Chapter 4 Operation Section
The status of this VU meter is determined by the selection of the Solo/
Efx Meter Switch. When the Solo/Efx Meter Switch is in the normal
position (up) the VU indicates the overall stereo mix of the Model SSM
until any solo or PFL switch is depressed. When any solo or PFL switch
is depressed, this VU meter displays that respective signal. When the
Solo/Efx Select Switch is depressed, this VU meter displays the sum of
all effects send signals.
This switch determines the source for the Solo/Efx VU display. In the
normal position (up) the VU displays any solo or PFL signal; when this
switch is depressed, it displays the sum of the effects sends.
Depressing this switch will insert a stereo volume pedal (connected at
rear) into the master signal path allowing dynamic control of the entire
mix. Level changes made by the volume pedal will be reflected in the
program, monitor and headphone outputs.
We strongly recommend the use of a passive volume pedal as opposed
to an active (powered) device. The reason for this is that the SSM's
expression pedal circuit is optimized for a passive pedal which will
always afford far better sonic results than its active counterparts.
Remember, the moment you insert a powered pedal at this point, you are
subjecting your entire mix to its frequency response limitations,
inherently greater distortion, higher noise, and significantly lower head
room.
This pot acts as the master volume to the balanced and unbalanced
stereo program feed. It should be pointed out that any adjustment to the
Program Master Control will be displayed by the left and right VU
meters.
With the Program Meter Sensitivity Switch (see rear panel) set to its
+4dbm position, a typical starting point for the program master is the
three o'clock position. This setting should make it reasonably easy to
achieve a 0VU reading when using multiple synth and sampler patches
without having to rely on excessive input trim (see input channel)
adjustments. If, however, a 0VU reading is desired when using only one
source (a single synth), it is perfectly acceptable to set the Program
Master Control higher that the three o'clock position to obtain the
necessary output.
The Program Master Control does not affect the monitor level or
headphone level.
