6. mode:

The mode selector function is a convenient way to test the set up of the M3. For

example, use the Mono mode to check the speakers phase. Setting the mode to Left or
Right allows one to easily balance left signal inputs with right signal inputs.

Press the mode button to toggle through the four listening modes. A press longer than
one second will advance the mode selection to the next state as follows; STEREO, MONO,
LEFT, RIGHT, and then return to the STEREO listening mode. Release the mode button to
stop the sequence.

7. balance:

Adjust LEFT and RIGHT balance simultaneously using the volume (set up) control.

Both LEFT and RIGHT levels are adjustable b/- 9.5 dB
To adjust balance; press the balance button once and then within 5 seconds, rotate the
volume (set up) control to adjust the either the LEFT or RIGHT balance level. After about
5 seconds, the balance menu will switch off saving the balance settings in memory.

8. tone:

Press the

tone

button to activate or deactivate the tone controls. A press longer

than one second will toggle the tone option between TONE ACTIVE and TONE DEFEAT. To
bypass bass, treble, and spectral tilt controls completely, select TONE DEFEAT (direct bypass
of all analogue filters). To enable TONE ACTIVE, toggle the

tone

button to display TONE

ACTIVE and then release the

tone

button. Then within a few moments the tone controls

will display. Then press the

tone

button to toggle through bass, treble and tilt functions.

Selecting TONE ACTIVE allows one to adjust the bass, treble, and spectral tilt settings of
the M3 via the volume (set up) control. Bass and treble levels are adjustable b/-
5dB. The spectral tilt adjustment allows for simult/-3dB bass and treble offsets.
When adjusting bass and treble levels, the spectral tilt value will remain 0dB. When
adjusting the spectral tilt, the bass and treble values will follow the spectral tilt adjustment
simultaneously. See figures 6 & 7, examples of bass, treble, and tilt frequency response
diagrams.

9. biamp (crossover frequency selection):

If one uses smaller shelf-type speakers, in

conjunction with a powered subwoofer (refer to

PRE OUT 2

section under Rear Panel

Connections and Controls), the M3 allows the configuration of the speaker crossover
frequency to match the bass response of the speakers. Press the

biamp

button to toggle

through the filter sequence. A press longer than one second will advance the crossover
frequency selection as follows; BIAMP CROSSOVER FULL RANGE, HIGH PASS 40 Hz, HIGH
PASS 60 Hz, HIGH PASS 80 Hz, HIGH PASS 100 Hz, and then return to FULL RANGE.
Release the

biamp

button to stop the sequence. See figure 8 examples of the crossover

frequency response diagram. For connection of a subwoofer see Rear Panel Connections
and Controls;

10. speakers:

The M3 has two sets of speaker terminals A and B. One may switch on or off

both sets together or separately. Press the

button to toggle through the four

speaker selections. A press longer than one second will advance the speaker selection as
follows; SPEAKERS A, SPEAKERS B, SPEAKERS A+B, SPEAKERS Off, and then return to the
SPEAKER A selection. Release the speakers button to stop the sequence. Refer to biamp
for setting up the crossover frequency above.

11. volume (set up):

control for; volume control, balance

adjustment, tone controls, and renaming inputs. The default turn-on volume level setting
for the volume is -20 dB. The turn on volume level will always revert to -20 dB if the
volume level is set to greater than -19 dB before switching to standby.
