Some catching up...

First, an overview and introduction.

I created this blog to document the building of my rotary mixer. The heart of this mixer lies in the boards designed by Bozure. Pern (Bozure is just 1 man) designs modular mixer PCBs that allow for pretty much the highest degree of customization imaginable, as the boards basically just provide a core functionality.

Bozure's circuitry is inspired by the Bozak and Urei rotary mixers of days yore. I am basically putting that functionality into a 4-channel desktop rotary mixer, with no bells and whistles and very high sound quality.

This mixer uses the 3 boards from Bozure's M1 project - 1 main audio board, 1 cue system board, and 1 power supply board which converts AC to +DC and -DC. For the most part, I am following Pern's own recommendations for components in this build, including using ALPS RK27 potentiometers which are probably the highest cost in the whole project. In addition to the Bozure boards, I am using Velleman K4305 PCBs for the LED VU meter (available as a kit), and future plans include phono preamps and bass EQ for each channel, both of which are still in development from Bozure). I plan on assembling the mixer and getting it operational as soon as I have the phono preamps, and adding EQ later. Eventually, having an isolator might be nice as well.

A bit about myself: I am an amateur DJ ("bedroom beats" if you will) but am very into the hobby. I like mixing various types of house, techno, disco / nu-disco, etc. I'm not going to be doing quick cuts or scratching on this mixer. I'm building it because I always wanted a high-end rotary mixer but couldn't justify the $1000+ expenditure. What I'm building isn't exactly cheap, but it's definitely in a different price range. I have some experience with doing some small electronic projects when I was younger (playing with phones, re-wiring a guitar or bass or two, just fixing little things), but I don't have a serious background in electronics or anything. Just doing this as a little (or maybe not so little) winter project.

Anyway, I'll update with pictures soon, hope you enjoy reading this blog.
