2. Introduction The SP1200 is a single-channel version of our popular SP2400 dual-channel microprocessor-based music controller. Having a single 200 watt power amplifier, it's designed for use in a variety of installations requiring high performance, flexible features, and ease of use. Examples of such installations are retail stores, restaurants, bars, and theme venues. The SP1200 provides one output that can be used for single-zone coverage.
Front Panel Features Rear Panel Features INPUTS select buttons are used to choose the program source for the zone. Only one source may be selected at a time. These are non-priority inputs. However, Input 4 can become a Program Priority Input by setting the AMP ADDRESS switch #7 UP. In this mode, when a signal is present on Input 4, it automatically overrides whatever input source is selected for that zone. This is useful for jukeboxes or alternative paging configurations.
The PAGING MIC VOX variable control adjusts the ducking threshold for the paging mic. Rotate the control clockwise to reduce the threshold. Rotate the control counterclockwise to increase the threshold. MIC/LINE INPUT is provided to connect a local microphone. This is a 3-pin Phoenix-type connector where pin 1 is ground, pin 2 is signal high (+), and pin 3 is signal low (–). AMBIENT MIC is a 3-pin Phoenix-type connector used to connect the optional MT-3100 ambient microphone.

Note: This application provides independent source selection for each zone, or common input source selection for both zones (room combining). Both DX8 Selection Remote Controls are used to select Presets 1 and 2. For example, Preset 1 might route the CD Player and the Zone A microphone to Zone A, and the Cassette Player and the Zone B microphone to Zone B, to be used when the divider is in place between the two zones.
Applications A: Typical Mono Application This diagram depicts a typical setup, using the SP1200 in a mono application. A Digital Satellite Service (DSS) is connected to Input 1, which also serves as the music-on-hold for the telephone system. A CD player and cassette deck are connected to Inputs 2 and 3 for general purpose music playback. A jukebox is connected to Input 4, which is configured for priority playback via AMP ADDRESS switch #7.
CAUTION: When using multiple SP1200s that use the expansion bus, these switch settings must be unique to each unit or you can damage your SP1200(s). Never assign more than one program source to the same channel on the Expansion Bus. Zone A B C D E F G So SA urc T e CD Ca s Tu set n te Ju er ke bo x If there is a requirement for music-on-hold, use Input 1 for the continuous music source (i.e., satellite feed, prerecorded background music, multidisc CD player).
Connecting the Expansion Bus These are 25-pin D-Sub connectors (DB25F). The two connectors are wired in parallel, so it doesn’t matter which one you use as an input or output. The signals on the EXPANSION IN/OUT are balanced so they can be transmitted down long lines. The limiting factor is the capacitance of the cable, which causes the higher frequencies to rolloff as the capacitance increases (see chart below).
Connecting the RS485 Serial Port This is a 3-pin Phoenix-type connector that follows standard RS485 protocol. Select either a data-grade shielded twisted pair cable or a standard 3-conductor microphone cable for this connection. The RS485 port is wired as follows: Pin 1 = A (non-inverting I/O) Pin 2 = G (Ground) Pin 3 = B (inverting I/O) The SPLinker Sound Palette Control PC application uses the RS485 serial port to connect between a computer and the SP1200.
On the Amplifier Board EQ Bypass Jumper J6, located on each Filter Board, allows you to bypass the 3-band EQ for the four Program Inputs. J1 Jumper pins 1 and 2 for 8-ohm operation Jumper pins 2 and 3 for 70V or 100V operation Jumper pins 1 and 2 to bypass the EQ. Jumper pins 2 and 3 to engage the EQ (default). J2 Jumper pins 1 and 2 for 100V or 8Ω/250W operation Jumper pins 2 and 3 for 70V or 8Ω/150W operation Note: The top Input Board must be removed in order to access Jumper J6 on the Filter Board.
AC Power Considerations Each SP1200 draws an average of 3 amps of AC line current (@ 120VAC) when fully loaded and playing music with a relatively high crest factor. Voltage Conversion The SP1200 can be configured to operate at 115V AC or 230V AC. See Appendix C for instructions on how to change the operating voltage configuration. Thermal Considerations IMPORTANT: The SP1200 is convection cooled rather than fan cooled.
4. Operation SP1200 Quick Start This isn’t a substitute for reading the entire instruction manual, which is the only way to fully understand how the SP1200 works. However, the Quick Start provides a quick overview so you can get the SP1200 set up and working right away. Make sure the power switch is off while setting up and making connections to the SP1200. External Switch Settings • Bus Assign switches are used to assign a program input source to the balanced expansion bus.
PAGING MIC CONTROL The PAGING MIC CONTROL connector is provided to connect a manual paging switch. Connect a normally-open switch between GND and ZONE A (to page in Zone A only), or GND and ALL CALL (to page over the entire system--if using multiple units). The voice-activated (VOX) control for the Paging Mic still operates in Zone A when the switch is off.
Using Inputs 1-4 Bus Assign Connect the program sources to Inputs 1-4. These could include a CD player, tape deck, tuner, satellite feed, TV audio, jukebox, or an audio feed from a live band. All four program inputs use unbalanced RCA connectors and accept stereo linelevel signals. Note: The Input Select buttons are labeled 1 through 4 on the front panel. The spaces below the buttons are sized to accept 1/4" labels from the Brother P-Touch Electronic Labeling System.
Using the Paging Mic The paging mic is used to make announcements over the system. If the paging mic is a condenser mic or other type of mic that requires phantom power, move the PHANTOM switches to the down position. Otherwise, leave them switched up. The paging mic can be voice-activated and is routed to all channels or zones. However, you have the option of activating it manually with an external switch.
Ambient Mic Calibration and Placement 1. Connect the MT-3100 (or other microphone) to the AMBIENT MIC connector on the rear panel. Make sure the ambient mic switch is on (AMP ADDRESS switch #8 up). Locate the ambient mic in an appropriate position to pick up the ambient noise in the room. It can be mounted on the ceiling or on a wall. Avoid placing the ambient mic close to the speaker over which the announcement is being made.
Using the EQ Each local MIC/LINE INPUT has a 2-band equalizer for adjusting the lows or highs on the microphone signal. When the controls are set to “U” (unity), the EQ has no effect on the signal. Using the PRE OUT/AMP IN Connections The PRE OUT and AMP IN connectors are provided to give you more flexibility in your system design. The SP1200 is shipped with U-shaped jumpers installed between the PRE OUT and AMP IN jacks.
ADDRESS switch #6 in the Master position (up), and the other unit in the Slave position (down). In this way, you can have one Remote control operate both amplifiers that are assigned to the same zone. Note: The microprocessor polls the AMP ADDRESS switch when it initializes at power-up. If a change is made to the AMP ADDRESS switch, turn the SP1200 off for five seconds, then turn it back on again for the new settings to take effect.

Appendix B: Button Modes SP1200 Button Modes Press 1 on Power Up: AGC Reset • Press and hold the Input 1 button while powering up the SP1200. • Release the Input 1 button and the Input 1 LED blinks. This resets the AGC for all four inputs to the default setting (–5 dBu). • Press the Input 1 button again and the OFF LED lights. This indicates that the AGC circuit is turned off. • Press the Input 1 button again and the OFF LED turns off. This indicates that the AGC circuit is turned on.
Appendix C: Voltage Conversion CAUTION: These servicing instructions are for use by qualified personnel only. To avoid electric shock, do not perform any servicing other than that contained in the Operating Instructions unless you are qualified to do so. Refer all servicing to qualified service personnel. Make sure the power is off and the power cord disconnected before removing the top cover to gain access to the inside of the SP1200.
