2.0 Pre-configured Systems
Units in the initial engineering deliveries have been pre-tested and already setup to stream using AES67.
Please follow these steps to setup the system:
1.
Connect the EQ3-AoIP analog outputs to the power amplifiers.
2.
Connect a source to the AP25. Currently HDMI IN 1 is setup as the source.
3.
Optionally connect a DTV to the AP25 HDMI OUT for video monitoring.
4.
Connect the AES67 Ethernet port on the AP25 (the one on the option card backplate; not the one
labeled Ethernet next to the SERVICE PORT) to the AES Ethernet port on the EQ3 (the one next
to IN3/IN4 cut out; not the one labeled Ethernet.) The connection may be made through a Gigibit
Ethernet switch, or with a direct Ethernet cable.
5.
Power up EQ3-AoIP and AP25. They can be powered up in any sequence.
6.
Power up the audio amplifiers.
7.
Once EQ3-AoIP and AP25 completed their startup initializations, audio should be passing
through. On some occasions audio streaming does not start up immediately due to some AES67
network negotiation issues, but they will resolve themselves in a few minutes.
2.1 EQ3-AoIP Analog Output Configuration
The EQ3-AoIP routing configuration is shown in the following screen capture of the EQ3-AoIP
configuration screen. The numbers on the left are the AES67 channel numbers for the AES67 stream.
The numbers on the top are the EQ3-AoIP output channel numbers. However, the pre-production EQ3-
AoIP does not have the correct silkscreen marking on the back panel. Output 1 is simply marked as 17,
output 2 as 18, etc. LF is low frequency crossover filtered output, MH is mid frequency, HF is high
frequency, and FR is full range monitor outputs.
