BA Series Front Panel Features
1. INPUT: The signal output from an
instrument (active or passive) may
be connected to this 1/4" input by
means of a shielded instrument cable.
2. –15 dB: Press this switch in to
reduce the input signal by 15 dB
and compensate for higher output
sources. This attenuation is suited
for use with basses that have active
electronics or high-output pickups.
3. SCRAMBLER: Engage this switch to
activate the Bass Scrambler™ overdrive
circuit. This allows for varying amounts
of tube-like grind and distortion.
4. SCRAMBLER LED: This LED
illuminates green when the Bass
Scrambler™ overdrive is on.
5. DRIVE: Use this to adjust the amount
of Bass Scrambler™ overdrive effect.
Rotate the control clockwise for a more
overdriven sound, or counter-clockwise
for a less overdriven sound.
6. BLEND: Use this to blend the Bass
Scrambler™ affected signal with the
clean unaffected signal.
7. VOLUME: Use this to control the
overall output level. It affects the preamp
level to speaker and phone outputs. Use
it wisely, and turn it down when making
connections, putting on headphones, or
trying something new. It does not affect
the signal fed to the aux input.
8. ULTRA LO: This switch, when engaged,
enhances the amount of low-end
output by 1 dB at 40 Hz and –10 dB
cut at 500 Hz.
[BA-112, BA-115, BA-210]
9. ULTRA HI: This switch, when engaged,
enhances the amount of high frequency
output by 5 dB at 8 kHz.
[BA-112, BA-115, BA-210]
10. BASS: Use this to adjust the low
frequency level of the amplifier. The low
frequency output is flat at the center
position. See pages 10-14 for technical
specifications.
11. MID: Use this to adjust the midrange
frequency level of the amplifier.
The midrange frequency output is flat
at the center position. Rotate the control
counter clockwise for a “contoured”
sound (more distant, less midrange
output) or clockwise for a sound which
really cuts through. See pages 10-14
for technical specifications.
12. TREBLE: Use this to adjust the high
frequency level of the amplifier.
The high frequency output is flat
at the center position. See pages
10-14 for technical specifications.
