Owner’s Manual

BASS AMPLIFIER

Model: BA-110

IMPORTANT SAFEGUARDS AND PRECAUTIONS:

All Ampeg products are designed for continuous safe operation, as long as common sense is used and steps are taken to help avoid certain problems. Abiding by the following rules can help prevent damage to your amplifier, yourself and others.

The amplifier is equipped with a three-pronged AC power cord. To reduce the risk of electrical shock, NEVER remove or otherwise attempt to defeat the ground pin of the power cord.
Connect the amplifier ONLY to a properly grounded AC outlet of the proper voltage for your amp.
Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and intense impact. (If the unit has been subjected to any of the preceding abuses, have it looked at by an authorized service center.)
NEVER set the amplifier on a support that might give out under its weight.
Always keep the total speaker impedance at or above the rated load.
Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the ampli-fier. Wipe it with a slightly dampened, lint-free cloth to remove dirt and film.
Do not use the amplifier if it has sustained damage to the chassis, controls, or power cord. Refer the unit to an authorized service center for inspection.
Amplifiers capable of producing high volume levels are also capable of inflicting per-manent hearing loss or damage, if the exposure to such levels is prolonged. Such damage is progressive and irreversible!

PRECAUTIONS

TOP PANEL:

1. 0dB INPUT: Connect your “passive” bass guitar here by means of a shielded instru-ment cable. This input is not padded and is best suited for basses without active elec-tronics or “hot” pickups.
2. -15dB INPUT: Connect your “active” bass here by means of 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-110 employs a built in limiter to keep the output clean at full power, however, extreme settings may cause some audible distortion.
4. CONTOUR: This switch, when de-pressed, boosts the high and low frequen- cies while cutting the midrange to provide a “funk” slap-bass tone.
5. LOW: Use this control to adjust the low frequency level of the amplifier. This control has a 28dB range at 100Hz.
6. MID: Use this control to adjust the midrange level of the amplifier. This control has a 26dB range at 600Hz.
7. HIGH: Use this control to adjust the high frequency level of the amplifier. This control has a 35dB range at 10kHz.
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-110 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 headphones into this jack. The internal speaker is disconnected when the headphones jack is used.
11. ON LED: This LED illuminates when the amplifier is plugged in and turned on.
12. POWER: Use this switch to turn the amplifier on and off – the top of the switch is depressed in the on position.
13. POWER CORD (rear panel, not shown): Use this cord to connect the amplifier to a suitable source of A.C. volt-age. This is a grounded, three- wire cord and must be connected to a properly grounded outlet. DO NOT attempt to defeat the ground connection of the power cord! If your amp was purchased outside of the United States, see the stick-er next to the A.C. connector for its power ratings. Follow the above guidelines.
