Picture Showcase

Description

AA-AB32131 is a stereo low power audio amplifier board, which delivers 2W output power per channel into a 4Ohm load based on Class D topology and PAM’s PAM8803 chip, featuring high quality audio performance and compact size. High speech intelligibility and low output power make this board perfectly suitable for kiosk, self-service equipment like vending machine, guide machine, ticket machine, service robots and so on. A DC4.5V - 12V power supply is required.

Suitable for Kiosk

Self-service equipment and small-scale kiosk, game machines need low output power and high speech intelligibility. Taking the labor cost and maintenance cost into consideration, compact size, easy installation and high reliability are of the most importance. AA-AB32131 meets all the requirements and is applicable to kiosk applications.

Supporting Battery Power

AA-AB32131 also supports battery power, which greatly improves the system portability. It is suggested to use a DC3V – 5V battery. With its low power consumption, it supports long playback time even we use it outside.

On-board and External Volume Control

There are two tactile buttons on the board for volume control. You can adjustment volume conveniently. If you want external volume control, we also provide a connector for external rotary encoder board.

Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. Audio signal is input by a 2510 connector or a 3.5 mm headphone jack. 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.
