RMX-44 & RMX-62 INTRODUCTION
The RMX-44 and RMX-62 Mixing Matrixes may
be used as buffer/mixer/distribution amplifiers.
The RMX-44 offers a four-in by four-out config-
uration while the RMX-62 is a six-in by two-out
system. Each compact unit is housed in a 1U,
rackmount chassis and weighs just under 8.5
pounds.
The RMX-44 and RMX-62 are intended for use in
sound reinforcement, permanent installations,
playback, and other audio systems requiring
high-quality operation with flexible audio rout-
ing from remote locations.
The RMX-44 unit allows, for example, stereo com-
ponents and their sum to be assigned to separate
output lines. High and low input and output lev-
els can also be freely intermixed without addi-
tional hardware, facilitating such common con-
version tasks as interfacing hi-fi equipment with
professional audio systems.
The RMX-44 and RMX-62 input stages are elec-
tronically balanced and fitted with standard 3-pin,
XLR-type connectors. Front-panel gain trimmers
enable the installer to compensate for various in-
put signal levels. RF suppression circuitry safe-
guards against radio-frequency interference in
hostile environments.
For enhanced flexibility on both units, each out-
put driver can be set for balanced or unbalanced
operation using internal jumpers. The output
stages will deliver a +24 dBm maximum output
level, with overall 20Hz to 20 kHz frequency re-
sponse, +0, -0.3 dB.
Both devices are also available with optional out-
put transformers. Designate Model RMX-44T or
Model RMX-62T. Transformer equipped version
may be operated Balanced or Unbalanced with-
out any change to the internal jumpers.
Designed to satisfy exacting professional stan-
dards, the RMX-44 and RMX-62 offer excellent
performance in highly dependable packages.
Their impressive audio specifications are ideally
suited to recording and broadcast applications,
yet their rugged chassis and exceptional immu-
nity to environmental stress make them an ideal
choice for demanding road work and commer-
cial installations.
