1. INPUT: Use this 1/4” jack to connect your bass to the amplifier by means of a shielded instru-
ment cable.
2. 0dB/-15dB: Use this switch to match the output signal level of your instrument to the amplifier.
If your instrument has standard pickups, setting the switch to the 0dB position (switch in the out
position) should yield the best results. If your bass has active electronics or high output pickups,
set the switch to the -15dB position (switch depressed).
3. MUTE: This switch, when depressed, interrupts the signal prior to the power amplifier, allowing
you to tune your instrument in silence.
4. LEVEL: Use this control to adjust the output level of the Clean channel.
5. LOW: Use this control to adjust the low frequency output of the Clean channel.
6. LO MID: Use this control to adjust the lower-midrange frequency output of the Clean channel.
7. HIGH MID: Use this control to adjust the upper-midrange frequency output of the Clean chan-
nel.
8. HIGH: Use this control to adjust the high frequency output of the Clean channel.
9. EXPANDER: This switch, when depressed, activates the Expander circuit.
10. (LED): This LED illuminates when the Expander circuit is active.
11. –V–: Use this control to adjust the depth of the Expander circuit. As you rotate this control
counter clockwise the signal becomes increasingly crisper and cleaner; clockwise makes the sig-
nal more punchy.
12. LEVEL: Use this control to adjust the level of the Expander circuit. This allows you to have two
different playing levels - one with the Expander on, another with it off.
13. MASTER: Use this control to adjust the overall output level of the amplifier.
14. LIMIT LED: This LED illuminates when the internal limiting circuit is active. Occasional flash-
ing during playing is normal. If the Limit LED remains illuminated, reduce the output level of the
amplifier until the LED flashes.
15. : Use this jack to listen to the amplifier through a pair of stereo headphones. The internal
speaker is disconnected when the headphones jack is used. To avoid possible damage to
your hearing, do not use headphones for extended periods of time at extremely loud
listening levels.
