Advanced IR Control
IR routing – discussed in “Typical System Configuration” on page 9 – 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.
