To calibrate each speaker repeat steps 7 to 11 - replacing the speaker on step
7 for each set. For surround control use the switches in the
Surround Control
(2)
to
Cut/Solo the various speakers.
13.
To calibrate the sub - play the 40-80Hz signal, but this time have only the SUB
switch active - Left and Right Cut need not be active as the frequency of the signal
is limited to only the sub.
14.
On the underside of the MC7.1 increase the Mono trim increasing the volume of
the sub until the desired SPL meter reading is reached.
15.
Repeat steps 7 to 12 whilst playing
the full bandwidth pink noise and
adjusting to suit. The readings should be
pretty close and only require fine
adjustment.
16. Now the system is calibrated it is time
to set the
PRESET
volume control. Set the
Master Volume switch to ‘PRESET’ ( )
and with only one set of speakers active
in the Speaker Select switches ( ) adjust
the preset level on the front of the MC7.1
using a screwdriver until the SPL meter reads your desired listening level.
16.
You are finished and the calibration process has been completed.
The volume control will have a few dB’s of headroom so care must be taken to both
your hearing and system when increasing the volume passed the 12 o’clock
position. As with all things that are calibrated it’s a good idea to regularly check the
calibration of your monitors to ensure that nothing has changed.
