Summary Dayton Audio KABD-250 2 x 50W + DSP Amplifier Board aptX HD Bluetooth 5.0
High Quality Audio Performance The Dayton Audio KABD-250 DSP 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 88% efficiency, thus eliminating the need for a large 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.

Unlike other amplifier boards, the Dayton Audio KABD-250 includes a built-in ADAU1701 DSP chip. Create nearly limitless possibilities of EQ, crossover, bass enhancement, time alignment and more thanks to the ADAU1701 DSP chip. Make advanced crossovers with ease without circuit knowledge, capacitors, inductors, or preamp boards, and get almost immediate feedback on how your project sounds. SigmaStudio software and Dayton Audio DSPB-ICP1 programming board (sold separately) combine together to let you set audio parameters to produce hi-fi quality sound. Download SigmaStudio into your desktop or laptop computer and plug the small ICP1 board into the USB port using a micro USB cable (sold separately). To quickly adjust the sound there are four potentiometers on the KABD-250 amp board.

Detail zoom of Bluetooth chip Integrated Bluetooth
The Dayton Audio KABD-250 includes a built-in Qualcomm Bluetooth 5.0 module with aptX HD. The aptX HD streaming audio quality rivals that of CDs since the Bluetooth chip supports aptX, aptX HD, aptX LL, SBC & AAC. The advantage of Bluetooth 5.0 is its long 15m (50 ft.) wireless range and its low power consumption which prolongs the playtime of battery-powered builds. On board external antenna jack enables the KAB board to be mounted in a metal enclosure with an external antenna (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 KABD-250 is also CE and FCC ready for certification purposes.

Included with the KABD-250 are three wire harnesses: one for DC power, Bluetooth reset button, 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 additional on board connectors, wiring harnesses (sold separately) are available to speed-up installation and create confident connections without soldering. 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 Use this full function, adjustable amplifier board with built-in DSP chip and Bluetooth5.0 in endless wireless audio applications that seem impossible to produce the right sound quality. So if you’re a hobbyist or manufacturer enjoy presetting this full functioning 2 x 50W DSP amplifier board to peak performance in your finished product. The KABD-250 is also CE and FCC ready for certification purposes.
Portable Power Paths For portable applications, there are three battery holder/charging boards which permit the connection of li-Ion rechargeable batteries to power the board. First is the Dayton Audio LBB-3v2 3-cell 18650 battery holder/charger board that is the same size as the KABD-250 which makes it easy to stack the boards with standoffs. This battery board must use a 5 to 24 VDC power supply.

If you desire more wattage output, use the 5-cell 21 VDC Dayton Audio LBB-5Sv2 or LBB-5v2 board. They work with 5 to 24 VDC power supplies. The LBB-5S uses 18650 Li-Ion batteries, and the LBB-5 uses 26650 Li-Ion batteries which delivers more play time. These portable power sources are highly recommended since all three provide under/over voltage protection.

Please note: To achieve power output briefly plug in the recommended power supply into the battery boards after the batteries are installed or when the batteries are removed and reinstalled.
