Product Overview
The Model 544D represents an advanced audio interface engineered to seamlessly integrate with Dante® audio-over-Ethernet media networking technology. Offering two analog line-level inputs and outputs, it provides extensive connectivity for diverse applications. Additionally, the unit features two installer-accessible general-purpose inputs (GPI) and general-purpose outputs (GPO). Engineered as a dual-channel analog input/output interface, it boasts configurability through the STcontroller software application. Encased in a lightweight tabletop enclosure, it also supports optional mounting kits for versatile deployment. The interface is powered via Power-over-Ethernet (PoE) or 12 volts DC, ensuring flexibility in power sourcing.
