The Model 5044 Matrix Mixer is designed to
provide the system designer, and audio contractor,
with a matrix mixer that provides adjustable output
levels for each line level input signal to each output.
The 5044 will accomodate up to 4 inputs and
provides 4 separate outputs each with it's own
custom signal mix.
Each input is balanced bridging transformer iso-
lated. Each output is low impedance transformer
isolated capable of driving loads as low as 600
ohms.
Each input level is adjustable from off to +25dBv to
each output, relative to the input signal level. Ad-
justment of an input level to any output will not effect
levels adjusted to other outputs.
Each output contains an externally controlled mute
switch for each input signal to allow mixes to be
changed from other control devices.
Typical mixes can include any or all input signals. The Model 5044 can also be used as a 4 channel line
amplifier.
Actual installations include such facilities as factories,
convention centers, racetracks, arenas, corporate
communication centers, airports, mass transit sys-
tems, and broadcast centers.
Every circuit in the Toolbox Series has been meticu-
lously engineered, to achieve maximum reliability.
The power supply section of all Tool Box Series
audio devices, incorporates a UL recognized power
transformer. By mounting the AC power transformer
outside of the audio chassis, the Toolbox Series
audio devices achieve the lowest possible hum speci-
fication. Fusing is accomplished thru the use of a
standard, easily available 3AG size Slo-Blo fuse,
with the fuseholder mounted on the rear of the
chassis. A ground lift switch is mounted on the rear
of the chassis, to provide additional installation flex-
ibility.
