Supply voltage: DC 12V-22V. Maximum output power: 2X50W + 100W. Efficiency:> = 90%.SNR: 100dB. Total harmonic distortion: (50W / 1KHz / 24V / 4Ω - 0.1%) (30W / 1KHz / 24V / 8Ω - 0.1%). Frequency range: 20Hz-20KHz. Input impedance: 30KΩ.Speaker: 4-8Ω. Voltage gain： 26dB. Supply voltage: DC 12V-22V. Maximum output power: 2X50W + 100W. Efficiency:> = 90%. SNR: 100dB. Total harmonic distortion: (50W / 1KHz / 24V / 4Ω - 0.1%) (30W / 1KHz / 24V / 8Ω - 0.1%). Frequency range: 20Hz-20KHz. Input impedance: 30KΩ. Speaker: 4-8Ω. Voltage gain 26dB. Amplifier board size: 75 * 48 * 16mm (L * W * H) (excluding the potential size of the handle protruding portions). Potentiometer center distance: 25mm. Weight: 57 g. Caution: 1.The power supply voltage limit of 24V, do not exceed! Otherwise easily capacitance explosive slurry, rectified AC voltage spikes do not exceed 25V. Do not exceed the power supply voltage, positive and negative do not reversed. 2.Recommended power supply is 22V, 200W power supply is better than filtering. 3.The speaker recommended Satellite Speaker 4 ohm, 2 ohm subwoofer speaker. 4.Do not short circuit the audio output is shorted to ground or to each other. 5.Please carefully check before electricity, ensure the wiring is correct after only pass..
