HEADROOM AND SEPARATION ALWAYS perform in the Passive summing network!
1. HEADROOM - 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/with hotter levels" (from your DAW interface or synth, drum machine etc.) Need to find the right high/hot gain for all your instruments/track sent to summing box individually, the "gentle 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 - 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".
Use your Mic PRE or Line amplifier, to get a wide tonal character by allowing you to choose your flavor of make-up gain.
The simplicity of the fully balanced, symmetrical signal path allows the use of no-compromise passive components for an absolutely transparent signal path!
Plug into your mic preamp, or old Telefunken or RCA tube preamps to work when you want super thick warmth!
Fully balanced analog line mixer, can be used for external DAW summing or as a line summing mixer for effects external pres, instruments, synths, drum machines or any (balanced/unbalanced) line signal!
Chances are your mic preamps or line amps, just sit there unused at mixdown time anyway, so put them to work!
Let me know about TYPE/BRAND of Your Mic pre or interface Mic pre / Instrument, to hit the best impedances of your passive summing.
different resistance level need for Neve1073, Avalon etc (+40dB - 65dB make up gain)
different resistance need for DAW interface like Focusrite, Motu etc. (+10dB - 35dB make up gain)
Passive analog line mixer, can be used for external DAW summing or as a line summing mixer for effects external pres, instruments, synths, drum machines or any (balanced/unbalanced) line signal!
The Passive Discrete Summing is therefore able to assume a wide variety of tonal character dependent on your choice of amplifier (mic pre)!
This signal is ideally suited for feeding into an outboard microphone preamplifier of your choosing.
The Passive Discrete Summing has an extremely simple, Discrete, pure, and transparent signal path. No faders, EQ, aux sends, pan knobs, or any other superfluous features allows for an entirely passive circuit. There are no amplifiers, ICs, transistors, capacitors, or transformers in the signal path!

Selected Vishay Dale metal-film resistors
NOISE FREE TOPOLOGY!
Input impedance: 10K, 6.8K, 4,7K or 2K ohms balanced (depend of Your preamp type)
