INTRODUCTION

getting Started

QUICK START

In case you simply cannot wait to experience the performance of your new 
NAD M2 Direct Digital Amplifier, we provide the following QUICKSTART 
instructions to get you underway.

Please make all the connections to your M2 with the unit unplugged 
from the AC outlet. 

It is also advisable to power-down or unplug all 

associated components while making or breaking any signal or AC power 
connections.

Connect your speakers to the LEFT and RIGHT speaker terminals and 
input sources to the applicable M2 rear panel input sockets.

WARNING 

 

The M2 employs a “floating” ground design. External devices (such as 
speaker switching or headphone adaptors) that connect the left and 
right channels together must not be used with the M2. Left and right 
channels must never be connected to each other.

Make sure that the OFF/AUTO trigger switch at the M2 rear panel is set 
to OFF.  Connect the AC cord to M2’s AC Mains input and then plug into 
an AC outlet. 

WARNING 

 

For optimal performance, the M2 requires a grounded AC receptacle or a 
separate earth ground. Ensure the proper grounding of your system.

Set the rear panel POWER switch to the “ON” position.  The Standby LED 
will illuminate amber (standby mode).

Press the front panel STANDBY button to turn ON the M2. The Standby 
LED indicator will turn from amber to blue and illuminate the VFD.

Press the corresponding front panel input button of your preferred 
source input.

SAVE THE PACKAGING

Please save the box and all of the packaging in which your M2 arrived. 
Should you move or otherwise need to transport your M2, this is by far the 
safest container in which to do so. We’ve seen too many otherwise perfect 
components damaged in transit for lack of a proper shipping carton, so 
please: Save that box!

NOTES ON INSTALLATION

Your NAD M2 should be placed on a firm, level surface. Avoid placing the 
unit in direct sunlight or near sources of heat and damp. Allow adequate 
ventilation. Do not place the unit on a soft surface like a carpet. Do not 
place it in an enclosed position such a bookcase or cabinet that may 
impede the air-flow through the ventilation slots. Make sure the unit is 
switched off before making any connections.

Use high quality leads and sockets for optimum performance and reliability. 
Ensure that leads and sockets are not damaged in any way and all sockets 
are firmly pushed home. For best performance, use quality speaker leads of 
16 gauge (1.5mm) thickness or more. 

Should water get into your NAD M2, shut off the power to the unit and 
remove the plug from the AC socket. Have the unit inspected by a qualified 
service technician before attempting to use it again.

do not remove the cover; there are no uSer-Serviceable
