The Allen & Heath XB-14 Radio Broadcast Mixer is designed for a broad range of applications from small radio or internet broadcast studios, to larger studios with multiple rooms, hospital radio, university radio and community radio. The XB-14 is equipped with a wealth of features specifically for broadcasters, including telephone communication modules for telephone callers, mic fader start sensing for external connection and internal automatic muting of the speaker outputs, stereo channel start/cue outputs for CD deck transport control, separate headphones mix and outputs for guests, an audition bus, and much more.
The XB-14 has four mic/line channels, four stereo channels and two Telco telephone communication channels, with 3-band EQ on the mono channels and 2-band EQ on the Telco and stereo channels. The mono mic/line channels have fader start logic switching, which reportedly enables them to control external equipment or automatically mute the speaker outputs to prevent acoustic feedback in localized or self-operated applications. Individual channels can also be remotely muted via the 15-way D connector. The stereo channels have "start and cue" logic outputs to connect to external equipment such as CD players. The Telco channels have a clean feed comms facility for easy communication between the presenter and the cued caller.
There is a single aux bus for external effects processing, recording or auditioning, and a separate "Mix B" stereo bus for recording an independent mix to the main program mix, or creating a clean feed source with selected channels. The XB-14 also has USB connectivity for interfacing with PC/MAC to access computer-based audio files and content management systems, while simultaneously outputting program, aux or Mix B feeds in digital format.
Separate headphone monitor mixes can be created for operator, presenter or guests, so the engineer can check levels and cue sources while the presenter or guest can listen to a different source. The engineer/producer can also communicate to the studio using the "Talk" feature, or off-air to telephone callers. There is a facility for remote control of channel mutes from the studio using the remote interface connectors, which is targeted for studio-situated "cough" mute switches.
