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.
