ATD808 - 8-Channel Digital Signal Processor
DSP Processor
ATD808
8-channel DSP with 48V phantom power, AEC/AFC/ANS/AGC algorithms, USB audio, 8 GPIO ports, camera tracking, and Ethernet control — designed for conferencing, classrooms, and AV installations.
Product Description
The ATVI ATD808 is a versatile 8-channel digital signal processor built on A-DSP architecture with 40-bit floating point processing, up to 400MIPS capacity, and 1600MFLOPS performance. It provides eight analog inputs with optional 48V phantom power (10mA max), eight balanced analog outputs, and a built-in USB audio channel in a compact 1U rack-mountable form factor.
The USB audio channel connects directly to a PC for MS Teams, Google Meet, and other conferencing platforms. Eight GPIO multi-function ports enable external device control including camera tracking and Ducker support, and RS232, RS485, and dedicated Ethernet ports allow flexible system control. Multiple ATD808 units can be configured simultaneously from a single PC.
Core DSP algorithms — AEC, AFC, ANS, and AGC — apply to all analog inputs and the USB channel, with sixteen onboard presets for instant scene recall. An internal universal power supply and CE/FCC/RoHS certification ensure worldwide deployment.
