I N P U T:
1 . I n p u t :
A standard ¼" input jack to plug in active or
passive basses using a shielded cord.
2 . - 1 0 d B P A D :
Input attenuator button. The button is gener-
ally left out, except in rare cases when the clip
LED flashes. This switch should be pressed if
the CLIP LED stays on continuosly. It may be
necessary to "pad" the input if you are using a
bass with active electronics or very high output.
C l i p L E D :
LED lights yellow when the input stage is being
over-driven. If -10dB PAD (2) is pressed and
clip LED still stays lit, turn down the volume on
your bass.
Tu n i n g M u t e B u t t o n :
Set this switch to "ON" (In) when tuning up.
This switch mutes all outputs from the ampli-
fier (speaker, direct, and balanced outs) so you
can tune up without sending signal to the
audience, speakers, or the P.A. system. Tuning
Mute can be footswitch controlled by using the
GK "RFB-III" footswitch, which will leave both
hands free to tune your instrument. To control
Tuning Mute by footswitch, the "Tuning Mute"
switch on the 2001RB must be in the "OFF"
(OUT) position.
M u t e
L E D :
LED turns on when "Tuning Mute" is switched
to the "ON" position or when activated through
the footswitch.
C h a n n e l
A / B :
Switches between the Normal and Overdrive
channels. When in the "B" (In) position, the
switch activates "Channel B" (Overdrive). "A"
(Out) position activates "Channel A" (Clean).
In order to use the footswitch to control the
channel switching,"Channel A/B" should be in
the "A" (Out) position on the 2001RB.
