Microphone amplifier M219.1 Modul
Original price was: €7.00.€5.00Current price is: €5.00.This module is a microphone with a built-in preamplifier, which has a good amplitude-frequency characteristic and high sensitivity.
Such high characteristics are achieved due to the electret microphone used in the module.
Thanks to the built-in amplifier, the audio signal can be transmitted via shielded wires up to 20 meters long. The module contains a voltage stabilizer, so it can be powered from a non-stabilized source with a voltage of 6…15 V. -
Stereo sound equalizer 5-band K266 KIT
€25.00This is a DIY soldering kit. For comfortable listening of audio phonograms, it is necessary to change the timbre of the sound at different frequencies. This is related to acoustics, room parameters, individual taste of a person, etc. This equalizer is intended for this, which allows you to smoothly change the frequency characteristic of the sound signal. Regulation is carried out by five bands of double potentiometers R7-R11. An equalizer is connected between the preamplifier and the power amplifier of the audio path. Two LA3600 chips are used as active elements. The output of the equalizer should be connected to an amplifier with a general volume control.

Stereo sound equalizer 5-band M266 Module
€29.00For comfortable listening to audio phonograms, it is necessary to change the sound timbre at certain frequencies. This is due to the acoustics, room parameters, individual taste of a person, etc. This equalizer is designed for this purpose, which allows you to smoothly change the frequency characteristic of the sound signal. Adjustment is carried out in five bands by dual potentiometers R7-R11. The equalizer is connected between the preamplifier and the power amplifier of the audio path. Two LA3600 microcircuits are used as active elements. The output of the equalizer should be connected to an amplifier with overall volume control.
