About the IRL 20
The Extron IRL 20 is a hardwired infrared (IR) signal receiver
for use with Extron IR remote controls and an Extron
MediaLink
™
Controller (MLC), MediaLink Switcher, System 5 IP
Switcher, or AVT 100. The IRL 20 receives a signal via its front
panel from an Extron IR remote operating at 38 kHz. It can also
receive IR input via an optional Extron IR Sensor, which is
smaller and less visible than the IRL 20. It outputs the
modulated IR signal via an IR Emitter or the IR Link or CM/IR/
SCP port of a device mentioned above, allowing that device to
be mounted out of sight in a rack or furniture.
Features
Compactness and flexibility — The IRL 20’s small enclosure
can be secured to any surface without having to cut any
holes in furniture or walls. This allows for a wide range
of mounting locations.
