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.
A. Before you start
1. Review the wiring diagrams found at the end of this document or on the product page for each
device before using this
quick start guide. Refer to these diagrams as you’re following the quick
start guides.
2. Review the “What do I need to purchase?” guide abov e to make sure you have everything
needed to achieve your design goals.
3. Make sure that any speakers and input devices you plan on connecting to the DSPB are working
properly.
4. If planning to use SigmaStudio to use the full potential of the DSP, make sure you have
purchased at least one DSPB-ICP1, a micro USB cable capable of data transfer (some cables
included with devices that use a micro USB port for power are power only, and do not connect
the pins necessary for data transfer!), and make sure you have a Windows PC available to use
the free SigmaStudio software.
5. Take care when attaching and especially removing jumper cables from the DSPB.
a. A damaged cable can cause issues that are difficult to troubleshoot, such as noises like
popping or clicking. A damaged cable can also cause programming issues.
6. To achieve increased power from a DSPB amplifier, try increasing the input volume before
increasing the gain of the amp to max levels. This will generally result in a better response from
the amp.
a. For example, increase the volume of an attached mp3 player before adjusting the
potentiometer on the board to increase output volume.
