Hi Quality/Power Audio Performance

The Dayton Audio KAB-2150 Bluetooth Amplifier Board delivers high quality, powerful sound using the Class D TPA-3255 amplifier chip. The TPA-3255 power efficiency enables it to deliver high wattage output using a special designed heatsink eliminating the need for a fan. Its high-power performance without a noisy fan makes this hi-fi amplifier board an integral asset in any quality audio build.

.

Integrated Bluetooth

Unlike other amplifier boards, the Dayton Audio KAB-2150 includes a built-in Bluetooth 5.0 module. This cost-effective version of Bluetooth enables easy pairing with any mobile device or tablet for convenient wireless access to audio. 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 Bluetooth audio. The KAB-2150 is also CE and FCC ready for certification purposes.

Single Line Output and Dual Line Input

There're several new features added to the KAB-2150 not found on other KAB boards. Check out the detailed on line manual to see the changes. One unique feature is a second line input. The KAB-2150 has a switch to choose between line input with Bluetooth, or line input with no Bluetooth. No Bluetooth option enables the KAB-2150 to act as a standalone stereo amplifier, or secondary amp with another amp board that might already have Bluetooth. This feature cuts out the tone controls and the line output along with the Bluetooth.

Easy Installation

Included with the KAB-2150 are multiple plug-n-play wiring harnesses that enable you to customize your project right out of the box. Three wire harnesses have Molex Mini Fit type connectors. One hooks to DC power and the other two connect to speakers. For many users, these cables are all that is needed to complete a project. The KAB-2150 also includes JST PH 2.0 type sockets to further customize your project. To make expansion easier the KAB-2150 comes with JST PH 2.0 type wiring harnesses and components so you don't have to go searching for the right function kit. Quickly plug in all the included accessories without any soldering or use only the accessories needed to complete a specific project. Find out more about optional accessories below.

Customized Bluetooth Amplifier

The KAB‐2150 could be built into a custom enclosure, such as the case of some old electronics, a custom 3D printed enclosure, or anything you can think of. The included wiring harnesses make it easy to mount all controls and inputs to whatever enclosure you choose. Other audio DIY ideas might include Bluetooth powered portable or desktop speakers.
