This expansion module provides eight channels of high-quality analogue audio input via a single 25-pin D-type connector, using the AES-59 standard pinout for straightforward integration with professional audio systems. A second 25-pin D-type socket offers loop-through outputs for all channels, allowing the incoming signals to be passed on to additional equipment without the need for external distribution hardware. Once installed, all eight analogue inputs are automatically made available within the unit’s internal routing grid, accessible via the integrated web server. This enables flexible assignment and control of audio sources, making it easy to incorporate external analogue signals into your monitoring or processing workflow.

Typical Applications
Ideal for use in outside broadcast (OB) vehicles, where space is at a premium, this module enhances a compact, high-density, mission-critical monitoring hub with additional analogue audio inputs. Its integration allows external analogue sources to be easily brought into a single control point, supporting the audio supervisor in managing multiple signals efficiently. It is equally suited to Master Control Room (MCR) environments, where reliable handling of diverse audio sources is essential. In this context, the module enables seamless incorporation of analogue feeds into workflows for signal quality control, playout coordination, and compliance monitoring, all within a centralised monitoring system.
