ATD300W-AIO - All-in-One DSP with Amplifier & Wireless Mics
All-in-One DSP Processor
ATD300W-AIO
All-in-one digital audio processor integrating DSP, a 2×150W amplifier, and a UHF wireless microphone system — with AEC/AFC/ANS, camera tracking, 8 GPIO, 100 scene presets, and web control for conference rooms and auditoriums.
Product Description
The ATVI ATD300W-AIO is a highly integrated all-in-one digital audio processor that combines DSP audio processing, a 2×150W digital amplifier, and a UHF dual-channel wireless microphone system in a single 1U rack-mountable chassis. Powered by a high-performance 32-bit floating point DSP with 24-bit/48kHz A/D–D/A conversion and a 21-stage preamplifier circuit, it delivers professional-grade audio for conferences, auditoriums, and live installations.
It provides 8 balanced analog inputs with 48V phantom power and 51dB preamplification, 8 balanced analog outputs, USB Type-A for music playback and recording, RS232, RS485, Ethernet, and 8 programmable GPIO ports (3.3~24V level support). Camera tracking is built in with VISCA, PELCO-D, and PELCO-P protocol support, and a built-in web controller works on Windows, macOS, Linux, Android, and iOS.
DSP algorithms include AFC (Feedback Cancellation), AEC (Echo Cancellation), and ANS (Noise Suppression), with automatic mixing, expander, compressor, auto-gain, 5-band parametric EQ per input, and 31-band graphic EQ, crossover, delay, and limiter per output. The integrated UHF wireless system operates on 610–670MHz with 200 selectable channels, ACT auto-tracking, and 80m effective range. 100 scene presets can be stored and exported for backup.
