High Quality Audio Performance

The Dayton Audio DSPB-100 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. This board is preset to work as a subwoofer amp board. If you want to use it as a for full range amp board you must preprogram it with SigmaStudio.

Integrated DSP Chip

Unlike other amplifier boards, the Dayton Audio DSPB-100 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-100 amp board.

Easy Installation

Included with the DSPB-100 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. Dayton Audio also offers a variety of accessories with robust features to make installation even easier. Find out more about optional accessories below.

Optional Expansion Cables

Use the DSPB-EC cable kit to customize any Dayton Audio DSPB project. Each wire harness comes equipped with mini connectors for easy termination to the board, and each cable is 20" in length.

• The 6-wire cable combines sound level functions with the KAB-250v3 and KAB-230v3

• The 3-wire cable combines power functions with the KAB-250v3 and KAB-230v3.

• The 4-wire battery cable is for portable projects where AC or 12 VDC car power are not available. This cable plugs directly into all the Dayton Audio Li-Ion battery boards. If using the KAB-BE battery board you must also add the KAB-250v3 or KAB-230v3 to the project for charging purposes.

• Three LEDs green, blue, and red are in the kit for charge, Bluetooth, and power status if you add one of the KAB Bluetooth amp boards to the DSPB board. Each LED has its own 2-wire harness.

• Add an optional SPST unmarked switch (sold separately) to the 2-wire on/off power cable to cut power to the entire board.

Optional Programing Interface Board

The Dayton Audio DSPB-ICP1 provides a solution to programing the DSPB-100 amp board using SigmaStudio software. Download SigmaStudia software to your computer and send programming instructions using a micro USB cable (not included) to the DSP-ICP1 programing board that installs settings into the DSPB-100 amp board with the included 6-pin cable.

Please note: The included cable has the same 6-pin plug that joins the KAB-250v3 to the DSPB-100. Make sure the programing board plugs into J-4 or #8 in the quick reference guide.

Optional Li-Ion Battery Charging Board

The Dayton Audio KAB-BE Li-Ion battery charging board holds three 18650 batteries (sold separately). This charging board has built in under/over voltage protection circuits for safe charging and longevity. It balances different voltage between batteries in case one battery discharges faster than the others. A 19 VDC, 1-5A power adapter works best for charging batteries contained in this board. Additional boards can be sequenced together to provide longer playing time.

Please note: When removing batteries from the KAB-BE, the charging adapter must be plugged in momentarily after the new batteries have been inserted. Failing to do so will prevent the amp board from powering up.

Optional L-type Aluminum Bracket

It can be quite difficult to install the audio amplifier board into tight spaces such as portable sound applications. To securely mount the DSPB amplifer board and improve space efficiency Dayton Audio offers the KAB-AB; an optional L-type aluminum bracket. This aluminum bracket supports vertical and horizontal mounting configurations to satisfy different installation requirements. With four M3.5 screw lock standoffs, most Dayton Audio KAB and DSPB amplifier boards install easily on the bracket using the four included security screws. Two M3.5 holes and seven slots give you the versatility to mount the L-type bracket to your project as needed.
