The Procedure:
1. Begin by turning off the monitoring system and ensuring that all inputs and
speakers are correctly connected.
2. Set all DAW/System controls to 0dB/unity gain - this should be left at this setting
from now on. Remove all e.q. and dynamics from the signal path.
3. If you have active speakers with their own level control, or speakers with an
amplifier, set all of these to maximum, so that they do not attenuate the signal.
4. On the underside of the MC3.1 you will find the speaker calibration trims - using
a screwdriver initially set all of them to their full attenuation position by rotating
each fully counter-clockwise. (See photo, opposite page).
5. With the Master Volume switch set the ‘Knob’ ( ) set the large volume on the
front of the MC3.1 to 12 0’clock and leave it there throughout the calibration procedure
- this will be the position that provides the 85dB listening level from now on.
6. Turn the system on and play the 500 Hz – 2.5 kHz bandwidth-limited pink noise
at -20 dBFS. Select the required Source on the front of the MC3.1 - I/P1, I/P2, I/P3,
AUX or DIGI. You should not hear it, yet.
7. Activate the A
Speaker by having only
the Speaker A switch
active in the speakers
section on the front
panel.
8. In order to hear only
the Left A speaker
remove the right
speaker by activating
the Right Cut switch.
9. On the underside of
the MC3.1 rotate the
Left A trim clockwise.
You will now start to
hear the signal, but
only for that speaker. Rotate until the SPL meter reads 85dB.
10. In order to hear only the Right A speaker switch in Left Cut and deactivate the
Right Cut.
11. On the underside of the MC3.1 rotate the Right A trim clockwise until the SPL
meter reads the desired level.
