Signal Inputs
Analog: 2 channels balanced via 25-way D-type connector

Signal Outputs
Analog: 7 per input channel balanced via 25-way D-type connector
Note: Configurable for 1 input to 14 output operation

Indicators
Power up or CPU fault: Good = Off/Fault = Red

CPU running but input 1 not detected (both inputs or primary input when in single
channel mode): Input detected = Off/Not Detected = Yellow

CPU running but input 2 not detected (both inputs or primary input when in single channel mode): Input detected = Off/Not detected = Yellow

Normal operation with input detected (either input or primary input when in single channel mode): Input not detected = Off/Input detected = Green

Controls
Mode: Single, dual channel

Fine gain adjustmen:t ±0.5 dB additional to the coarse gain level, separately adjustable for each input

Remote Control Functions
Gain (separate L and R): +24 dB to -24 dB in 0.5 dB steps

Silence detect: Level adjustable, - 15 to -25 dBu in 1 dB steps

Warning timer: 1 to 60s (for silence detection)

Logging
Input x State: OK, WARN Silence (L and R)

RollTrack controls: On/Off, Index, Source, Address, Command, Status, Sending

RollTrack:

• Unused
• Input 1 Present
• Input 1 Silent
• Input 2 Present
• Input 2 Silent
