ATEN AD202E Digital Signal Processor (DSP)

The AD202E supports the conversion of 2 balanced / unbalanced Line/Mic level audio inputs with selectable individual 48V Phantom power into 2 Dante outputs as well as 2 Dante audio channels into 2 balanced / unbalanced line level outputs for versatile connectivity. It also enables 4 × 4 analog and Dante matrix mixing, allowing users to flexibly route any input to the assigned output, elevating sound performance. It supports 24 bit and offers sampling rate options of 44.1k, 48k, 88.2k, and 96 kHz to meet different environment needs. With AES67 compliance, the AD202E enhances interoperability between different audio networking protocols and devices.

Designed to enhance meeting experiences, the AD202E adopts Acoustic Echo Cancellation (AEC) technology to prevent echoes in a conferencing environment and Feedback Suppressor (FBS) to automatically detect and reduce feedback. Its built-in DSP allows 24 presets and quick setting adjustment through the PC-based app Audio Wizard / ATEN VK control system via LAN / RS-232. Plus, the AD202E comes with a selectable automatic Standby Mode for energy-saving purposes, switching the unit to Standby Mode automatically when the signal level runs lower than −50 / −60 / −70 dBu for a selected duration (10 / 30 / 60 minutes).

Other highlights include the support for Dante Daisy Chaining to help simplify system infrastructure wiring and for redundancy operation via PoE to eliminate the need for additional cable installations. The AD202E’s compact, half-rack size enclosure makes installation under desks or on any flat surface easy. It is perfect for on-line conferences or distance learning applications that require high quality, dynamic sound performance and intelligible audio at the far end within Dante audio networking environments.
