Stray IR signals affecting equipemt


Recommended Posts

I recently had my B&K pre amp volume increase in 20 seconds 30% till I caught it and shut down A+. I ask on two different forums and one answer was turn off power, unplug from AC and turn the dial back and forth a few times. ( I must mention I live in Albuquerque New Mexico very very dry and highly dusty and hight static. The other forum say stray IR signal could have been the culprit. I played it for 90 mim's each of two days and no problem. There is no reliable audio shop in Albuquerque to take it to and B&K is out of business. Thoughts?

Is the IR receiver very sensitive ? In other words, can you aim the RC well away from the receiver and still have it operate ?

If so, try an adhesive filter of some kind in front of the receiver to reduce it's sensitivity to non direct IR.

How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file.

Bill and Jim - is this with software controlling volume?

Jim has A+ volume set to DAC only, if the screen shot he posted in another thread is accurate. So I don't think it's the same thing that happened to you, Bill.
