      Product Details

      Dayton Audio KABD-430 4 x 30W All-in-one Amplifier Board with DSP and Bluetooth 5.0 aptX HD

       

      Leverage the convivence of Bluetooth 5.0 and powerful DSP to truly create customizable audio projects with the accessibility of wireless streaming. The Dayton Audio KABD-430 combines a 4 x 30W amp board, Bluetooth 5.0, and an ADAU1701 digital signal processor all in one amp board. The four-channel board provides the opportunity to expand your project in ways impossible before. The design of the KAB-430 enables you to customize your next DIY audio project's sound using SigmaStudio software and Dayton Audio KPX or ICP1 Bluetooth programmer.

       

      All-in-one KABD-430 Amp Board with DSP & Bluetooth
      The KABD-430 replaces the Dayton Audio DSPB-230 with a large array of new features and functionality. The KABD-430 provides high-quality Bluetooth steaming, external potentiometers, easily programmable DSP, and is optimized for longer battery life.

       

      What's New?

      • Bluetooth 5.0 with aptX HD for high quality and long-range streaming
      • Optimized for low power consumption for battery-powered projects
      • External potentiometer ports allow easy integration of volume, tone control, filters, and more for any project

       

      Other Included Features

      • Reliable and power-efficient Class D amplification
      • Easy to use plug-and-play solderless configuration
      • Integrated ADAU1701 DSP chip for ultimate signal control and customization via the free SigmaStudio software
      • DSP controlled line-level output for connecting powered subwoofers or external amplifiers
      • Bluetooth 5.0 or line-level AUX input accommodates wireless and wired audio connections.

       

      High-Quality Audio Performance
      The Dayton Audio KABD-430 DSP Amplifier Board delivers high-quality sound without drawing a lot of 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-430 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-430 amp board.

       

      Highest Quality Bluetooth
      The Dayton Audio KABD-430 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 onboard, antenna ensure stable wireless connectivity up to 15m (50ft.) The onboard 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 hobbyist or industrial purposes then nothing is required to enjoy the full convenience of pairing and streaming high-quality Bluetooth audio. The KABD-430 is also CE and FCC-ready for certification purposes.

       

      Included with the KABD-430 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 onboard 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.

       

      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. 

      SigmaStudio Programming

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

      • A Windows PC / Laptop with an 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. A 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 the 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 preventing 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
