GUIDE TO INSTALLATION AND OPERATION 3.3 Remote control using iControl The operation of the UAP-1783 may be controlled using Miranda’s iControl system. • • This manual describes the control panels associated with the UAP-1783 and their use. Please consult the iControl User’s Guide for information about setting up and operating iControl. In iControl Navigator or iControl Websites, double-click on the UAP-1783 icon to open the control panel.
GUIDE TO INSTALLATION AND OPERATION Status Icons At the top, to the left of the Miranda logo, are ten status icons that report various aspects of the card’s operation.
GUIDE TO INSTALLATION AND OPERATION 3.3.1 Audio Processing 3.3.1.1 Audio Processing - CH 1-4 to CH 13-16 tabs The channels 1 to 4 are the analog inputs, channels 5 to 8 are the digital inputs. When a video card is present, 8 extracted audio channels are available as Channel 9 to Channel 16, see ABUS Input Section (page 24).
GUIDE TO INSTALLATION AND OPERATION Config sub-tab: this tab sets the card’s behaviour in the event of a loss or absence of audio signal. • A signal absence is declared when the signal level is lower than the signal threshold during the selected period. The threshold can be set through the pull-down box to –72, 66, -60, -54 or -48 dBFS, the default value is –60 dBFS.
GUIDE TO INSTALLATION AND OPERATION 3.3.2 Dynamic Processing This process is part of the input processor, refer to the block diagram on page 2. 3.3.2.1 CH 1 to CH 8 tabs: Each of these tabs controls the dynamic processing for one channel. The available functions are Limiter, Compressor, and Downward Expander. A Gain trim allows compensation of the loudness attenuation that follows compression.
GUIDE TO INSTALLATION AND OPERATION 3.3.2.2 CH 9 to CH 16 tabs: The functions are same as above but for the channels 9 to 16.
GUIDE TO INSTALLATION AND OPERATION 3.3.3 Audio Output 3.3.3.1 Audio Output - CH 1-2 to CH 7-8 tabs: Each of these tabs controls the output processing for two output channels – source selectors, level controls and mixers for each output. A coloured box indicates the audio type for each output of the card. • Detected audio types can be PCM, AC3 (Dolby Digital), Dolby E or N-PCM (other non-PCM). The Operation Mode pulldown establishes the configuration of the controls for an output channel.
GUIDE TO INSTALLATION AND OPERATION Mix (see CH 3 in the figure on the right) Two sources are selected using the Source A and Source B ABUS Select and Channel pulldowns. The two sources are mixed, with the level of each source adjusted using its slider or data entry box. • • The ABUS select options are: oV select one of the 16 channels from the video card. o A1 select one of the 16 channels from an audio card.
GUIDE TO INSTALLATION AND OPERATION 3.3.3.2 Audio Output - Config tab: The Output 0 dBFS pulldown box sets the analog output conversion ratio: • the default value for 0 dBFS will be +24 dBu, and it can be adjusted down to 0 dBu. 3.3.4 UP/DOWN MIX 3.3.4.1 UP/DOWN MIX – Config tab With the UP/DOWN MIX option enabled (see section 3.3.
GUIDE TO INSTALLATION AND OPERATION 3.3.4.2 UP/DOWN-MIX – UP-MIX tab: This feature is used to create, from a stereo source, a multi-channel compatible audio signal with up to six channels: Left, Right, Center, Left Surround, Right Surround and the Low Frequency Effect. The selection of the stereo source is done with the two pull down boxes Left Source and Right Source. The Type pull down box offers three different standard mixes and a custom position.
GUIDE TO INSTALLATION AND OPERATION is present, down-mix levels default to those currently set by the user in the L/R, Center, Surround and LFE pulldowns. • Manual the user sets the down-mix levels via the L/R, Center, Surround and LFE pull-down boxes: the default values are: o L/R 0 dB o Center -3 dB o Surround -3 dB o LFE cut Select “Level Normalization” ON to ensure a constant level of the down-mix output into the audio channels 15 and 16.
GUIDE TO INSTALLATION AND OPERATION 3.3.5 Channel Status 3.3.5.1 Channel Status - Status tab: This tab displays the most relevant parameters coded within the incoming AES channels: USE Displays PRO or Consumer PCM Coding of incoming data: Linear or Non-Linear. Emphasis Coding of the emphasis applied on the signal. Freq. Mode Indicates if the source is locked to a local reference signal. Samp. Freq. Value of the sampling frequency. Chan. Mode Describes the way the two channels are used.
GUIDE TO INSTALLATION AND OPERATION 3.3.6 Audio Type This Window indicates the audio type of each channel at the input of the card, and at the ABUS inputs and outputs. Detected audio types can be PCM, AC3 (Dolby Digital), Dolby E or NPCM (other non-PCM). Card Input Channels For Channels 1 to 4, which are the card’s analog inputs, the indicators always display PCM. Channels 5 to 8 represent the card’s digital inputs.
GUIDE TO INSTALLATION AND OPERATION 3.3.7 RALM tab: This Remote Audio Level Meters feature allows distant supervision of the audio levels present at the eight outputs of the UAP-1783. 3.3.7.1 RALM Connections tab CH1&2, CH3&4, CH5&6, CH7&8 – each radio button turns the player ON or OFF for the pair of channels. Reset Counter – reset the overload counter to zero. The counters are located on top of each meter. See Overload Cursor in the Meter Ballistics section for more information.
GUIDE TO INSTALLATION AND OPERATION Color samples – the three samples show the currently-selected color for the upper, middle and lower zones of the meter. Overload Counter - The overload cursor appears on the meter as an arrowhead in the meter scale. The two pulldown boxes set the position of the overload cursor on the left and right meters. If the audio level on that channel goes above the cursor, the Overload Counter at the top of the meter is incremented.
GUIDE TO INSTALLATION AND OPERATION 3.3.9 Reference Input Reference – Desired: Use a radio button to select a reference signal for the UAP-1783. The reference sources are placed by order of priority where ABUS has the highest priority. The absence of the selected reference is an error condition. • Select Auto in the header bar to automatically select the highest-priority reference present and valid. Reference – Current: This section indicates the current reference used by the UAP-1783.
GUIDE TO INSTALLATION AND OPERATION 3.3.10 Rear Type This tab shows the type of the rear panel: single or dual width, and digital inputs/outputs standard. 3.3.11 Factory / Presets Load Factory - The Factory profile is a read-only set of factory-selected values that can be used to return the UAP-1783 to a standard operating condition without affecting the User Presets. • The UAP-1783 Menu in section 3.2.
GUIDE TO INSTALLATION AND OPERATION 3.3.11.1 Profiles Click the Profiles button at the bottom of the Factory/Presets panel to open a window allowing parameter settings to be copied from this UAP-1783 card to other UAP-1783 cards. • The Copy Profile From line shows the current UAP-1783.
GUIDE TO INSTALLATION AND OPERATION 3.3.12 Options Two options are available for the UAP-1783: • UP/DOWN MIXING option (UAP-1783-OPT-MIX) • DYNAMIC PROCESSING option (UAP-1783OPT-DYN) Activate either option on the UAP-1783 card by entering the activation key into the Enter Key data box in its tab, and clicking the Enable Option button. • The current status of the option is shown in the status box below the Enter Key data box.
GUIDE TO INSTALLATION AND OPERATION 3.3.14 Info The Info panel provides the user information about the UAP-1783. The boxes titled Label, Short Label, Source ID and Comments are editable – users can enter their own information. The Advanced button displays: • the name of the server within the iControl system • the frame in which it is installed • the slot occupied by the card • its ID (70 for UAP-1783).
