Hi,
I’m posting this in HTGuide and AVS forum.
I have a Velodyne powered sub connected to my SSP-800 with XRL cable. When I press mute or when a digital input (HDMI/coax) is interrupted e.g. movie pause, transition between menu and movie, I get one or more thumps from my sub. I switched cables from XLR to RCA, switched subs from Velodyne to Martin Logan with no change. Sub is always on and auto on/off feature is disabled.
At higher volumes (50+), with no media playing, I get noise in my SSP-800 sub output, which I can only say, sounds like white noise (no hum, no buzz). At volume 65 (my favorite level for movies) the noise is audible in my listening position. There is no ground loop. There are no cell phones, chargers or PC electronics in near vicinity. I tried different configurations. All digital inputs with sub enabled generate noise in sub output. With analog inputs en digital inputs with sub disabled sub output is dead silent.
With no media playing turning the volume knob up/down rapidly, I hear a rattle of short clicking noises from my sub. The rattle corresponds with every 0.5dB increase/decrease.
Volume of thumps, rattle and noise changes when increasing/decreasing the master volume.
Some other observations:
Oppo BD player (HDMI input) in standby (no noise from sub)
Oppo BD player (HDMI input) on (noise from sub)
Lexicon DVD player (coax input) off, (noise from sub)
Lexicon DVD player (coax input) on, (noise from sub)
As a final test I connected the XLR SSP-800 sub output to my CA-5200 center input. Both center and sub have the same speaker levels (0dB). At volume 60+ the center channel activated the protection mode (blinking red light). Just before going into protection I noticed that noise and rattle from the sub output were present.
What is causing thumps, rattle and noise in my SSP-800 sub output?
I told my dealer, but he has no idea.
SSP-800 firmware 202.
