1. 15W+15W Audio Amplifier Board
--- 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.
