NaD M15 model 2002

post #1 of 17
Thread Starter 

Hay all I have this NAD M15 but I have no idea how to use it.. my father who actually was working on it but he forgot how to use it..
So my question is very simple or silly kinda.. "how I can control the amp volume by the NAD?
post #2 of 17
The M15's manual is available for free on NAD's Web site: http://nadelectronics.com/products/masters-series/M15-Surround-Sound-Preamplifier#heading-downloads

The big knob at the right side of the pr/pro is its volume control knob. It changes the voltage output of the pre/pro's output connections. Those outputs need to be connected to external amplifiers. (That knob also can be used in combination with other buttons to change other parameters.)

It also sounds like you've lost its remote control, which includes a volume up/down rocker switch. You can order a replacement from NAD.

Ty very much thou smile.gif
What I have did now is I plugged my laptop to the 7.1 input and the amplifiers to the audio pre-out. It's working really good now but let's say that I want to put more speakers and I have 2 amplifiers for each one 4 inputs is it okay to plug 1 of the amplifiers to the Left speakers and the other to the right only?

PHwolfy,

Here is what you should connect your cables:
1. I presume you are using a stereo jack ( 3.5mm?) connected to your laptop audio out with RCA on the other end. Connect the RCAs
with an input at the back of NAD, say labelled Audio IN 1 or 2.
2. From the Audio OUT 1 of NAD connect RCA cables to the IN of your AMP.
3. In the INPUT selector switch it according to the connection you've made at the back (Audio IN 1 or 2)
4. As initial test. Set your laptop volume to 3/4 of power and your NAD will serve as your volume master.

One thing I noticed, you put your NAD on top of your AMP. Your NAD may enter protection if it gets too hot:eek:

Hope this helps.

Use the 7.1 input only for sources like a blu-ray payer with analog output. See above suggestion:)

Just switch the input corresponding to your source Ex. CD player >IN/ Audio 2, TV IN > Audio 3,...

Okay if let's say I want to watch a movie by the DVD. I should connect the DvD to the nad in the DvD input and then connect the amplifiers to the output. But in that case I can't control the volume by the NAD no matter what I'm doing the volume is controlled by the DvD or the amplifiers.

Ty it was very helpful! smile.gif but the problem still the same I can't control the volume by NAD either by the laptop or the AMP.
About what you noticed I am not putting it there for long time it's only for 10 mins I am actually trying to connect it perfectly then I will put it on its place. It's Temporary smile.gif

Make sure you selected the proper input (source) in your NAD.

On the NAD I should choose the DvD source right? I can hear the sounds and the voices but the volume controlled by the DVD and the AMP. That's my problem the volume control

The NAD volume control should work. Volume is not supposed to be controlled by the DVD player or by the amplifiers. A DVD player provides a standard audio output level which varies depending only on the relative sound levels in a movie DVD or music CD. (With a computer, you should set its audio output to a fixed amplification level. 100% usually is appropriate.) The amps are intended to provide a fixed amount of amplification for the signals coming from the preamp. The volume control knob (or up/down button on the remote) specifies how much the audio signal from the DVD player is attenuated or amplified within the preamp.

The first thing you need to do is reset the NAD to factory settings. That way you know exactly what you're working with. There's no way to know what configuration your father might have been using. See pages 17 and 20 of the Owner's Manual.

Please provide the exact model numbers of your DVD player, of your computer and its audio/video player software, and of your amplifiers so more detailed help can be provided.

That reset the remote control not the NAD. Aand details yaa.
The DVD is panasonic DMP-BD60 blue-ray I will post a pic too.
So I connected the DvD to nad inputs (L,R,video) in this case I will have 3 outputs and it's the video,r,l puts so everything in it place! The volume on the NAD is mute and the AMP is like 22- I still can hear the music.. the nad now take the sounds from the DvD to the amp that's all without controlling it.

Here is the way I plugged the DvD. The red RCA cable in the video output smile.gif my other cable is not working. Just saying so you don't get confused by my works! XD

Just to make sure: are your amplifiers connected to the connectors that are just above and to the left of the power connector? The ones in the section labelled "Audio Pre Out"?

If they're connected to the "MS OUT" connectors, that might explain the problem.


Otherwise, I'm at a loss and have to suggest that you contact NAD. There might be something electrically wrong.

For now I connected it in the DvD audio output
But when I put them in the pre out audio plugs I won't be able to hear a thing.
But if I connected the DvD to the 7.1 inputs it's work 100% perfectly.
I already contact NAD and I am waiting for responding smile.gif. Ty very much for helping. I got some new information smile.gif
