Dayton Audio DSPB-250 combines a 2 x 50W amp board with the ADAU1701 digital signal processor which enables you to customize sound using SigmaStudio software and Dayton Audio ICP1 Bluetooth programmer. Use the DSPB-250 as the heart of your DSP audio project, or combine it with the KAB-250v3 to make a Bluetooth DSP 4-channel project.
Dayton Audio DSPB-250 2x50W Class D Audio Amplifier Board with DSP
High Quality Audio Performance. The Dayton Audio DSPB-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.
Integrated DSP Chip: Unlike other amplifier boards, the Dayton Audio DSPB-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 DSPB-250 amp board.
Easy Installation: Included with the DSPB-250 are three wire harnesses: one for DC power, one for Line-input, 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.
