2020ADC 4-Channel Audio
Analog to Digital Converter
Introduction
The 2020ADC converts four channels of analog audio to two balanced or
unbalanced digital audio outputs. All signals are connected via the corre-
sponding passive rear module in the back of the 2000 frame. The four chan-
nels of analog audio enter via plug-in terminal blocks. A 48 kHz AES/EBU
reference, connected to the loop-through input BNCs, is required to lock
the module. Digital outputs are available through 75 ohm BNCs (unbal-
anced) or plug-in terminal blocks (balanced).
The 2020ADC can modify the incoming gain of each analog channel and
provides a choice of output modes.
The 2020ADC features:
•
AES/EBU loop-through reference input,
•
48 kHz sampling rate,
•
24-bit quantization,
•
Conversion of four channels of analog audio,
•
Two 75 ohm (unbalanced) or 110 ohm (balanced) outputs,
•
Choice of output modes include normal, channel swap, phase invert,
channel summing and tone,
•
Independent input level control from +12 dBu to +28 dBu,
•
Remote control and monitoring, and
•
Remote control lockout via onboard jumper.
