FRONT PANEL CONTROLS (FIGURE 1)
1. Standby Button:
The Standby Button turns on and to standby the M3. This button will
only function when the Status Condition LED is either blue representing the on-state, or
amber representing the standby state.
2. Status Condition L.E.D.:
Standby:
When this L.E.D. is amber the M3 is in the standby state.
On:
When this L.E.D. is blue the M3 is operating in the on-state.
Protection:
When this L.E.D. is red the M3 is in a protection state.
The M3 has sensors for abnormally high internal heat and signal level conditions that
would damage either the M3 or speakers. When these conditions return to normal, the
M3 reverts to the on-state. In the event the Status Condition L.E.D. is red and PROTECT
displays in the VFD for longer than 5 minutes; switch off the M3 via the rear panel POWER
switch, check all speaker cables and connections for short-circuits. Resume normal
operation. If the Status Condition L.E.D. continues to light red and PROTECT displays in
the VFD, contact qualified NAD service personnel for repair.
3. Vacuum Florescent Display (VFD):
The VFD provides visual information on all of the
M3's important modes, settings, and functions for both main and second zone locations.
4. listen (input selection):
Press the listen button to select an input. A press longer than
one second will advance the input selection to the next input as follows; DISC, CD, TUNER,
INPUT 4, INPUT 5, INPUT 6, BALANCED and then return to DISC. Release the listen button
to stop the sequence.
Assigning User Names (input selection): Renaming inputs is advantageous when using
auxiliary equipment not representing the default inputs. For example, a CD-player with
balanced outputs would connect to the balanced input. Rename the balanced input to
CD-Player as follows;
Press and hold simultaneously the
listen
and
record / Z2
buttons until the cursor flashes.
Rotate the
volume (set up)
control to the letter "C" then press the
listen
button to lock
the selection and advance the cursor. Continue the procedure for the remaining letters of
the name. Press the
record / Z2
button to save the new user name.
NOTES:
There is a maximum of 20 letters to each name. The variables are; lowercase letters,
uppercase letters, numbers, and miscellaneous punctuation symbols.
Record each name you assign into the chart on page 17 to aid you for future reference in
the event you wish to change the hook-up and assignment of the inputs.
5. record / Z2 (second zone output):
Press the
record / Z2
button to select the input as
the recording source. A press longer than one second will advance the source selection to
the next input as follows; OFF, DISC, CD, TUNER, INPUT 4, INPUT 5, INPUT 6, BALANCED,
LOCAL, and then return to OFF. Release the
record / Z2
button to stop the sequence.
Furthermore, the ZR3 remote control will allow direct selection of inputs (see ZR3 Remote
Control).
NOTE:
The
record / Z2
can monitor all inputs. The
record / Z2
will maintain its last state even
if the M3 is set to standby. The M3 must be in its on state in order to use the record / Z2.
