The Dayton Audio KAB-100M Bluetooth Amplifier Board makes it quick and easy
to add audio to your project, speaker build, point-of-purchase display, kiosk,
or any location where music or sound enhances the experience. With an output of
1 x 100 watts, there is plenty of power to drive a small subwoofer or midsized
speaker project, yet the board is small enough to integrate into nearly any
project.

High Quality Audio Performance
The Dayton Audio KAB-100M Bluetooth Amplifier Board delivers high quality
sound without drawing a lot power. This is due to the highly efficient TPA3116
Class D amplifier chip. The TPA3116 operates at 90% efficiency. The added heat
sink mitigates any issues that may arise from excess heat. Its high efficiency
becomes a major advantage when powering from batteries as it prolongs the
playtime of a single charge. Its ultra-low distortion and pop-free performance
make this hi-fi amplifier board an integral asset in any quality audio
build.
Integrated Bluetooth
Unlike other amplifier boards, the Dayton Audio KAB-100M includes a
built-in Bluetooth 4.0 module with aptX. The advantage of Bluetooth 4.0 is its
low power consumption which prolongs the playtime of battery powered builds. The
streaming audio quality rivals that of CDs thanks to the addition of the aptX
codec by CSR. Designed and built for Bluetooth demonstration purposes, this
fully functioning module provides a turn-key approach to Bluetooth certification
for consumer goods. If the application of this board is for the hobbyist or
industrial purposes then nothing is required to enjoy the full convenience of
pairing and streaming high quality Bluetooth audio. The KAB-100M is also CE and
FCC ready for certification purposes.
Easy Installation
Included with the KAB-100M are two wire harnesses: one for DC power and the
other for connecting to stereo speakers. For many users, these cables are all
that is needed to complete a project. Since they have Molex Mini Fit Jr
connectors to speed-up installation and create confident a connection, there is
no need to solder or troubleshoot loose and unstable contacts. Dayton Audio also
offers a variety of accessories with robust features to make installation even
easier. Find out more about optional accessories below.
Endless Applications
Due to the overall audio performance and built-in Bluetooth, this amp board
has almost endless application possibilities. From hobbyists and DIYers to
manufacturers and installation organizations this Bluetooth amp board has
immense flexibility. Even
if you bypass the Bluetooth feature, this amplifier board integrates easily into
any job because of its array of included and optional wiring harnesses.
Extreme Low Standby Power
The Dayton Audio KAB-100M will remain powered up to 7 days in standby mode
even while Bluetooth is enabled. This standby time is approximately 4x longer
than the competition due to the use of a high efficiency DC/DC converter which
minimizes power consumption thanks to the employment of a micro controller as
the PMU (Power Management Unit).
Multiple Power Paths
The Dayton Audio KAB100M features numerous power options for creative,
wireless sound projects. This flexibility eliminates limitations often caused by
most other amp boards. Therefore, your design can be cord restricted or truly
portable.
For portable applications, there is an optional function cable kit (KAB-FC)
which permits the connection of rechargeable batteries to power the board. NiMH,
lead acid, or NiCad batteries will recharge straight from the board using a
15~24 VDC, 1A power supply. Use extreme caution because the Bluetooth amp board
does not provide under/over charge protection and the connected power adapter
cannot have an output greater than 30 watts.
Solar charging is also an option; this application requires solar batteries
with float (open) voltage with 16.5 to 21.5 VDC, and 20 to 100 watt panel.
Eight AA alkaline batteries can also power this board, but do not connect
the recharging feature for this type of use.
The best rechargeable battery option makes use a separate interconnect
board from Dayton Audio (KAB-BE) which holds three 18650 Li-Ion batteries. This
portable power source is highly recommended since this add-on battery holder
board does provide under/over voltage protection. A 19 VDC, 1-5A power supply is
your best choice for charging the expansion board. (15 VDC Min required and 24
VDC Max)
