Description:


1. 15W+15W Audio Amplifier Board


(1) Parameters:


--- Working voltage: DC8-26V, can be operated by DC 12V 24V

--- Output power: 15W stereo (24V 8ohm)/ 10W stereo (12V 8 ohm), if connect 4-ohm or 2-ohm speaker, the power will be automatically limited to 15W

--- Input methods: single-ended (default), difference (to choose by the jumper)

--- Efficiency: >90%

--- THD (total harmonic distortion)&noise: <0.2%

--- Low quiescent current

--- Noise suppression

--- Size: 75.69*41.96mm

--- Materials: high-grade pure black immersion gold circuit board, import WIMA red sound capacitor, each channel large capacity filter capacitor. Special customized pure black copper terminals, gold-plated audio input terminals.

--- Protective functions: input reverse protection, short-circuit protection, over-current protection, over-heat protection, over-voltage protection, low-voltage protection, EMI.


(2) Other functions:


External mute function (MUTE: High level mute, factory default low level)

External turn-off function (SD: Low-level chip turn-off, factory default high level)

To use the mute/sd function, just remove the resistance next to the MUTE welding spot and add a switch between the welding spot under the resistance and the welding spot next to MUTE/SD.
