I plan to combine the MK163 and the MK161 in the same case to be able to switch a power amplifier on/off in addition to controlling the input volume to that power amplifier. Is it possible to connect the IR sensor of the MK161 to both units (the MK161 and the MK163) in order to simplify the design of the front panel (one IR inlet instead of two)? I intend to use a short shielded connection between the two circuit boards.
You can use the same IR receiver for both units.
