Q. GRAPHIC EQ - This 10 band graphic equalizer
consists of active band pass / band reject filters
spaced at octave intervals. Moving the sliders up or
down boosts or cuts the gain at the indicated
frequency. The EQ Trim slider provides an increase
or decrease of the bass’ signal through the graphic
EQ. When the slider is at its centered notched
position, the input signal is neither boosted or cut.
R. GRAPHIC EQ LED - This LED illuminates when
the Graphic EQ is active.
S. LOW COMP - This knob adjusts the compression
ratio below 400Hz. Rotating the knob clockwise
increases the compression ratio.
T. COMP - This push button switch is used to
activate the on-board compressors. When this push
button is in, compressors are active. Using the
footswitch overrides the front panel channel select
switch.
U. HIGH COMP - This knob adjusts the compression
ratio above 400Hz. Rotating the knob clockwise
increases the compression ratio.
V. COMP LED - This LED illuminates when the
compression circuitry is active.
W. COMP EQ BAL - This detented knob mixes the
low and high compressor outputs. When the knob is
at “1”, only the low compressor is in the output mix.
When the knob is at “10”, the high compressor is in
the output mix. By rotating the knob, an optimum mix
of both compressors can be obtained.
X. INPUT LEVEL LED - This LED illuminates GREEN
once the threshold of the compressor has been
reached. When a RED light is displayed, this
indicates clipping and your 300T is being overdriven.
When the compression circuitry is not engaged, the
LED will still indicate signal level.
Y. COMP GAIN TRIM - This knob adds gain to make up
for any level lost once the compression circuitry has
been engaged. Rotating the knob clockwise
increases the amount of gain.
Z. TUNER ONLY - This push button mutes all
outputs and sends your bass guitar's signal to your
tuning device (not included).
AA. MASTER VOLUME - This knob adjusts the
overall volume level of the 300T. Rotating the knob
clockwise increases volume with “1” producing no
volume and “10” producing maximum volume.
BB. POWER LED - This LED illuminates when the
300T is ON and receiving power.
CC. STANDBY - When the power switch and this
switch are ON, your Model T is ready to perform. In
the STANDBY position, power is supplied ONLY to
the tube filaments and sound will NOT come out of
the amp. Using the STANDBY SWITCH during short
breaks eliminates tube warm-up time and will
increase tube life.
