IR Remote Controle Receiver

With many audio systems consisting of separate units, you’ll often find that due to economic reasons only the amplifier has a remote control receiver module. The control signals are then sent to the other units using patch cables. The tuner and CD player, for example, won’t have a built-in receiver module. When the tuner from such a system is bought separately it can therefore not be used directly with a remote control, which is a big disadvantage in practice.
