The COMM-TEC DAN-B202 is a 2x2 Dante/AES67 Surface Mount Interface designed for integrating analog audio into networked AV systems. It offers high-quality, uncompressed audio with near-zero latency, making it suitable for a wide range of applications from simple installations to large-capacity networks running thousands of audio channels. The device supports PoE (IEEE802.3af) power capability and a small form factor, making it easy to put Dante connectivity wherever needed.

Function Description

The DAN-B202 serves as a bridge between analog audio signals and a Dante/AES67 network. It features two analog inputs (MIC/LINE IN) and two analog outputs (LINE OUT), both using 3-pin Green Terminal Blocks. The device also supports 48V phantom power, which is software selectable for each input.

Key functions include:

Audio Conversion: Converts analog microphone/line level signals to Dante/AES67 network audio and vice versa.
Phantom Power: Provides 48V phantom power for condenser microphones on its inputs.
Gain Control: Offers adjustable gain for both inputs and outputs, allowing precise level matching.
Volume Control: Output volume can be controlled from -60dB to 0dB.
Sample Rate Support: Supports 44.1kHz or 48kHz audio sample rates.
Network Connectivity: Connects to a Dante network via an RJ45 Ethernet port, supporting PoE.
Web-UI Control: Allows users to interact with the device through a web-based graphical interface for configuration and monitoring.
Dante Controller Integration: Fully compatible with Dante Controller software for comprehensive network management, routing, and device configuration.
API Commands: Supports control via Telnet using specific commands for various functions like gain adjustment, mute, phantom power, and status queries.
