ESX QL812SP HIGH END DSP with 12 channels with DUAL CORE 8x IN 12x OUT includes Bluetooth streaming and APP control.

With the two processors QL810SP and QL812SP, ESX shows what true high-end DSPs can do. The components equipped are also the best: not only have 32 bit audiophile converters from AKM series 5 been installed, two of the ADAU1452 are used and therefore the best processors from Analog Devices. This is exactly where the grain is separated from the chaff: conventional DSPs usually have only one DSP core. However, if a DSP has many channels and the corresponding equipment, computing power becomes scarce. Not so with the new ESX flagship models, quite the opposite. The two QL-DSPs have so much reserve that they can easily process not only 12 channels, but the developers have also implemented the revolutionary ESX Expert Staging Equalizer with balancing and level function, which allows further refinements in tuning, in addition to numerous functions.

A powerful high-performance ARM Cortex® M4 CPU at 240 MHz and internal flash memory of 1024 kB takes care of command processing. This is the only way to work in real time with maximum performance. With the new QL812SP, ESX is now consolidating its high standards also in the area of high-end DSPs: in the test review in the specialist magazine Car & Hifi 3/2022, the QL812SP was so convincing that the test editors not only classified it as a highlight, but also immediately as the best DSP "under 2000 euros". This is exceptional as it is available for only 1000 euros.

Test conclusion: "With the QL812SP, ESX has achieved great success. It is at the forefront with its superior hardware and the new software is a major step forward with powerful audio capabilities. If you add the generous equipment including Bluetooth and APP, the QL812SP for sound enthusiasts is the most attractive DSP on the market under 2000 euros." (Elmar Michels, Test Editor)
