Paul makes some amazing high quality summing mixers.

I’ve owned the Dangerous 2 Buss and the Roll Folcrom, and this easily holds its own with those units.

The real deal maker is that you can get a custom built one that suits your exact needs. The international shipping was very fast to the West Coast USA, and the build time was within a week for my specific custom needs.  I’m so glad I came across Paul’s stuff. Definitely a great choice!!

These days the analog mixing technique has shifted mostly to the passive summing part.

Let me explain. It’s more easy and more convenient to switch between different external amplifiers like Neve, Lawo, Avalon, API, Focusrite and so on, besides of internal (built inside) summing amplifiers. Therefore by external amps you are NOT forced to use always one type of amp what you have inside of your summing mixer, finally you know – different amp = as a result for different sound colour and character.

16 input Summing mixer custom designed for PreSonus Studio 192 Audio Interface with four (4) Master insert send returns, variable gain switch and stereo to mono conversion switches

Coloring or not coloring amp that is the question

Well, you can use a really warm tube amp for sound colour, or a really transparent non coloring amp for clean sounding, that’s your choice, and depend of your audio material. IMHO my customers really don’t like to change their mix character. On the other side the nice and pleasant harmonics can make the magic on your music.

btw — add an EQ for coloring / adding tone can massively redefine the tone of mix, and sounds really cool..:)

So no problem at all If you do not have expensive microphone preamplifiers, You can use for gain make up Your existing DAW Mic Preamps or instrument line inputs with GREAT success because you will get a custom built passive summing mixer designed for your preamps work range.

Why Passive Summing mixers (have) gain loss?

As all analog mixers as well the passive summing network need to have summing resistors placed on channel inputs,due to those

(Vishay Dale) resistors  provides load isolation and improves channel to channel isolation.

The point is, it couldn’t be summed different instruments without resistor (gain loss) isolation, if you try to do without resistors as result you get over 0dB, furthermore you get clipping above 0db actually cause worse audio quality…

The gain make-up amplifier like an External amp — your DAW mic preamp or line amp or Internal transformer based amps like Lawo or Filtek or Neumann which follows the buss (master stereo L/R out) compensate the gain loss of passive summing mixer.

 

 

Can I use my DAW interface “stock” mic preamps or line input’s for gain makeup?

Yes, you can.

By prior consultation the mixer will be designed for your DAW mic preamp working range, so you can use your DAW interface mic preamp without any compromises.

Gain loss — Gain make up

It is important to note that the gain range (eg. you have +30dB gain up relative to 0dB) of your DAW Interface (preamp, line inputs) will determine the passive summing resistor values, therefore You need to tell me (furthermore I need to know) your external gear gain make up range.

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages and so on…. so due to those resistors we have gain loss on the summing bus.

Behind the former example: 

-15dB gain loss summing with +30dB to +40dB preamp = perfect “middle way” ratio

The other passive mixers on the market come with huge  -35dB to -40dB gain loss, which requires +50 to +60dB gain make up, which in my humble opinion is meaningless, and it requires expensive preamplifiers, but if you have them, you are a lucky man:)
For example customers with -25dB gain loss summing use +50 dB to+60 dB  range gears like Neve 1073, Avalon etc. with great success based on  customer feedback since 2010′.

Gain make up requirements – let me know before you make an order

*Basic Setup -15dB by default please let me know if you need different gain structure before you make an order.

  • MINIMAL:  -6,5 dB or -10dB relative to 0dB

  • LOW:  -15dB gain up  ideal for entry level preamps or DAW mic pre or instrument input

  • MID:   -20dB gain up  ideal for mid range preamps or DAW mic pre or instrument input

  • HIGH: -25dB (or more) gain up  ideal for high range preamps like Neve, Api, Avalon or DAW mic pre

Flexibile solution:

Variable gain switch: -10/-20dB, -15/-25dB or -25/-35dB read more….

Customer Reviews

Cr Jeffrey McLaughlin

I have been working with Bob Katz doing the mastering.

I want to share this quote from Bob.

“Things are a lot sweeter! Compared to the previous mixes this overall sound, including the vocal, is like milk and honey! Overall with better balance and natural tonality. The sound has very nice dynamics and impact. It’s a total transformation. Good clarity, instrumental balance, stereo image…
Feel free to use the +18 setting or even a hair higher if available as your peak level does not exceed -5.6 dB.”  Bob Katz 

This is to the Dr Flouride Mix 24 summing mixer you made thank you. It’s letting me do world class work in a very remote environment 

Herb Belofsky  Drummer · Austin, Texas

My REVIEW: Clarity and Glue.

It clearly sounds better than in the box summing, but you all knew that would be the case. It also sounds better than the AMEK console that I had been using for summing mixes. I had sold the console and this was one of the replacement parts. I am Very Happy. I would highly recommend Paul Taylor’s custom built products. he was easy to deal with, great communication and ultimately a great sounding box that let me interface the preamps I already have as the 2 buss. A serious upgrade for a box that is reasonably priced for what it does. I would love to hear the other active summing mixers that he makes, but for now, I am a happy studio owner with the box he sent me.

Thanks, Paul.

Passive Summing 10x4 TRS/DSUB designed for UAD Apollo Unison Preamps Insert Focusrite ISA828

Gearslutz review

I have been mixing for about 15 years now and all my mixes have been done in the box.  I work hard to get the harsh digital sound out of each track.  Using plugins like Oeksound’s Soothe, UAD Studer Tape, Oxford Inflator and others to bring some analog beauty to my mixes.

I have heard about analog summing for years.  Fab Dupont highly recommended it on one of his Puremix tutorials.  But I have heard other mix engineers like Andrew Scheps say he doesn’t use any analog gear when mixing.  So I was skeptical of spending my hard earned money on something that “MIGHT” work.  So I never did.  Until just recently when I came across a few Vintage Maker videos.

Actually it was the price that drew me in.  I thought that it would be worth the risk.  I mean I spent thousands of dollars on plugins that I thought would make my mixes more Analog in nature.  So what the heck.

I contacted Paul at Vintage Maker and told him my setup.  I have a UAD Apollo Quad.  He sent me all the info I needed.  He even made me my own personal visual direction sheet and custom made me a unit that would fit my needs.  I don’t know how many emails we sent back and forth but a lot.

Anyway, when I got it and plugged it all up-  I was stunned.  It’s like I got a whole new system.  My mixes went from trying to fix all the harsh tones to almost having to brighten some of the tracks up which is a good problem to have for me LOL.
I wish I had done it a long time ago.

It’s not a mind game thing.  It really changed what I can present to my customers and to myself.  The 3d Stereo Imaging that I’ve heard people talk about is true (especially on the effects). The sweet warm sound makes me want to listen instead of running away from the piercing darts of a sharp lead guitar solo or female vocal. 
The customer service and the absolute transformation of my mixes is well worth the $500 I spent.  I am a believer.  Thank You Paul and Vintage Makers!!!
