Plena System Pre-amplifier | Installation and Operating Manual | Internal settings en | 11 2.5 Setting single and dual channel use The system pre-amplifier can be used with one booster amplifier for both music and calls ('1 channel use'). Any call will interrupt background music in all zones. It is also possible to use separate booster amplifiers, for music and calls ('2 channel use'). Now a call will not interrupt music in zones, not addressed by the call.
