The Next Level of DSP Amplification

Leverage the convenience of Bluetooth 5.0 and powerful DSP to truly create customizable audio projects with the accessibility of wireless streaming. The Dayton Audio KABD-250 combines a 2 x 50W amp board, Bluetooth 5.0, and an ADAU1701 digital signal processor all in one amp board.

Integrated Bluetooth 5.0 with AptX HD

The KABD-250 includes a built-in Qualcomm Bluetooth 5.0 module with aptX HD. The advantage of Bluetooth 5.0 is its low power consumption which prolongs the playtime of battery-powered builds. The streaming audio quality rivals that of CDs since the Bluetooth chip supports aptX, aptX HD, aptX LL, SBC & AAC.

DSP Controlled Line Level Output

The Dayton Audio KABD-250 DSP Amplifier Board delivers high-quality sound without drawing a lot of 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.

Precise Tonal Control

With the KABD-250, you can achieve precise tonal control using the external potentiometers which will adjust the filter based on the position of the potentiometer. This filter works by pre-calculating a specific number of filters based on user parameters, and then storing them into the DSP memory.

Project Ideas

Use this full-function, adjustable amplifier board with built-in DSP chip and Bluetooth 5.0 in endless wireless audio applications that seem impossible to produce the right sound quality.
