All About Mixers

Welcome to the All About Mixers WebSite.
This website is my creation in response to the poor information availiable on the world wide wasteland we all call the world wide web. I have been building "custom Mixers" and consoles for over thrirty years. I have built consolettes for Broadcast stations and home recording studios. In the early 70's (the 1970's) I built high-power custom amplifiers for rock-n-roll bands in Nashville Tenessess. My amplifiers where nick-named "Nose Bleeds" because of the soundpressure that they were capable of delivering. I personally stipulated that the speaker arrays were to be mounted high up on the riggings and a minimal of 12 feet above the crowd with the speakers oriented to radiate over the crowds to prevent unnecessary ear damage. But my warnings almost always went un heeded, and rockers being the rebels that they were - they usually mounted the arrays directly towards the crowds.

Crowds at the Battle of the Bands events in Nashville,TN, Birmingham, Al, Tupelo, Ms, Memphis, Tn, aned Jackson, Ms were always getting nose bleeds from "my" amps, even though I constantly pointed out that they were being incorrectly applied.

Needless to say - My amps were banned from "Battle of the Bands Events" starting in the spring of 1975. A few enterprising Bands went as far as to rebox the amps - but were often caught and removed from competition.

One enterprising Individual from Brentwood Tennessee (his father was a Grand Ole Opry Star) even went as far as to encase my amps into a Fender Case - Which I found really strange (and funney) since my amps were transistorized, and the Fender Case was a "Tube Amp".

Oh wel... At least alot of my mixers and audio processors survived the banishment tribunals.


This web site is dedicated to the "Analog Audio Mixer".

Analog Mixer Theory and Practices will be discussed along with practical examples when possible. (You must remember that many really good mixer designs are still trademarked and copyrighted to this date). When I can I will provide real schematics, and for the enterprising I will also try and include artwork for Printed Circuit Board Fabrication. Naturally, all the PC Boards can be ordered from me (since I have all the artwork and PCB Blanks anyway).


There is a schematic Section where you can find your favorite (or soon to be favorite) schematic.


There is a Printed Circuit Board ArtWork section where you can find the PCB Artwork to help you lay out your own PC Boards to "Make Your Own" if you are so inclined.


Naturally A section is provided where you can learn to make your own Printed Circuit Boards. What hobby site would be complete without this area??? You will naturally find links to "my" favorite PC Board Fabrication Supply sources.


The final section will be the "Projects" section. What hobby page would be complete without a "Projects Section"??


Last, but not the least - I have included a Links Section So you can do your own research and browsing. Besides this allows me to legally include other "excellent" designs created by other industrious individuals without the issue of wheter or not they are "my" designs. After all, the overall goal is "All About Mixers" not "All about dave's Mixers" - Right?
