Excess clipping on nad 372 amp

It could be anything from a blown fuse from a power surge to a shorted capacitor ijn the power supply. There are fuses in all amplifiers. Locate it and test it with an ohmmeter.

Does the TV have a line audio outpot (red and white jack)? If so feed the amplifier input from there.

You are probably clipping in that midrange. Since the DVD player is fine and CD player is distorting: they are line level outputs, If you are running those through an equalizer- the equalizer should allow you add in a 10db attenuation.

If you are running them straight to the amp, The CD line level output should be about 1.5 volt peak to peak, it may be the line level input of your amp is only 1 volt and the DVD player simply has that level of output so does not clip..

Simply adding into the cable a 0.1 microfarad polyester capacitor for each channel should be enough attenuation to avoid clipping. The midrange is where you hear the most content in large part because that is the range that the human ear is most sensitive to. Which is why that portion clips. The DVD audio is actually recorded to the same specs as CD audio. You can confirm this by playing your CD disk in your DVD player. .

You DO realize the preamp is duplicating stuff in the Nad C372, right? This Preamps adds nothing but PHONO connectivity and control. That's why they're called "preamps".

Model 2100 Picture and article:

Use the Sub Out pair on the Preamp (joined by an RCA Y-cable) for the Sub Input on the sub (duh):

Run RCA from the Preamp Main Out to the C372 Aux In to hear any sources attached to the preamp.

Or, if you don't NEED the preamp because you don't have a turntable,ditch the preamp and connect the sub using the speaker outputs on the NADS, according to the manual.

Hiya, did you try to swop the inputs as well and see if the problem swops. Try that as the input could also be low. If so try change the cable.

If not there try cleaning out the balance pot with switch cleaner (have to open to that and only you are comfortable).

If thats not there then likely an internal problem and will have to send it in.
Best of luck

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

The unit is detecting a problem and shutting down in what is usually called "protect" mode. Look for bad connections on the board near the voltage regulators.

Hi Marie, still need someone to connect it up for you? I could talk you through it.

Hello Robert,

If the standby/protection indicator on the amplifier blinks when you specifically press the volume +/- key, it obviously indicates that the unit is receiving the remote's command.
Try the following while pressing the volume key on the remote:
1.- Put your ear as close as possible to the volume control knob and listen for the sound
of a motor spinning, if you hear it, the volume control assembly needs repair. If you
hear no sound, proceed to next step.
2.- Gently rotate the volume control knob on the amplifier unit (it might be stuck and
needs a "little help").

If none of the above applies, the unit needs to be opened and troubleshooted. I've seen many instances where the volume control motor was not properly connected to the board or the assembly was put back incorrectly (specially in units that have been opened to be refurbished). I've heard NAD has a limited warranty for refurbished items. It might be wise for you to check before sending the unit for repair at your expense or trying to tackle the problem yourself. Hope this helps.

Unplug for 20 min. and then plug in to try and see if it will come back on.
