The chart below shows the U.S. Government Occupational Safety and Health Administration (OSHA) regulations which were in effect at the time of this publication for permissible noise exposure, per 29CRF1910, Table G-16. According to OSHA, any exposure in excess of those listed above could result in some hearing loss. "IT IS NECESSARY FOR THE USER TO REFER TO THE INSTRUCTION MANUAL" "REFERREZ-VOUS AU MANUAL D'UTILISATION" "UNBEDINGT IN DER BEDIENUNGSANLEITUNG NACHSCHLAGEN" EXPLANATION OF GRAPHICAL SYMBOLS: "DANGEROUS VOLTAGE" "DANGER HAUTE TENSION" "GEFAHLICHE SPANNUNG" = = Features In the world of high performance bass amps, Ampeg amplifiers stand alone. In true Ampeg tradition, your new SVT-150H offers you more power, performance and flexibility than any other bass ampli- fier in its class. Here are just some of the outstanding features of your new amplifier - features which set it apart from the competi- tion! • 9-BAND GRAPHIC EQ: Use as a “second channel” for bass solos, or to shape your sound to your own exacting standards. • BALANCED LINE OUTPUT: XLR with independent level control switch to patch into house consoles, mixing boards, or external power amplifiers. • EFFECTS LOOP: For increased intensity and quieter operation of exter- nal effects. • DRIVE CONTROL: To add harmonic content for tube-like overdrive.

INPUT: Connect your bass guitar here using a shielded instrument cable. 2. -15dB PAD: If your bass has high-output pickups or active electronics you may notice the Peak LED (#3) flashes or stays on even at low settings of the Gain control (#4). To keep the signal clean, switch in the Pad. This will attenuate the input signal to the preamp allowing you to get the best signal to noise ratio for your bass. 3. PEAK LED: This LED lights whenever any preamp stage is near the point of being over- driven. Adjust the Gain control (#4) until a strong signal from your bass causes this LED to flicker. NOTE: If the LED stays on with the Gain at a low setting, use the 15dB Pad (#2) to attenuate the input signal and readjust the Gain. 4. GAIN: This serves as the input level control for the amplifier. For the best signal-to-noise ratio set this control so the Peak LED (#3) flashes when you strike a string fairly hard. 5. DRIVE: This control is used to overdrive the preamp in order to get various harmonic enhancement or distortion sounds. In the fully counterclockwise position the preamp is in the cleanest condition. As the control is rotated 8910 11 clockwise, signal level is increased to drive the preamp harder (into distortion). The tone of the signal is also changed to provide a smoother overdrive. The tone controls may have to be readjusted to obtain the overall desired tone. The Gain control (#4) and -15dB Pad (#2) interact with the Drive control. For greater overdrive, the Pad switch should be out and the Drive control fully clockwise. Use the Gain control to set the amount of overdrive desired. The Peak LED (#3) will glow steadily when the amp is used in this manner. 6. BASS: This knob serves as the primary low frequency control. This allows for a range of 8dB of cut or boost at 50Hz. 7. ULTRA-MID: This is the primary midrange control. Rotate the control to the left of center for a “contoured” sound (more distant, less midrange output) or to the right of center for a sound that really cuts through. 8. TREBLE: This knob serves as the primary high frequency control. This allows for a range of 17dB boost or 22dB cut at 5kHz. 9. EQ ON LED: This LED indicator lights when you engage the EQ by the front panel Master control (#11) or the footswitch (#23, rear panel). 1213 14 10. GRAPHIC EQ: These slide controls allow you to adjust the output of the frequencies shown beside each control. The center position of each control is flat (no boost or cut). These controls only affect the sound when the EQ is turned on. 11. MASTER: Set the overall output level of the amplifier with this control. The Effects Loop and Balanced Out (#18, 19, 22) are not affected by the Master control. Pulling the Master control turns on the Graphic EQ (#10). When the footswitch is used, the front panel switch is bypassed. 12. LIMIT LED: This LED indicator will flash on any time the internal limit circuit is called upon to keep amplifier’s output signal clean. This indicates that the amplifier is nearing full output and the limiter is keeping it from clipping the output signal. 13. POWER ON LED: This LED indicator lights when the POWER switch (#14) is turned on. 14. POWER SWITCH: This heavy-duty rocker switch applies AC power to the amplifier: the amp is ON in the up position, OFF in the down position. 1.
