Customer Reviews

I ordered a custom 24×4 Neumann v475 A from Mr. Paul.

Delivery to Sydney Australia was fast and the quality is superb. You won’t find nothing like this at this price point. I hook it up with a prism Orpheus and every make senses now,
You get details of your mixing, separation and space, clarity and nice bottom thanks to the Neumann’s that Paul suggest, cause it fits the kind of music I make (acoustic and rock). This is my first summing mixer… I’m so happy and my ears are grateful that a made this decision. 
Highly recommended!!
Mr. Paul keep doing what you are doing cause you are doing it right!!!
Never seen so much passion in product.
Happy customer here!!!

I heard the Neumann Vintage Maker in my room on my system compared to a Dangerous LT and a Shadow Hills Equinox.

The sound card was an Antelope Orion. Granted I was applying these summing boxes to a hybrid mix (mixed through a pair of Pultecs and BAE 10dcs) so these were not summed from the beginning. Regardless the differences were more than obvious. The Dangerous was larger sounding than the Equinox but the equinox was classier sounding. The Lt sounded like a REALLY big ITB mix which could be appealing for some styles. The equinox had nice low end mojo happening and over all but couldn’t touch the sheer size of the Dangerous to me.

The Vintage Maker had more width and a super classy 3d vibe to it that neither had. 

The VM was the clear winner in my book.

Comparison test

No A/B comparison audio tests due to following reasons:       

  • Your studio setup is total different like mine or the others.
  • Completely different mixing strategy, different style, sound and production.
  • Can not be reproduced Your studio environment as inserts, sends, external processors.
  • Can not be reproduced Your studio setup, your monitor types, audio material, pre amp, amp, gain adjustment, cabling and so on..

There are plenty of customer feedback, please read about more…

Haufe / Pikatron transformers

The extremely high level handling of this transformer makes it useful as a line level input AND output in addition to being one of the best sounding  input transformers ever. The Haufe audio transformers used in some of the finest vintage high fidelity and professional German and European audio equipment, including Telefunken/Siemens/TAB/ recording consoles, Klangfilm theater equipment, etc.

The (Neumann/Filtek/Lawo or Tab/Telefunken) dual junction amplifier contains two(2) mutually independent stereo balanced audio frequency amplifiers designed for signal summation in high quality studio mixing desks. Special attention has been given in the design of the cards, to dependability and operational reliability, stability of the electrical parameters, good immunity to disturbance and crosstalk attenuation between the two (L/R) signal paths.

Fully balanced Solid State Discrete summing network. The components are tested and selected. (Vishay Dale resistors) Good quality components result  the correct and low noise operation. The summing network PCB is own development, and absolutely hand made. The front/rear panel design based on unique idea. Custom order: Unique ideas, plans like: channel number, design(your name or studio name) connections (DB25, TRS etc.) please contact me, to make the most appropriate gear for your studio! (build time depend of project size 5-20 working days)

Complete control from DAW mixer

If you want to breathe life into your digital tracks, a summing mixer is the best way to do it. Summing mixers add real analoque harmonics and punch to the sound of your productions, letting you easily mix stems output from your DAW in the analog domain.

  • Fully balanced dual stereo solid state network & switching network from input to output.
  • Can be left “free” unconnected inputs 4-8-12 or more inputs! 
  • No unused/unconnected input problem!
  • No thermal noise on passive mode due to custom-developed balanced summing network.
  • Absolutely repeatability DAW control: Volume Panorama, EQ, and effects sends of your mix from within the DAW, and send as many as 4-8-16 different tracks or submixes to Summing Mixer.

Designed for multi-purpose applications:

  • Instrument balanced/unbalanced signal from synths like Moog, Nord, Yamaha etc.
  • handle large external instruments like samplers, tape machines, drummachines etc.
  • fit to all brand of DAW interfaces like Digidesign 192, Avid HD I/O 16X16,Universal Audio, RME Fireface, Prism, Lynx Aurora, Apogee, Motu, Focusrite, Metric Halo, Steinberg MR816, and so on..
  • external signal processors eg. EQ, Compressor, Limiter, Multi Effects Processors like Massenburg, Drawmer S3, Lexicon, Alesis, Tube-Tech LCA2B, JoeMeek, FMR Audio RNC DBX, ART etc.
  • large number of external mic preamps like AMS Neve 1073,Aphex Channel, Great River, Avalon, Chandler Limited, Crane Song, SPL, Focusrite, Presonus, Midas, Summit Audio, ART Pro and so on…
  • Extremely simple, Discrete, pure, and transparent signal path.

Can be used for external DAW summing or as a line summing mixer for effects, external mic pres, instruments, synths, drum machines or any (balanced/unbalanced) line signal!

Headroom – Dynamic-range space

  • Headroom is how much room has your audio signal before it starts to get compressed and distorted.
  • Headroom – It provides buffer zone for harmonics, transients or loud sounds without risking clipping, which result a more dynamic open and wide, depth 3D sound. 
  • Also it provides space for Gentle Harmonics Distortion. 

Passive side of mixer

  • -25dB insertion loss resistance (gain loss)
  • ideal for both Active (Neumann) and Passive (external micpre) work range

Drive it higher the passive side of summing mixer for more harmonics & transients

  • Generate analog harmonics and hit the gentle harmonic distortion point
  • By proper gain staging from DAW can achieve the Analog Harmonics Sweet Spot

How to hit analog harmonic distortion ?

  • Simply boost up your DAW output Level (master fader) – and you get some “nice” distortion because you’re pushing the summing quite a bit over its nominal level

ACTIVE / PASSIVE 2in1

What’s the 2 in 1 (two in one) Active Passive?

  • this function enables to connect different kind of amplifier
  • freely can use a completely different sounding amplifier than the inside amp

There are two ways to control by A/P switch:

  1. Active mode: gain makeup by inside amp Neumann/Filtek/Lawo/NE2OX
  2. Passive mode: gain makeup by Your external micpres or DAW amplifiers

Benefits: Different amp = Different sound character

free to choose and use completely different sounding amplifier

Master Send/Return:

SEND out the master stereo to external processors like EQ, Comp, Limiter than return to master out

  • 2xSwitch version: Bypass or Enable switching
  • Auto TRS version: signal was non interrupted if nothing connected to SEND out TRS

STM – stereo to mono function

For example you may want to keep the Kick and the Bass in the middle of your mix, you would then flip the switch to UP ST1 to 1/2 for mono conversion
STM function converts signals meant to be in the middle of the stereo spectrum, converts the Stereo input L/R (two hard panned L/R Input) signals to absolute center placed real analog mono signal.

Benefits:

  • no need to waste precious stereo CH’s for mono instruments
  • clarity of position in the stereo field (mono is true mono)

Master Stereo to mono – Mono Compatibility switch

  • This provides an excellent way to check mono compatibility and to also learn spatial tricks from your favourite reference material.

The word ‘Mono’ is panned absolutely center. This means both Left and Right speakers reproduce the same word ‘Mono’ at the same volume. This also sounds ‘mono’ and so panned to the middle.
Checking your mix for Mono compatibility as you go is a good preventative measure. Sometimes just because a mix sounds good in stereo doesn’t mean it will sound good when the left and right channels are combined into a mono signal. In some cases, you may hear what is known as comb-filtering, which will color the sound of your mix and cause peaks and dips in its frequency response. In some cases, instruments may lose their integrity or even seem to completely disappear from the mix!
