Hey all,
I'm having some trouble with my beloved Rotel RMB-1095
- Turn Power Amp off
- Set Preamp gain to 40-50
- Turn Power Amp On
- No sound at all
- Turn preamp gain to around 65 and the sound is just audible, above 75 or so and the sound is clear and crisp with normal volume
- Lower Gain to 50 and there is still audible sound without any issues
- Turn Amplifier off (with gain still on 50)
- Turn Amplifer back on after a few seconds and there is no sound at all
I tried the same steps with 3 different rca cables, and the same thing happens on my rsp985 processor too. Can replicate it on any combination of equipment. I can replicate it on the spot very easily.
Extra Notes
What normally happens when amp power button is pressed on (turning amp on)
All 5 Protection lights come up for a second then switch off (as part of a protection test)
What happens when I turn I press the power button off (turning amp off)
When you go to switch the unit off the Front Left and Surround Left channels flash for about 1 second and then switch off (the others do not turn on during the shut down of the rmb1095. I confirmed with my mate who also has a RMB1095 that none of his Protection lights flash on when you press the power button.
I have been told that it could be the input relays not contacting, turning up the gain seems to "semi" contact internally and turning it up a bit more seems to make it perform fine once the gain on the preamp is at around 65-70db.
Any advice/help on the matter would be hugely appreciated
