Does pre-emphasis and deemphasis work with rxchannel=Voter?

I’ve had some reports saying the audio was lower on a couple repeaters we now that we are using a different allstar server. Not sure how that could happen with all the same settings.

Thanks

Yep, it’s a bit convoluted the way de/emphasis is set but it’s well documented on our WiKi. The settings you need are in the RTCM itself, not chan\_voter. Therefore it is possible to individually set de/emphasis per RTCM.
