But should again high-frequency oscillation occur, the speakers are switched off
again and the LEDs (17) and (18) lights on again.
In general, the oscillation disappears by using a different speaker cable.
But it wants to work with the original cable, please use a RC circuit (Snubber)
connected direct at the speaker terminals. This can help to prevent oscillating at the
power stage.

This LED is lit when the speaker relays are switched off. The speaker relays are
switched off when the protection mechanisms mentioned above, but can also be

case, so you get a message on the display (5).
Epilog
Two analogue input modules the standard feature of the .
