Legendary Neumann - Lawo - Filtek transformer summing amplifiers in new skin!
When mixing on a computer, many prefer to sum the tracks in the analog domain, which can result in more depth of field and a wider, more defined stereo image. The people who prefer analog summing, most would not use the word "clarity" to characterize what's better about it. I hear phrases like "more depth and separation," or "more rounded/warm low end," etc. It's really a personal preference thing, and probably driven to some extent by what you are used to hearing when you work.
The analog domain offers a number of great advantages compared to the simple "bounce-function" within your DAW. While a digital system rounds off all values for level, pan, eq-ing and compression, analog technique operates with an infinitely high resolution, causing no rounding errors or digital distortions.
A sound engineer described as follows: the digital mixing is a mathematical summing, like 1+1=2 (exact 2). Mix in analog domain :1+1=2,05 (because summed as sinusoidal voltages) + adding beneficial effects of harmonic distortion and transformers result the pleasant harmonics, rounds, transparency and more spatial depth. Of course, in analog, every system sounds different - in some cases significantly different.
1. HEADROOM - always perform in the Passive summing network.
"Gain staging is like pulling the focus of a camera lens" You can achieve this by entering in the summing unit by higher hot levels" (from your DAW interface or synth, drum machine etc.) Need to find/hit the right high/hot gain for all your instruments/tracks sent to summing INPUTS - hit the "gentle harmonics distortion" point, where the subtle distortion starts gently and it's about right. It basically impossible to do that ITB [In-The-Box] over 0dB starts to distort during gain staging, simply the digital bounce not allow to send hot (high gain)
2. SEPARATION - Panorama - always perform in the Passive summing network.
Find for all your instruments the right places in to the stereo field, the right locations where they sit better in to the whole mix. Don't forget - your instruments are mixed in the analog domain as sinusoidal voltages!
3. MAKEUP GAIN - Gain staging - Drive the amp!
Make up gain "crank it up" - make up gain by your mic pres or internal summing amp, and hit the sweet spot of master mix, then print/record.
It's important to find the sweet-spot when the level and subtle distortion is just about right, depending on the song and production. ITB has no sweet-spot and there's really no reward running the levels a bit too hot, on the contrary is even makes the mix sound worse.
US customer review
"I was used to mixing in the box, and I knew my way around it. You always need to make more room. I realized I wasn’t doing that anymore, and was not needing many of the tricks I used to do to get closer to what I was hearing in my mind, so I wanted to learn how much headroom I got. I fed my converters with the hottest signal in the center of the panorama and started automating the faders around it. Soon enough, the magic happened: the summing box started purring like a happy big cat and I knew that was the sound I always struggled to reach, the famous and legendary “warmth and openness of analog” I so many times read about. "The analog sweetspot".

Passive summing network = SEPARATION = "wide" or 3D - deep effect come from summing network. The integrity of the stereo panorama is more defined, more separated, much more panorama positions. Best results panoroma positioning can make/set during analog SUMMING - mixing! There are no 0’s and 1’s but only voltages. These are complex sinusoidal voltages that include the harmonics and other elements. Many engineers consider this to add the “warm”, “in-depth” and nice separation sound you get from analog. (Emerson R. Maningo)
Active summing by amplification= SEPARATION (from passive summing) + WARM HARMONICS - during transformer/or/discrete OPAMP based VCA MAKE UP GAIN. (Neumann amp: Haufe /Pikatron xformers, or external your MicPreamp or Amp gain make up)
All analogue summing boxes sound different and it's important to find the sweet-spot when the level and subtle distortion is just about right, depending on the song and production. ITB has no sweet-spot and there's really no reward running the levels a bit too hot, on the contrary is even makes the mix sound worse.
Gain staging is like pulling the focus of a camera lens
ANALOG SUMMING give the possibility to make the best sounding of Your music, by mixing and listening in ANALOG, all your stems from your DAW or SYNTH, DRUM MACHINE, SAMPLER etc as original complex sinusoidal voltages that include the harmonics and other elements (SEPARATION and WARM) "listen in analog what u mix"- find the right place of your stems, make panorama and gain modifications in analog...than make up gain - hit the the sweet-spot when the level and subtle distortion is just about right by internal legendary Neumann or Lawo summing amps or other external amp like your mic preamp or DAW INTERFACE MIC PRE/INSTRUMENT input, moreower insert to master chain by Insert/Send/Return Bypass option an external EQ, Comp, Limiter or other outboard gear for signal processing purposes... More mixing will help make your mixes better. Remember, You are the X- factor - the summing box is a useful tool, in skilled hands can make the "Magic".
***The more channels you mix analog, the bigger the difference. Also the more you do to them in the analog domain, the bigger the difference. You then perform only the summing in the analog domain. This enables you to maintain absolute repeatability from within your DAW. With vintage summing amps (like NeumannV475, Lawo etc) the summing bus become a solid state active mixer. (gearslutz)
*excellent for acoustic, classical, jazz, blues, blues-rock, classic-rock, folk-rock, country, ballad, bluegrass etc.
NE2OX A2E / A7E - Transformer based dual stereo summing amp with variable frequency mod Dark/Flat/Air
The (Neumann/Filtek/Lawo or Tab/Telefunken) dual junction amplifier contains two(2)STEREO (dual stereo)mutually independent 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.
No A/B comparison tests due to following reasons:
Every studio setup is different, due to different mixing strategy, different point of view, style, sound and production, I can't reproduce Your studio environment, your studio setup, your monitor type, sound, preamp, amp, gain adjustment, cable, and etc.
