Summary Dayton Audio KAB-100M 1x100W Class D Audio Amplifier Board with Bluetooth 4.0

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.

  • Bluetooth 4.0 with aptX built directly into board – no need for a separate module
  • U.FL IPX coaxial connector for internal or external Bluetooth antenna (internal antenna included) and a Bluetooth pairing reset switch
  • Separate ports for powering by battery or direct DC input from a power adapter
  • Optional Accessories expand functionality and more
  • 5 year Dayton Audio Warranty

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. For orders greater than 20 units, custom OEM Bluetooth pairing names are available — email [email protected] for more details. 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 KAB-100M 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.

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)
