Re: nad 302 amplifier

Sounds to me that the vol control has lost its earth end connection So yes its a problem with the dial control You couls try some contact cleaner But better still lift of the lid and base if possible while the amplifier is not plugged into the power socket and see if you have a dry joints around the vol control pot regards Trev

Try unplugging all of the speakers and see if that amp is still distressed. If it looks clean and happy start adding speakers until it returns (or not).

How do you connect a nad c270 amp to the bose 901 series vi equlizer and system/

Bear in mind that 901's require exclusive use of any amplifier they use. You shouldn't expect to use conventional speakers alongside them on the same amp. The reason is that the 901's require the use of their dedicated Active Equalizer to shape the frequency spectrun to match their drivers' response curves, resulting in a flat sound output. Applying that kind of equalization to any conventional speakers will sound to sharp at the extremes and may even potentially damage them.

For connection I would run a pair of RCA cables from the L&R Audio Line OUT of whatever preamp or source you're using to the Active EQ's Line IN; then the EQ's Line OUT to a NAD amp's Line IN. DEselect any Tape options on the Active EQ, attach the 901's to the new amp, set the NAD volume controls pretty high (and leave them alone), run through any level setup procedures in your control electronics for volume, etc and you're done.

Connecting NAD 2600a amp.

Never connect incompatible connections. Speaker outputs are for speaker inputs. Period.

The various inputs on this or most any amp are for Line Level signal with the exception of anything explicitly labeled "PHONO" as that would be for a non-preamplified turntable ONLY.

From what I have found online, Lab-In was a NAD feature that restored the frequencies that were rolled off when turntables were being used in the (assumed) preamplifier that fed this amp.

"NAD belleived at the time that practical PHONO stages and the preamp and power amplifier stages be rolled off at subsonic frequencies to prevent subsonic wow and flutter from Turntables and supersonic frequencies (EMI/RF/Radio) signals from getting into the system in the first place. Their notion was that if your ears cannot physically hear it, then why amplify it. For the PURIST, there were a set of LAB IN amplifier inputs with more extended response called "LAB IN" inputs"

Use the Lab In's UNLESS you have a turntable source.

Right loudspeaker problem

Doesnt sound like the selector as it "sometimes" works. Redo the speaker connections on the back of the amp and speakers first. If it persists, swop the speakers and cables, if the problem swops, then it could be inside the speaker or the cable, if still the same then amp has dry joints/loose connections probably

PreAmp to Amp problem

Sorted it. You have to put the plugs back in the PreampOUt/Main in or it cuts out the pre-amp.

NAD C370 Amplifier

This sounds like a problem with the protection circuit, and/or the speaker relays. More specifically, a capacitor within those circuits that is not behaving properly. I strongly suggest having it looked at ASAP.

NAD 302 Amp

Try Earex wax softener, worked for me! Seriously though, are you sure it's the amp, could someone have cooked your speakers without you knowing? Have you checked the media source? Garbage in equals garbage out with any system. Your terminology leads me to think you are an audiophile, so have you checked the stylus? Have you put in some new furniture or rearranged the room. This can make a big difference to the way a system sounds. Check all the usual things like your signal connections. If you have a PC to hand in your listening room, use it as a sound analyser, plug a microphone in and connect the line out into your amp you should be able then to measure the responses of your setup with white noise, swept tones and impulses for room dynamics. I seem to remember there are freeware utilities for this kind of thing. Good luck
