Audio Connections
The QOR.32's rear panel contains all of the connec-
tors used for audio I/O, Ethernet, GPIO, power supply
and the connections to your iQ frames. Note that we use
RJ-45 connectors for three purposes:
•
Analog audio inputs and outputs
•
AES audio inputs and outputs
•
Ethernet (some with PoE - Power over Ethernet)
It is important to follow the proper conventions for
wiring these connectors and ensure that the connector
functions are not confused as damage may result if you
plug a network cable into an audio input.
Analog and AES Audio
The connector pin functions shown in Figure 1-3 are
the same for both the AES and Analog inputs and out-
puts.
The nominal audio level for analog line inputs and
outputs is +4 dBm. This audio level will provide you
with 20 dB of headroom.
Note: The well-labelled RJ-45 connectors on
the QOR.32 rear panel are used for different

for connection of microphone inputs. These connectors
use the standard wiring convention for 3-pin XLR audio
connectors. These connectors may have 48-volt Phan-
tom power enabled via the QOR.32's web page configu-
ration. Please take appropriate precautions if you con-
nect anything other than a microphone to these inputs
when Phantom power is enabled.
