Sound cutting out from right channel

Kw6 · « **on:** 8 Jul 2018, 01:09 am »

Hi guys

I recently purchased a BC Acoustique 362d class A integrated amp. When I change the volume with remote the sound cuts out from right channel and drifts to left channel for a split second and them comes back to center. Sometimes while listening to a song the sound cuts on in right channel for half the song. Problem is never with left channel. Also two times I can recall when I turn on amp right channel is dead. I need to turn on amp on and off to get it back. I sent it back to dealer to fix and they said they can't find problem. They said played for days no problem at all. Keep in mind the volume control has a series of resistors not a volume pot like Alps.

What could be wrong as I am using a tube amp right now no problem and using remote but they use motorized alps. The dealer starting to say it's my equipment.

Please help diagnose?

From your description I would say there is a problem with the right channel amplifier in the unit. I would contact the factory and explain the situation to them.

It's at the dealer now they are authorized service centre and they say it's fine. They said they played it for days with no problem. Could it be the volume control?

As part of a process of elimination, try swapping the inputs, so that left source output goes into right amp input and vice a versa with the other channel.

If the problem is still in your right channel, you've at least ruled out the source. If it's now in the left, you're closer to locating the prob.,somewhere in the source.

Does it cause a distinct pop in the speakers when it happens, or is it a sort of quiet drop away and return?

It's not my Cambridge 851n networked player or my cables or speakers as I have been playing my system every day with my integrated tube amp and no problems ever since I sent amp back for service.

There is no pop sound. As I press volume up on the remote there is a click sound and sound is lost in right channel and you only hear sound from left and then it restores itself in a instant. What is more worrisome is that during a song with no touch of volume remote the sound crackles a bit in right channel and was off for at least 2 mins before it came back. And one time I take it off stand by and come back 15 mins to to start playing music and right channel is dead. I had to turn off and on to get it back on both channels.

My wild ass guess is that there is a tiny break somewhere in the amp's right channel circuitry that may be affected by operating temperature or a slight flexure of the mounting structure.

I thought about that too as I said two times I play amp and right channel dead. Turn on and off and it comes back. But their tech said amp checks out and they play my amp for days no problems like I described. Either they are lying cause they know tuff to fix or need to replace.

Options:

1.) Get a new amp
2.) Get a new repair shop
3.) Sell amp to the "repair" shop

I will try to get it fix as it's only a mth old! Then sell it down the road!

If it's only a month old and you're working with a legit dealer/seller, they should either fix or replace it. Oh yeah, or let you return it for a refund. I've had similar problems/symptoms in past that ended up being cold solder connections or even a dirty selector switch. JLM mentioned a few other possibilities as well. I don't it's anything earth shattering, but it would take some diagnostic knowhow. The true acid test would be for your dealer to send you a loaner integrated amp to swap into your system. If the loaner doesn't have any issues, your current integrated has a legitimate problem.

Well I know for sure it's not my gear because as write this post I have been listening to my system since 1 pm today no problem. I'm west coast!

Initially dealer said it could be a cold solder joint but they email me tech found nothing wrong and they played my amp for days with no problem. Btw I used a small fan to blow air from left side of amp to right side. Could I have triggered protection circuitry on right channel? Fan was 3 ft away from left side of amp which sat on the floor.

I never asked for refund yet but I did say since I have problem so soon after purchase you should replace it he said no they will warranty it for period of two yrs. I doubt he will give me refund but I will call him on Wednesday when they open up.

I mean say asking refund to the card company or Paypal.

OK, sorry didn't realize you had a replacement integrated. Case closed then.... your new solid state integrated has issues. Your dealer should step up and take care of it.

Yes I have another amp to use from my own collection and I have been playing audio ever since I sent it away. So I know it's not my stuff. Believe I made sure before I packed that 60lb amp.

Yes Fullrangeman I purchased with visa. What legal recourse do I have to ask for refund? I am willing to forgo the shipping charges and maybe even 10% restocking fee if necessary. I feel I got a lemon and it's going to take a lot to fix. But why would he like say working fine at his end for days. Before I sent off amp I took it off standby waited 15 mins and started streaming right channel wouldn't come on so I said f this and packed it up. So I thought when he turn it on it would be dead too but apparent it was ok for him which I don't doubt as when I turn on and off it came back too. But while he had it it should have at least cut out once but he did not mention. That's why I'm perplexed!😑

Btw I will call France tonite to talk to head office to see what they say. Last time I email them they told me to deal with my dealer who is auth service centre for their products.
