About KNACRO TPA3116D2 50W+50W Digital Power Amplifier
Dimension: 85.5×55×26 mm (Not included the projection of potentiometer (15mm)) Operating voltage range: DC 9-25V (Current above 3A, if you would like a higher power, 19-24V/above 4A is more suitable) Audio input sensitivity: Dual-channel 700mv; Parallel mono 850mv Speaker impedance: Dual-channel speaker: 3.5-8 Ω; Parallel bridge mono speaker: 2-4Ω Maximum output power: 50W (left channel) + 50W (right channel); Parallel bridge mono 100W Reverse connection protection: Yes. (Positive and negative reversal is not energized.) Audio input connector: Standard 3.5MM audio line input jack, or from 3P socket input audio. Reserve mute interface (MUTE), when needed, can connect to the pre-mute interface devices. Method of Wiring: 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! Package Includes: 1 × TPA3116 Amplifier Board If you have any question , please feel free to contact us.
