Popping noise

[Lynn68 66]

I have an fx-audio dac-x6, an art eq341, carver c-1, carver tfm-22, klipsch rp8000f ii, and a belkin power strip. When I hooked up my speakers and equalizer I started getting popping noises when my ptac heater, ac turns on and off. Does anyone have any ideas or what I can do to stop this.

This is caused by high energy distortion harmonics when the current draw on the house suddenly changes. This could be mitigated by ensuring the branch circuit on the audio equipment is far down the column of breakers in the breaker box. Typically, high power appliances like heaters and stoves are wired closest to the Main breaker. If your audio and heater are on separate branch circuits and they are far apart in the breaker box, then you could try a very high quality power conditioner, preferably one with an autotransformer for voltage regulation.

Thank you. I have been reading a lot about this problem and came up with the conditioner but hadn't came across anything about using an auto transformer. And yes you described exactly what I needed to hear. Any suggestions about one?

You could start with trying power conditioners, but I'd just call Crutchfield or Furman and talk to a rep and tell them exactly what you're experiencing and they might have a solution on the shelf for you.

 

I have a Monster AVS 2000 but you can only find those used.

@Lynn68 @Nahash5150 Furman has a few Advanced Voltage Regulators / Power Conditioners.

 

One is the 15A Prestige Voltage Regulator, 120V (P-1800 AR)

Another is

20A Prestige Voltage Regulator / Power Conditioner (P-2400 AR)

https://furmanpower.com/products/p-2400-ar

 

And

Merit Series 15 Amp Voltage Regulator (M-8X AR)

I purchased,

Conditioner Power HT 15A Power Factor (ELITE-15 PF I)

https://furmanpower.com/products/elite-15-pf-i

It does not have voltage regulation.

 

According to most of the specs for the above three units the "Regulation capture range: 97 VAC to 141 VAC, Output Voltage: 120 VAC ±5V"

 

I might opt to revisit these units in the future because I wish to upgrade another system.

Talk to a rep. About 99% of 'power conditioners' on the market are 100% gimmick.
