NAD C740 no longer reproducing music through loudspeakers

Attempted to connect imac computer to NAD stereo (with RCA cable), in order to hear internet radio broadcast through my stereo system I tried plugging the RCA cable into each and every connection in the back, to see which one sounded the best. The connections I plugged into include: aux, phono, tape, and either pre out or main in. I think the problem started after plugging into the pre out or main in. I unplugged the RCA cable after hearing a faint pop. Now I can barely hear any sound out of my loudspeakers, unless I crank the volume to maximum. Even then, the music is extremely faint. However, I can hear the music perfectly when I listen through my headphones. Nice and loud... The small glass fuse inside receiver looks fine.

Re: NAD C740 no longer reproducing music through...

What was your amp? ic or transistorized? the output transistor of your amp may be opened, mostly it will short but because u still hear sound, maybe open and only the driver transistor are working. replacing output transistor or IC could solve the problem.

What is the best cable to connect nad7050 to a pc in 24' length?

Stereo shielded coax. BT3002 would work very well as it is double shielded micro-coax, so it is small enough for two cables to fit in to the shield jacket of a 3.5mm plug.

Connecting your computer to an amplifier to play music

Do you want to connect your computer to a amplifier or surround sound, and play music from your computer through the amplifier? If that is the case, you will need to get yourself a cable from your local sound shop. Ask for a "Stereo to RCA" cable. Plug the stereo jack into the back of your computer (where you would normally plug in your desktop speakers) and plug the RCA cables into one of your open channels on your amp. Select "CD" on your amp if you pluged it into the CD channel, and there you go

My NAD C350 plays very faintly. when I turn the volume dial to the max position, I can bearly hear the music. I can hear properly from earphones output. Thanks

Take care. First put the volume down complete. Then unplug the head phone and than try to raise the volume. Could be the headphone connector does not switch through correct. Could be the connections between the pre and power amp are not in place or not proper pushed in?
Always take care when working with amplifiers. When switching them on with volume to max, you easy can kill your speakers. Also when disconnecting the headphones on full power kan damage the loudspeakers.

How to connect an MP3 Player to NAD C320?

You will need a cable with headphone jack (for mp3) and RCA left/right to connect to your NAD 320. You can connect to CD or AUX in the back and then you will need to change the input with remote or with on board buttons to CD or AUX depending where you plugged it.

How do I connect a Mirage Omni s-10 Sub Woofer and a Parasound Model 2100 Pre Amp to the NAD C372 Amplifier?

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".

Register and download the manual for free at

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.

Hi is it possible to connect a laptop to a denon 700aedab for music playback

HI, very possible. Just follow this instruction:

All yo need to use for the connection is to get an RCA TO STEREO JACK HEAD (use the google image to see the type of cable).. Connect to denon 700aedab, make sure that the denon 700aedab is on either aux, tunner,video,etc. Those auxillary options on your denon 700aedab.

Connect the RCA into the aux of the denon 700aedab and connect the small jack head into the laptop ( where you plug in earphones),and play and enjoy your music.

If it does not play with aux try tunner, or video, one mustplay,and if it does ot play any, that means either the port of your laptop or the denon 700aedab port is faulty.

And don't forget to connect the speaker,because diffidently you will sure hear absolutely nothing with out the speaker.

Feel free to pass your comment .

Thanks for using fixya.

NAD C320 system sounds like a cheap, tinny tranny

Let's distill this down to its simplist configuration. FM source, stereo.

BTW, a search for NAD 440 only brings up a C440 >>>Tuner<<, no receivers. Are you sure about that model number? The only receiver model numbers with x40 on the NAD website are the C340 and C740, neither of which has a link to a manual (go figure). I have the C740 manual, so I'll use it for a loose reference.

If it still does what you're describing in a basic configuration and the volume control seems to affect it like you belatedly mentioned, I'd suspect a noisy volume control or some other control in the receiver (like a rarely used Tape Monitor switch) that is always there in the circuit but may have oxidized contacts and responds sometimes to burn-through.

Set the volume at a medium setting and repeatedly operate every switch, knob and button (one at a time) to gauge its effects on the sound. You may find one is the culprit. Then it's a matter of accessing it for a shot of contact cleaner.

If you have jumpers between Pre Out and Main In, it might be a good idea to reseat them, too.

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
