has so many uses. It's a stereo distribution amplifier

Product 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.
