D3 Tips & Tricks:
MS stereo:
In the D3 MS stereo is available at the 'touch of a button on the screen'.
This mid / side stereo is a form of intensity stereo using a normal (cardioid or omni) microphone for the 'M' channel in combination with a bipolar (figure of 8) microphone for the 'S' channel.
In order to use this setup you needed a special decoder or 3 channels in a mixing desk were the 'S' microphone is connector to 2 microphone inputs. By inverting the phase of one of the 'S' channels and panning both 'S' channels to L and R a stereo signal is made as Left = M + S and Right is M - S.
In the D3 the microphone input is fed to both L and R channel of the system. Each input has the possibility to invert the phase of L and R separately. By just inverting the phase of the R channel in the path of the 'S' microphone you can archive the same effect.

From the main screen select: System / GPIO / GPI shape:
Select GPI 2 (in this example) to be inverted.
Store the settings.
Upon closing the fader the channel will now switch to PFL automatically.
In most cases you can still wire a faderstart to this GPO in parallel.

Auto Pre Fade Listening:
In addition to the 'signal present' indication on a channel in some situations it may be helpful to also switch an input channel to pfl automatically when closing the fader.
This can be done by soldering a link between one of the GPI's and a GPO on the 25 pin D-type connector. In the example below GPI 2 and GPO 2 are used. See the manual for the pinout diagram.
On the input GPIO settings of the used channel set 'Remote PFL' GPI and 'Fader out' GPO accordingly:

Just connect the 'M' microphone to one channel and the 'S' microphone to another channel. For the 'M' channel do not invert the phase, leave all settings standard. For the 'S' channel make the settings as in the example above: Make sure the ‘Config’ is 'Stereo' and select the INV R button to invert the right channel. As you will probably use condenser microphones do not forget to switch on the Phantom power supply.

Cough function:
In radio the 'cough' function is a button used by a presenter to mute the microphone signal in case he or she has to cough and doesn't want this to be audible for the listeners. In most cases this button is also used to contact the technician behind the mixing desk again without the listeners hearing this. This is archived by muting the microphone signal for the output and at the same time switching on the pre fade listening of the channel.

In the D3 you can simply wire a switch to one of the GPI’s (number 2 in the example) and assigning this switch to the channel mute and remote pfl simultaneously.
