7 Speaker Sound Check
Use the circulating noise generator of the Surround Processor
to confirm that all channels have output and that each speaker
is connected to its corresponding channel.
8 Speaker Phase Test
This procedure uses the Surround Processor to route the
phase tester's output to the appropriate channel for test. Using
a "Y" adapter, connect the phase tester's output to both
channels of the TAPE or AUX input or any available analog
input. Select the input making sure that the processor is set to
the analog input you have selected, use the Surround
Processor's volume control to set the test level. Select PARTY
or 5/7 Channel Stereo Mode to route the test signal to all
speakers. It may be necessary to adjust the volume or mute
certain channels to get a clear and accurate test result.
