mount, install, and configure the Extron® SSP 7.1 surround sound processor. Unless otherwise specified, references in this manual to the SSP 7.1, “sound processor,” or “surround sound processor” all refer to the SSP 7.1 unit. About the SSP 7.1 The SSP 7.1 is a 7.1 channel surround sound processor with four digital inputs and one analog input. A variety of selectable listening modes can be changed to match the source format.
SSP 7.1 Features Advanced control and configuration — The SSP 7.1 Setup and Control Software provides additional configuration options beyond those available through front panel control. Emulate and Live modes for configuration — The control program can be used in Emulate mode to create an SSP 7.1 configuration. The modifications can be saved and applied to the unit when a connection is established. In Live mode, the changes are made directly to the unit.
Test signals for setup and calibration — The SSP 7.1 generates test signals, including band-limited Dolby noise and full-bandwidth pink noise, to facilitate calibration of sound pressure levels from all speakers, and to fine-tune the interaction of a speaker with the acoustical environment. The SSP 7.1 also offers the option to use an external source for test signals, which can then be directed to any speaker, or all speakers in sequence.
Features The next two sub-sections describe the features and operation of the SSP 7.1. zz Rear Panel Features zz Front Panel Features and Operation Rear Panel Features INPUTS 100-240V .5A 50/60Hz DIGITAL 3 2 1 a Figure 1.

NOTES: • The length of the exposed wires in the stripping process is critical. The ideal length is 3/16 inches (5 mm). Any longer and the exposed wires may touch, causing a short circuit between them. Any shorter and the wires can be easily pulled out even if tightly fastened by the captive screws. • Do not tin the wires. Tinned wire does not hold its shape and can become loose over time.

Mode Override Selection g Mode Override selector — The SSP 7.1 has a wide range of listening modes, although not all listening modes are compatible with every source format. The speaker configuration of the system may further limit which listening mode is available for a source format. Other factors, such as the room layout and listener preferences, may also influence the listening mode selection. The SSP 7.1 has default listening modes associated with each source format.
zz To All (TO ALL) — Distributes a mono or 2-channel source to all applicable channels. zz Mono sources are sent to all available output channels, including center. zz 2-channel sources are sent to all stereo pairs only. zz Multichannel sources are downmixed and output to Mono to All or Stereo to All, as defined by the user. zz Digital or analog stereo sources may be output to Mono to All or Stereo to All, as defined by the user.
Input Selection 1 2 Figure 5. h INPUTS 3 4 5 CLIP SSP 7.1 Input Selection Switches Input selections — Push one of the buttons to select between five possible audio inputs. The LED next to the currently active input lights. In conjunction with the Mode Override button, the input buttons are used to mute all outputs (see page 10). The input buttons are also used to enable or disable front panel security lockout (executive mode). For more information, see page 12.
Mute Output When the mute state is enabled, all channels are muted simultaneously. To toggle between mute and unmute: 1. Press and hold the active input button (the button next to the LED that is lit). 2. While still holding the active input button, press the Mode Override button. When the mute state is enabled, the individual LEDs of the Volume Adjustment LED bar light in sequence from the top down. This scrolling down pattern repeats while the mute state persists.
Volume Adjustment i Volume adjust knob and LED bar or Analog input gain level control and LED bar — Use the rotary encoder to adjust the output volume from 0 (-100 dB) to 100 (0 dB). The default setting is 50 (-50 dB). VOLUME The degree to which the volume is incremented or decremented for each step the encoder is turned, depends on the current volume setting (see the last column in the table below).
The LED bar lights from the bottom up to indicate the current gain level. No LEDs lit indicates no gain (0 dB, or unity gain); all the LEDs lit indicates maximum gain (24 dB). Each solidly lit LED represents 3 dB.
Setup This section provides background information about arranging speakers in a room and about some of the settings that can be adjusted by the SSP 7.1 Setup and Control Software. Extron strongly recommends that the control software is used to make any configuration changes to the SSP 7.1. (See “Setup and Control Software” on page 22).

