Description

MATCHBOX HD

 

The rack-mountable Matchbox HD is the new high performance version of the industry’s most popular analog level and impedance converter. Matchbox HD offers a true 100 dB S/N ratio, with 22 dB of headroom to yield 122 dB of dynamic range. It is the very best way to interface “consumer” or semi-pro equipment with professional audio gear.

The Matchbox HD is a bi-directional unit, employing four independent amplifiers to convert stereo inputs and outputs from unbalanced -10 dBv levels to +4 dBm balanced 600 ohm lines. All four outputs can be adjusted to accommodate a wide range of operating levels.

The Matchbox HD also features a special HI GAIN mode to properly match the low-level unbalanced outputs of computer sound cards. The unit’s direct-coupled circuitry and exceptional dynamic range provide absolute sonic transparency, making Matchbox HD ideal for use with digital editors, DAT recorders, and other digital audio sources.

The Matchbox HD has an internal AC power supply. It is 1/3 rack width and can be mounted using the optional rack shelf, or wall mounted with optional wall/cabinet mounting brackets.
