Filtek 32×2 Summing Mixer
Filtek vintage summing unit – UK.
Custom designed 4- 96 input channel mixers
No compromise control from DAW
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 application:
- 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!
Transparent amp, with nice harmonics as a result of legendary Haufe transformers.
If you want colour:
- Add an EQ for colouring.
- Adding tone can massively redefine the tone of mix, and sounds really cool..:)
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..
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.
“Gain staging is like pulling the focus of a camera lens”
You can achieve this by entering in the summing unit by higher levels” (from your DAW interface or synth, drum machine etc.)
Passive mixer side
- -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 to achieve 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
