1. 0dB Input accepts a standard 1/4” instrument

plug from your bass. This input is suited for use

with instruments that have passive electronics.

2. -15dB Input accepts a standard 1/4” instru-

ment plug from high output basses. This input is

padded 15dB to compensate for higher output

sources and is suited for use with basses that

have active electronics or high output pickups.

3. Ultra Low increases the low frequency output

by 7dB at 40Hz. This adds to the rumble and

overall feel of the low bass notes.

4. Ultra Mid decreases the mid frequency out-

put by 6dB at 600Hz. This removes some of the

middle frequencies for a “contoured” sound.

5. Ultra High increases the high frequency out-

put by 7dB at 5kHz. This adds crispness to your

sound.

6. Peak LED illuminates when the Gain control

(#8) is set too high. This indicates overdriving of

the preamplifier which causes clipping. (See the

Gain control, #8.)

7. Signal LED illuminates when the Gain control

(#8) is adjusted properly. (See the text for the

Gain control.)

8. Gain must be adjusted to match the output of

your instrument to the amplifier. For the proper

setting, turn on the amplifier, rotate the Gain

control and the Master control (#13) fully count-

er clockwise and begin playing your bass.

Rotate the Gain control clockwise until the

Signal LED (#7) illuminates while playing and

the Peak LED (#6) flashes occasionally.

9. Bass adjusts the output level of the low fre-

quencies and offers a cut or boost of 12dB at

70Hz.

10. Low Mid adjusts the output level of the lower

midrange frequencies and offers a cut or boost

of 12dB at 300Hz.

11. High Mid adjusts the output level of the

upper midrange frequencies and offers a cut or

boost of 11dB at 1.5kHz.

12. Treble adjusts the output level of the high

frequencies and offers a cut or boost of 14dB at

7kHz.
