Introduction
The Extron MDA 3 Series of Mini Distribution Amplifiers
(MDAs) are a family of eight one-input, three-output, video and
audio distribution amplifiers. The MDA series distribution
amplifiers (DAs) split one composite video or S-video input
and/or audio input for output to multiple destinations with no
loss of signal quality. The MDA are members of the Extron
VersaTools™ line of basic distribution amplifiers, switchers, and
associated video accessories.
The MDAs distribute composite video, S-video (luminance (Y)
and chrominance (C)), and/or balanced or unbalanced audio on
captive screw connectors, or unbalanced audio on RCA
connectors, in the following combinations:
