5.2.2 Audio input and output connectors
The rear panel features eight installation specific Phoenix
Euroblock connectors with the following assignments:
▪ four analog inputs (A1 - A4)
▪ two digital AES3 inputs (D1/2 and D3/4 - four channels) with
corresponding LINK outputs.
Each input channel can be routed to any of the output channels A
to D
Þ
Input routing.
Analog INPUT (A1 - A4)
A 3-pin Phoenix Euroblock connector (male) is provided for each
analog input to accept the supplied 3-pin Phoenix Euroblock
connector (female). To feed (link) the input signal on to the next
device in the signal chain, the connector can also be used as a
cable tap.
Specifications
Pin assignment ( ) GND, neg., pos.
Input impedance 32 kOhms, electronically balanced
CMRR @ 100 Hz/1 kHz/10 kHz >80/>80/>70 dB
Maximum input level (balanced/unbalanced) +25/+18 dBu
+27.3 dBu @ 0 dBFS
Digital INPUT and LINK (D1/2 - D3/4)
A 3-pin Phoenix Euroblock connector (male) is provided for each
pair of digital inputs to accept the supplied 3-pin Phoenix
Euroblock connector (female).
The corresponding digital LINK output (1/2, 3/4) can be used to
feed a refreshed input signal to the next device in the signal chain.
The signal shape (the rising and falling edges of the signal) and
level are refreshed with an analog buffer 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.
