The PS 61 or PS 81 receives its supply voltage through the antenna cables from the receivers connected to the PS 61 or 81. Alternatively, you can connect a central power supply to
the DC input jack on the PS 61 or PS 81. With this setup, the PS 61 or PS 81 and the receivers connected to it will be powered through the antenna cables. This is the best way to power a
multichannel system because it makes wiring a lot easier and clearer.
