Note: The 3P input jack "Lin" -- is the source left channel input, and the "G" -- is the source common ground "Rin" -- is the source right channel input.Parameters:Audio input sensitivity: 600-800mVFrequency response range: 20Hz-20KHzSpeaker impedance: left and right channels: 4-8 ohms, bass channel: 2-8 ohmsDimensions: 101 (W) x 100 (D) x (H) <;30mm, excluding potentiometers and socket extensionsOperating voltage range: DC11-24V (current 3-4A, or 19-24V/4-5A, if the power requirement is higher than 20-24V/8-9A) such as using AC transformer power supply, it must be rectified and filtered a direct current DC power supply is available for use. Note that the DC no-load voltage should not be greater than 25.5V (this is very important)Supports up to 50W (left channel) + 50W (right channel) + 100W (bass channel) for three channels.Wide working voltage, energy-saving design, efficiency up to 90%.You can use a good performance switching power supply, laptop switching power supply, you can also use a charging bottle, or car power supply, etc...Package included:1 x TPA3116 digital audio amplifier board
