With the two QUANTUM QL processors, ESX demonstrates what high-quality DSP can truly achieve. The exceptional units included are the best available: space in the equipped infrastructure and the use of two ADAU1452s, namely the top processors from Analog Devices. The difference becomes apparent: conventional DSPs usually feature only a single DSP core. However, with multiple channels and the corresponding equipped infrastructure, computational power becomes limited. Not so with the new top models from ESX, on the contrary. The two QL-DSPs have enough power to easily process not only 12 channels, but the developers have also integrated the revolutionary ESX Expert Staging Equalizer with balancing and leveling functions, allowing for further improvements in tuning. Thanks to the built-in Bluetooth receiver, the ESX DSP Toolkit app can be used live and in real-time from your smartphone - including HD audio streaming. The RC-DQ LCD remote control, available as an accessory, offers additional ease of use.

A powerful ARM Cortex® M4 High-Performance CPU with 240 MHz and 1024 kB of internal flash memory takes care of processing the commands. This enables real-time operation with maximum performance. With the new QL812SP, ESX also ensures its high standards in the field of high-quality DSP: In the testing evaluation of the magazine Car & Hifi 3/2022, the QL812SP was so convincing that the testers rated it not only as top-notch but also as the best DSP "under 2000 euros." This is outstanding, considering it is available for only 1000 euros.

Important note: For the ESX DSP Toolkit app to function on an Android smartphone, Bluetooth and GPS must be activated.
