Turning on/off engine sound
The sound module can only play an engine sound, if it has been switched on before.
There are different ways to switch on the engine sound:
Using the switching-input X1/3 to switch on engine sound:
If the input X1/3 is tied to the negative pole (ground), the engine sound is switched
on. If this input is open, the engine sound is turned off.
There are several possibilities, how to set the input to the negative pole:
With a simple wire: Just connect the negative pole of the battery with the
switching input X1/3 of the sound module using a wire. The engine sound is
switched on as soon as the sound module is connected to power. The
disadvantage of this setup is that the engine sound cannot be turned off,
except you switch off the complete supply voltage of the sound module.
This is an easy way to test the sound module for the first time.
Instead of the wire, of course you can use a simple switch between X1/3 and
the negative pole, in order to switch the engine sound on or off. The
disadvantage is, that it is not possible to switch the sound on or off by the
remote control.
If you replace the switch with a switching unit (e.g. Multiswitch), you can
switch the sound via the remote control. It is important that the switching
output of the switching unit is negative switched (usually they are)!
Using a proportional channel (X2/2 - X2/4) to switch on engine sound:
If you have a joystick/slider/switch/rotary switch left, you can use it to switch the
engine sound on or off. Therefore the corresponding receiver ouput must be
connected to the corresponding proportional channel of the sound module with a
servo patch cable.
The desired proportional channel must be configured in the Sound-Teacher. There
are 4 areas “A, B, C and D” (see page 35) and one area must be mapped to the
function “Engine sound on/off“. If the corresponding proportional channel is brought
in this area, the engine sound is switched on or off.
This possibility is only available in digital- or mix mode.
Using the Nautic-mode on proportional channel #3 (X2/3) to switch on engine
sound:
If you have a Nautic swiching unit installed in your receiver, you can use the Sound-
Teacher to add the function “engine sound on/off" to a Nautic switch to turn the
engine sound on or off with the selected switch.
This possibility is only available in digital- or mix mode.
