SL-12 - Connecting the SL-12
4.1 Using the RC-4 IR transmitter
You can use up to two optional RC-4 IR transmitters as auxiliary control panels
and initiate configured control triggers—refer to the K-Config guide—via the built
in IR receiver on the front panel, and/or via the optional external IR receiver
(C- A35M/IRR) that exists in several cable lengths.
4.2 IR Input Functionality
The SL-12 front panel includes one built-in receiver and two IR inputs on 3.5mm
jacks (shown in Figure 3) for control via the RC-4.
Figure 3: SL-12 IR Inputs
These three IR inputs can be set up differently, as shown in the following table:
None of the external IR receivers are connected:
RC-4 controls the unit through the
built-in receiver
Define IR-1 – RC-4 as the
auxiliary device and set the
triggers
An external IR receiver is connected to IR Input 1:
One RC-4 controls the unit through
the built-in receiver and a second
RC-4 unit controls the unit through
the IR Input 1 external IR receiver:
Define IR-2 – RC-4 as the
auxiliary device for the built-in
receiver and set the triggers
Define IR-1 – RC-4 as the
auxiliary device for the
external IR receiver
connected to IR INPUT 1 and
set the triggers
