Adding transformer saturation

to your audio material or for your existing passive summing mixer in order to enhance warmth depth and color. This process involves using transformers to add harmonic distortion, which can lead to a warmer, more vintage sound with increased depth and richness. The saturation effect can also contribute to a more colorful sound with greater tonal complexity.

Customer reviews:

I had the opportunity to test the custom desktop Neumann V457 which was specifically designed by Paul to integrate with my existing LittleOne Desktop Passive Summing Mixer. I must say, I was quite surprised by its performance. The harmonics produced are simply stunning, giving recordings a sense of warmth and character that is unmatched by other devices in its price range. The mix is glued together, but at the same time, individual instruments are separated and clear. Overall, I was thoroughly impressed with the custom desktop Neumann V475-2C. It demonstrated excellent craftsmanship and design, and it certainly exceeded my expectations in terms of performance. I would highly recommend this device to any audio enthusiast or professional who is looking to enhance their existing mixing setup. The addition of this device is sure to take your audio productions to the next level.

I am absolutely overwhelmed by the stunning harmonics produced by this device.

The warmth and character it adds to recordings is truly unmatched by other devices in its price range. Moreover, the mix is expertly glued together with separation and clarity, which is truly awesome…

The four (4) in-out Vintage Haufe German transformers provides incredible clarity and warmth to my recordings

and with my passive summing (built by vintagemaker) capabilities make it easy to get the perfect mix. The line amp and color box functions also add a unique character to my recordings, giving them a professional and polished sound.
One of the things that really impressed me about this device is how easy it is to use. The controls are intuitive and straightforward, making it easy to get the exact sound that I want. The compact size of the device also makes it perfect for my desktop setup, as it doesn’t take up too much space.
Overall, I would highly recommend the 2×2 Desktop Neumann V475-2C to anyone who is looking for a high-quality piece of equipment for their recording studio. It has exceeded all of my expectations and has quickly become an essential part of my setup.

Wide and Warmth panoramic space, real analog console like sound! Testing of the Desktop Neumann summing was very nice! Now I know what you told me come true!… Every Track has it‘s Own Space now… and some Kind of warm silky Sound… excellent!! Thanks paul!

Warmth fat 3D sound, extra low noise with excellent unique high sound quality- Audio Transformer Color Amp

As customer and studio producer, I have been using the 10 input Desktop Neumann for a few months now, and I must say I am thoroughly impressed with its capabilities. The 2 input TRS 1/4″ Balanced (AUX Line In) and 8 input DSUB Tascam (summing) options give me a lot of flexibility when it comes to connecting my equipment.


The dual 21 step precision vol control L/R and dual stereo independent amps L/R make it easy to control the sound and levels of my mixes. The external power supply ensures that I get the best performance possible from the studio producer. Additionally, Audio Transformer Color Amp come with the 4 x Haufe in/out transformers and the +30dB gain range (AUX) divided into a 21 step control make this studio producer truly unique.
One of the standout features of this studio producer is the built-in 8 ch summing mixer. It has proven to be a valuable tool for my production needs. The transformer amp is also a great feature that allows me to track in stereo or mono, depending on my requirements.
I particularly appreciate the master bus color saturation purposes, which gives me a lot of creative control over the final mix. The unit is also time-tested, and its ultra-reliable quality circuit design is a testament to its durability and longevity. I have had no issues with it so far.


The warmth, fat 3D sound, extra-low noise, and excellent unique high sound quality

make this desktop studio summing a great addition to my production setup. It has definitely enhanced my workflow, and I am happy with my purchase.

As home studio producer, I have had the opportunity to work with many different summing mixers.

This desktop Neumann summing mixer with 10 input channels and 2 output channels is one of my favorites.
The 8 input DSUB Tascam summing channels combined with the 2 input TRS 1/4″ balanced AUX line in channels allow for plenty of flexibility in routing and summing. The 21 step precision volume control and dual stereo independent amps provide precise control over the levels and dynamics of the mix. The built-in 8 channel summing mixer and the 2 Haufe in/out transformers help to add color and character to the mix. I especially appreciate the master bus color saturation purposes which allow for even more creativity in shaping the sound. Overall, this summing mixer has a time-tested ultra-reliable quality circuit design that delivers exceptional sound quality. The fact that it has been in production since 2010 is a testament to its reliability and longevity. The ability to customize the name/logo adds a nice personal touch. I highly recommend this summing mixer for anyone looking for a high-quality, versatile, and reliable solution for their mixing needs. I highly recommend this product for anyone looking for a warm 3D sound, extra low noise, and excellent unique high sound quality.

Recently purchased a similar 1U 19″ Rack with 2 Input XLR Balanced L/R and 2 out XLR Balanced from Paué vintagemaker

and I couldn’t be happier with my decision. The Neumann Active/Bypass switches are a great feature, and the Dual 21 Step precision vol control L/R and Dual Stereo Independent amps L/R make it easy to achieve the exact sound I’m looking for. I was also impressed with the 4 x Neumann vintage Haufe in/out transformers that came with it, which contribute to the unit’s +30dB gain range (AUX) divided to 21 step control and Transformer Amp – 1xStereo or 2xMono tracking.

One thing I really appreciate about this unit is its Master Bus color saturation

which adds warmth and richness to my sound. I was happy to find that it was tested and perfectly matched in level and sound, and the time-tested ultra reliable quality circuit design ensures that it will last me for years to come. I also love that I was able to add my own custom name/logo to the unit, making it truly my own. Paul clearly knows what they’re doing when it comes to creating high-quality audio gear. Huge thanks to paul vintage maker.

The inclusion of 4 x Haufe output transformers is a huge plus, as it contributes to the unit’s excellent sound quality. The Neumann Follower circuit is another great feature, and I’ve found that it helps to minimize noise and distortion and adds really huge harmonic mojo…
One thing that really impressed me about this unit is how well it was tested and perfectly matched in level and sound. This shows that Paul takes quality control seriously and ensures that every unit they sell meets their high standards. And speaking of high standards, the time-tested ultra reliable quality circuit design is truly impressive.
Overall, I highly recommend this unit to anyone looking for a reliable, high-quality piece of gear that will help take their recordings to the next level.

I can say that this unit from Paul is a top-notch piece of gear.

The 21 Step precision vol control is incredibly useful for dialing in the perfect level. The +35dB for line instrument, guitar, mono synth or any mono signal transformer saturation
The 2-channel color amp has its own resistor network (similar to a multi-input summing mixer), it offers you a safe zone known as Headroom. Through proper gain staging, you obtain the fundamental harmonics on the device inputs, (due to over nominal level on inputs you get some “nice” distortion) and subsequently route them through the transformer. Here, the tranfsormer amplifier adds extra excitement and enhances the complex harmonics, resulting in a warm analog color character sound. Of course a 4 or 6 or 8 (or more) input summing before the transformer is better from the side of the analog separation panorama field.