R C L RECORDING Progressive DVD-RW/-R Cinema Precision SW RS LS RB LB Figure 9. CB Subwoofer Placement NOTES: • To produce a good bass response from the subwoofer, it should be located at the front of the room, somewhere between either corner and a point about one third of the way along the front wall. • The output channel used for the Left Back speaker (in 7.1 configurations) is also used for the Center Back speaker (in 6.1 configurations).
Large — Bass management is off for that speaker. The full range of audio frequencies from the audio source is fed through the output of each individual channel. This may be set in the absence of a subwoofer. By default, front speakers are set to large. When there is no subwoofer, all speakers set to Large (except the center channel) receive the summed audio from the filtered low frequency signals of speakers set to Small. None — This mode prevents any signal from being sent to that output channel.
Speaker Delay Settings There are two different signal delays that compensate for different needs. Compensation delay — In a room where speakers are not equidistant from the listener, sound from the closest speaker reaches the listener before sound from the farthest speaker. This feature allows the user to enter the speaker distance value for each speaker output channel. The application calculates the delay values for the closest speakers, up to 100.
Listening Mode Settings The SSP 7.1 provides a range of settings that refine the sound distribution for each listening mode, depending on the decoding mode that has been selected. Dolby Pro Logic II or IIx Music Dimension control — This feature alters the ratio of L+R to L-R for two-channel input signals, which adjusts the sound field towards the front or towards the back. The available settings are Front, Neutral, or Back. The default setting is Neutral.
Dynamic Range Compression Control This control is available only with Dolby Digital and DTS source formats that have a Dynamic Range Compression flag. This control adjusts the gain applied to Dolby Digital or DTS listening modes to compress the signal outputs during the decoding process. The three possible settings are None, Minimum, and Maximum. The default setting is None. Off — The signal is uncompressed and is played with the full original dynamic range. Minimum — The audio is partially compressed.
Tone Controls These controls regulate the bass and treble settings for the system. To adjust the bass or treble tone controls, see Tone Controls on page 27. Bass — The bass control regulates the amount by which low frequency signals are boosted or cut (see figure below). It is applied to outputs for all speakers, including the subwoofer. Figure 10.
Volume Output This control sets the volume of the audio output through all channels, globally, to either Variable (the default value) or Fixed. Variable — When the Volume output is set to Variable, the volume can be attenuated using the front panel knob, the SSP 7.1 Setup and Control Software, or SIS commands. Fixed — The Fixed option sets the volume to the current attenuation level.
Setup and Control Software The SSP 7.1 Setup and Control Software provides an intuitive, easy to operate, graphical user interface that allows the user to configure the audio system quickly and efficiently. It provides more options than the front panel. As selections are made, only the options that are available for the current configuration are displayed by the software. Extron strongly recommends using the SSP 7.1 Setup and Control Software for all configuration.
If the new software detects an old version of the Firmware, a pop-up window informs the user that the firmware should be updated and also prompts the user to save the existing configuration for reloading onto the SSP 7.1 when the new firmware has been installed. When the firmware has been updated, open the SSP 7.1 software in Emulate mode (see below) and open the saved configuration.
When the SSP 7.1 Control and Setup software is opened directly to Live mode, the current configuration in the device is read from the SSP 7.1 unit, automatically overwriting the settings in the software. When the program is closed, you are prompted to save any changes that have been made during that session. Figure 13. Save changed configuration Box Running the SSP 7.1 Setup and Control Software Connect to device? Dialog Box The computer must be connected to the SSP 7.
3. Click the Connect button (or Cancel to exit the program). If you select Emulate, click on the Work Offline button (or Cancel to exit the program). Figure 15. Connect to device? Dialog Box — Emulate Mode NOTE: When Emulate/Work Offline is selected, the Connect button is replaced by a Work Offline button.
Main Tab The program opens with the Main tab selected. Two other tabs are available: Speaker Setup (page 30) and Listening Mode Setup (page 45). It is advisable to configure each tab in the sequence they appear at the top of the screen. Full instructions on how to configure each screen are available in the help file, which can be accessed under the Help menu option or by pressing F1 from within the program. Figure 16. Main Tab The Main tab offers the options that are available on the SSP 7.
