DRAWMER
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 MC2.1 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. Set the large volume on the front of the MC2.1 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 MC2.1 - I/P1, I/P2 or AUX.
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
Righ Cut switch.
9. On the underside of the MC2.1 rotate the Left A trim clock-wise. 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.
