Speakers Located on the rear panel are two sets of speaker jacks. [. . . ] Maintenance Your new amplifier is rugged. It was built to give you a lifetime of trouble-free operation. If it is operated in accordance with the instructions above, your only maintenance problems should be cleaning. We recommend a soft damp cloth and mild soap for cleaning the outside surfaces. If you are going to pack your amplifier around a lot, we recommend a road case to protect it from scratches and road wear. Road bags are available from Gallien-Krueger. Setting Up Your Sound Your amplifier is designed to sound about right with the tone controls set flat (at"5"). We therefore recommend you start with the EQ set flat, the voicing filters out, and the crossover at 500hz ("5"). Don't be afraid to experiment with the EQ on your bass first. Make sure that you have as close to the sound you want from your Bass before adjusting the EQ on your amp. You may want to push up your volume and boost levels while dropping back the masters. This will give a fatter sound but can add distortion. Some players find this desirable, you will have to be the judge. For the cleanest possible sound, operate the masters near or on "10" (max). The boost control is footswitchable and can act as a preset volume. The LED next to the boost control indicates that boost is on. You may have to experiment with the crossover point and the relative levels of the high and low masters. It is best to adjust them before the EQ. They should be adjusted to give the most desirable sound without distorting the high end speakers. [. . . ] Basically, this band effects the body of your sound. Effects only the bottom end and will be used to account for varying room acoustics.
