Low volume on Radio FX - volume override channel plugin ?

[JEJKU]

Hello. I am using Radio FX plugin and the volume is really low, even when I have all users in channel (1 specific room) +10 dBa.
Is there any plugin to TURN TO VOL UP on that 1 channel, where plugin is ON?
Or any other suggestions?

Thanks for help.

Am I able to boost volume of all users in 1 channel ?
Only that one? About 100% ? Cause using radio FX is very LOW sound volume.
Thanks for help.
Any plugin or ideas are welcome.
