UDM230 Main Module
SIXPACK
RECHARGEABLE
BATTERIES
When used with the Sixpack multicoupler, additional
power supply features are added. A relay automatically
switches to take power from an external power source
instead of the Sixpack battery pack when DC is pres­
ent at Pin 4 of the XLR connector. This allows Sixpack
battery pack to serve as a backup for the external DC
power source.
