High Quality Audio Performance

The Dayton Audio KABD-230 DSP Amplifier Board delivers high quality sound without drawing a lot power. This is due to the highly efficient TPA3118 Class D amplifier chip. The TPA3118 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 KABD-230 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 capacitors, inductors, or preamp boards, and get almost immediate feedback on how your project sounds. SigmaStudio software and Dayton Audio DSPB-ICP1 or KPX programming boards (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 or KPX board into the USB port using a USB cable (sold separately). To quickly adjust the sound there are four potentiometers (sold separately) that plug into four sockets on the KABD-230 amp board..

 
 

 

Highest Quality Bluetooth

The Dayton Audio KABD-230 includes a built-in Qualcomm Bluetooth 5.0 module with aptX HD. The advantage of Bluetooth 5.0 is its low power consumption which prolongs the playtime of battery powered builds. The streaming audio quality rivals that of CDs since the Bluetooth chip supports aptX, aptX HD, aptX LL, SBC & AAC. High receive sensitivity with RF power up to 9 dBm and -90 dBm, and on board antenna insure stable wireless connectivity up to 15m (50ft.) On board external antenna jack enables the KAB board to be mounted in a metal enclosure with an external antenna (sold separately). Designed and built for Bluetooth demonstration purposes, this fully functioning module provides a turn-key approach to Bluetooth certification for consumer goods. If the application of this board is for the hobbyist or industrial purposes then nothing is required to enjoy the full convenience of pairing and streaming high quality Bluetooth audio. The KABD-230 is also CE and FCC ready for certification purposes.

Included with the KABD-230 are three wire harnesses: one for DC power, a Bluetooth reset button, 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.

Adding optional potentiometer controls has never been easier

 

  • Completely customizable with SigmaStudio, external potentiometers can be programmed for on the fly adjustment of volume control, tone controls, high and low pass filters and so much more
  • Set limits on max volume to prevent accidental overloads to your speakers
  • Can’t decide on one fixed treble level for your portable speaker? Put a treble knob on it and adjust it on the spot
  • Love the bass during the day, but want to tone it down at night? Add a bass knob!
  • Set high/low pass variable frequency filters to fine tune your sound
  • Potentiometers headers can also be configured for toggle switches or push buttons for toggling presets or custom sound modes

 

 

SigmaStudio Integration

Although your KABD amplifier houses its own ADAU1701 DSP chip, to communicate with your PC, a USBi programmer is required. Dayton Audio has two compatible programmers -- the DSPB-ICP1 and the KPX. The programmer can be thought of as the bridge between your PC and your DSP chip so that they can communicate.

What do I need to connect my KABD Amplifier to SigmaStudio?

 

  • A Windows PC / Laptop with available USB Port
  • The free SigmaStudio download
  • A KABD Amplifier and recommended power supply
  • A compatible USBi programmer and USB cable
    • Dayton Audio DSPB-ICP1 (Micro USB)
    • Dayton Audio KPX (USB Type C)

 

 

Bass Optimization

Low pass and infrasonic (high pass) filters offer total control over the range your woofers play, and precise PEQ can optimize the bass response of the woofer to your tastes. EQ could even be used to apply room equalization to improve the accuracy of your speaker’s bass performance inside of a specific room.

 

 
 

 

Dynamic Bass Enhancement

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.

SuperBass

SuperBass algorithm uses principles of psychoacoustics to increase perception of bass by generating harmonics above the chosen crossover frequency. This can be especially useful when using small drivers or exciters.

Bass Boost

Analog Device’s Dynamic Bass Boost Algorithm will provide more bass boost at lower input levels than it will at higher volumes. This type of boost is incredibly common in portable speakers, creating the effect of the speaker sounding full and bass-y at low volumes, but prevents overdriving the speaker at higher volumes. If this block is too confusing or in depth for you, see the next page for a simpler version.

 

Precise Tonal Control

This could include things such as selective bass boosts, treble boosts, or even just precise filters to correct other errors in frequency response.

Parametric EQ

There are many types of filter blocks, however the parametric EQ block allows for graphic, easy to use and precise adjustment of numerous bands of peaking filters, high/low pass filters, tone shelves and more.

Potentiometer Controlled Filters

Control your filters with the external potentiometers which will adjust the filter based on the position of the potentiometer. This filter works by pre-calculating a specific number of filters based on user parameters, and then storing them into the DSP memory

 

Project Ideas

Use this full function, adjustable amplifier board with built-in DSP chip and Bluetooth 5.0 in endless wireless audio applications that seem impossible to produce the right sound quality. So if you’re a hobbyist or manufacturer enjoy presetting this full functioning 2 x 30W DSP amplifier board to peak performance in your finished product. The KABD-230 is also CE and FCC ready for certification purposes. To add more channels to your project use the line output socket with another amp board using wiring kit KABD-SPF (sold separately). Examples of applications include:

Portable Power Paths

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-230 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.

Optional Programing Interface Board

The dual-purpose Dayton Audio KPX allows you to unlock the full potential of your DSPB/KABD amplifier or preamp boards by connecting them to the easy to use, Analog Devices SigmaStudio visual programming tool. KPX also enables you to use KABX software to preset equalization settings and more for the KAB-250v4, KAB-230v4, and KAB-100Mv2.  Download SigmaStudia software to your computer and send programming instructions using a micro USB cable (not included) to the KPX programing board that installs settings into the KABD-4100 amp board with the included 6-pin cable.

Please note: The included cable has the same 6-pin plug that joins the KAB-230v3 to the KABD-230. Make sure the programing board plugs into J-5 or #7 in the quick reference guide.

Optional Li-Ion Battery Charging Board

The Dayton Audio LBB-3v2 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. 12 to 24 VDC, 1-5A power adapters work best for charging batteries contained in this board, but they accept as low as 5 VDC adapters. Higher rated voltage and current charge the batteries faster.

For more power output and longer play time use the Dayton Audio LBB-5Sv2 and LBB-5v2 battery boards. The Dayton Audio LBB-5Sv2 18650 5-cell battery board delivers more voltage output which increase the wattage output of the KABD-230. The Dayton Audio LBB-5v2 26650 5-cell battery board delivers more voltage output and has more current available which increase the wattage output and play time for the KABD-230.

Please note: When removing batteries from the LBB series battery boards, 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 KABD-230 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.

Optional Standoff Kit

The PC Board M3 Standoff Kit is perfect for stacking multiple PC boards that are the same size, like a DSPB amp board on top of the LBB-3 battery board. Stacking PC boards enables you to use a smaller project box to install your project in. These standoffs will secure a single PC board, or a stack, if you use it with KAB-AB mounting bracket. They both use the same M3 thread. The kit features eight 16mm studs, eight 10mm studs, 4 pcs 10mm, and 8 Phillips screws.

High Performance Power Supply

To meet the wattage output as listed in the specifications, using a 24V 5A DC Switching Power Supply is recommended. The power supply accepts inputs 100-240 VAC. Approved/listed by all major safety agencies; UL, CUL, and CE. Features a 5 ft. detachable input cord with a 2.5mm x 5.5mm x 9mm, center positive connector. This power supply can also be used with the KAB-BE.
