FOUR CHANNELS MIC PREAMP MP312-4
©2019 WWW.AVDAUDIO.COM
Preamp PCB has four same channels. All channels are identical. Manual shows building
of one channel only. Build other channels by the same way. Others important moment
will show you separately.
Let’s start main PCB!
Solder all resistors and diodes.
Each channel has one diode 1N4004 and eleven resistors. Next nominal of resistors you
can use per channel: 160R, 200R, 510R, two of 750R, 5K1, two of 6K98, 10K, 20K, 150K.
Do the same on each other channels!
In the end of this step you must solder two diodes 1N4004 on the power side of the
board! You can soldering two power capacitor (100uf/50v) this step as well. Or soldering
as we do it after! But it helps you to do this easily now!
