Operation Manual

5 POWER
• Supply the AC mains power to the M22.
• When the POWER switch is set to ON position, the M22 goes to
standby mode as shown by the amber status condition of the
Power indicator. Press o (Standby) button to switch ON the M22
from standby mode.
• If you intend not to use the M22 for long periods of time (such as
when on vacation), switch o the POWER switch.
• The o (Standby) button cannot activate the M22 with the rear
panel POWER switched o.
6 AC MAINS INPUT
• The M22 comes supplied with a detachable mains power cord.
Connect corresponding end of the mains power cord to the AC
mains input of M22 and the plug connected to a mains power
source.
• Always disconnect the mains power plug from the mains power
source rst, before disconnecting the cable from the M22’s AC
Mains input socket
7 FUSE HOLDER
• Only qualied NAD service technicians can have access to this fuse
holder. Opening this fuse holder may cause damage thus voiding
the warranty of your M22.
8 GROUND TERMINAL
• Use this terminal to properly ground your M22 to a grounded AC
receptacle or a separate earth ground.
• The M22 can be connected to ground by connecting a ground lead
wire or similar to this ground terminal. After insertion, tighten the
terminal to secure the lead.
NOTES
• The above illustration shows the M22 being connected to ground via
a metal water pipe. There maybe other grounding conductor points
in your home. Consult with a licensed electrician to properly locate
or correctly install a grounding conductor in your home. NAD is not
responsible for any malfunction, damage or costs associated with the
installation, connection or grounding of your M22.
• The grounding wire is not supplied with your M22.
9 +12V TRIGGER IN
• The +12V Trigger input allows the M22 to be switched remotely
from standby mode to ON and vice-versa by an ancillary equipment
such as a preamplier, AV processor, etc. The controlling device
must be equipped with a 12V trigger output to use this feature.
WARNING
The front panel o (Standby) button is disabled as long as the male plug
of the mono cable (with or without +12V DC) is connected to M22’s +12V
TRIGGER IN. Unplug the mono cable for the M22 to be normally switched
ON (or back to standby mode) using the front panel o (Standby) button.
10 LED LEVEL (DIMMER)
• Toggle to cycle through Power indicator brightness levels.
11 RIGHT SPEAKERS, LEFT SPEAKERS
• The M22 is equipped with gold-plated, color-coded, transparent
and special high-current binding-post speaker terminals.
• Connect RIGHT SPEAKERS and LEFT SPEAKERS terminals to
corresponding speakers. Make sure the “+” (red) terminal and “-”
(black) terminal are connected to the corresponding “+” and “-”
terminals of the speaker. Use extra care to ensure that no stray wires
or strands cross between posts or terminals at either end.
• The M22 is designed to produce optimum sound quality when
connected to speakers with impedances within its operating range.
Please make sure that all the speakers are rated 4 ohms minimum
per speaker.
NOTE
Use stranded wire of at least 16 gauge (AWG). Connections to the M22
can be made with banana plugs or by using bare wire or pins. Use the
transverse hole through the post for bare-wire or pin connections. By
loosening the terminal’s plastic nut, make a clean, neat connection and
re-tighten carefully. To minimize the danger of short-circuit, ensure that
only 1/2-inch of exposed wire or pin is employed when connecting.
DIGITAL POWERDRIVE
The M22 uses NAD
’
s proprietary Digital PowerDrive
™
amplier technology
that allows substantial additional power for short periods of time.
Research has shown that the peak to average power required to faithfully
reproduce music can be a factor of ten for well recorded performances.
Digital PowerDrive uniquely satises this requirement. Music sounds more
dynamic and “open” with PowerDrive because the musical transients
that are present in a live performance are not reduced in amplitude or
“compressed”.
