Input Jack
(Optional)
A 3.5mm jack comes included in the functional cable
pack with attached 5 pin connector, which can be
plugged into J9 to function as a line input for external
audio sources.
This wiring harness could be modified by snipping off
the 3.5mm jack, and soldering stereo RCA jacks to the
cables according to the pinout on the back of the
board or on the chart to the right.
7.
Standby Switch
(Optional)
Included in the functional cable kit is a switch wired to
a 2-pin connector that can be used as a standby
switch. It should be attached to the appropriate pins
of the KABD-
250/230’s J12 header (STBY and GND)
as shown on the right.
Note:
You will notice this port has 3 pins but we only
use 2 pins, with the extra pin being “mute”. This port
could be used to sync the standby/mute of the KABD
amp with another Dayton Audio amplifier, but we do
not need the mute sync when the board is used
standalone. Instead we use the port to control
standby mode with a switch.
8.
Potentiometers
(Optional)
Attaching the potentiometers found in the functional
cable kit (sold separately) to the board in the 3-pin
POT1-4 ports can allow quick on-the-fly adjustments,
even without any programming. See the
potentiometers section for more details. POT1 can
immediately be used out of the box as an external
volume control.
Numerous SigmaStudio example projects are available
to reprogram the potentiometers for custom uses,
such as EQ tone controls, high/low pass filters, custom
volume controls, etc and can be easily customized.
