Features
In the world of high performance bass amps, Ampeg’s SVT amplifiers stand alone. In true Ampeg tradi-
tion, the SVT-4 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!
• DUAL SEPARATE POWER AMPLIFIERS: Operate in true stereo or mono bridged
mode for even greater output power (page 8,12).
• BIAMP CAPABLE: Adjustable crossover frequency control and low-to-high fre-
quency balance control allow you to fine tune the biamp abilities of the amplifier
(page 5,13).
• 5-POSITION MIDRANGE SELECTOR: Take your pick from the five center fre-
quency points available to get just the right midrange voice (page 4).
• COMPRESSION CONTROL: Allows you to control the dynamics of the tonal
response characteristics from the power amp; from punchy to compressed (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 5).
• TUNER OUT JACKS: Two jacks, one on the front panel, one on the rear panel.
Allows connection to an electronic tuner and provides an “always live” monitor feed
even when the output is muted (page 4,9).
• SPEAKON
®
JACKS: For more reliable connections at higher outputs and for mono
bridged connections (in addition to 1/4” speaker out jacks) (page 8).
• TRANSFORMER BALANCED LINE OUTPUTS: Independent level control. Two
transformer balanced XLR and two balanced/unbalanced 1/4” output jacks.
Switchable stereo or mono (one “wet,” one “dry” signal), pre- or post-EQ (page 8,9).
• STEREO EFFECTS LOOP: Connect your effects here for increased intensity and
quieter operation (page 9). This can be bypassed with front panel switch or
footswitch.
• POWER AMP IN/PREAMP OUT: Two separate loops, one for each channel: a sep-
arate preamp may be connected to the Power Amp In jack, and the Preamp Out
jack may be connected to a slave amp (page 8).
• FOOTSWITCH CONTROL: Use a footswitch to bypass the Effects Loop, and to
activate the Graphic EQ and the Mute feature (page 8).
• CIRCUIT BREAKER PROTECTION: A heavy duty resettable circuit breaker pro-
vides protection against fault conditions (page 8).
