Product Description

The Ampeg SVT-4PRO redefines the harmonically rich sound and legendary performance of the Ampeg SVT. This versatile and powerful bass amplifier delivers up to 1600 watts of unsurpassed musical power, and offers the classic vibrancy of tubes with several outstanding features.

In the world of high performance bass amps, Ampeg’s SVT amplifiers stand alone. In true Ampeg tradition, 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 the SVT-4PRO - features which set it apart from the competition!

Dual Seperate Power Amplifiers
Operate in true stereo or mono bridged mode for even greater output power

Biamp Capable
Adjustable crossover frequency control and low-to-high frequency balance control allow you to fine tune the biamp abilities of the amplifier

5 Position Midrange Selector
Take your pick from the five center frequency points available to get just the right midrange voice

Compression Control
Allows you to control the dynamics of the tonal response characteristics from the power amp, from punchy to compressed

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.

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

Speakon Jacks
For more reliable connections at higher outputs and for mono bridged connections (in addition to 1/4-inch speaker out jacks)

Transformer Balanced Line Outputs
Independent level control - two transformer balanced XLR and two balanced/unbalanced 1/4-inch output jacks - switchable stereo or mono (one wet, one dry signal), pre- or post-EQ

Stereo Effects Loop
Connect your effects here for increased intensity and quieter operation - can be bypassed with front panel switch or footswitch.

Power Amp In/Preamp Out
Two separate loops, one for each channel: a separate preamp may be connected to the Power Amp In jack, and the Preamp Out jack may be connected to a slave amp

Footswitch Control
Use a footswitch to bypass the Effects Loop, and to activate the Graphic EQ and the Mute feature

Circuit Breaker Protection
A heavy duty resettable circuit breaker provides protection against fault conditions <

The sound is in your head. You've played countless instruments in search of the ultimate soul mate. Now you need an amp that will speak your sound to the audience. That's where the Pro Series heads live. All Ampeg Pro Series heads feature multi-tube preamps (not a single 12AX7 like many competitors), five position mid frequency selection, and Neutrik SpeakOn connectors that lock and provide better conductivity. A Mute button lets you change instruments in the middle of a set without the annoying pop, and a Tuner Out jack that stays active even with Mute button on. Pro Series heads are built for the long haul. The units remain cool with variable speed fans that only turn as the temperature dictates. DC supplied filaments ensure noise-free tube performance. And the 1/8-inch thick extruded aluminum front panels not only allow safe racking, the contoured fronts have an awesome look. The 1200 watt Ampeg SVT-4PRO is the industry's highest powered bass amp. Your creative mind now has the palette to deliver the goods.
