0.5 F universal capacitor with short circuit protection, reverse polarity protection and digital voltmeter. These devices are indispensable elements of loudspeaker systems that help prevent damage to components in the event of power surges and extend their life.

The occurrence of drops in the standard network is a fairly frequent occurrence when reproducing instant bass impulses, an electrician is in a stressful state during this period. The amplifier is not able to cope with the declared power, at these moments it consumes three times more energy. The battery cannot supply the required amount of voltage. As a result, electrical or acoustic distortion occurs, mid and low frequencies are reproduced with noise, speakers, and the amplifier or subwoofer itself may be damaged.

A capacitor stores energy and, if necessary, transfers it to an amplifier so that it can easily overcome the impulses. It improves bass response, sounds are reproduced in a "purer" form, and the life of the acoustics is significantly increased.

The unit comes with mounting hardware, sealing washers, screws, clamping wrench, and a user manual with detailed mounting instructions. For best results, place the capacitor closest to the amplifier.
