B-Stock ESX QM66SP

B-Grade Description:
Manufacturing defect: The DSP technology is housed in the ESX D66SP case, but the internal components (technology) are from the QM66SP. Otherwise, the item is brand-new and unused, and is delivered complete and in its original packaging

Following the highly successful launch of the DIRECTION sound processors (EISA Award for the D68SP), ESX is ushering in the next generation with the QUANTUM QM66SP. The new 6-channel processor is integrated into a high-quality aluminum heat sink and offers even better standard features. Thanks to the built-in Bluetooth receiver, the app version of the ESX DSP Toolkit can be used live and in real time from a smartphone—including HD audio streaming. The RC-DQ LCD remote control, available as an accessory, offers additional ease of use.

Thanks to state-of-the-art analog-to-digital converters from AKM Velvet Sound™, the Analog Devices™ 32-bit/295 MHz DSP chips process audio in the Full HD range at 96 kHz. In addition to audiophile features, seamless integration into modern vehicles was also taken into account. EPS PRO protection circuitry and high-level inputs with an automatic power-on function (selectable via jumper from 1–15 V or 15–40 V), as well as balanced RCA low-level outputs with 6 V/RMS, are included as standard. Sound tuning redefined
