Digital sound processing is more than just an optional extra when talking about top end in-car hi-fi systems – something that ESX exemplifies with the QL812SP. A flexible 12-channel model packed with the latest advanced technologies, it features 32-bit processing courtesy of Analog Devices’ dual ADAU1452 chips and a 32-bit AKM ‘Velvet Sound’ signal converter. These have the capacity to support its 31-band EQ, plus other functions, to all 12 channels with exceptional sound quality, while an Expert Mode allows grouping of channels and simultaneous stereo processing to achieve perfect staging. Bluetooth 5.0 compatibility brings best-quality audio streaming plus programming via an Android app. This DSP engine is unbeatable at the price!
