DROK TPA3116 Digital Power Amplifier Board 12-24V High Power Amplifier Module 50+50W Power Amplifier Chip with Volume Adjustment Potentiometer Switch Support PBTL 100W

Feature

Adopt Tpa3116 high-performance amplifier chip as the core, DC single power supply, wide operating Voltage range(9-25v, maximum Voltage is No more than 25V)
Maximum output power: 50W (left channel) + 50W (Right channel), dual- channel output, efficiency up to 90 percent
Support pbtl 100W mono output and reserve mute interface (mute), when needed, can connect to the pre-mute interface devices
Power anti-shock protection design, No pop sonic Boom when turn on/off
Increase the heat sink to meet with high-voltage power supply, cooling at high power output state needs

Description

Product Parameters:
Dimension: 85.55526 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 ; Parallel bridge mono speaker: 2-4
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!
