Grass Valley 8920ADC v.2.0.1A - Manual (Page 10)

10 8920ADC Instruction Manual
Installation
Cabling
Note At the back of this manual are overlay cards that can be placed over the rear
connector BNCs to identify the specific 8920ADC connector functions.
Input
Connect a balanced input source to the stereo pair input terminal block (see
Figure 3 ).
CAUTION The input signal must be balanced. Connecting an un-balanced input signal
at high signal levels may damage the input receivers.
The 8920ADC can produce a full-scale output from an analog audio input
signal level of +12 dBu to +28 dBu.

Outputs
The 8920ADC has four AES/EBU serial digital outputs—J5 through J8. The
destination equipment should have a 75
Ω input impedance or loop
through inputs that are terminated into 75 Ω .
Reference Inputs
Loop-through input BNCs are provided for the required 48 kHz AES/EBU
reference signals. Terminate the looping BNC into 75
Ω if not used.