Tone controls — Bass control adjusts the amount of low-frequency boost or cut applied to the audio outputs for all speakers, including the subwoofer. Treble control adjusts the amount of high-frequency boost or cut applied to the audio outputs for all speakers, except the subwoofer. Both controls are adjustable between -10 dB and +10 dB, and the current value is shown in the text box. Adjust the value in any of these ways. zz Grab and drag the slider bar to adjust tone in 1 dB increments.
Input and Output information bar — The Input and Output information bar, on the right side of the screen, is visible in all tabs and provides information about: zz zz The current input zz Selected input channel zz Source format zz Sampling frequency zz Encoded channels The current output zz Speaker configuration zz Listening mode zz Mode override selection zz Master volume zz Mute NOTE: While the Master Volume value and Mute status can be adjusted using the slider bar and button in this
Output status — A text box indicates the speaker configuration, the current listening mode, and the mode override status. Underneath, a box shows the current speaker configuration. Speakers that are available are highlighted in blue and speakers that are not available are not shown. Speakers that are set to large (see Speaker Configuration on the next page) are represented by large icons and speakers that are set to small are represented by small icons.
Speaker Setup Tab After completing the Main tab, the next tab is Speaker Setup, which is the first tab to allow system configuration that is not available from the front panel. The Speaker Setup tab provides access to four second-level tabs (Speaker Configuration, Speaker Delay, Testing & Output Trim, and Speaker Equalization). Speaker Configuration Tab Figure 18. Speaker Configuration Tab Speaker size Speaker size determines whether or not bass management applies to that speaker.
zz Left and right front speakers and left and right surround speakers are set in pairs. zz The center speaker is set as an individual speaker. zz Back speaker(s) can be set as a single speaker or as a pair of speakers, depending on the system configuration. zz The subwoofer can be set to Present or None. Small — Bass management is on (see page 15). Large — Bass management is off (see page 16).
Speaker Delay Tab After completing the Speaker Configuration tab, configure the Speaker Delay tab. Figure 20. Speaker Delay Tab These controls introduce a signal delay for each speaker that has not had its size value set to None. The two main reasons to adjust the signal delay are: zz To compensate for unequal distances between the speakers and the listener, which causes sound from different speakers to reach the listener at different times.
Extron recommends that the SSP 7.1 Setup and Control Software is used to set speaker delays, using either of the following methods. Two person setup NOTE: Setting up speaker delays is easier with two people. If only one person is available, the position of the ears of the listener must be marked precisely. A pile of boxes could be used to ensure that the distances are consistently measured to the correct height. Do not try to guess ear positions, as this introduces measurement errors. 1.
4. Click the Apply button to save the changes. The new values (previously in orange) are shown in blue as the current values and there are no values displayed in orange. To retain the original values, click Cancel instead of Apply. Figure 22. Calculated Delay — Values Applied NOTE: Users who wish to calculate the delay time for themselves should follow the full procedure shown on page 94 in “Setting Speaker Delay Settings using SIS Commands.” Setup with a Real Time Analyzer (RTA) calibration tool 1.
Lip Sync Offset Lip sync offset compensates for a lack of coordination between the audio and the accompanying video signal. This frequently occurs if the video signal has undergone complex manipulation that can delay it several milliseconds relative to the audio signal. Since some sources may require more manipulation than others, the lip sync offset is set for each source individually to synchronize the audio for that source with the corresponding video signal.
Testing & Output Trim Tab After the Speaker Delay tab, configure the Testing & Output Trim tab. Figure 23. Testing & Output Trim Tab Several factors can affect the sound level reaching the listener from different speakers. These factors include the distance from the speaker to the listener, slight variations between the output channels of a single amplifier, and variations between the individual speakers.
Set the external source to Mono to All using one of these methods. Listening Mode Preferences Tab 1. Select the listening mode Preferences tab (see page 45). 2. Select the input channel that is providing the test signal source (1-5). 3. For whatever source format the test signal is using, select Mono to All. 4. Return to the Testing & Output Trim tab and click on Active Input. Override Preferences Tab 1. Select the Override Preferences tab (see page 48) and select the input source. 2.
