ESX D66SP

With the ESX D66SP from the DIRECTION series marks the beginning of a new generation of sophisticated digital sound optimization. High-quality, carefully selected components, powerful signal processing, and extensive adjustment options form the foundation for precise and customized sound tuning in your vehicle.

At its core is a high-performance 32-bit DSP chip from Analog Devices running at 294 MHz with a sampling rate of 96 kHz. Combined with high-quality AKM Velvet Sound A/D and D/A converters, the processor enables exceptionally detailed signal processing. Using the ESX DSP Toolkit PC software, you can individually adjust crossovers, equalizers, time alignment, level, and phase.

Integration into modern vehicles was also taken into account. Six high-level inputs with EPS PRO protection circuitry, an automatic power-on function, and six balanced RCA outputs with 6 V RMS enable integration into existing sound systems.

With the optional Bluetooth 5.0 module (BT-D), the DSP can also be controlled in real time via the ESX DSP Toolkit app. At the same time, it enables wireless HD audio streaming. The optional LCD remote control (RC-DQ) enhances ease of use.
