DESCRIPTION:

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.

Mic/Line Pre-amps

The XB-14’s two stage pre-amp design, offers an expansive and controlled gain range (69dB). Most of the gain comes from the first stage, so unwanted noise is kept to a minimum, and the second stage is padless, with line level signals simply plugged in using the input jack socket, which means lower noise when using the line input.

 

EQ

The XB-14 is equipped with a 3-band equaliser circuit on each mono input and a 2-band EQ on the Telco and stereo channels. The frequency and response of each has been carefully chosen to give the maximum performance when using the EQ on a variety of sources.

 

AUX Bus and MIX B stereo Bus

XB-14 has a single Auxiliary bus that can be used for external processing, effects, recording or auditioning. A separate stereo mix bus is provided for recording an independent mix to the main program mix, or creating a clean feed source with selected channels.

 

Remote Control

The mono mic/line channels have fader start logic switching, enabling them to control external equipment or automatically mute the speaker outputs to prevent acoustic feedback in localised or self operated applications. The stereo channels have ‘start & cue’ logic outputs to connect to external equipment such as CD players. There are also options to mute the mono inputs remotely using an external “cough” switch or similar.

 

USB

Getting audio to and from a computer easily is essential for music and broadcast production, so the XB-14 is super-flexible and super-easy! Just plug in a USB lead and select the USB routing to enable quality audio to and from your PC or Mac.

 

Self or Producer Operated

Separate monitor mixes can be created for operator, guests or presenter so the engineer can check levels and cue sources while the presenter or guest can listen to a different source. The engineer/producer can communicate to the studio using the ‘Talk’ feature, or off-air to telephone callers.