Speaker test sequence 5.1 Setup To run an automatic test sequence 6.1 Setup 7.1 Setup Left Front channel 1. Select the Auto button. This sends a two second test signal to each output channel in the sequence shown in the diagram at right. All other speakers are muted. The test sequence cycles through each speaker multiple times until the test signal is switched off. 2 Sec Center channel 2 Sec Right Front channel 2 Sec Right Surround channel 2.
Output Trim The Output Trim sliders control the audio signal level for each individual channel output. Only channels that are enabled in the current speaker configuration are available; the others are displayed but cannot be adjusted. Output trim is adjustable from -24 dB to +12 dB. The current value for each output channel is shown in the text box. Figure 24. Output Trim NOTE: The maximum output volume is tied to the output trim.
In the example below, the SPL readings for five channels are given in column 2. Channel 4 has the lowest reading and is used as the zero reference point. The difference between each speaker and the zero reference is calculated in column 3. This is the adjustment that must be made to the output trim for that channel. Channel SPL Reading Output Trim Adjustment (dB) 1 75 -1 2 76 -2 3 79 -5 4 74 0 (zero reference channel) 5 77 -3 5.
Speaker Equalization Tab After the Testing & Output Trim tab, configure the Speaker Equalization tab. Figure 25. Speaker Equalization Tab The Speaker Equalization tab provides nine parametric EQs for each output channel. The default frequency values correspond to a nine-band graphic equalizer, which provides a starting point for refining the output signal from each speaker channel. All the properties of the SSP 7.1 parametric EQs can be defined by the user.
When an EQ has been selected, it can be adjusted in the graphic box or the text boxes at the bottom of the screen. When the bypass is activated for an EQ, the values are saved for future use but do not act on the signal path. When the bypass is deactivated, changes made to that EQ contribute to the composite graph that is displayed. The graph shows how the activated EQs combine to affect the signal path in the current setup. Right click the EQ number to bring up a context sensitive menu (see figure 27).
In the graph below, EQs 1, 2, 3, and 4 have been adjusted. The effects of adjusting EQs 2, 3, and 4 can be seen by the deviation from the horizontal line. The effect of adjusting EQ 1 is not seen because the bypass button for that EQ is still activated and adjustments to EQ 1 are not used to process the audio signal. The numbers of the EQs contributing to the graph (2, 3, and 4, but not 1) are shown in white against a blue background at the top of the graph. Figure 29.
Test Signals Use the Test Signals section of the screen to select Pink Noise or the Active Input signal as the sound source. Use the sequence arrows to apply the test signal to the appropriate output channel. Input and Output information bar The Input and Output information bar is available from all GUI tabs and is described in detail on pages 28 and 29. SSP 7.
Listening Mode Setup Tab After completing the Speaker Setup tab, the final tab is Listening Mode Setup. This tab provides access to three second-level tabs (Preferences, Override Preferences, and Dolby, DTS, and Mono Settings). For each combination of source format and speaker configuration, the SSP 7.1 has a default listening mode. However, this cannot take into account the characteristics of the room or the personal preferences of the listener.
Listening mode selection Use the drop-down menus to select the preferred listening mode to be associated with each source format. A full list of all options can be found in “Source Formats and Listening Modes with Different Speaker Setups” on page 75. The available selections are dynamically populated so that they represent only the values that are available for the current speaker configuration. When input 5 is selected, the only Source Format available is Analog (see figure 32 below).
The Selected Override text matches the current state of the front panel Mode Override LEDs. No Mode Override selected MODE OVERRIDE DOWNMIX PL II/IIx DTS NEO:6 TO ALL Downmix selected MODE OVERRIDE DOWNMIX PL II/IIx DTS NEO:6 TO ALL Dolby PL II/IIx selected MODE OVERRIDE DOWNMIX PL II/IIx DTS NEO:6 TO ALL DTS Neo:6 selected MODE OVERRIDE DOWNMIX PL II/IIx DTS NEO:6 TO ALL To All selected MODE OVERRIDE DOWNMIX PL II/IIx DTS NEO:6 TO ALL Figure 35.
