Sorted it. You have to put the plugs back in the PreampOUt/Main in or it cuts out the pre-amp.

Amplifier works great with CD player , but with turntable the sound is poor when volume at highest

Hi. Does the amplifier have a dedicated phono input and are you using it?

If not then you will need an amp that has or an external phono preamp.

What model is your amplifier?

Is an unidentified player compatible with an NAD integrated amp which has analog inputs?

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

What kind of pre amp do i need to operate my parasound HCA-2205A high current power amp

Any preamp should work. A preamp goes into your system between the amp and the other components which plug into it- CD player, FM tuner, Turntable.....etc. It's takes their output signal, processes it as my be Volume, bass, treble... and then send a sufficient signal to the amp to drive the amp to power your speakers. As long as the preamp output is enough for your Amps input any will work as most will be.

Sorry, new at this and finding the manual hard to understand, how do I connect my nad C-340 amp to my C-162 preamp. Trying to add a turntable and have a few other questions

You must connect the turntable to the plugs on the left side of your amplifier when you are behind the pre amp. You have to know if you are using a MC or a MM element in your turntable and connect to the right plugs. Don't forget to put the switch in the right position (also MC or MM) The moving coil element is giving a very low voltage accordingly to the Moving magnet element. So it needs some extra amplification.

Cant get no sound from my Nad C162 pre amp connected to my C272 power amp , and ideas please?

First prove if it's a preamp problem or an amp problem. Plug one of your sources directly into the amp for a moment and play something VERY LOW in volume. If the amp is ok it will play VERY LOUDLY.

If so, look at the preamp and make sure it's not muted or a tape is selected.

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.

Hav nad 2100. I dont understand what the lab in post are for?

From what I have found online, Lab-In was a NAD feature that restored the frequencies that were rolled off when turntables were being used.

"NAD belleived at the time that practical PHONO stages and the preamp and power amplifier stages be rolled off at subsonic frequencies to prevent subsonic wow and flutter from Turntables and supersonic frequencies (EMI/RF/Radio) signals from getting into the system in the first place. Their notion was that if your ears cannot physically hear it, then why amplify it. For the PURIST, there were a set of LAB IN amplifier inputs with more extended response called "LAB IN" inputs"

Use them UNLESS you have a turntable source.

Yamaha m70 amp and c70 pre-amp right speaker stopped working

First, lets's determine if it's the amp or the preamp...

Swap the Left and Right channel cables between preamp and the amp with each other.

Did it stay on the right? = amp problem.

Now on the left? Preamp or source.

Plug any Line Level device (CD?) directly into the amp inputs. Work now? Preamp problem.

ALL sources? Preamp - toggle all controls, especially a Tape Monitor to possibly wipe of any built-up oxides in them.
