2.4.1.
Type of Power Supply ( XLR 5xxA, XLR 5xx )
The XLR 5xxA uses AC power. C100 ~ +240V AC to the connector of XLR 5xxA using a
power cord enables it power the unit on. The XLR 5xx uses a DC adapter which supplies 5V DC 3A. The
difference in power inputs makes the two products easily identifiable.
