ESX QM66SP

The ESX QM66SP from the QUANTUM series is a high-quality, 6-channel digital sound processor designed for precise sound optimization of high-end car audio systems. Housed in a rugged aluminum enclosure, the DSP combines extensive adjustment options with modern signal processing and versatile connectivity.

At the heart of the QM66SP is a powerful Analog Devices™ 32-bit DSP running at 294 MHz with 96 kHz signal processing. High-quality 32-bit A/D and D/A converters from AKM Velvet Sound™ ensure precise conversion of audio signals. Thanks to high-level and RCA inputs, the processor can be integrated into both aftermarket systems and numerous factory-installed sound systems.

The built-in Bluetooth® receiver not only enables wireless audio streaming but also allows you to control and adjust the DSP using the ESX DSP Toolkit app. Alternatively, you can perform the entire configuration using the ESX DSP Toolkit software on a Windows PC. A total of eight memory slots are available for different sound setups.

With comprehensive crossovers, parametric equalizers, time alignment, level and phase adjustments, and a freely configurable input mixer, the QM66SP offers numerous options for customizing the sound system. Features such as Priority Input Mode, Preset Auto Switch, and EPS® PRO also simplify integration into modern vehicles.
