1. Power LED - This green LED illuminates when AC power is supplied to the
V-10.
2. DC Power Output Jacks 1-4 - These four outputs provide fixed 9VDC
power. The maximum allowable current draw on each of these outputs is
150mA (see "Specifications").
3. DC Power Output Jacks 5-6 - These two outputs provide independently
selectable 9VDC or 12VDC power. These outputs are mergable, allowing
for connection of "power hungry" pedals which require more current. The
maximum allowable current draw on each of these outputs is 200mA
(unmerged). When merged, these outputs can provide a shared total of
400mA of available current (see "Specifications"). Note that even when these
outputs are merged, they can still be independently set to 9VDC or 12VDC.
4. Merge Status LED 5-6 - This yellow LED indicates the merge status of
outputs 5 and 6, illuminating when these outputs are merged.
