The Twin Match from Henry Engineering, is a dual-stereo (four-channel) level and impedance matching interface. The unit allows users to correctly interface the stereo outputs of two "play only" consumer-level sources, with balanced "professional" +4dBm, 600Ω systems.
The interface is powered by an internal power supply, and provides four trim pots on the front panel for fine tuning individual channel levels. Adjustments can accommodate either +4dBm or +8dBm systems. All circuitry is active and direct coupled for exceptional sonic accuracy.
