This kit creates a microphone amplifier with an output suitable for stereo headphones. With the kit, it will be possible to amplify any sound in the environment, from voice to common noise from objects and/or music, allowing you to listen to it amplified through the headphone output. It will also be possible to adjust the amplification using the trimmer RP1 to achieve the desired volume. The device does not have frequency cuts, so any sound will be amplified. Soldering is required for assembly. The kit comes with assembly instructions in English.

| How it works | |
| It can happen to find oneself in situations where the capabilities of one's hearing are not sufficient, or where one wishes to listen to noise coming from a distant area or a voice from afar; in such cases, a device like the FK019 can be useful. The circuit is essentially composed of a microphone that picks up sound, which is then amplified through a transistor circuit, and then further amplified to the right levels to be listened to through common headphones connected to the 3.5 mm "Audio out" jack. Volume adjustment is done by manipulating the RP1 trimmer. The device must be powered by a CR2032 button battery. The power can then be supplied/disrupted at any time through the S1 switch, allowing it to be used as needed, thereby extending the battery life. | |
