I bought a foreclosure home that was pre-wired with a 6 zone home audio system. Well as you can imagine, all of the equipment is gone and the bank/realtor have no clue what was originally in the home. The only bits still left are the six pairs of ceiling mounted speakers and the volume control knobs.
Here is what was left of the system:
1) The six zone volume controls. ( Quam-Nichols "QC-10")
-- QC-10 Classic
2) The house wiring which seems to be a two-wire system (green/red)
I consulted with a AV installer on the best way to get this working and he gave me a few recommendations.
I purchased the following new equipment:
1) Russound R1250MC
2) Six new Russound 126w Volume Control
Well, the installer came over yesterday and now I have a few serious issues:
1) I cannot mute the volume in any of the rooms
2) The volume does not correspond correctly to the number on the dial. It seems like the volume barely registers between 1-5 and then from 6-10 seems to step up drastically.
The installer did not install the new Russound 126w Volume controls because he could not get them to mute. At the time he was here the older QC-10 seemed to be muting but not it seems that the QC-10 do not mute either. He tried to to figure out a way to split the two wire system to get it to mute on the new Russound 126w Volume control but could not. He said the issue was that our two-wire system is causing the problem and did not have any solid recommendations on how to salvage the system without rewiring to four wires.
Now that it is a new day, I was thinking the following might be the best solution:
1) Have the newer Russound 126w Volume control installed to fix the volume stepping issue.
2) Find a way to connect and disconnect source at the amp in order to mute the system and shut down the Zone.
It is a crude fix but do you have any additional ideas?
