Dear DIY enthusiast!
This guide will help you assemble and test the 1290 type microphone preamplifier. For those not familiar with it, it is the famous RN73 type preamp, but without line input and equalizer section. This allows those on a budget to get "that famous sound" and still save some money for other gear.
This module is the part of our 4-channel frame system and is intended (but not limited) to be used as a part of that system. However, this should not stop you if you want to put the 1290 module inside your own enclosure - it is absolutely possible.
Please note: access the Guide will be provided with the 1290 PCBs set.
