    Note 4: about 3-Way Amplified System with DSPB and KAB amplifiers If you want to create a 3-way pair of speakers with all active crossovers and built in amplification, it is possible with the combination of DSPB and KAB amplifiers and programming within SigmaStudio. To create a powered, 3-way mono speaker, an example shopping list would be the following.

  • Page 5: Quick Start Guides

    2. Quick Start Guides The Dayton Audio DSPB series of boards leverages the powerful Analog Devices ADAU1701 DSP chip to allow for almost limitless possibilities for sound customization. Out of the box, a DSPB-100/250 or a DSPB-K will allow for quick adjustments with the convenient built in potentiometers, but to unlock the full potential of the ADAU1701 processor, combine your board with a Dayton Audio DSPB-ICP1 to connect directly to the SigmaStudio development tool provided by Analog Devices.
