This expansion module provides eight stereo AES/EBU digital audio inputs and eight stereo outputs (16 channels in and 16 channels out) via a 25-pin D-type connector, using the AES59 digital pinout for straightforward integration into professional broadcast and audio systems. Once installed, all inputs and outputs are available within the unit’s internal routing grid, accessible via the integrated web server. This enables flexible routing and control of digital audio signals, allowing seamless incorporation into existing workflows.
Product Features
8 stereo AES/EBU digital audio inputs and 8 stereo outputs (16 in / 16 out total channels).
25-pin D-type connector with AES59 digital pinout.
Full integration into the internal routing grid via web server.
Flexible routing of all input and output channels within the system.
Supplied with 4-pin power cable and 30-pin FFC audio/control cable.
Can be factory-fitted or retrofitted in the field.
Disassembly and reassembly process for installation.
Typical Applications
Ideal for use in outside broadcast (OB) vehicles, where space is limited and reliable, high-density digital audio routing is essential. This module enables multiple AES/EBU stereo pairs to be consolidated into a single, compact monitoring and control system, supporting efficient management of mission-critical audio workflows. It is also well suited to Master Control Room (MCR) environments, where centralised handling of digital audio signals is required for playout, monitoring, and compliance operations. In this role, it provides flexible routing of multiple AES/EBU sources, supporting accurate signal management, coordination of transmission feeds, and overall system integrity within the broadcast chain.
