Question about NAD C320 2-Channel Amplifier

2 Answers

Long start up time, input selection remains on CD

My C320 takes about an hour until the red light turns green. Also, when I change input selection, eg from CD to AUX, the green light for AUX lights on but the sound input remains from CD. If all components are connected and switched on, the output level becomes slightly lower than if only one component is connected (and switched on). Is it the power supply/output stage, the input selector chip, or both?
Thanks

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.

My NAD C320 outputs a very low sound volume


Hi there I have a C340 that has similar problem, you must have bought this from ebay, lol.

Nad made a mistake on the C range, the pre - power link can be shorted out. if the pre is shorted out it takes out the pre amplifier stage, I have managed to get the right channel working, I will keep you informed what is the cause of the left channel. I have replaced the pre-amp IC and a couple of Jfets and transistors. Once I have repaired the Amp I could repaire yours if you like???

How do I connect my CD Player, Tape Deck and Tuner to the SU 300 Technics Amplifier


hi,
For connecting these to your amplifier you need 4 Stereo RCA Cable.
1.Connection for cd:
Take one of the RCA cable connect the one end (red/white) jack to the line out of your cd and connect the other end (red/white) to the CD input of Your amplifier.
2. Connecting the tunner:
Take one of the RCA cable and connect the one end (red/white) jack to the line output of you Tuner and connect the other end (red/white) to the TUNER input of your amplifier.
3. Connectiong the tape deck:
Now you have two RCA cable. Take one of the RCA cable and connect the one end (red/white) jacks to the PLAY out of the Tape deck and connect the other end (red/white) to the TAPE 1 play input of your amplifier.
Now connect the last RCA cable. Connect the one end (red/white) jack to the record input of the TAPE deck And connect the other end (red/white) to the TAPE 1 Record input of your amplifier.(this connection will help you to record to tape from cd or tuner. if you are not interested in recording then you can avoid this connection.)

Now you can select these three items from the frond plannel control switch of the amplifier.
ok

I have plugged my new HCHKAW08 into my PC, but I am getting no sound at all? Any help would be really well received.


As it is a 5.1 Speaker set, I assume there are lots of inputs to choose from. (like AUX, CD, DVD-player whatev). They are most likely RCA plugs (red and white)

- Check that the set is actually powered on. Some sets will have a red light for standby, and green for power-on. you might think it's on while it's only standby

- Select source. If the set has multiple inputs, you have to select one of them. If you plug your PC to AUX, select AUX on the front panel, or there will be no sound at all.

- Check the cable. Cheap RCA cables tend to die.

hope that helps.

Nad C320 right channel stops working then comes back again


This sounds like the "pre-amp" section is cutting out or there is some interruption in the signal path. A few things to try:

1) With the unit off, try "working" the volume,balance and tone controls. This means, turn them up and down a number of times to clear any debris that may be in the controls themselves.

2) Work the input selector switch the same way if it is a rotary switch.

3) Try turning on/off the tape monitor switch a few times.

4) Keep track of whether this problem is sensitive to heat. Does teh channel shut down more quickly once the unit has been on for a while?

Lastly, if you can solder, look for any solder joint that appears grainy or has rings and resolder it.

Update this with your results and we'll continue on...

Thanks,
Dan
