Anleitung Zusammenfassung
The SVP-PRO is the preamp section of our much-respected SVT-2 PRO. All of the features and controls of your SVP-PRO are covered in detail within the pages of this user’s guide. We recommend going over them before you use the preamp. Features In the world of high performance bass amps, Ampeg’s SVT amplifiers stand alone. Keeping with true Ampeg tradition, the SVP-PRO Bass Preamp offers you more performance and flexibility than any other preamp in its class. Listed below are some of the outstanding features of your new preamp - features which set it apart from the competition! Additional information on these features can be found on the pages indicated. • PAD: A switchable attenuator pad, this feature is perfect for basses with active electronics or very “hot” pickups (page 4). • MUTE SWITCH: Lets you cut the sound from the amp, letting you tune your bass in private (page 4). • ULTRA LOW, ULTRA HIGH AND BRIGHT SWITCHES: Lets you tailor your sound in many different ways “with the touch of a button” (page 4). • 5-POSITION MIDRANGE SELECTOR: Take your pick from the five center frequency points available to get just the right midrange voice (page 4). • 9-BAND GRAPHIC EQ: Use as a “second channel” for bass solos, or to shape your sound to your own exacting standards. An independent level control lets you adjust the Graphic EQ volume. Switchable at front panel or with a footswitch (page 4). • TRANSFORMER BALANCED LINE OUT JACK: For connection to a recording console, PA system or external power amplifier. Switchable for Pre- or Post-EQ operation (page 5). 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 equipment, yourself, and others. • The unit 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 unit ONLY to a properly grounded AC outlet of the proper voltage for your unit. • 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 unit on a support that might give out under its weight. • Unplug the unit before cleaning it. NEVER spray liquid cleaners onto the unit. Wipe it with a slightly dampened, lint-free cloth to remove dirt and film. • Do not use the unit if it has sustained damage to the chassis, controls, or power cord. Refer the unit to an authorized service center for inspection. • Audio equipment 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! Consider using quality hearing protection devices. 4 SVP-PRO Bass Preamp The Front Panel: 1. INPUT: Use this jack to connect your bass to the preamp by means of a shielded instrument cable. 2. MUTE: This switch, when depressed, mutes the signal at all output jacks except the Tuner Out jack (#27). 3. PAD: This switch, when depressed, attenuates the input signal by 15dB. If your bass has active pickups, depress this switch to better accommodate its output signal. 4. GAIN: Use this control to adjust the level of the input signal. When properly set, the Peak LED (#5) will flash on strong signals. For the best signal to noise ratio set the Gain control to the highest useable setting and adjust the Drive and Master controls (#8, 18) to obtain the desired output level. 5. PEAK/MUTE LED: This LED illuminates when the preamp signal approaches clipping. When the Mute switch (#2) is engaged, this LED stays on as a visual indicator that the Mute function is active. 6. BRIGHT: This switch, when depressed, boosts the upper mid and high frequencies. 7. ULTRA LO: This switch, when depressed, provides emphasis to the low end by boosting the low frequencies and cutting the mid frequencies. 8. DRIVE: Use this control to adjust the level of the distortion. In the fully counterclockwise position the preamp is in the cleanest, traditional SVT condition. As the control is rotated clockwise, the distortion level is increased. The tone of the signal is also changed to provide a smoother overdrive. The tone controls may have to be readjusted to obtain the desired tone. The Gain control (#4) and Pad (#3) interact with the Drive control. For greater overdrive, the Pad switch (#3) should be out and the Drive control should be rotated fully clockwise. Use the Gain control (#4) to set the amount of overdrive desired. The Peak LED (#5) will remain illuminated when the amplifier is used in this manner. 9. BASS: Use this control to adjust the low frequency output level. This control provides 12dB of cut or boost at 40Hz. 10. MIDRANGE: Use this control to adjust the mi...
