Question about NAD C320 2-Channel Amplifier

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.

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.

How to hook up a vintage Marantz receiver to a Klipsch sub woofer with no sub outputs on receiver. I do have main in L and R Pre out L and R On the back of receiver. They use RCA jacks. The sub has L and...

The subwoofer is much more than just another bass unit and the purpose is to reproduce sub-audible content in order to add ambience to the listening experience and before it can reproduce the sound it must first be part of the recording or performance. Even if a recording is rich in sub-audible content, unless the amplifier is designed to process and filter sub-audible frequencies, the amount of content available at the output is likely to be minimal.

A pair of good 3-way loudspeakers will, most of the time produce a purer and more realistic sound with plenty of power and render a subwoofer superfluous.

The fact your amp doesn't have an output for a sub means, even if you successfully connect it there is unlikely to be much activity from it.
The only sensible way to connect it would be as a ghost speaker as used by many hi-fi enthusiasts since the introduction of stereo.

The purpose of a ghost speaker is to fill a gap between the channels and is driven by the difference in emf between the loudspeaker positive of each channel. Unfortunately the difference between the channels isn't great enough to drive a loudspeaker so another amplifier will be needed.
As it is a surplus subwoofer you are trying to find a use for you should either obtain the signal from the bass unit of each speaker or use a crossover type filter in the output of the second amp.

How do I connect my NAD cd-player?

If you have a receiver with a digital rca input, buy a good quality coaxial cable and connect it from the digital output of you cd or dvd player. The digital/analogue converters inside the receiver are almost always better than the ones in the cd player. If running cd to a stereo receiver, just use a good quality pair of rca interconnect cables. Red is right, White is left.

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.

Connect imac to amplifier

e4228d3d-a132-463b-8916-f7c5307ccb67.jpgI have looked at an image of NAD rear and it has RCA type jacks. I would plug it into the AUX sockets. Now to if it will work. Plug some stereo headphones into the iMac socket. If you can hear sound then the cable you intend to buy will transfer the sound you hear to the amp. If you want to record from the amp to your computer you will need another a different input on your computer and that would need to be connected to tape 1/2 out.
Any 3.5mm socket to RCA will do, they are not expensive plenty of cheap ones on Amazon and E-Bay (image shown). You will need two if you do want to record as well.

NAD C740 Chanel B Speakers not working The speaker output A is working properly, then the output B is completely silent. I install differents speakers and even the same speakers. no sound from the B...

possibly the causes are: 1. defective channel B power amp board. But try operating first with the built in tuner, if it's ok the RCA cable from your other sources(DVD player, etc...) might have broken internal conductor.
2. if it has the speaker switch(A, B, A+B) try toggling it, might also just loose contacts.
if the trouble is #1, leave everything to your trusted qualified technician, he knows what to do, unless you want to tweak/repair it by yourself...hope this helps ;-)

How do i hook up polk audio speakers to the imac when the speakers have ablack and red hookup and the computer has a single hole for audio?

Your speakers need amplification. Otherwise you will not be able to hear anything, even at full volume. Once you have an amplifier, you can buy a 1/8 inch stereo plug to RCA cable (1/8" to RCA) from the computer to the amplifier. You'd then use regular speaker wire between the amp & the speakers.

DOWNLOADED MUSIC ON PC

Sure you can. Download the songs in MP3 format (check here how to download music) and then double click the downloaded file. One of Bill's wonderful programs will open and play the song on the loudspeakers of your PC. I suppose you have connected some to the output jack of your soundcard. If you don't like the sound of your speakers, you can connect the PC to your stereo by using an adapter cable from audio jack 3.5 mm to 2xRCA.

Hope that helps
