1. 0dB INPUT: Connect your “passive” bass
guitar here using a shielded instrument
cable. This input is not padded and is best
suited for basses without active electronics
or “hot” pickups.
2. -15dB INPUT: Connect your “active” bass
here using a shielded instrument cable. This
input is padded 15dB and is best suited for
basses with active electronics and/or “hot”
pickups.
3. VOLUME: Use this control in conjunction
with your instrument’s volume controls to
adjust the output level of the amplifier. The
BA-112 employs a built in limiter to keep the
output clean at full power.
4. STYLE: This five-position switch allows
you to vary the tone of the amplifier.
Experiment with the Style and other eq con-
trols (#5,6,7) for the results which suit you
best.
5. TREBLE: Use this control along with the
style control to adjust the high frequency
level of the amplifier. The treble control has
a 36dB range at 10kHz.
6. ULTRA MID: Use this control along with
the style control to adjust the midrange level
of the amplifier. This control has a 30dB
range @ 500Hz.
7. BASS: Use this control along with the
style control to adjust the low frequency
level of the amplifier. This control has a
36dB range @ 50Hz.
8. CD INPUT: Use these RCA jacks to con-
nect the line level (or headphones) output of
a CD player or tape deck. The two jacks
sum the stereo signal into a mono signal
which is fed into the BA-112 just prior to its
power amplifier. Use the volume control on
the CD or tape player to control the level of
this signal.
9. LINE OUT: This jack supplies a post-eq,
unbalanced line level signal for connecting
to a house sound board, recording unit or
external amplifier. The level of this signal is
controlled by the Volume control (#3).
10. HEADPHONES: For private practice
sessions, plug a pair of headphones here.
The internal speaker is disconnected when
the headphones jack is used.
11. ON LED: This LED lights when the
amplifier is plugged in and turned on.
12. POWER: Use this switch to turn the
amplifier on and off – on is in the up position.
