IR EMITTERS
The PR-4Zi has seven IR outputs:
Source 1–6 and Common. Source
1–6 outputs are source-specific and
provide IR signals only to the
selected source; the Common out-
put provides IR signals to all
sources.
Source-specific IR outputs (Figure
17) are useful when a system has
two or more of the same model
source component, allowing you to
target the IR commands to each
individual component.
To connect multiple emitters to the
Common IR output, use the
Russound 857 connecting block
and a 1/8-inch (3.5mm), 2-conduc-
tor (mono) phone plug as shown in
Figure 18. Connect common (COM)
IR output to “IR INPUT” on the 857
connecting block.
