[. . . ] Avoid spraying insecticides near the unit. . · Maintenance: Your new amplifier is rugged. It was built to give you years of trouble-free operation, if it is operated in accordance with the instructions contained in this manual. If you are going to move your amplifier around frequently, we recommend a road case to protect it from scratches and road wear. . . · · · Moving the Unit: Before moving the unit, be certain to disconnect any interconnection cords with other components, and make sure that you disconnect the unit from the AC outlet. 12 2001RB & 2001RBP Front Panel Controls Front Panel Controls I N P U T: 1. Input: A standard ¼" input jack to plug in active or passive basses using a shielded cord. The button is generally left out, except in rare cases when the clip LED flashes. 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. 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 amplifier (speaker, direct, and balanced outs) so you can tune up without sending signal to the audience, speakers, or the P. A. 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. When in the "B" (In) position, the switch activates "Channel B" (Overdrive). In order to use the footswitch to control the channel switching, "Channel A/B" should be in the "A" (Out) position on the 2001RB. CHANNEL B: Channel B LED: LED turns on when in the "Channel B" (Overdrive) mode. CHANNEL A: Channel A LED: LED turns on when in the "Channel A" (Clean)mode. It is used in conjunction with the input pad, to optimize the amplifier's headroom. 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. Contour: Drops the mid-range frequencies while boosting lows & highs. [. . . ] As the amp works harder, the fan speed increases to keep everything cool. Voicing Filters: Voicing filters are used to completely re-voice the amplifier. In the case of the Contour and String Bass controls, the effect is dramatic. The Contour control tunes between two different shaping circuits, with greatly different response. With the control all the way up, the low end is slightly boosted, the mids are dropped and the high end is pushed up. [. . . ]
