Small Projects Can Sound Awesome

The Dayton Audio KABM-215 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. DSP programing option and 2 x 15 watts of output, is more than enough power and sound customization to make small stereo speakers sound great, yet the board is small enough to integrate into nearly any project.

High Quality Audio Performance

The Dayton Audio KABM-215 Bluetooth Amplifier Board delivers high quality sound without drawing a lot power. This is due to the highly efficient Class D amplifier chip. The chip 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 KABM-215 includes a built-in Bluetooth 5.0 module with DSP programing option with KPX board (sold separately). The advantage of Bluetooth 5.0 is its low power consumption which prolongs the playtime of battery powered builds. High receive sensitivity with RF power up to 9 dBm and -90 dBm, and on board antenna insure stable wireless connectivity up to 15m (50ft.) On board external antenna jack enables the KABM board to be mounted in a metal enclosure with the included external antenna or a short rubber antenna kit (sold separately). 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 KABM-215 is also CE and FCC ready for certification purposes.

Since the KABM series includes all the wiring harnesses for additional functions it speeds-up the installation process and creates confidence for beginning builders because there's no need to solder or troubleshoot loose and unstable connections on the board. Dayton Audio also offers a variety of accessories with robust features to make installation even easier. Find out more about optional accessories below.

OPTIONAL ACCESSORIES

KABM Integration on KABM Amplifier Boards

While your KABM amplifier sounds great out of the box, the KABM DSP Control software is compatible with KABM amplifier boards (KABM-215, KABM-30M) when combined with a KPX programmer and the free KABM software offers extensive DSP customization with no experience required. The software provides simple control of 10 band of PEQ, High Pass Filters, Low Pass Filters, Compressor / Limiters, Bass Effects and more. KPX Programmer connection is only needed temporarily, DSP presets can be saved to the KABM amplifier itself and the programmer can be removed. This also means that one programmer can program as many amplifiers as needed. The KPX programmer firmware must must be upgraded to work with the KABM boards and KABM software. Refer to the KPX (325-139) user guide for instructions.

Optional Li-Ion Battery Charging Board

The Dayton Audio LBB-3v2 Li-Ion battery charging board holds three 18650 batteries (sold separately). This charging board has built in under/over voltage protection circuits for safe charging and longevity. It balances different voltage between batteries in case one battery discharges faster than the others. A 19 VDC, 1-5A power adapter works best for charging batteries contained in this board.

Please note: When removing batteries from the LBB-3v2, the charging adapter must be plugged in momentarily after the new batteries have been inserted. Failing to do so will prevent the amp board from powering up.

Optional Standoff Kit

The PC Board M3 Standoff Kit is perfect for stacking multiple PC boards that are the same size, like the a KAB amp board on top of the KAB-BE battery board. Stacking PC boards enables you to use a smaller project box to install your project in. These standoffs will secure a single PC board, or a stack, if you use it with KAB-AB mounting bracket. They both use the same M3 thread. The kit features eight 16mm studs, eight 10mm studs, and 4 Phillips screws.

High Performance Power Supply

To meet the wattage output as listed in the specifications, using a 15V 4A 120-057 is recommended. The power supply accepts inputs 100-240 VAC. Approved/listed by all major safety agencies; UL, CUL, and CE. Features a 4 ft. detachable AC input cord with a 4 ft. 2.1mm x 5.5mm x 9mm, center positive connector DC cable. This power supply can also be used with the LBB-3v2.
