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 ofa 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.

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, NEVERremove or otherwise attempt to defeat the ground pin of
the power cord.
•Connect the amplifier ONLYto 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.)
•NEVERset 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! 
THIS EQUIPMENT HAS BEEN DESIGNED AND ENGINEERED TO PROVIDE SAFE AND RELIABLE OPERATION. IN ORDER TO PROLONG THE LIFE OF THE
UNIT AND PREVENT ACCIDENTAL DAMAGES OR INJURY, PLEASE FOLLOW THESE PRECAUTIONARY GUIDELINES:
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT OPEN CHASSIS; DO NOT DEFEAT OR REMOVE THE GROUND PIN OF THE POWER
CORD; CONNECT ONLY TO A PROPERLY GROUNDED AC POWER OUTLET.
WARNING:TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.
CAUTION: NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
CAUTION: OUR AMPLIFIERS ARE CAPABLE OF PRODUCING HIGH SOUND PRESSURE LEVELS. CONTINUED EXPOSURE TO HIGH SOUND PRESSURE
LEVELS CAN CAUSE PERMANENT HEARING IMPAIRMENT OR LOSS. USER CAUTION IS ADVISED AND EAR PROTECTION IS RECOMMENDED IF UNIT IS
OPERATED AT HIGH  VOLUME.
