This unit is capable of reporting signal information and errors via an Ethernet port or serial port. The chassis is made up of up to two power supplies, a controller board and two MADI bays. The system usually arrives with a single power supply unless a redundant one has been ordered.
Page 12 The audio signals that make up the MADI streams will come from or be delivered to the input and output connectors as AES or analog signals. The MADI Output board receives 32 AES pairs that are individually analyzed and synchronized to the digital audio reference (DARS) and are processed into a MADI Stream that is available at the BNC and Fiber outputs.
Page 13: System Setup Information
Unbalanced AES Inputs and Outputs will have 10 signals per input or output board making up 30 of the 32 pairs used in a MADI stream. The last two signals come from or are delivered to two BNCs located on the MADI board rear panel. In this configuration (unbalanced inputs) the SW1 switch #4 should be toward the CFG B silkscreen (“ON”...
Page 14: Balanced Aes
Balanced AES Inputs and Outputs will have 10 signals at the first board and 11 signals on the next two boards (10+11+11=32) making up 32 of the 32 pairs used in a MADI stream. The last two signals come from the last two I/O boards. In the balanced inputs configuration, the SW1 switch #4 should be toward the CFG A silkscreen (“OFF”...

Analog audio Inputs and Outputs will have 10 signals at the first board and 11 signals on the next two boards (10+11+11=32) making up 32 of the 32 pairs used in a MADI stream. The last two signals come from the last two I/O boards. In the balanced inputs configuration, the SW1 switch #4 should be toward the CFG A silkscreen (“OFF”...
Page 16: Madi Configuration
MADI Configuration The MADI I/O boards have some configuration options that are setup with the dipswitch SW1 found near the middle top half of the board. These should be preconfigured at the factory before shipment. Table 1-1. MADI Input Bd...
Page 17: Madi Terminal System Boards
AES Audio Input (121360-1) The AES Audio Input board receives up to 11 AES signals that are passed to the MADI Output board. The number of signals passed is determined by the slot the board is installed in and the type of rear panel interface used in the system.
Page 18 (this will be set at the factory before shipping). AES Audio Output (121361-1) The AES Audio Output board receives up to 11 AES signals from the MADI Output board and individually drives them to the system rear panel connectors. The number of signals passed is determined by the slot the board is installed in and the type of rear panel interface used in the system.

Page 20: Dac Audio Output (121372-1)
DAC Audio Output (121372-1) The DAC Audio output board receives up to 11 AES3 signals that are passed to the MADI Output board. These signals are individually distributed to the digital to analog converter outputs and after conversion to analog audio are then driven to the system rear panel connectors.
Page 21 5% tolerance. This board will drive high impedance loads (e.g. 100k ohm). In instances when a 600 ohm load needs to be driven, the factory can make a gain adjustment to this board to provide the appropriate level. MADI Terminal 1-11...
Page 22: Madi Input (121362-1)
Controls include SW1 and P1. SW1 is an eight pin dipswitch that utilizes switch 1 to determine if the MADI board is configured as an input or output. Switch 2 indicates the MADI input interface as fiber or unbalanced BNC. Switch 3 indicates the group of 16 signal detect LEDs as pairs 1-16 or 17-32.
Page 23: Madi Output (121362-2)
The MADI Output Board is a transmitter for a Multichannel Audio Digital Interface (MADI/AES10). The MADI transmitter supports 64 channels of 48 kHz digital audio. The 32 AES3 signals are inserted into a MADI stream and output to the 75-Ohm BNC and the Fiber port located on the MADI rear panel.
Page 24 DS1-8, 13-20 (SIGDET1-16) -> Signal detection LEDs (green). This is illuminated when a valid digital audio signal is detected on the associated receiver input. Note:The ADC inputs to the MADI output board provide a ‘no audio’ AES signal when the audio level is low or not connected that will illuminate the signal detect LEDs.
