Quick Start and Wiring Guide
Before You Start
The KAB-2150 is a plug and play amplifier designed for quick integration, with no experience or soldering
required. The following will highlight important details about how the amplifier works and how you can
make it work for your project. Please read carefully. If you are having troubles not answered in this
section, see the troubleshooting guide at the end of this document.
Power Supplies
•
The KAB-2150 is a highly powerful amplifier board, but it requires a powerful DC power supply in
order to achieve its maximum output potential. For maximum power, use a 36V 9A supply. If
you use a lower voltage supply, you cannot not reach the maximum power output.
•
The KAB-2150 is compatible with power supplies 18-36V (use 36V for maximum power).
•
Included with the KAB-2150 is a 2.5mm DC barrel jack wiring harness for easy power connection
with off the shelf power supplies (center positive, 2.5mm).
•
To prevent a potential spark, plug your power supply into the amplifier BEFORE plugging the power
supply into the wall.
Input Modes Description
The KAB-2150 supports 2 different input modes, Bluetooth Mode and Bluetooth Bypass Mode, which
can be toggled with the on-board switch. If you want to use Bluetooth as an input or use tone controls,
you must use Bluetooth Mode and plug any line input sources into the Bluetooth Line in port (J103). If
you wish to bypass the Bluetooth module for slightly better audio performance and latency using Line
In, you must use Bluetooth Bypass Mode and use its corresponding Line Input (J102). Bluetooth bypass
mode will pass the analog input directly to the amplifier chip, without going through the Bluetooth
module.

Bluetooth and Tone Control Mode
–
In this mode, the amplifier can receive audio either
via a wireless Bluetooth signal, or through an AUX jack connected to J103. All audio in
