ESX QL812SP – High Performance 12-Channel Digital Sound Processor
Full description
The ESX QL812SP embodies excellence in digital audio processing. Designed for demanding audiophiles, it incorporates two Analog Devices ADAU1452 processors , ensuring optimal signal management with 32-bit precision and a 96 kHz sampling rate.
Unlike conventional DSPs, which are often limited by a single chip, the QL812SP benefits from increased computing power, enabling advanced processing on 12 channels without compromising on sound quality. This model also integrates the ESX Expert Staging Equalizer , offering balancing and level adjustment for ultra-precise sound adjustment.
The integrated Bluetooth receiver allows real-time control via the ESX DSP Toolkit app (available on iOS and Android) and offers HD audio streaming with support for aptX, aptX LL, AAC and SBC codecs.
In laboratory testing, the QL812SP was voted best DSP "under €2000" by Car & Hifi magazine (3/2022), offering exceptional performance at an unbeatable price.
