MIXING MATRIX SYSTEMS

The Oxmoor RMX-44™ and
RMX-62™ Mixing Matrix Systems
offer a unique, high-quality solu­tion for many audio routing and
combining applications.

For enhanced flexibility, all in­put/output assignments can be
controlled remotely via switch clo­sures. Now you can alter and
modify signal routing within a
complex sound system from a cen­tral location.

Configured as a 1U rack-mount
device, the RMX-44 is a four-in­put/four-output combination sig­nal buffer, mixer and distribution
amplifier. All inputs can be indi­vidually adjusted in level, and
combined together to feed any or
all outputs. The RMX-62 is virtu-

simultaneous stereo and mono
feeds from different input assign-

ments.
ally identical to the RMX-44 ex­cept that it offers six inputs and
two outputs.

High and low input/output lev-

els can also be freely intermixed,

allowing semi-pro and profes­Potential applications include
combining four or six inputs for
zone mixing, and providing

Rear-panel, electronically bal­anced inputs and outputs use re­liable XLR connectors. The RMX­44T and the RMX-62T provide
output isolation transformers.
While the nominal input signal
level range is -10 to +8 dBu, the
units are capable of handling +24
dBu signal levels. Each output can
be unbalanced independently
using internal jumpers.

A rear-panel, 25-pin Control Port
provides individual access to
each of the input/output matrix
assignment crosspoints. All that
is required to route any input to a
chosen output is a switch closure.

Like all Oxmoor products, the
RMX-44 and RMX-62 are built for
enhanced reliability. The bottom
line is simple: both the RMX-44
and RMX-62 pack a great deal of
operational flexibility into a small
amount of space.
