C. STAGE OUTPUTS
Use the HIGH-level output to directly drive a power amplifier
(Crown, BGW, Phase Linear, etc.) and use the LOW-level output
to drive conventional musical instrument amps. If you need more or
less level and can’t correct the problem by adjustment, try the
other output.
D. PA OUTPUTS
Use the mic-level PA output to directly connect the SC-44 to a
studio or PA system mixing console microphone input, or use the
LINE-level output to drive a line input. The mic connection should
be used for long cable runs because it is a balanced line which
helps to minimize noise. (This mic-level output can be used with
any console mic input including balanced, unbalanced, and phantom
powered types.) A ground-lift switch is provided on the rear panel
to float pin 1 of the XLR connector to eliminate ground loops where
necessary.
V. OTHER HOOKUPS
With the multitude of inputs and outputs available on the SC-44
there are many possible variations in its use. A few are
presented here as an illustration. Experimentation will be neces­
sary to exactly meet individual needs.
1 . When not using the PA output as a direct feed, it may be
used to feed a second stage amplifier, with separate level
control.
When 'taking a line-level feed from another amplifier or
preamp, connect it into the EFFECT return rather than the
channel input thus bypassing the preamp and equalizer and
feeding the fader directly.
Smooth distortion may be produced by wiring (2) 1N914 diodes
paralleled in opposite directions between the tip and sleeve
of a phone plug and inserting it into the channel EFFECTS send
A foot switch can be wired in series with the tip of the plug
to switch out the distortion.
