There is no sound

Check to make sure that each speaker has been properly connected to the
speaker output jacks on the rear panel of the DCP501.

If the front panel displays O V E R L O A D , one of two things has happened:
1 If the DCP501 detects the speakers have a short circuit, it shuts down
the amplifiers. Switch the DCP501 off, remove the short circuit, and turn
the DCP501 back on. The DCP501 should now work as normal. If
O V E R L O A D is still displayed, a short circuit condition remains.
2 If the maximum amplifier output power is exceeded, the DCP501 shuts
down the amplifiers. Turn down the volume a little and switch the
DCP501 off and then switch the DCP501 back on and the DCP501
should now work as normal. If O V E R L O A D is still displayed, turn the
volume down some more.
