Description
U.S.D.A. (Utility Summing & Distribution Amplifier) is a unique 2x4 mini-DA that can be used to combine or split audio signals for distribution. It can be used as a 1x4 or 2x4 DA in stereo or mono.
There are 2 inputs (1 stereo pair) and 4 outputs (2 stereo pairs). Front panel "Stereo/Mono" switches select either a stereo or mono output from each output pair. USDA can produce both stereo and mono outputs simultaneously from a stereo source. Inputs and outputs can be operated either balanced or unbalanced. The audio level of each output can be adjusted over a 26db range. All circuitry is transformerless and direct-coupled for sonic accuracy.
Connections are via plug-in euroblock connectors. USDA 2X4 is 1/3 rack width and can be mounted in an optional rack shelf, or wall mounted with optional wall/cabinet mounting brackets. USDA 2X4 is powered by an internal AC power supply.
