1 CH 1 INPUT - In analog mode, this XLR connector should be sent a balanced, pro-level signal that is heard by callers
when they connect to Opal on Channel 1. This is usually a “mix-minus” feed created on your studio console. In digital
AES3 mode, both CH 1 INPUT and CH 2 INPUT are applied here (on le and right channel, respecvely).
2 CH 2 INPUT - This analog input receives audio to be sent to callers on Channel 2. This input is disabled when in AES3
mode.
3 CH 1 OUTPUT - This analog output will deliver the audio from callers who connect to Opal Channel 1
In digital AES3 mode, both CH 1 OUTPUT and CH 2 OUTPUT are delivered here (on le and right channel, respecvely).
4 CH 2 OUTPUT - This analog output will deliver the audio from callers who connect to Opal Channel 2. This output is
disabled when in AES3.
5 Ethernet Port - Connect your network to this gigabit compable Ethernet port.
6 Contact Closure Connector - This contains 4 contact closure input and output signals, for various remote control and
tally funcons as described further on.
7 Serial Port - This is an RS-232 connector that presents a serial port for future use.
8 Power Supply Input - Apply the included AC desktop adapter output here. The power supply port requires 24 VDC at
0.5 A.
