Can I boost up 1 channel volume for all users (so I can hear them better) with this?

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.

Is there any plugin to TURN TO VOL UP on that 1 channel, where plugin...
