ESX VX3000 PRO

With the VISION VX PRO series, ESX is setting new standards in performance, efficiency, and compact design. The ESX VX3000 PRO is a high-performance digital monoblock amplifier designed specifically to drive high-power subwoofers. Thanks to modern Ultra Class D circuit technology, the amplifier achieves an output power of up to 3,300 watts RMS at 1 ohm with an efficiency of up to 96%.

Despite its enormous power reserves, the VX3000 PRO impresses with its compact dimensions and a high-quality aluminum heat sink that ensures effective heat dissipation. Sturdy power and speaker connections, as well as screw-mounted RCA jacks, ensure a reliable connection.

A distinctive feature of the VX PRO series is its two separate RCA inputs with different input sensitivities. The LOW INPUT is suitable for car stereos and signal sources with low output voltage, while the HIGH INPUT is designed for more powerful signal sources such as DSP processors or high-to-low converters. This allows the amplifier to be optimally adapted to different audio systems.

A variable low-pass filter, an adjustable subsonic filter, and a bass boost are available for precise adjustment of the bass range. A clipping LED and a triple protection circuit round out the extensive feature set.
