The Audix DN43 interface is a designed for AES67 Ethernet-powered installed audio networks. Like its larger brother, Audix's DN4 interface, the DN43 boasts high quality audio and a range of essential installed microphone functions such as on-off contact closure and LED status indicators, all available through a single CAT5, 6 or 7 cable featuring RJ45 connectors at both the interface and microphone end.

The DN4 differs slightly from the DN43 in that a single input designed specifically for the Audix M3 is available offering perfectly tailored compatibility for M3 users. The additional RJ45 microphone input meanwhile is compatible with any single-element Audix microphone.

Two 5v logic outputs are available per port with source/sink capabilities for LEDs controlled by networked DSPs. Low and high pass filter setting are also available on a channel-by-channel basis, along with eight selectable gain levels.

All DN43 channel settings can be controlled remotely using Audix’s proprietary software app.
