Extreme Low Standby Power

 

The Dayton Audio KAB-230v3 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).

 

Multiple Power Paths

 

The Dayton Audio KAB-230v3 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.

Eight AA alkaline batteries can also power this board, but do not connect the recharging feature for this type of use.

The best rechargeable battery option makes use 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)

• Recommended recharging power supply (Li-Ion) 19 VDC, 1-5A 
• Board mounting holes center to center spacing: 3.32" x 2.4" (84 x 61 mm)
• Hole diameter: 0.14" (3.5 mm)
• Dimensions: 3.6" L x 2.7" W x 0.9" H

Optional Function Cables

Use the KAB-FC cables to customize any Dayton Audio KAB project. This four-cable kit comes equipped with Molex Mini Fit Jr connectors for easy termination to the board, and each cable is 20" in length.

• The AUX-in cable with 3.5 mm jack feeds music from any analog source directly to the KAB-230v3 board, enabling audio play from almost any non-Bluetooth source.

• The volume control with cable lets you manually control sound levels, and mounts into a 0.3" hole.

• The battery cable is for portable projects where AC or 12 VDC car power are not available. Multiple types of rechargeable batteries work with this cable and the board will charge the batteries when using an adapter with 15 to 24 VDC. Output wattage of the power adapter should never exceed 30 watts, as there is no under/over charging protection built in to the KAB-230v3 board.

• Using the on/off power cable cuts power to the entire board, but still provides power to the connected batteries for charging. An optional SPST switch is needed to accomplish this function.

Optional LED Light Status Cables

The KAB-LED light cable kit includes three different status LEDs that are clear when not in use, but light up blue, red, and green. The blue LED is used as the Bluetooth indicator, the red LED indicates power, and the green LED indicates charging.

Optional Interface Extension Board

The Dayton Audio KAB-INT provides a simple plug and play solution for custom applications. This interface board provides a 3.5 mm AUX-in jack, two USB A female ports for charging external devices, a momentary pushbutton switch that controls the standby function, and LED indicators for power and charging status. With the included 10-pin cable, the interface extension board easily plugs directly into the KAB-230v3 board.

Optional Li-Ion Battery Charging Board

The Dayton Audio KAB-BE 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. A 19 VDC, 1-5A power adapter works best for charging batteries contained in this board. Additional boards can be sequenced together to provide longer playing time.

Please note: When removing batteries from the KAB-BE, 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 KAB-230v3 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, any Dayton Audio KAB board installs 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.
