Resumen del manual
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 controls (#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 connect 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. BA-112 BASS AMPLIFIER 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 amplifier. Wipe it with a slightly dampened, lint-free cloth to remove dirt and film. • Don’t 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 permanent 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 AND RELIABLE OPERATION. IN ORDER TO PROLONG THE LIFE OF THE UNIT AND PREVENT ACCIDENTAL DAMAGES OR INJUR GUIDELINES: CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT OR REMOVE THE GROUND PIN OF THE POWER CORD; CONNECT ONLY TO A PROPERLY GROUNDED WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT THIS EQUIPMENT TO RAIN OR MOISTURE. CAUTION: NO USER-SERVICEABLE PARTS INSIDE. REFER SER VICE PERSONNEL. CAUTION: OUR AMPLIFIERS ARE CAPABLE OF PRODUCING HIGH SOUND PRESSURE LEVELS. CONTINUED EXPOSURE TO HIGH SOUND PRESSURE LEVELS CAN CAUSE PERMANENT HEARING IMP AND EAR PROTECTION IS RECOMMENDED IF UNIT IS OPERATED AT HIGH VOLUME. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
