AA-AB32231 is a stereo audio amplifier board which delivers 8W output power per channel into an 8Ohm load based on a Tripath-style Texas Instruments TPA 3110 chip, featuring high efficiency up to 90% and high audio performance with low THD+N. This board supports PBTL, which means it can be configured as mono 16W audio amplifier, which is simply achieved by switch without any need of soldering. In addition, AA-AB32231 supports not only single-ended input but also differential input. Low output power, compact size and high reliability making it suitable for DIY audio, home audio, industrial audio applications, kiosk, self-service equipment like vending machine, ticket machine, guide machine and so on. A DC8V – 19V power supply is required.

1 x 16W / 2 x 8W Mode ​ ​This audio amplifier board supports two operation modes, stereo 8W or mono 16W. You buy one board and get two modes, which is highly cost-effectively. Customers can switch between the two modes easily with only one step. As for the details on setting, please refer to the user manual.

Supporting Both Single-ended Input and Differential Input ​ ​2 RJ128 connectors and 1 3.5mm AUX IN jack are used for single-ended input connection. Differential input is also widely used in many applications as it features such strong ability to resist interference that it can effectively suppress common-mode interference. Fully considering that, Sure Electronics provides differential input with AA-AB32231. Please note that single-ended input and differential input cannot use at the same time and switches are offered for change. As for the details on setting, please refer to the user manual.

High Quality Audio Performance ​ ​By means of dedicated PCB layout design and engineers’ attentive debugging, this low power audio amplifier board features such high audio performance that you can get pure enjoy of the music, whose SNR reaches 100dB (differential input) and THD+N performs well as 0.02% @ 8Ohm, 1W, 1kHz.

Easy for Installation ​ ​Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Thanks to the pre-mounted industrial terminal interfaces, all you need to do is to plug in cables for connection, without any demand of soldering, which is swift and convenient. Power indicator is provided on board for customers to have an overview of the real-time condition of the amplifier board. This board is in 3’’ x 2’’ compact size, which can be easily integrated into any audio projects without occupation of too much space.

High Reliability and Long Service Time ​ ​Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Full protection circuit, like over temperature protection, overcurrent protection, over / under voltage protection, is equipped on this board for high reliability and long service time.

Suitable for Industrial Audio Applications ​ ​Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Full protection circuit, like over temperature protection, overcurrenThis board supports switch between stereo mode ad mono mode. It also supports both single-ended input and differential input. All the interfaces are mounted for easy connection and system integration. Thus, this board is applicable for industrial audio applications, especially for kiosk, vending machine, guide machine and small-scale game machine.
