PORTAMATCHtm

BATTERY OPERATED STEREO LEVEL & IMPEDANCE INTERFACE

Product Description

Portamatch is the battery-operated version of The Matchbox II. It operates on two 9-volt batteries, and is ideal for use whenever AC power is not available. Portamatch is the ideal way to correctly interconnect “consumer” or semi-pro equipment with professional gear. Portamatch 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 accomodate a wide range of operating levels. Portamatch 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 Portamatch ideal for use with digital editors, DAT recorders, and other digital audio sources.
