Two masters call and communicate with each assigned select
button. Transfer of a sub’s call to another on the other master is not
possible.
A call from TB-SE subs that are connected to two masters activates
tremolo tone at both masters. When the controlling TB-M is busy,
the other TB-M may pick up. In this case, the sub hears both
tremolo and busy tones.
