D.3 - Testing and Troubleshooting the AMR Active System
Please use the AMR Test & Burn In CD's channel identification track to verify that your system’s channel
assignment is correct.
If the low frequency channels have been mixed up the channel identification sequence will have the high frequencies
coming from one channel with the low frequencies from the other. In this case please switch around the
interconnects or speaker cables (one OR the other, not both) for the power amplifier. Please power down the all
amplifier(s) before breaking and re-making connections.
If the sound lacks severely in high or low frequencies and either high or low frequency driver remain silent,
please check all connections between speaker, amplifiers and CCE again and compare to these notes and the
included drawings.
Play some music with a large amount of high frequency and low frequency content. If the high and low frequencies
appear rolled off, please check that the speaker cable connectors labeled CCE are attached to the AM-77 CCE
and that the speaker cable connectors labeled AM-77 are attached to the AM-77(s) configured as power
amplifier(s).
