Customer feedback / Germany 2021 feb
After having spent many days considering and reconsidering the choice of analog summing device I want to invest my money in,
I stumbled upon Paul’s little shop and read the countless mindblown-customer reviews.
Having a vague idea of which features were interesting, I contacted Paul, who responded incredibly professional.
His input and feedback was much welcome and supporting for the final decisions.
The updates about the progress were an awesome way to watch my baby being built :D. Upon arrival the built quality and personalized engraving made me smile, but not as much, as the sound!!!
-> The truth is: Whether you believe in it, or not, analog summing (especially with such outstanding components) imparts the 3rd layer of dimension, I’ve always been looking for, but never quite got through digital…
Anywho, the Neumann V475 really imparted a whole new world of possibilitie into my studio and music universe, for much less
money than the “industry standards”. And the recallability is just the icing on top 😉
If you’re considering, I wouldn’t hesitate, the gains are endless. Cheers, Dan from Germany

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!!!
2U Neumann 2A 16x4 with stereo insert
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)

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

STEREO TO MONO
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:
- Active mode: gain makeup by inside amp Neumann/Filtek/Lawo/NE2OX
- 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
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!
