WARNING
The front panel o (Standby) button is disabled as long as the male
plug of the mono cable (with or w12V DC) is connected to M23’s
+12V TRIGGER IN. Unplug the mono cable for the M23 to be powered up
from standby mode to operating mode and vice-versa using the front
panel
o (Standby) button.
6 GAIN LEVEL (LOW/MID/HIGH)
•
Gain level adjustment allows the source to be played back at the
same volume level so you don’t need to adjust the volume every
time you change to a new source.
•
The Gain Level of the M23 can be set to any of the following - LOW
(29dB), MEDIUM (24dB) and HIGH (19dB).
7 BRIDGE MODE
M23 can be configured to be MONO (ON/BRIDGE), more than doubling its
output power. This way, M23 can be used as part of a high power stereo or
home-theatre system, by connecting additional power amplifiers.
•
In BRIDGED MODE (switch at ON/BRIDGE setting), M23 will produce
approximately 700W into an 8 ohm loudspeaker. In this mode, the
amplifier sections will react as though the speaker impedance has
been halved. Low impedance speakers (under 8 ohms) are not
recommended when using Bridge Mode as these may cause the
amplifier’s thermal cut-out to operate if played at high levels.
•
Set the BRIDGE MODE switch to ON/BRIDGE position and connect
the speaker to the terminals marked “L +” and “R-” ensuring that the
“L+” is connected to the “+” terminal of your speaker and the “R-” is
connected to the speaker’s “ - ” terminal.
•
Connect the source to Left Audio Input ports only. Do not connect
anything to Right Audio Input ports when Bridge Mode is selected.
•
Set BRIDGE MODE switch to OFF/STEREO for normal operation.
8 LED LEVEL (DIMMER)
•
Press repeatedly to turn off or adjust the brightness level of the
Power indicator.
9 POWER
•
The AC mains power to M23 is regulated by the POWER switch. When
the POWER switch is set to ON position, M23 goes to standby mode as
shown by the amber status condition of the Power indicator. Press
o
(Standby) button to power up M23 from standby mode.
•
If you intend not to use the M23 for long periods of time (such as
when on vacation), switch off the POWER switch.
•
The o (Standby) button cannot activate M23 with the rear panel
POWER switched off.
10 AC MAINS INPUT
•
M23 comes supplied with a detachable power cord.
•
Ensure that the supplied power cord’s female connector end is
firmly secured to M23’s AC Mains input socket and the male plug
connected to the mains power source.
•
Always unplug first the power cord from the mains power source
before disconnecting the female connector end from M23’s AC
Mains input socket.
11 FUSE HOLDER
•
Only qualified NAD service technicians can have access to this fuse
holder. Opening this fuse holder may cause damage thus voiding
the warranty of your M23.
12 GROUND TERMINAL
•
Ensure M23 is plugged-in to a grounded AC wall outlet.
•
If a separate earth ground is necessary, use this terminal to ground
your M23.
•
M23 can be connected to ground by connecting a ground lead
wire or similar to this terminal. After insertion, tighten the terminal
to secure the lead.
