How does the SSP function work?
SSP (surround sound processor loop) completely bypasses the preamp circuit by connecting the SSP input directly to the preamp output. If a 2 channel amp is kept in the system, both the surround sound processor and the preamp can be used without having to reconnect anything when switching between music listening and movie watching. The center, rear, and subwoofer channel outputs from the processor go directly to a three channel power amp, but the main left and right outputs from the processor plug into the SSP input on the preamp. 17. Why is there a lot of buzz / hum only in SSP mode? In SSP mode the preamp is completely bypassed. If no problem exists in regular mode, then the hum is originating from another source. In home theater setups, ground loops are a common problem. The loop can be traced by unplugging the components one at a time until the hum disappears. The power cords should not be plugged back into the same outlets. If the buzz disappears only when cable TV is disconnected,
