Microphone Vu Meter Circuit LM3915

VU Meter circuit with LM3915 has a lot to do with this circuit based on the difference between the ambient sound from the burning of LEDs speech, müzük, television, etc.. VU Meter circuit as compared to non-working microphone sound output of the TDA2822 amp is being upgraded with integrated LM3914 50k potentiometer input is given to the sensitivity can be adjusted. LM3915 and LM3916 LM3914 can be used instead of a printed circuit board “sprint layout” prepared with 10 ultra-bright blue LEDs are used looks just fine ..

RMS 2X200W Amplifier Circuit MJL21196 MJL21195 2X200W transistor amplifier circuit The aim of this bachelor thesis was to design a low frequency power amplifier for speakers for the purpose of sound public events. Its use therefore determine addressed the concerns of the processing, where required by the supply of sufficient power (at least 200W per channel into a load of 4Ω) for four odposluchy serving musicians, DJ, bands, singers and others. His proposal demanded high-quality processing, as the custom filing sound for the musician it must be sufficiently loyal and quality, so that it could assess whether to improve. This work addresses the complete involvement of of the amplifier and thus contains the analysis of the individual blocks as they are the ac power source, the preamplifier, the amplifier stages but also the module spds speakers and amplifier.
