IRX Wallmount Amplifier/IR Receiver

When an Armstrong Sound Panel is used, the ampli

fi

 er is an integral part. It supplies

power to the IR receiver and any Outreach points as well as providing audio 
inputs and controls; please refer to IAPA section for details on connection
and commissioning.
However, where surface-mount speakers (Pack F & G) are used, the IRX Wallmount 
Ampli

fi

 er/IR Receiver is provided as part of the kit. It should be installed adjacent to the 

whiteboard (or front of the classroom) at a height convenient to allow adjustment of the 
level controls. The associated Outreach Plate should also be installed close by.
Please refer to page 12 for details of IRX installation and commissioning.

Safety Note

It is most important that the supplied safety cables and security clips are used and 

fi

 tted 

correctly on each loudspeaker as part of the installation.
