Low-pass filter board Single power, 10-24V ultra-heavy subwoofer
Singe power 10-24V ultra-heavy subwoofer preliminal board front is made into a low-pass filter board The main parameters:Power supply voltage: DC10-24V single power supply DC powerFrequency range: 22Hz-300HzAudio input: single -channel or dual -channelAudio Output: Single RoadPCB specification: 78x32mm, thickness: 1.6mmPCB material: ultra-hardness FR-4 glass fiber boardNetburn net weight: 30gThe center distance of the fixed hole of the board: 70x24mm, hole diameter: 3.2mmPoint spacing of the axis of the potentiometer: 32.5mmThis board is a heavy subwoofer front board. It will not sound directly connected to the speaker. You must receive a pure rear -level power amplifier board to make a passive subwoofer to make a sound.The greater the power of the pure -class power amplifier, the more shocking the effect.The so -called low -pass filtering board is a high -sound part of the vocal voice, retaining the low -frequency part for amplification to improve the bass replay, and you will not hear human vocals and high -frequency musical instruments
