      Tip:  Take a look at the table in this blogpost to see which power supply to choose for this product.

      High Quality Audio Performance

      The Dayton Audio KAB-215v2 Bluetooth Amplifier Board delivers high quality sound without drawing a lot power. This is due to the highly efficient AD82110 Class D amplifier chip. The AD82110 operates at 90% efficiency, thus eliminating the need for a heat sink and reducing its overall size. 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-215v2 includes a built-in Bluetooth 5.0 module. This cost effective version of Bluetooth enables easy pairing with any mobile device or tablet for convenient access to audio. 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 Bluetooth audio. The KAB-215v2 is also CE and FCC ready for certification purposes.

      Easy Installation

      Included with the KAB-215v2 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-215v2 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-215v2 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 - 21.5 VDC, and 20 - 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.

      Uitstekende versterker: prima geluid en voldoende vermogen, makkelijk in te bouwen dankzij de beugel. Met een minimale ingreep kon ik zelfs een schakelaar voorzien om over te schakelen tussen AUX en BT: verwijder de jumper in de AUX connector en maak een verbinding tussen DET en GND via een enkelvoudige schakelaar. DET aan GND activeert Bluetooth en schakelt AUX af, en omgekeerd.

      Ganz guter Verstärker, bloß gestaltet sich das laden des zusätzlichen Batteriehalters nicht ganz so einfach wie beschrieben. (man muss sich selber ein Akku-Pack bauen)
