oscillator audio to the given output. Switch number 9 is used to send the
reference tone to the Main Left and Right Outputs.
External Slate Microphone
If you prefer to use an external slate microphone rather that the internal slate
microphone, you must simply plug an appropriate microphone into the external
slate microphone 3.5mm connector located on the right side, front edge of the
mixer near the mixer’s headphone jack. These two jacks were purposely placed
next to each other to allow the use of headsets with built in microphone booms.
The external slate microphone input jack contains switch contacts that
automatically switch over from internal slate microphone to external as soon as
you plug in the external microphone. The external slate microphone jack is wired
for use with nearly any tow wire, positive bias electret microphone. The tip is
used for both audio and microphone bias voltage. The ring connection is not
used and the case or shield connection provides ground.
Slate Microphone Gain
The slate microphone gain can be adjusted by using a small (Greenie)
screwdriver. The adjustment trim pot is located just to right of the slate
microphone switch. It is labeled as “SM ADJ”. Turning the trim pot clockwise
will raise the slate microphone level. Turning the trim pot counter-clockwise will
lower the slate microphone level.
Private Line
The Solice Mini mixer is equipped with a private line function which allows the
mixer operator to speak to the boom operator at will. When this momentary
switch is pressed, the slate microphone is routed to the auxiliary output which is
generally used to feed a signal to the boom operator. Thus, the mixer can talk to
the boom operator.
Tape Returns
The Mixer’s headphone monitoring section allows the use of tape returns. These
“Tape Return Audio Inputs” are contained on the TB3M “Returns” connector on
the rear panel of the Solice Mini mixer. There are two tape returns “Left” and
“Right”. These tape returns allow the operator to monitor “Tape” confidence (an
old, outdated, but still used term for recording verification) to insure that audio is
actually being recorded. Some recorders offer this recording confidence as an
output which can be connected to the Solice Mini mixer’s return inputs. When
