Brand NEW! The Dayton Audio KAB-100Mv2 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 1 x 100 watts, there is more than enough power to drive stereo speakers, yet the board is small enough to integrate into nearly any project. Key Features Efficient 1 x 100 watts of power from the TPA3116 amp chip Bluetooth 5.0 with aptX HD built directly into board -- no need for a separate module Add programmable sound customization with the free KABX software via the KPX programmer board (sold separately) Plug-N-Play JST-PH and Molex Mini-Fit Jr wire harnesses make installation quick and simple -- includes power, Bluetooth reset button and speaker cables Separate ports for powering by battery or direct DC input from a power adapter Optional accessories expand functionality and more 5-year Dayton Audio warranty Extreme Low Standby Power The Dayton Audio KAB-100Mv2 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-100Mv2 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). ________________________________ Package Includes One Dayton Audio KAB-100Mv2 Bluetooth Amplifier Board One 2-conductor power cable 20" One 4-conductor speaker cable 20" One Bluetooth pairing reset push button switch with cable 20" ________________________________ Specifications Power output (w/ 24 VDC power supply): 1 x 100W @ 2 ohms SNR: 92 dB THD: 0.02% @ 2 ohms, 10W, 1 kHz Frequency response: 22 to 22,000 Hz (3 dB) Impedance: 2-8 ohms Bluetooth range: 30 ft.
