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 preamp, 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.

•When using tall or stacked speaker cabinets, use them ONLY on a level surface. NEVER set tall or stacked

cabinets on a surface with more than a five degree incline since tipping or falling could occur, possibly caus-

ing serious injuries.

•Always keep the total speaker impedance at or above the rated load.

•Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the amp. 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!

SVT-2 PRO Bass Amplifier

An Introduction to your new Ampeg SVT-2 PRO Bass Amplifier

The harmonically rich sound and legendary performance of the AMPEG SVT are redefined in the SVT-2 PRO.

This dynamically powerful bass amplifier delivers a thundering 300 watts of unsurpassed quality, reliability and

tonal flexibility, offering the classic vibrancy of tubes as well as contemporary features.

All of the features and controls of your SVT-2 PRO are covered in detail within the pages of this owner’s

guide. We recommend going over them before you use the amplifier.

Features

In the world of high performance bass amps, Ampeg’s SVT amplifiers stand alone. Keeping with true Ampeg tra-

dition, the SVT-2 PRO Bass Amplifier offers you more performance and flexibility than any other amplifier 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.

• ATTENUATOR: A switchable input 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).

• BIAS ADJUSTMENT CONTROLS: Let you adjust the tube bias for proper operation (pages 5,7).

• SLAVE OUT: Use for powering another amp from the SVT-2 PRO’s preamp (page 5).
