SOURCE: Speakercraft DBB12100 Amplifier, Circuit problem

Sounds like its a problem with over heating. open unit clean out all dust and dust bunnies wich compressed air. check that all fans are opperating. (fans on 6x100 amp units or thermal controled). If amp goes into protection prior to fans turning, there is your answer. the @ power supplies will have a green light on the output side. if the light in on power supply is good. or you can check that the output voltage is at 48Vdc on both units.

SOURCE: I have Nuvo Essentia D amplifier. Worked for 6

The clicks are generated by 2 causes:
1 - the arrival of the electric current thru the amplifier circuit in the speaker in a large amount- it's supposed to happen, after that the current drops to the stand-by value very quickly. If a zone doesn't click then the amplifier of that zone has failed and when connected it draws so much power that the overall voltage drops so low that the processor of the unit is no longer capable of working and the system freezes.
2 - inside the unit there are also small relays that are used to power the amplifiers on command . If one of them is shorted the corresponding amplifier will not work and the relay will draw a lot more current than usual.
From what you describe it appears that several amplifiers hare in different states of failing: 3 completely, 2 already has secondary bleeding and is close to complete short, 4 has just started to fail. The unit will have to be tested, the failed amplifier circuits replaced and the power source inspected for damage. The job isn't complicated but it requires a basic electronics experience.

SOURCE: 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.

If your installer is an authorized agent or dealer of speakercraft product, it has a 2 year warranty. What type of problems are you experiencing with the system? Do you have a single 8 zone system or are you daisy chaining two units? post a comment, and I can do some research for you. I am an integrator and it's quite possible to have system failures do to a number of causes relating to all sides of the product. Firmware, Software, Hardware, Programming, as well as power failures and wiring issues all can play a part in creating a real headache. I have had systems in the hundreds of thousands of dollars crash due to one conductor of one wire in a 30,000 + sf home. And it is very time consuming as well as aggrivating to all concerned. If I can help in any capacity, I will gladly do so. If your installer has your confidence, that's 80% of the battle.
