9 +12V TRIGGER IN: This input allows the M2 to be switched remotely

to standby mode or ON by ancillary equipment, such as an amplier,

preamp, AV processor, etc. The controlling device must be equipped

with a 12 V trigger output to use this feature.

10 +12V TRIGGER OUT: The +12V TRIGGER OUT is used for controlling

external equipment that is equipped with a +12V trigger input. This

output will be 12V when the M2 is ON and 0V when the unit is either

OFF or in standby mode.

11 RIGHT SPEAKERS: Connect the right speaker to the terminals marked

“R +” and “R-” ensuring that the “R+” is connected to the “+” terminal

on your loudspeaker and the “R-” is connected to the loudspeaker’s “-”

terminal. There are two sets of RIGHT SPEAKER outputs and these are

identical in function (parallel connection) and are provided for ease of

Bi-wiring with heavy audiophile cables. Double check your speaker

connections before powering up the M2.

Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire

to connect loudspeakers to your M2. The high-current binding post

terminals can be used as a screw terminal for cables terminating in

spade or pin sockets or for cables with bare wire ends.

BI-WIRING

Most modern high quality loudspeakers oer the option of Bi-wiring.

This separates the HF crossover from the LF crossover and oers

enhanced performance by preventing LF return currents from aecting

the HF performance. If you decide to bi-wire, be sure to remove the

“links” at the loudspeaker that connect the LF and HF sections (these are

provided for convenience when single wire connection is used). Your

loudspeaker instruction manual should cover this subject as well.

WARNING

The M2 employs a “oating” 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.

12 POWER SWITCH: The POWER switch supplies the master AC mains

power for the M2. When this switch is at ON position, the M2 is in

standby mode as shown by the amber status condition of the standby

LED. Toggle the front panel’s STANDBY button to switch ON the M2 or

back to standby mode. If you intend not to use the M2 for long periods

of time (such as when on vacation), switch the POWER switch to the

OFF position. When the POWER switch is at OFF position, the front

panel STANDBY button or M2 remote control cannot activate the M2.

13 AC MAINS INPUT: The M2 comes supplied with a separate AC Mains

cable. Before connecting the cable to a live wall socket ensure that

it is rmly connected to the M2’s AC Mains input socket rst. Always

disconnect the AC Mains cable plug from the live wall socket rst,

before disconnecting the cable from the M2’s Mains input socket.

14 FUSE HOLDER: In the unlikely event a fuse may need to be replaced,

unplug the AC cord from the wall. Disconnect also the AC cord from

M2’s AC Mains input socket. Then, remove all connections from the

amplier. Use a athead screw or similar to open the fuse holder via the

slot located on the top edge of the fuse holder. With the screw driver

in place, push it outward to unlatch and open the fuse holder. Only

replace the fuse with the same type, size, and specication.

IMPORTANT NOTICE

Do not use any substitute fuses of dierent types, ratings or values.

Failure to observe this precaution may cause damage to the amplier

circuits and may create a re hazard and/or defeat the safety built into

the M2 thus voiding the warranty.

15 LEFT SPEAKERS: Connect the left speaker to the terminals marked “L

+” and “L-” ensuring that the “L+” is connected to the “+” terminal on your

loudspeaker and the “L-” is connected to the loudspeaker’s “-” terminal.

There are two sets of LEFT SPEAKER output and these are identical in

function (parallel connection) and are provided for ease of Bi-wiring

with heavy audiophile cables. Refer also to “RIGHT SPEAKERS” above.

16 RS-232: Connect this interface via RS-232 serial cable (not supplied)

to any Windows® compatible PC to allow remote control of the M2

through NAD’s proprietary PC software or other compatible external

controllers. NAD is a certied partner of AMX, Control4, Crestron and

Savant and fully supports these external devices. See your NAD audio

specialist for more information.

17 IR IN: This input is connected to the output of an IR (infrared) repeater

(Xantech or similar) or the IR output of another component to allow

control of M2 from a remote location.

18 GROUND TERMINAL: The M2 requires a grounded AC receptacle or a

separate earth ground. Use this terminal to properly ground your M2. A

ground lead wire or similar can be used to connect the M2 to ground

via this ground terminal. After insertion, tighten the terminal to secure

the lead.

BARE WIRES AND PIN CONNECTORS

Bare wires and pin connectors should be inserted into the hole in the shaft

of the terminal. Unscrew the terminal’s bushing until the hole in the screw

shaft is revealed. Insert the pin or bare cable end into the hole and secure

the cable by tightening down the terminal’s bushing. Avoid any danger

of bare metal from the cables touching the rear panel or another connector.

SPADE CONNECTORS

These should be slotted under the terminal’s screw bushing, which is then

fully tightened. Ensure the connector is tightly secured and there is no

danger of bare metal from spade connectors touching the rear panel or

another connector as this may cause damage.
