ESX VX3000 PRO (24V)

The ESX VX3000 PRO (24V) from the VISION VX PRO series is a high-performance digital monoblock amplifier designed specifically for vehicles with a 24-volt electrical system. This makes the amplifier particularly well-suited for use in trucks and tour buses where high-power subwoofers are to be operated.

Thanks to highly efficient Ultra Class D circuit technology, the VX3000 PRO (24V) delivers an output power of up to 3,000 watts RMS into 1 ohm with an efficiency of up to 96%. Despite these enormous power reserves, the amplifier impresses with its compact dimensions and robust aluminum heat sink, which supports effective heat dissipation.

A distinctive feature of the VX PRO series is its two RCA inputs with different sensitivity levels. The LOW INPUT is suitable for signal sources with low output voltage, while the HIGH INPUT is designed for more powerful preamp signals, such as those from DSP processors. This allows the amplifier to be optimally tuned to different audio systems.

A variable subsonic filter, an adjustable low-pass filter, and a bass boost are available for precise tuning to the connected subwoofer. Heavy-duty power and speaker connections, screw-type RCA jacks, a clipping indicator, and comprehensive protection circuits round out the features.
