Henry Engineering- The Matchbox

This version is designed to be panel or rack mounted using the 2 keyholes in the back of the chassis.  They are light weight (1 lb) and small enough (6"x3.5"x2")  to be mounted to a rack rail or strut with Velcro or tie wraps. 

This model has a handy convenience outlet located on the top to ease the demand on the rack electrical strip.

There are level controls on the Studio Outputs.

Features and Specifications from Henry Engineering:

THE MATCHBOX  is an active interface amplifier that properly interfaces unbalanced “consumer” IHF-standard or Semi-Professional audio equipment with professional studio gear. THE MATCHBOX  is a bi-directional unit, with four independent amplifiers providing stereo input and output audio interface. Two amplifiers convert a stereo HI-Z unbalanced source to LO-Z balanced outputs at studio level. A second pair of amplifiers converts a stereo balanced studio line source to unbalanced compatible outputs. All four output levels are adjustable.

All circuitry is active and direct-coupled for absolute sonic transparency, making THE MATCHBOX  ideal for use with digital audio sources such as DAT recorders and computer-based digital sound editing systems.
