With the two processors QUANTUM QL, ESX shows what real high-end DSPs can do. Even the equipped components are the finest: not only that audiophile 32-bit converters from AKM's 5-series were installed, two of the ADAU1452 and thus the best processors from Analog Devices are used. This is exactly where the wheat is separated from the chaff: Conventional DSPs usually only have one DSP core. However, if a DSP has many channels and the corresponding equipment, computing power becomes scarce. Not so with the new ESX top models, on the contrary. The two QL-DSPs have so much reserve that they can easily process not only 12 channels, but the developers also implemented the revolutionary ESX Expert Staging Equalizer with balance and level function, which enables further refinements in fine tuning, in addition to numerous functions. Thanks to the integrated Bluetooth receiver, the app version of the ESX DSP Toolkit can be used live and in real time from your smartphone - including HD audio streamingThe RC-DQ LCD remote control, which is available as an accessory, offers additional ease of use.