Override Preferences Tab Listening mode override After selecting the listening mode, click on the Override Preferences tab to adjust the mode override options. These preferences are applied when the front panel override option is engaged and allow further refinement of the front panel override. The available options for each mode override group are listed under the appropriate drop-down menu. Figure 36.
Dolby, DTS and Mono Settings Tab After configuring Override Preferences, click the Dolby, DTS and Mono Settings tab. Figure 37. Dolby, DTS and Mono Settings Tab This tab allows advanced adjustments to the settings for Dolby ProLogic II/IIx Music, DTS Neo:6, and how mono signals are received and output by the SSP 7.1. Dolby Pro Logic II/IIx Music Settings The Dolby Pro Logic II/IIx Music listening mode is used for listening to any stereo music recordings.
DTS Neo:6 settings Center Image Settings These controls set the center image for DTS Neo:6 Cinema and DTS Neo:6 Music listening modes. More information about this listening mode is found on page 69. The sliding bars adjust the center image control settings: zz DTS Neo:6 Cinema: 0 - 10 (the default is 10) zz DTS Neo:6 Music: 0 - 10 (the default is 3) Setting the control to 0 creates the effect of spreading out the audio signal across the front speakers.
Drop-down Menus The menu bar at the top of the window provides additional tools and options. The four top-level headings are File, Device, Options, and Help (see figure at right). File The File menu options allow you to save changes made to the configuration of the SSP 7.1, whether you are running the software in Live or Emulate mode. The current configuration can be saved as an *.esp file, which can be opened, further modified, saved, or saved by a different name. The File menu has five options.

Reference Material This section provides information about Source Formats and Listening Mode Options and Usage. Source Formats Surround Channel Information Surround channel information is written in the following format: A/B.C (For example 3/2.1) A represents the number of front channels (maximum 3: front right, front left, and center). If A is 1, the source format has a mono encoded signal for playback through the center channel.
Encoded Channels Minimum Required Output Speaker Configuration 1/0.0 or 2/0.0 2.0 1/0.1 or 2/0.1 2.1 2/1.0 5.0 2/1.1 5.1 2/2.0 5.0 2/2.1 5.1 2/3.0 6.0 2/3.1 6.1 3/0.0 3.0 3/0.1 3.1 3/1.0 5.0 3/1.1 5.1 3/2.0 5.0 3/2.1 5.1 3/3.0 6.0 3/3.1 6.1 NOTES: • The minimum allowable configuration of the SSP 7.1 is 2.0 because the left and right front speakers are always on. In the absence of a center channel, 1/0.0 and 1/0.1 encoded channels are output equally to both front channels.
Dolby Digital Source Formats ( D) Inputs 1- 4 only Dolby Digital 5.1 (3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1, or 1/0) Dolby Digital is a flexible, discrete, digital technology for carrying audio. Dolby Digital is a 5.1-channel surround sound format and is the standard for DVD video. Dolby Digital features up to five discrete channels (front center, front left, front right, surround left, and surround right), which gives it the “5” designation.
DTS Source Formats (DTS) Inputs 1- 4 only DTS 2-Channel (2/0) DTS 2-Channel is a specific DTS encoded stereo format. Material encoded in this source format is typically found in DTS-HD Blue Ray DVDs and is primarily intended for playback by the left and right front speakers. When this source format is present, both the DTS and the 2-CH LEDs light. DTS Digital Surround (3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1, or 1/0) DTS Digital Surround is a 5.
PCM Digital Source Format (PCM) Inputs 1-4 only Two channel, uncompressed, digital signals are processed through any of the four digital inputs. The sampling frequency of the digital signal is displayed by the SSP 7.1 Setup and Control Software. When the SSP 7.1 detects this source format, both the PCM and 2 CH LEDs are lit. 2-Channel Source Format (2CH) Analog Input 5 only Any balanced or unbalanced stereo signal (or two balanced or unbalanced mono sources) is accepted.
