universal power combiner
The universal power combiner “UPC” is designed especially for the sound crew – it is a gadget designed especially for devices utilizing the 4pin Hirose HS10A plug such as (but not limited to) the SoundDevices® mixers and preamplifiers.
The UPC allows two batteries to power one target device, and it will automatically switch between the inputs allowing the user to “hot-swap” a drained battery during recording without the fear of shutting down.
It comes with two LED indicators showing which of the two inputs are currently feeding the target device.
When both battery inputs reach the same voltage, they will both share the output load uniformly.
If any of the two inputs fall below 11.5V (considered low voltage) then the LED color for that input will switch from GREEN to RED.
