Henry Engineering USB Matchbox-II



Bi-Directional Interface Amplifier w/ USB


The Henry Engineering USB Matchbox II is a professional USB-to-XLR multi-mode stereo audio codec offering superb audio performance with the ease of USB connectivity. Ideal for any situation where computer audio needs to interface with a professional analog or digital audio system, the USB Matchbox II provides balanced analog inputs and outputs, an AES/EBU digital output, plus a Headphone output for monitoring.

The heart of the USB Matchbox II is Burr Brown's new generation phase coherent Delta Sigma 8X Oversampled codec with SpAct audio clock recovery architecture. The codec's superb performance is further enhanced with proprietary L/C pre-filtering and edge-of-the-art analog circuitry, fine-tuned to eliminate the transient intermodulation products that plague the typical sound card.

The USB Matchbox II's built-in AC power supply allows operation at true _professional levels with liberal headroom. MS-Windows, Mac, and Linux platforms are supported; no special driver or software is needed. The USB Matchbox II will operate with virtually any audio editing, recording, or broadcast automation software that supports a USB sound device at sample rates up to 48 kHz and 16 bit resolution.

The USB Matchbox II provides the quality and facilities that professional users require. Its dual-PLL asynchronous design permits simultaneous record and playback at different sample rates. Front panel trimmers allow precise adjustment of input and output levels. A high performance Headphone output is provided for critical monitoring. Rear panel connections include XLRs for balanced analog I/O and the AES/EBU digital output. The steel chassis provides effective RF shielding.

The USB Matchbox II 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. The unit is powered with an internal AC power supply.
