Power Supply not included

Dimension: 85.5×55×26 mm (Not included the projection of potentiometer (15mm))
19-24V/above 4A is more suitable)
Audio input sensitivity: Dual-channel 700mv; Parallel mono 850mv
Speaker impedance: Dual-channel speaker: 4-8
Maximum output power: 50W (left channel) + 50W (right channel)
Audio input connector: Standard 3.5MM audio line input jack, or from 3P socket input audio.
1. Check the indicate instruction carefully before wiring.
2. Connect the speaker wire: speaker + connects to Lout -, speaker - connects to Rout -.
3. Connect the audio input wire.
4. Plug in the power after confirming if the wiring is correct. To change the wiring or move the board, you must unplug the power firstly.
Use Notes:
1. Power supply cannot connect to the output interface of the speaker, or the chip will be damaged.
2. The board cannot be placed on the metal surface, electrically conductive objects or wet objects which will cause short circuit or induced current sound.
3. Output power: Tip: To the audio input in sufficient supply voltage / current enough, will have enough output power. Higher relative power supply voltage will be bigger, different speakers have different impedance output power. Under voltage and current enough, the number of speakers in Europe, the smaller the relative sound power, please pay attention!