Listening Mode Options and Usage Listening Mode Options Stereo This mode plays a stereo source in its pure, unprocessed form. It is the default factory setting for any analog signal and any PCM or Dolby Digital 2/0 source coming through the digital inputs. It can be used to downmix a multichannel source format into a mixed stereo output signal. Mono This mode plays mono source material or stereo that has been mixed to a mono form.
DTS This mode is used with DTS Digital Surround encoded source formats. It also produces up to 5.1 discrete channels (center, left and right front, left and right surround, and a low frequency effects channel). This is the default mode for DTS-ES Matrix 6.1 source formats when the system is set up for 3.0 to 5.1. It can be used with this source format to play the audio without the matrix‑encoded back channel information.
Dolby Pro Logic II/IIx Movie or Music Dolby Pro Logic II builds on Dolby Pro Logic by breaking the mono surround channel into a pair of stereo surround channels for playback in a 5.1 surround sound setup. This is achieved by a matrix surround decoder. Dolby Pro Logic II works only with two-channel source formats that are used in a 5.1 configuration. It is available as Dolby Pro Logic II Movie and Dolby Pro Logic II Music.
DTS + Dolby Pro Logic IIx Movie or Music This mode uses Dolby Pro Logic IIx matrix mixing effects to create up to two additional surround back channel effects from the original 5.1 information of a DTS Digital Surround source format. Both the Movie and Music modes produce up to seven full bandwidth matrixed channels for right and left back surround. NOTE: This listening mode is available only when the SSP 7.1 is set up for 6.0 to 7.1 channel outputs and a DTS Digital Surround source format is present.

5. Calculate the delay time (in ms) for each speaker, where: Delay Time = Delay Distance / Vs NOTE: The constant Vs (the speed of sound) is 0.343 m/ms or 1.12533 ft/ms. 6. For SIS commands, the delay time must be converted to units of 0.1 ms: SIS Delay time = Delay Time (per ms) x 10 7. Compile the information into a table (if possible, use a spreadsheet program to carry out the calculations automatically).
Setting up Test Sources with SIS Commands Extron recommends that the SSP 7.1 Setup and Control Software is used to calibrate the system with the test signals, as described on page 36. If this is not possible, the system can be calibrated using SIS commands. Using Pink Noise or Dolby Noise test signals 1. Send the SIS command that turns on the test source as Pink Noise (EX2TSTA}) or Dolby Noise (EX1TSTA}). 2. Send the SIS command that mutes all output channels (1Z). 3.
Mounting This section outlines the various mounting options available for the SSP 7.1. Tabletop Placement Rack Mounting Under-desk Mounting Tabletop Placement Attach the four provided rubber feet to the bottom of the unit and place it in any convenient location. Rack Mounting UL Guidelines for Rack Mounting The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack: 1.
Rack Mounting Procedure The unit can be mounted on any of these optional rack systems, including: zz RSU 129: 9.5 inches deep, 1U rack shelf kit (part number 60-190-01) zz RSU 126: 6 inches deep, 1U rack shelf kit (part number 60-190-10) To mount the scaler on a rack shelf, follow the instructions provided with the shelf accessories.
Glossary Bass Management — Low frequency sounds are usually better handled by the subwoofer speaker. Bass Management organizes the low frequency component of designated input signals, along with the Low Frequency Effects (LFE) information encoded in the source format and passes that information to a subwoofer (if available). (Also see Crossover Frequency, Low Frequency Effects, and Speaker Size.
Executive Mode — see Front Panel Security Lockout. External Source (Test Signal) — An external calibration source, is usually used to test specific decoding mode outputs. When the External Source option is chosen, the speakers that receive the test signal can be specified. Front Panel Security Lockout — When Front Panel Security Lockout is enabled, the front panel is locked and the user is unable to make any changes from the front panel (except disabling the lockout).
Speaker Size — Speakers can be set to Large, Small, or None. Speakers set to Large play the full range of sound intended for that output channel. Speakers set to Small play only the frequencies that are above the crossover frequency. The low frequency portion of the signal from that channel is incorporated into bass management and directed to the subwoofer (if present) and speakers that have been set to large.
