Once you have all of the parameters to your liking,
first turn off any connected equipment
, and then disconnect
the USB cable from the miniDSP 2x4 or kit board.
To be able to continue to operate the miniDSP in offline mode (without the computer connected), you will need
to provide an alternate power source. There are two options:
•
Connect the USB cable to a 5VDC USB charger. The 2x4 or kit board requires 150 mA of current, so almost
any USB charger should be adequate.
•
Connect an auxiliary DC power supply to the 2.1mm DC power connector. The power supply voltage can be
in the range of 4.5 to 24 VDC, enabling use of a wide range of power sources.
The DC power connector must have the positive voltage on the center pin. Be sure to check this before
connecting the power supply, as otherwise your unit may be damaged.
Note
: Prior to Rev3 of the miniDSP circuit board (released in June 2014), auxiliary power for the miniDSP 2x4 and
miniDSP kit is provided via a Phoenix connector with screw terminals instead of a 2.1mm DC connector. If you
have an older version of the board, please refer to the older manuals
or
for the correct power supply connection.
