1 1 MC2.1 - Monitor Controller
The MC2.1 Controls
SOURCE
Three switches select which of I/P1 , I/P2 and AUX is heard (see ). Each can be
operated individually or simultaneously and in any combination. W hen operated
simultaneously the individual signals are summed into a single stereo signal.
Note that the MC2.1 does not provide individual level trims for the inputs and so any
level matching should be applied before it reaches the MC2.1.
SPEAKERS
Three switches select which of the three speaker outputs A (plus additional mono
output) , B or C 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 three outputs if required.
An additional benefit is derived when using a sub-bass. If the sub-bass is attached
to output A, delivering the lower frequencies, outputs B and C could deliver the
higher frequencies and allow for A/B (or in this case B+Sub/C+Sub) comparisons
between the two monitor setups by pressing the B and C switches simultaneously
and leaving A always active.
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.
MIX CHECKING
The mix checking section comes under two headings, Cut and Output , and when
used in conjunction with each other is a very thorough and versatile checking tool.
Under the Output heading three switches have been incorporated providing
Phase
Reverse, Mono and Dim .
Phase Reverse : Inverts the polarity of the signal on the Left Channel and is used
primarily to outline any phase problems that may be occurring in the mix/recording
such as phase cancellation, or an unbalanced stereo signal. As the switch is
toggled any phase issues will become more apparent and easier to identify.
Mono : With the switch active both Left and Right stereo signals are combined into
a single mono signal.
It is necessary when testing the audio to not only listen to the signal in stereo but
also in mono. It helps to outline problems in the mix, but also when testing for use
on non-standard applications such as for broadcast or mobile phone.
Dim : With the switch active the output level is attenuated by 20dB’s. It enables you
to lower the volume without adjusting any of the settings.
