ESX VE900.7SP

The ESX VE900.7SP from the VISION ELITE series combines a powerful 7-channel Class-D amplifier with a high-quality 8-channel digital sound processor in an exceptionally compact enclosure. With a total RMS power rating of 900 watts, state-of-the-art 32-bit DSP technology, and a comprehensive range of features, the amplifier offers versatile options for customizing the sound of high-end car audio systems.

Five amplifier channels each deliver 100 watts RMS at 4 or 3 ohms and are suitable, for example, for driving the front and rear speakers as well as a center speaker. Two additional high-power channels each deliver 200 watts RMS at 2 ohms and are particularly well-suited for high-output woofers. This makes the VE900.7SP ideal, among other things, for upgrading BMW and Mercedes-Benz sound systems equipped with factory-installed under-seat or footwell subwoofers.

Inside, the powerful Analog Devices ADAU1452 DSP processor features 32-bit signal processing and a sampling rate of 96 kHz. High-quality AKM Velvet Sound A/D and D/A converters ensure precise digital signal processing. Extensive customization options—such as parametric equalizers, digital crossovers, time alignment, and individual level adjustments—allow for detailed tuning to the vehicle and the speakers being used.

The ESX DSP Toolkit software allows you to easily configure the built-in sound processor on a Windows PC. Thanks to the built-in Bluetooth 5.0 module, you can also control the DSP wirelessly via the ESX app and stream high-quality music.

The six high-level inputs with EPS PRO technology enable integration into modern vehicles equipped with factory-installed radios and speaker diagnostics. Additionally, there are six balanced RCA inputs, one optical digital input, and one processed subwoofer RCA output. This allows an additional power amplifier for a separate subwoofer to be integrated into the system if needed.

With dimensions of just 250 x 50 x 150 mm, the VE900.7SP can be installed even in tight spaces.
