Fig. 4: Digital INPUT Bypass
A 3 pin female XLR AES/EBU [11] (AES 3) input and a 3 pin male XLR
LINK output [12] is provided.
The balanced input utilizes a transformer and is electrically isolated.
The digital LINK output may be used to feed a refreshed input signal to
the next device in the system signal chain. The signal shape (the rising
and trailing edges of the signal) and level are refreshed with an analog
signal amplifier.
A power fail relay is incorporated to prevent interruption of the signal
chain should there be a power failure. In this situation, the digital input
signal bypasses the analog buffer amplifier and is routed directly to the
LINK output.

WARNING!
The amplifier's output pins can carry dangerous voltages.
- Only use isolated loudspeaker cables with correctly mounted
connectors. Otherwise there is a potential risk of electric
shock.
- Never connect an amplifier output pin to any other in or
output connector pin or earth (ground). This might lead to
electric shock or damage the unit.
