The only differences are the two connectors on the top and bottom of the front of the tester.
The AudioJoG Pro 8 has a pair of Speakon NL4's and Speakon NL8's.
The AudioJoG Pro 8 power has a Powercon inlet and outlet and a pair of Speakon NL8's.
The AudioJoG Pro 8 mobile has a Powercon inlet and outlet and a pair of Speakon NL4's.
All the other connectors are the same and the testers operation is identical.
