Dayton Audio KABD-250 2 x 50W + DSP Amplifier Board aptX HD Bluetooth 5.0

Leverage the convivence 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. This enables you to customize your next DIY audio project's sound using SigmaStudio software and Dayton Audio KPX or legacy ICP1 Bluetooth programmer.

The new Dayton Audio KABD series of boards all provide integrated Bluetooth 5.0 with aptX, DSP, and plug-n-play hookup sockets. The line comes with a 2x30W, 2x50W, 4x30W, and 4x100W versions. Check out what you can build with the all new KABD line.

The KABD-250 replaces the Dayton Audio DSPB-250 with a large array of new features and functionality. The KABD-250 provides high quality Bluetooth steaming, external potentiometers, easily programmable DSP, and is optimized for a longer battery life.

What's new?

• Bluetooth 5.0 with aptX HD for high quality and long range streaming
• Optimized for low power consumption for battery-powered projects
• External potentiometer ports allow easy integration of volume, tone control, filters, and more for any project

Other Included Features

• Reliable and power efficient Class D amplification
• Easy to use plug-and-play solderless configuration
• Integrated ADAU1701 DSP chip for ultimate signal control and customization via the free SigmaStudio software
• DSP controlled line level output for connecting powered subwoofers or external amplifiers
• Bluetooth 5.0 or line-level AUX input accommodates wireless and wired audio connection

Dynamic Bass Enhancement increases the proportion of bass at lower volumes, while decreasing the proportion of bass at higher volumes. Common practice in commercial Bluetooth speakers, this allows for a full, bass heavy sound from small drivers or exciters at lower volumes, but protects them from being overdriven at higher volumes.

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.
