Power Options
Connect power through either J8 (4) if using a power
adapter or J6 (5) if using a Dayton Audio battery
board.
a.
It is recommended to use a power supply of
at least 12V but less than or equal to 24V.
The higher the voltage input (with adequate
current capabilities), the more power the
amplifier can supply to your speakers. Power
supplies out of this range can damage the
amplifier.
b.
The KABD-250/230 does not have a built-in
battery charging circuit, so
a battery board
such as LBB-3v2 (12V) or LBB-5Sv2 (21V)
that has a charging protection circuit built
in is required to use the amplifier with
batteries
. If you are familiar with the KAB
series from Dayton Audio, these boards
include a battery charging circuit on the
amplifier itself, thus the battery boards do
not need to contain a charging circuit, but
the KABD series need this circuit on the
battery board itself.
c.
Connect a 2.5mm or 2.1mm DC jack to J9 to
allow a variety of power supplies to be
attached to the KABD-250.
3.
Bluetooth Pairing Switch
A Bluetooth pairing switch (green) that comes in the
box can be added to the KABD by attaching its 2 pin
connector to the corresponding port (J3). See the
quick start diagram or look for the “BT Pair” port as
labelled on the underside of the board.
Holding this button down for about a second will allow
a new device to be paired to the KABD and will
disconnect the old device. Do not hold this button for
longer than 5 seconds. Use this button if you are not
seeing “DAKAB” in your
Bluetooth list.
Note:
Only use momentary switches for the BT pairing
port.
