The XB-10 by Allen & Heath is a compact broadcast mixer designed for self-operated broadcast applications in small radio and internet studios, as well as larger facilities with multiple rooms.
It offers a host of features such as a telephone-communication (Telco) channel, ON switch logic for automatic muting of speaker outputs, start/cue outputs for CD deck-transport control, separate headphone mix & output for guests, built-in mic compressors, output limiter, and more.
The XB-10 audio circuitry employs three mic/line channels equipped with high-gain preamps, 3-band EQs to help cut sibilance & lower popping noise, and 2-band EQs for use with music. Each mic pre is equipped with a compressor, and a limiter on the main output ensures that the final mix does not exceed predetermined level.
The full-duplex USB sound card offers playback and record to & from a computer as well as voice over IP (VoIP), and it's compliant with Mac & Windows core audio drivers.
