Digital 6-Channel Sound Processor

The prelude to the new DSP (r)evolution from ESX are the two digital sound processors from the DIRECTION series. Finest selected components, optimally tuned and combined into an ingenious overall concept, perfectly adjustable down to the smallest details with the newly developed PC software, make sound enthusiasts click their tongues respectfully. With the optional Bluetooth 5.0 upgrade set BT-D, the app version of the ESX DSP Toolkit can also be used live and in real time from the smartphone - including HD audio streaming. The RC-DQ LCD remote control, which is available as an accessory, offers additional ease of use.


Thanks to the latest state-of-the-art analog/digital converter from AKM Velvet Sound™, the sound processing of the Analog Devices™ 32 bit/295 MHz DSP chips takes place in the full HD audio range at 96 kHz. In addition to audiophile aspects, a smooth integration into modern vehicles was also considered. EPS PRO protective circuit and high-level inputs with Auto Turn-On Function (pluggable from 1-15 V or 15-40 V via jumper) as well as symmetrical RCA low-level outputs with 6 V/RMS are standard on board. Sound tuning redefined...
