Henry Engineering TWINMATCH Dual-stereo (4-channel) Level and Impedance Converter

TwinMatch is a dual-stereo (4-channel) level and impedance converter that interfaces two consumer stereo outputs with professional balanced equipment.

TwinMatch is ideal for use with a pair of stereo CD players or other play only sources. The unit accepts four channels (2 stereo pairs) of -10 dBv unbalanced audio and converts to professional 600 ohm balanced lines. The gain is adjustable to accommodate either +4 or +8 dBm systems.

All circuitry is direct-coupled and transformerless for sonic transparency, making TwinMatch ideal for digital sources. Unbalanced inputs are on gold-plated RCA jacks; balanced outputs are via XLR connectors.
TwinMatch is 1/3 rack width and can be mounted in an optional rack shelf, or wall mounted with optional wall/cabinet mounting brackets. TwinMatch is powered by an internal AC power supply.
