Dayton Audio KAB-230v4 2 x 30W Class D Audio Amplifier Board with aptX HD Bluetooth 5.0

Easy to use Bluetooth 5.0 and amplification

The Dayton Audio KAB-230v4 Bluetooth Amplifier Board makes it quick and easy to add audio to your project, speaker build, point-of-purchase display, kiosk, or any location where music or sound enhances the experience. With an output of 2 x 30 watts, there is more than enough power to drive stereo speakers, yet the board is small enough to integrate into nearly any project.

 
High Quality Audio Performance
 

The Dayton Audio KAB-230v4 Bluetooth 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 90% efficiency, thus eliminating the need for a 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 Bluetooth
 

Unlike other amplifier boards, the Dayton Audio KAB-230v4 includes a built-in Qualcomm Bluetooth 5.0 module with aptX HD and DSP programing option with KPX board (sold separately). 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 KAB-230v4 is also CE and FCC ready for certification purposes.

Easy Installation

Due to the overall audio performance and built-in Bluetooth with DSP Programing option, this amp board has almost endless application possibilities.Included with the KAB-230v4 are two wire harnesses: one for DC power 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 with wiring harnesses (sold separately) available to speed-up installation and create confident connections, there is no need to solder or troubleshoot loose and unstable contacts. Dayton Audio also offers a variety of accessories with robust features to make installation even easier. Find out more about optional accessories below.

 
Endless Applications

Due to the overall audio performance and built-in Bluetooth with DSP Programing option, this amp board has almost endless application possibilities. From hobbyists and DIYers to manufacturers and installation organizations this Bluetooth amp board has immense flexibility. For orders greater than 20 units, custom OEM Bluetooth pairing names are available – email info@daytonaudio.com for more details. Even if you bypass the Bluetooth feature, this amplifier board integrates easily into any job because of its array of included and optional wiring harnesses. Examples of applications include:

 
 
Extreme Low Standby Power

The Dayton Audio KAB-230v4 will remain powered up to 7 days in standby mode even while Bluetooth is enabled. This standby time is approximately 4x longer than the competition due to the use of a high efficiency DC/DC converter which minimizes power consumption thanks to the employment of a micro controller as the PMU (Power Management Unit).

The Dayton Audio KAB-230v4 features numerous power options for creative, wireless sound projects. This flexibility eliminates limitations often caused by most other amp boards. Therefore, your design can be cord restricted or truly portable.

For portable applications, there is an optional function cable kit (KAB-FC) which permits the connection of rechargeable batteries to power the board. NiMH, lead acid, or NiCad batteries will recharge straight from the board using a 15~24 VDC, 1A power supply. Use extreme caution because the Bluetooth amp board does not provide under/over charge protection and the connected power adapter cannot have an output greater than 30 watts.

Solar charging is also an option; this application requires solar batteries with float (open) voltage with 16.5 to 21.5 VDC, and 20 to 100 watt panel. Eight AA alkaline batteries can also power this board, but do not connect the recharging feature for this type of use.

Multiple Power Paths

The best rechargeable battery option makes use of a separate interconnect board from Dayton Audio (KAB-BE) which holds three 18650 Li-Ion batteries. This portable power source is highly recommended since this add-on battery holder board does provide under/over voltage protection. A 19 VDC, 1-5A power supply is your best choice for charging the expansion board. (15 VDC Min required and 24 VDC Max).

KABX Integration on KAB Amplifier Boards

While your KAB amplifier sounds great out of the box, the KABX DSP Control software is compatible with new generation KAB amplifier boards (KAB-250v4, KAB-230v4, KAB-100Mv2) when combined with a KPX programmer and the free KPBX offers extensive DSP customization with no experience required. The software provides simple control of 10 band of PEQ, High Pass Filters, Low Pass Filters, Compressor / Limiters, Bass Effects and more. KPX Programmer connection is only needed temporarily, DSP presets can be saved to the KAB amplifier itself and the programmer can be removed. This also means that one programmer can program as many amplifiers as needed.
