Description:
This PCB board adopts double-sided tinning, brand new Italian AV MKT, etc. capacitors (50V withstand voltage), and the resistance adopts 1/2W VISHAY and DALE resistors imported from the United States.
Tip: This board needs to be used with a rectifier and filter power board, which needs to be supplied with AC 22V to 28V. One board is one channel!
LM3886 is a monophonic, high-performance audio power amplifier IC produced by National Semiconductor (NS), with a maximum continuous output power of up to 60W.
The power amplifier adopts a mono design. The power amplifier part has a board for each channel, and the resistance on the board is an imported resistance. Other capacitors use WIMA, etc., and LM3886TF is the original authentic product of the country. The circuit board adopts double-sided blackboard with reasonable wiring and beautiful appearance.
Specification:
Working voltage: DC positive and negative double 20-28V
Output power: 68W (max.)
Power amplifier board dimensions: length 62mm/width 38mm
Weight: 35g
Power supply voltage: DC DC double 24V-42V, recommended double 30V DC (+/-30V DC), (recommended double 26V/100W toroidal transformer, DC voltage is about DC double 30V~35V after rectification and filtering)
Note: The sound quality of LM3886 at high voltage is much better than that at low voltage, but too high voltage will also bring the risk of easily damaging the amplifier)
Output load and power: 4Ω-8Ω, about 68W (+/-30V) 4Ω: about 38W (+/-30V) ; 8Ω: about 50W (+/-35V)
Package included:
1 x Amplifier Board
