Description
This audio amplifier board is a 4CH audio amplifier board specially designed for game machine applications, delivering 15W output power per channel. It features compact size, full protection and high reliability, applying to audio 4.0 system. Industrial pluggable terminal blocks make it easy to be integrated in systems. If you want this board to function as 2.1 (2 x 15W + 1 x 30W) or 2.0 (2 x 30W), please contact us for customization.
The volume is set at the maximum as default. External volume control potentiometer is also available for customers to achieve volume adjustment.
High Reliability and Stability Verified by Strict Tests
We have carried out extremely strict test for this board to ensure its reliability and stability. In addition to functional test and performance test, all boards go through HALT and HASS test before storage. All the test data have been recorded to form test report. If you have special requirements on test, please contact us.
