[QUOTE="West, post: 7918505, member: 638770"] Today I switched my set up over to 8 way active using the p99rs. Using it in 6 channel operation, I had 0 problems. After we ( [USER=637354]@double 07[/USER] and I) hooked it up to the MCC406M we started seeing the powerguard lights flash. We hooked up the suspect channel to a DD1 and it shows that there is distortion, which is also causes the powerguards to flash. I did some more investigating and it appears there are two channels (mid right and mid bass right) which are giving distortion at a volume of >40 or so. If I try to run the deck at lower than 40 and increase the gain, the distortion is amplified by the Mc and the powerguards come back on. I tried reducing the Pioneers SLA (individual source level adjustment) levels, helps but the distortion is still there. Triple checked the RCA connections... even replaced the RCA's and the distortion is still there. Tried using digital attinuation at both high and low settings. Anything else I can do, or is sending it off for repairs the only option? The original owner claimed that he used the deck to check amplifiers. Double 07 suggested that the guy may have damaged some of the circuity by unplugging the RCA's which they were running and connecting/breaking the live circuit damaged them. I am agree with him, but wanted to double check to see if anyone had any other suggestions. Thanks... [/QUOTE]
