Product Detail
For DIY enthusiasts, now really inconvenient to use, after all, easy to find a single power supply, dual power to get up more trouble, to ensure the effectiveness of the premise, we have developed a
single-supply low-pass filter
plate can be directly and amplifier using a set of power sharing is very convenient, welcome everyone to buy, what are the strength of our school, and the use of very standards.
Performance parameters:
(A) innovative use of a single power supply and power amplifier board can share power, very convenient, the op amp using
NE5532
, welded op amp IC holder, easy to replace the op amp to enhance playability, and all are Philips CBB capacitance capacitors, potentiometers uses high-quality sealed units produced potentiometer.
(B) with a full-range signal to adjust the volume potentiometer, very convenient to 2.1 amplifier board preamp.
(C) The LED monitor real-time power status.
(D) Dual-panel design, and strive to simple signal transmission, signal to noise ratio is very high.
(E) Input voltage:
DC10-24V
.
(F) can be a single / dual-channel input and mono output.
(G) PCB ultra-hardness FR-4 fiberglass board, board size: 82x30mm, excluding protruding parts, thickness: 1.6mm.
(H)
frequency adjustment range 22Hz-300Hz
, this frequency range is not the human voice, so-called low-pass only low-frequency output, to be added after stage amplifier power amplifier board can be used. The intensity of low-frequency performance with power amplifier board and speakers match, please choose a different amplifier board and subwoofer (passive subwoofer) according to different occasions.
