The U.S.D.A. 2x4 from Henry Engineering is a mini distribution amplifier for combining or splitting audio signals. In stereo mode, it acts as a one-input, two-output distribution amplifier. In mono mode, it is a two-input, four-output distributor. Front-panel switches let you select stereo or mono operation. The U.S.D.A. 2x4 also produces simultaneous mono and stereo outputs from a stereo source.
All I/Os have plug-in Euroblock connectors and support balanced or unbalanced connections. Each output has an adjustable level with a 26 dB range. The unit has transformerless circuitry and is direct-coupled for accurate sound. The 1/3 rack-space size makes it easy to rack or wallmount the unit. It is built with an internal AC power supply.
