Product Overview
The Model 381 On-Air Beltpack offers a unique combination of audio resources to directly support a complete broadcast "stand-up" on-air position.
Using Dante® audio-over-Ethernet technology, the unit provides main and talkback output channels, talent cue (IFB) input, and sidetone capabilities, as well as essential user controls in a compact, portable package.
The Model 381 is compatible with the Dante Domain Manager™ (DDM) software application and is AES67-compliant for direct integration into many contemporary networked audio applications.
