9. Reverse the phase of the audio input at one of the XLRs (by reversing the wires connecting to pins 2 and 3) and verify that the PHASE indicator LED is illuminated RED. This is a test for
10 .Insert a true stereo signal at the XLR inputs and verify that the PHASE indicator LED is a flickering green to amber color. This is normal for a stereo signal. The amount of RED or GREEN in the PHASE LED is an indicator of how much phasor information is present in the monitored stereo signal.
11 .With analog audio present at the balanced XLR outputs on the rear panel, verify that the SIG indicator LEDs at both input and output are illuminated.
12 .(Steps 12, 13, and 14 are for
13 .Remove the Digital signals and verify that the LED illuminates RED on both the front and rear panels.
14 .Place distinctive audio signals at both the Analog and Digital inputs and then toggle between the Analog and Digital sources via the front panel using the A/D SELECT button.
