SPEAKERS
Four switches select which of the four speaker outputs A , B, C or SUB are heard
(see ).
Each switch can be operated individually or simultaneously and in any combination
and is perfect for performing A/B comparisons between various monitor setups. As
the switches do not toggle between outputs when doing A/B comparisons both of
those switches should be pressed at the same time i.e. to compare speakers A
and C, with A active press both the A and C switches to swap the output to C active,
and then again to return to the previous setting - this method can be used between
all four outputs if required.
An additional benefit is derived when using a sub-bass. If the sub-bass is attached
to the SUB/MONO output on the rear of the MC3.1, outputs A and B could deliver the
higher frequencies and allow for A/B (or in this case A+Sub/B+Sub) comparisons
between the two monitor setups by pressing the A and B switches simultaneously
and leaving SUB always active. In addition, a full frequency range monitor could be
attached to C, so, with the C switch active SUB should be disengaged.
Note that each speaker output has individual level trimming on the base of the unit
so that precise monitor level matching can be achieved - see sections and also
the ‘Monitor Calibration’ section.
MASTER VOLUME
The Monitor Volume control adjusts the signal level of both stereo channels for all
speaker outputs. The Volume knob affects the volume of the monitors A,B,C and
SUB only and does not have a bearing on any other output such as the headphones
or talkback jack.
A secondary preset volume control on the front edge provides a repeatable calibrated
output level for the monitors, so that at the press of the switch just below the main
volume knob the engineer can hear the mix at the same predetermined volume,
time after time, without having to meticulously adjust controls. Once the system is
calibrated (see Monitor
Calibration chapter)
the predetermined
level could be set via a
screwdriver to the
maximum listening
level, 85dB in the case
of TV, film and music,
for example, or to a
standard listening
level for radio, or even
a preffered level for
quiet passage. The
level chosen is at the
discretion of the
operator.
