If the Nad has pre-amp out sockets that are currently connected to the power amp in the receiver. Then you can sever those link and put the pre-amp out into your Aragon inputs. Otherwise I don't see how you can connect the amp.

I don't see why not. Just get the value of the pot off the numbers on the back of it or measure it

Check your speaker setup menu to make sure that zone 2 is enabled. Also, a lot of receivers only allow analog inputs to be used for zone 2, so if you are using something like hdmi, or optical than this might be the problem.

If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Search the site by type in the "brand name" to your device; (Exclude the model number), in the "Search box at the top right of the display window of the Homepage" to get gathered related posts

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.

It could be a pre amp or amplifier problem and would require either replacement or a service technician to look at it.

if you are reffering to a radio fm receiver, the issue is the signal strength is too low.so the multiplex transmission cannot be correctly unscrambled.mono reduces the cross channel interference. use a high gain 12 db or above external vhf antenna to solve this problem

Should be able to connect it to the chassis of the receiver.

Probably a fuse in the unit. Unplug it and open it. If you see a blown fuse, take it out and look at the writing on the metal part. buy a fuse with the same power ratings.

Engineers in Jburg? Sorry I've got no idea. I'm an engineer in SW London and repair amps etc from all over the country, if you can pack it very well and post it here I'll fix it for you. I'll give you a price gude first, what's the model and fault?
Dave.

Probable answer? Dirt..Sometimes you can get poor contacts working again by gently working the switches 50-60 times with the device off. If this procedure fails Use a good contact cleaner... HTH!

As long as the "player" has phono connections you should have no problems with compatibility.

If it's not happening when your speakers are disconnected, your problem is not in the receiver, it's either a wire touching at the terminals on the rear of the receiver, or a bad voice coil or crossover in your speaker. If you re connect the speakers and it immediately cuts out, disconnect all speakers and reconnect one by one testing the receiver each time until your receiver shuts off or remains on with all wires connected and you've fixed the problem. If it cuts out, disconnect the problem speaker at the speaker and test again. If it stays on, problem is in the speaker, if it still cuts out, problem is in the wire. Hope this helps. If you need further help, post a comment and I can help you troubleshoot some more.

Normaly this is what cause little volum and distortion. Check first if you got +68/-68V on amp module left and right Often the -68V is missing. This is caused by faulty transistor Q712 (2SA872) in +68/-68V power supply.

take it to the repair shop,, unless you're an electronics tech,,, if so, reply & i'll take you further
