D500X
The D500X Mk II is as easy to use and provides the same features as the classic D500X, with the following exceptions:*It does not include an internal microphone. Instead it ships with an external microphone which is either directly connected to the microphone jack or through an extension cable (sold separately). The microphone jack is an XLR type so no adapter cable is required.*It is powered by 4 C type batteries which last roughly three times longer than the AA batteries used in the classic D500X.*The jack for external power is a standard 2.5 mm DC power jack for easy connection.
