MDA-26 ™ /MDA-16 ™
DISTRIBUTION AMPLIFIERS
The Oxmoor MDA-16 and MDA-26
are high-performance audio buffer/
distribution amplifiers for profes-
sional applications. The MDA-16
enables a single input to be distrib-
uted among six electrically-isolated
output channels. The MDA-26 adds
flexibility with two inputs accept-
ing either stereo or two mono
sources. Using internal jumpers,
each of the MDA-26 outputs can be
assigned to either or both inputs.
The MDA-26 permits a wide vari-
ety of signal routing and level
matching combinations. Example:
two one-by-three Distribution Am-
plifiers or stereo in with stereo out
and four mono sum outs.
Each model allows front-panel in-
put gain trim adjustment of
±
15 dB
to compensate for varying input
signal levels. Outputs also feature
independently adjustable gain over
a
±
15 dB range and can deliver a
maximum level of +24 dBm, 20Hz
to 20kHz, with greater than 80dB of
isolation between channels.
Inputs and outputs are electroni-
cally balanced and feature standard
3-pin XLR-type connectors. The in-
put circuits accommodate up to +24
dBu signal levels, and incorporate
RF suppression to preserve signal
integrity in the presence of radio-
frequency interference. Each out-

put driver has an internal jumper
that allows configuring for balanced
or unbalanced operation. Optional
output transformers are available
by ordering either the MDA-16T or
MDA-26T.
Both models are capable of match-
ing disparate signal levels, allow-
ing hi-fi and professional line-level
signals to be freely inter-mixed with-
out additional interfaces. Their im-
pressive audio specifications, and
compact, rugged construction make
them ideally suited to recording and
broadcast applications.
Housed in 1U EIA rack-mountable
enclosures and UL Listed, the
MDA-16 and MDA-26 are the reli-
able and dependable solutions to
whatever audio distribution prob-
lems you may have.
