All of the features and controls of your SVT-3 PRO are covered in detail within the pages of this owner’s guide. We recommend that you go over them before you use the amplifier. Features In the world of high performance bass amps, Ampeg’s SVT amplifiers stand alone. In true Ampeg tradition, the SVT-3 PRO offers you more power, performance and flexibility than any other bass amplifier in its class. Below are some of the outstanding features of your new amplifier - features which set it apart from the competition! • 5-POSITION MIDRANGE SELECTOR: Take your pick from the five center frequency points available to get just the right midrange voice (page 3). • TUBE GAIN: Control the dynamics of tonal response characteristics from the power amp; from punchy to compressed (page 3). • 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 (page 3). • TRANSFORMER BALANCED LINE OUTPUTS: Independent level control. One balanced XLR and one balanced/unbalanced 1/4” jack to patch into house consoles, mixing boards, or external power amplifiers (page 4). • EFFECTS LOOP: Connect your effects here for increased intensity and quieter operation (page 5). • POWER AMP IN AND PREAMP OUT: A separate preamp may be connected to the Power Amp In jack, and the Preamp Out jack may be connected to a slave amp.
