VE900.7SP by ESX
The ESX VE900.7SP is an 8-Channel DSP Amplifier with Class D 7-Channel Amplifier and digital Full HD Audio 8-Channel Signal Processor. The total power is 900 Watts RMS. The DSP operates with an Analog Devices ADAU1452 32 Bit processor at 294 MHz and 96 kHz Full HD Audio, combined with AKM Velvet Sound Series 5 32 Bit A/D and D/A converters. Integrated are HP/LP/BP filters with 6–48 dB, phase shift, and a delay correction of 0 to 20 ms in 0.01 ms steps. Features include an input mixer, Subwoofer control, and a Priority Input Mode for digital input signals. The DSP control is done via the ESX DSP Toolkit through PC software for Microsoft Windows 10 or newer, as well as through the integrated Bluetooth receiver with antenna for app control and Full HD Audio streaming. Bluetooth 5.0 supports A2DP/AVRCP with codecs aptX, aptX LL, aptX HD, AAC, and SBC. REM OUT function and MODE switch input (Preset Auto Switch) are available; optionally, the RC-DQ LCD remote control is available. The frequency response is from 5 to 45,000 Hz, the signal-to-noise ratio (A-weighted) is 106.5 dB, and the total harmonic distortion is 0.005% @ 1 Watt RMS or 0.003% @ 5 Watts RMS. The operating voltage is 7.5 to 17 V, and the dimensions are 250 x 50 x 150 mm.
