Specification: Origin: Mainland China Model: XH-M139 Material: Electronic components Chip selection: TPA3116D2 * 2 Power supply voltage: DC12-24V Output power: 200W (50w * 2+100w bass * 1) Signal to noise ratio: 100db Output load: 4-8 ohm Frequency response range: 14-100KHZ Number of channels: 3 (left channel+right channel+bass) Switching frequency: 1.2MHZ Size: About 100x80x28mm/3.93x3.14x1.10inch Weight: 118g Kind reminder: Only when the audio input is sufficient and the power supply voltage/current is sufficient can there be sufficient output power. The higher the power supply voltage, the higher the relative power, and the horn with different impedances will have different output power. When the voltage and current are sufficient, the larger the ohm number of the horn, the lower the relative sound power. Please pay attention! Power supply voltage: 12V - 8 Euro speaker/12W (left channel)+12W (right channel) 4 Euro speaker/20 (left channel)+20W (left channel), 15V - 8 ohms/18+18W, 4 ohms/greater than 30+30W, 19V - 8 ohms/32+32W, 4 ohms/greater than 45+45W, 24V - 8 ohms/38+38W, 4 ohms/greater than 55+55W, Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
