Allen & Heath XB-14-2 Compact Broadcast Mixer

Perfect for a small radio station, online broadcasters, or large studios with multiple rooms, the Allen & Heath XB-14-2 Mixer delivers the specialized features you need in a compact build that easily fits into any existing setup. These features are ideal for broadcast needs, 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. From small radio stations to live-streaming to large TV studios, this mixer is the powerful, versatile tool for every broadcast application.

Select separate monitor mixes to assign to different mixer operators (perfect for a radio show host and guests, for example). Check levels and cue sources mid-broadcast. Use the Talk feature to continue the conversation off-air if you want. Remote control each channel’s mute function from the studio (ideal for studio-situated mute or “cough” switches). Whatever your project’s needs, the XB-14-2 makes it possible to pick and choose the sound you broadcast.

The XB-14-2 boasts several routing options for optimal flexibility, as well as 27 logic I/O for remote control and 15 configuration switches. It comes with dual stereo channels for up to 7 stereo sources, enhanced Duopre microphone preamps, and stereo channel gain range. Use the dedicated stereo audition bus for auditioning, or for off-air recording. Press the AUD button on the channels required to transfer your mix from the program feed over to the audition bus.

The XB-14-2 comes with a built-in full-duplex USB soundcard, along with myriad routing options that let you record and broadcast your mix. The XB-14-2 includes 2 Telco channels. These channels offer selectable clean-feed output (LR PGM, Aux, or Audition bus). They also include variable high-pass and low-pass filters that help reduce the frequency range when used with a telephone caller. Finally, the XB-14-2’s Telco channels come with a convenient TALK button.
