The Beatrice P2 is a two channel handset.
The user of the handset on the P2 unit can listen to two audio feeds from the network and send two audio channels out onto the network. Depending upon how the Dante® network has been routed, the incoming audio circuits and outgoing circuits can be different locations and the outgoing circuits can be routed to multiple locations.
Audio to the handset from the two network sources is routed to the telephone's earpiece only when the handset is off the hook. When the handset is picked up (off hook), the handset's microphone is turned on and two switches allow the operater to route the handset's microphone to one or other (or both) of the outgoing network audio channels.
The Beatrice P2 unit is fully compatible with other manufacturers' equipment using the Dante® protocol.
