Henry Engineering USB Matchbox II USB to XLR Digital Interface

The Henry Engineering USB Matchbox is a professional USB-to-XLR bi-directional stereo audio codec. It provides unparalleled audio performance with the ease of USB connectivity in any application where digital audio from a computer needs to interface with a professional analog audio system. The USB Matchbox is USB powered, and solves the myriad of problems caused by using common sound cards in broadcast and professional audio environments.

The USB Matchbox provides the quality that professional users require. Its dual-PLL asynchronous design permits simultaneous record and playback. Front panel controls allow precise adjustment of input Level and L/R Balance trim. Output levels are calibrated with recessed trimmers. Rear panel connections include XLRs for balanced analog I/O, Auxiliary unbalanced line inputs, and outputs for amplified speakers. The Speaker output can be muted with an external contact closure via the Mute jack. The steel chassis provides effective RF shielding. All ICs that connect to the "outside world" are mounted in sockets.

The USB Matchbox is 1/3 rack width, and can be rack-mounted using the optional rack-mount shelf, or cabinet or wall mounted using optional cabinet/wall mounting brackets. Also available: USB Match Plus: Identical to the USB Matchbox, but with the addition of peak- reading level meters and a high-performance headphone amplifier.
