The split mode, pioneered by PS Engineering, is still available, but now  uses an intuitive push button selection. To make operation simpler, Com 1 priority is provided to the pilot, in split mode, with copilot selection of Com 2 or 3. The audio panel has concentric volume controls, one for intercom and one music volume. The PMA7000CD retains the dual independent music sources.  These can be paralleled to the PCD7100-R if desired. 

The telecommunications distribution in the PMA7000CD has also been improved by adding a full-duplex interface to aviation-standard impedance. This allows distribution of AirCell and Globalstar and Iridium conversations, providing private telephone calls by the pilot or copilot, or party line calls with the passengers and/or crew, using Com 3. The unit can easily be configured as either a Com 3 aviation or Com 3 AirCell interface at installation. The PMA7000CD now has four un-switched and un-muted inputs. This adds flexibility when installed with today's advanced warning systems, like Skywatch or TAWS.

An optional Digital Recorder is available. This is a continuous loop recorder that records the aircraft radio activity that is selected to be used for transmissions. Up to 1 minute/16 messages can be stored.
