Hi, well this happens because the "Anti-pop" filter either isn't present, usually they are built into the electronics, or it is and isn't active?
But sometimes whatever is used or on we often still have problems, with Pops crackles etc when changing sources or zones etc.
Now, the best way to fix this type of event, is to install things called poly-switches on each and every speaker leg, the devices have NO effect on sound etc, however will NOT allow fast transients to flow into the speakers, they also as an added benefit protect the speakers too.
Some people only put a pollyswitch at each output leg, at the amplifier, and NOT at each leg at the speaker, either way is just as effective. it just works.

Why won't my Roussand R850MC amplifier play sounds into our multi-room setup?


Sounds like one of the power amplifiers in your Russound has a short. It's not a difficult repair for a good technician. Try a local stereo shop or send it off to Russound.

Russound CA6.4 amp / controller - 3 of the 6 zones can't switch source inputs.


I suspect the inputs will all go into an IC. You just need to trace one of them back till you come across it. Either the circuit around it will be the problem, or more likely the IC itself.

No sound from Russound ss-4 after connecting to BACK surround speaker connections on the 2807.


Check the speaker setup configuration in the setup menu. Many times the surround back speaker terminals can be assigned to something else like zone 2. They may just be turned off.

Russound CA6.4i zones failing


They should be. I would replace the electrolytics for each of the failed zones. If you do not have a tester, just replace the electrolytics out of hand. The intermittent sound suggests one is likely shorted but not completely or has opened up internally- but not completely.

What causes cracking, popping sounds on most zones of a MZC 66 amplifier controller?


Try this to isolate where it is coming from. Either the zone amps are defective, which is not likely, or the main amp is at fault. Hard to believe they are mis-wired, they typically are foolproof in this area.

At the main controller, try the two zones that are good and plug them into the 4 bad zones one at a time and see if you get the same symptom. If you do, then it is not the main controller and something common to the 4 zones is causing the issue. If they are wireless, then you my have interference so check if you can select different channels.

Honeywell ST6400C programmer doesn't switch off


Since you have three on/off timing modes could there be an overlap in the times?
The wires in the unit might be crossed. (don't always assume the contractor who wired maintained the correct colors , I have a friend who blew out a heating pipe because when a replacement motor valve was installed it was never wired right and the plumber assumed the colors were correct so no overtemp shutoff created steam in PVC pipes, OPPS)
There fore maybe one is still coming on. Do you have more than one heating zone? IF so see below

I guess the main question is why manually turn it off? why not use the program.

I will assume your heat is know as forced hot water heating. My house is multizoned however when the zone calling for heat turns off (zone valve closes) I installed a bypass valve in the lowest zone in the house, and reduced the circulator low shut off temp to 130 F which means even though the heat isn't on my circulator will continue to run dumping this excess heat in the lowest part of house to rise through house. (the spring loaded water valve allows the heated water to flow into this zone )We do have two thermistats. And even though the lowest one is not calling for heat the radiators are hot when the excess is dumped into this zone. So investigate and see if your system might be similar. (multizone).

Investigate your wiring, reprogram, replace any battery backup.
