The 850D-DA offers linked or independent volume control for each room, and accepts up to twelve input signals from a wide variety of digital or analogue audio sources, including DVD and Blu-Ray players, media servers, CD players, cable and satellite boxes, digital music players, and more.

The Vantage 850D-DA is the newest component in the Vantage line of home control and automation systems incorporating highly customisable touchscreen interfaces, lighting controls, home theatre components and more, all based around the InFusion System controller and communicating via Vantage Ethernet Bus Control.

The Vantage 850D-DA has six amplified stereo outputs with 50W per channel (into 8-ohms, or 75W into 4-ohms), plus two stereo line level outputs (pre-amplified, and fully controllable). It has eight analogue inputs and 12 digital inputs. Media files are accessed through a network port. There are also two doorbell inputs, a USB port, and Amp On control connections.

Fifteen program presets, including momentary and two page presets, provide homeowners and their guests with easy to use customised audio control options (via touchscreen interfaces). Zones can be selectively linked together. Each analogue input has its own software-based gain control, and also features an audio delay setup adjustment that supports Vantage 1080HD integration.

Like all Vantage products, the 850D-DA is designed to maximise control, simplify functionality, and expedite installation. The amplifiers are protected against short-term output shorts and have three progressive levels of thermal protection. Vantage products are built to the highest standards of quality and reliability.
