Quick Start and Wiring Guide
Before You Start
•
Make sure that any speakers and input devices you plan on connecting to the KABD are working
properly.
•
If using SigmaStudio to use the full potential of the DSP, make sure you have purchased at least
one programmer board (ICP1 or KPX), an appropriate USB cable capable of data transfer and
make sure you have a Windows PC available to use for Analog Devices’ free SigmaStudio
software.
•
Take care when attaching and especially removing jumper cables from the KABD.
o
A damaged cable can cause issues that are difficult to troubleshoot, such as noises like
popping or clicking. A damaged cable can also cause programming failure.
•
Note that there is a ‘tips and troubleshooting’ section at the bottom of this document.
•
This guide will frequently reference ports on the amplifier such as “J8” or “J6”. These markings
are written on the board itself in small print and are usually easy to find, but if unsure, reference
the quick start wiring diagram below.
•
This guide is for the KABD-250/230 amplifiers, which have a built in Analog Devices ADAU1701
signal processing chip. The normal KAB (without the D at the end) amplifiers do not have this
chip, and this user guide
does not apply
to these boards.
•
There are separate manuals for the KABD-4100 and KABD-430, which are 4 channel amplifiers.
This manual is for the 2 channel KABD amplifiers, which are the KABD-250 (2 x 50 Watt) and
KABD-230 (2 x 30 Watt)
Power Supplies
•
DC Power
- The KABD-250/230 can be powered via J8 a DC power supply from 12-24V with
current capabilities greater than 1A. Any power supply outside of this specification can
damage the KABD-250/230 . In general, the higher wattage the power supply, the more
power that can be supplied to your speaker. For maximum power, use a 24V, 5A DC power
supply.
•
Battery Power
- The KABD-250/230 can also be easily powered with an external Dayton
Audio battery board via J6. The KABD-250/230 does NOT have a battery charging circuit on
the board, so the attached battery board must have this built in
. Dayton Audio battery
boards such as the LBB-3v2 (12V) or LBB-5Sv2 (21V) will work with any KABD series
amplifier
. Battery modules such as the Dayton Audio KAB-BE are not compatible with the
KABD series because these battery modules do not have built in charging circuits (amplifiers
such as the KAB-250v4 have charging circuits on the board, but the KABD-250/230 does not
have this circuit on the board).
Input Devices
•
Bluetooth -
The KABD-250/230 has Bluetooth 5.0 built directly onto the board wired directly
to the ADAU1701 DSP chip via I2S. This supports apt-X, aptX-HD, apt-X LL, SBC and AAC.
•
Analog -
Analog audio sources can be input to the KABD-250/230 via J9. A 3.5mm aux-in
cable is available in the KABD-SPF function cables kit for the KABD series.
o
Do not use input voltages higher than 2V or audio performance will reduce.
