Front Panel Controls

INPUT:

1. Input:

A standard ¼" input jack to plug in active or pas-

sive basses using a shielded cord.

2. -10dB PAD:

Input attenuator button. The button is generally

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.

Clip LED:

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.

Tuning Mute Button:

Set this switch to "ON" (In) when tuning up. This

switch mutes all outputs from the amplifier (speak-

er, 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.

Mute LED:

LED turns on when "Tuning Mute" is switched to

the "ON" position or when activated through the

footswitch.

Channel A/B:

Switches between the Normal and Overdrive chan-

nels. When in the "B" (In) position, the switch

activates "Channel B" (Overdrive). "A" (Out)

position activates "Channel A" (Clean). In or-

der to use the footswitch to control the channel

switching,"Channel A/B" should be in the "A"

(Out) position on the 2001RB.

2001RB & 2001RBP

CHANNEL B:

Channel B LED:

LED turns on when in the "Channel B" (Overdrive)

mode.

3. Gain:

Controls the amount of overdrive in the "B" chan-

nel. At low settings it provides a smooth distorted

sound. At high levels it will provide full saturation

with long sustain.

4. Edge:

Treble control for the Overdrive channel.

5. Bottom:

Bass control for the Overdrive channel.

6. Level-B:

Adjusts the output level of the Overdrive channel.

CHANNEL A:

Channel A LED:

LED turns on when in the "Channel A"

(Clean)mode.

7. Level-A:

Sets preamp gain after the input stage. It is used

in conjunction with the input pad, to optimize the

amplifier's headroom.

VOICING FILTERS:

8. 4/5 String Bass:

Switching this button to the "ON' position, voices

the pre-amp for basses with "B" tuning (5 string

bass). Leaving it in the "OUT" position will voice

the amp like the 800RB, for a four string bass.

9. Contour:

Drops the mid-range frequencies while boosting

lows & highs.

10. Presence:

This adds edge and definition to higher frequen-

cies.
