JL FMGS new intercom module

[Fritz]

Some comprehension questions about the new intercom module. Is it correct that the headset and the microphone have to connect to a sound card
and the volume can be controlled with a potentiometer via interface card like BU0836A?
I have isolated the environment sound and the ATC in my system to hear only the ATC in the headphone.
Can I select the appropriate soundcard in the Intercom module?

Best regards
Fritz

NOt sure what you mean?

Thanks for the answers.

Here is a pic with the setting I meant.

If I would control the volume with a potentiometer, then the volume is only controlled on the headphones
or also the environment sound?

My intercom is not able to interfacewith P3D sounds...
THe only ATC sound you can play must come themselves from a sound card input.
In your case, if you want to play the P3D ATC voice, there is a possibility, which is to use a virtual audio driver, which will create a fake speaker you declare in P3D, and a fake microphone that you'll delcare in the intercom (in the external radio part of the intercom).

I haven't had time to look at the intercom in great detail but does anyone know if a hardware intercom system would be compatible, or would there still be a need if all functions can be emulated with software?

For example, volume on the ACP can now be wired and controlled with a pot.

Is sidetone possible, and can other headsets and mics be wired in (would like to start with 2, and expand to 4)?

I dont think an hardware intercom is compatible, as they do all the audio routing internally with analog to analog components, which is good for latency and audio quality, but makes it harder to interface with third party software. Maybe some volume control could be possible, depends how the intercom board is done.

For now there is no sidetone, but I can add it easily if needed... I have no idea if the real one has a sidetone feature or not??
Currently, 3 positions can be used (CPT/FO/jumpseat) as on the real aircraft (there are 3 ACPs only), with the corresponding in/outs (the jumpseat does not have a speaker for instance...). On the real A/C, there can be a fourth station, but I think it is in fact the same wires as the jumpseat, with only an headset, using the same ACP.

Thank you for the insight JL.

I have 2 Telex 750 XLR 5 pin which I would like to use with the sim. I will attempt to find a way to interface to a sound card so your software can be used.

I am pretty sure there are hardware interfaces for those from XLR to jack for only a few bucks.

Hi Ben and JL, when INT is selected, we always hear our voice (sidetone) as confirmed by an A321 pilot.

The ones I have been looking at cost over a hundred dollars! Apparently you can't just wire it into the jack because of impedance. https://www.flightsounds.com/

masterp: thanks for the update and confirmation.
