ESX D68SP

The ESX D68SP from the DIRECTION series is a high-quality, 8-channel digital sound processor designed for high-end car audio systems. Featuring state-of-the-art DSP technology, precise signal processing, and extensive customization options, it enables customized sound optimization at the highest level.

At its core is a high-performance Analog Devices™ 32-bit DSP running at 294 MHz with a sampling rate of 96 kHz. In combination with the high-quality AKM Velvet Sound™ A/D and D/A converters, the processor ensures exceptionally precise and detailed audio signal processing.

The ESX DSP Toolkit software allows you to individually configure all sound parameters. These include comprehensive parametric equalizers, active crossovers, time alignment, phase adjustments, and flexible signal routing. Up to eight different sound setups can be saved and recalled as needed.

Integration into modern vehicles was also taken into account. Six high-level inputs with the EPS PRO fault protection system, an automatic power-on function, and an optical digital input enable integration into numerous factory-installed audio systems.

With the optional BT-D Bluetooth module, the processor can be controlled in real time via a smartphone app. The module also enables wireless HD audio streaming. The optional RC-DQ LCD remote control is available for convenient operation.
