IR routing - discussed in ‘Typical System Configuration’ - is used to address specific centrally located

source components.

When several same brand and model source components are required in an installation, steps must be

taken to isolate the radiated IR from interfering with their discrete operation. This may be achieved

either by installing them in different cupboards or by using black IR blocking foam tape over the IR

emitters. The IR blocking foam tape is the preferred solution, since cupboard doors are often left

open.

Fig 3 shows a typical installation where several SAT receivers and tuners are required.

The dashed lines enclosing the source components represent IR isolation.

The second identical sources may be plugged into unpopulated AX4752 inputs, i.e. Tape, and Aux.

Axium controllers and sources may be re-labeled to identify their selection location.

Axium also offers an Emitter Expander ‘EX4’. This device simply provides connection for up to four

single or Dual IR emitters, and may be wired in parallel with the controller interface.
