The Triax Matrices enables the end users to control the source equipment whilst in the main viewing area. This feature is
possible by installing an IR receiver connected to the IR in port on the HRX 1LP4K receiver. Using the standard remote
control for the Source device, direct the remote at the receiver which must be in-line of sight to ensure that it picks up the
IR commands.
The IR commands are modulated on to the CAT cable infrastructure and demodulated at the matrix and converted back to
IR signals IR Out port, these commands are then blaster back via the transmitter to the source device.
