20 Most Recent NAD T765 Questions & Answers

Could the amp be showing distress, clipping, going into protection? There really isn't much reason for volume of a digital input to have an effect unless the room is shaking so much it's upsetting the digital source device's tracking.

The lamps may be burned out. Try replacing lamps.

If it sounds normal, then yes leave them as they are.

But there may need to be an exception made.

The distances are set the way they are for the proper advance or delay in milliseconds of the sound arrival at the listening position.
The system calibrated your speaker settings based on how each channel's frequency responses measured at the listening position. Room acoustics and channel positioning greatly affects this. The settings it made in the system can be a best case scenario compromise that MAY not be good for your surround speakers as it can be delivering signal to them that they were not designed to handle; in which case it is best to increase the crossover value of those speakers.

You have a fault in the power amp. Identify the faulty channel by following the input leads. As, a stereo amp is basically two mono amps put together. You can compare the bad channel with the good one. First thing to do is a visual look around. If you see something odd looking in one channel and it's the faulty one, compared with the good channel, you might have found the cause. Look at the devices or device on the heatsink especially. If nothing stands out, the next thing to do is test the channels. You can do this in two ways. First, by touching the parts on each channel (with power on) with an insulated screwdriver. If you get a buzz in one channel and nothing in the bad one, in the same places of course! You might have located the faulty device. You can do the same with a volt meter. The readings should be the same in each channel. Work forward from the end of the preamp stage. Don't bother with the power supply parts, as they are common to both channels. By the way, don't short anything!

It is funny, I was just reading an article today about New Acoustic Dimension Cassette decks saying they were top of the line and equal to Nakamichi. The most likely reason is that the volume control needs cleaning with Electrical Switch Cleaner. You would have to remove the case and look. It is worth a quick spray. This says it has a motorized volume control. https://www.google.com/search?q=nad+1600+receiver+volume+on+high+volume ..

You can find volume and balance control components for the NAD 1300 preamp from a variety of sources. You can check with NAD directly, or look for parts on websites such as eBay or Amazon. Additionally, you may be able to find parts from audio/electronics shops in your local area.

NAD (New Acoustic Dimension) was all the rage when I was into composite audio in the 1970s. Not sure why would want to tweak that sweet clear natural sound like the performers played it. Your problem will be that you are loading an amp to a pre amp. https://www.google.com/search?q=Nad+2600 https://www.google.com/search?q=Nad+3020 https://www.google.com/search?q=nad+3020+nad+2600+graphic+equalizer ..

Does it occur on both channels at the same time, (power supply) or independant channels, (coupling capacitor).
