This is due to the highly efficient TDA749x Class D amplifier chips. The TDA749x operates at 89.5% 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 ChipUnlike other amplifier boards, the Dayton Audio KABD-4100 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-4100 amp board..Highest Quality BluetoothThe Dayton Audio KABD-4100 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-4100 is also CE and FCC ready for certification purposes.Included with the KABD-4100 are four wire harnesses: One for DC power, a Bluetooth reset button, and two sets of speaker wires. For many users, these cables are all that is needed to complete a project. Since the board has four channels you need the two sets of speaker wires to create a 2.1 or four channel audio project. With the 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.
