Cara memasang preamp mic pada amplifier‼️pasang preamp mic untuk karaoke

for this video how to install a mic pre amp/mic amplifier on an amplifier, for the voltage input to the mic pre amp follows the main power amplifier psu, the voltage is lowered using a 100 ohm 2 watt resistor and a 7812 regulator ic, and the input voltage to the mic pre amp is also combined with a non-ct tone control and a bluetooth mp3 module. For a video on how to assemble a PSU voltage reducer for power to the tone control and MP3, see the video link below:    • 🔴pasang mp3 bluetooth pada tone control no...   The resistor for the mic preamp output can be 1k-10k, which affects the sensitivity of the mic. It's up to personal preference. tags: installing a mic preamp to an amplifier, installing a mic amplifier to an amplifier, installing a karaoke mic amplifier to an amplifier, mic preamp, mic amplifier, power amplifier, karaoke mic, assembling an amplifier, assembling a power amplifier, installing a tone control to a power amplifier, installing an MP3 to an amplifier, installing an MP3 module to an amplifier, #preAmpMic #penguatMic #mickaraoke #electronic #poweramplifier #audioamplifier #stereoamplifier #amplifier #assemblingpoweramplifier #sound #installmp3bluetooth #installtonecontrol #assemblyamp #amplifier assembly #modulmp3bluetooth #rissaudiotech
