The XB-142 offers a host of specialised broadcast features that normally come at a much higher price, including telephone communication (telco) channels, mic channel ON switch sensing, stereo channel start/cue outputs for playback device control, automatic muting of speaker outputs and much more.
XB-14-2 incorporates new features and styling based on feedback from the many broadcasters who have built their operations around the original XB-14.
With a wealth of routing options, dual stereo channels for up to 7 stereo sources, and the addition of a dedicated Audition bus, enhanced microphone preamps and stereo channel gain range,
XB-142 satisfies the demands of small radio and internet broadcasters as well as larger studios with multiple rooms. With no less than 27 logic I/O for remote control and 15 configuration switches, XB-142 is a highly flexible solution.
