Despite its tiny footprint, the XB-10 is packed with the kinds of specialized broadcast features that normally come at a much higher price. Radio-friendly tools include a telephone communication (telco) channel, mic channel ON switch sensing, stereo channel start/cue outputs for CD deck transport control and automatic muting of speaker outputs. A separate monitor mix can be created for operator and guest or presenter, and the operator can speak off-air to the studio or telephone callers using the 'Talk' feature. XB-10's preamps use low noise discrete transistor circuitry to achieve high gain and excellent linearity. Each mic channel comes equipped with our innovative CompACT compressor to keep the dynamic range of a presenter microphone under control. A variable limiter on the main output ensures that the final mix to air does not saturate expensive broadcast equipment. The plug-n-play USB connection can be used for VoIP telephone calls, recording program material, playing jingles and more. The XB-10 comes with a full duplex USB soundcard built-in and many useful routing options for recording and broadcast applications. It features a responsive 3-band, swept mid frequency EQ design which utilizes MusiQ with optimized slope for a variety of sources. A variable limiter ensures the level does not exceed a pre-defined level. Back panel option switches allow the limiter to be bypassed. A trim pot is used to vary the threshold and an LED on the front panel indicates when the limiter has triggered. The XB-10 features our ComPACT compressor, which combines both downward and upward compression with peak limiting. Low level signals are given a gain boost, mid level signals are mildly compressed with a soft knee response, and high level signals are limited.
