Customer feedback – What Engineers Say
“Hi Paul, I’m Aleix! And yesterday I was testing the discrete summing Filtek bfe! And I liked very much! Yesterday we tried it in my studio with a Digi 003 + Converter RME ADI 8 to have 16 tracks for summing! The Filtek is very clear, when mixed, it is very easy, because once everything is in place, treble and bass are more clear! These Neumann-Haufe transformers are awesome! tried the SPL MixDream and Neve. And I love the SPL! But after testing the Filtek, both quality and price is amazing !!!!! So I like this new Filtek you’re building!” – Aleix Arcs from Barcelona
“I’ve bought one summing mixer from 3 months ago and I’m really happy with its sound (it is Filtek BFE option). This box does exactly what all consumer multichanel audio interfaces lack. I’m currently using it with M-audio ProFire 2626. What I would like to say is that this guy is real and he’s making very nice equipment out there. Besides, he is very approachable and helpful regarding all questions and inquiries.” – Andrej Busch
“+1 to the above posts. I got the filtek 16 channel version to use in a fully treated project space at the beginning of the year… throw in a pair of ensembles and set focal twins and … well lets say this ‘compact’ set up blows clients of all genres away… Full stop. The clarity, imaging and tonality is simply astonishing for the outlay. An aural pleasure . If you are itb, got some nice valvie toys (and understand analogue gain staging within a daw – its amazing how many don’t!) and want to get the rich and silky console joy this is the best 500 quid you could possibly spend….IMHO (ok sprinkle a healthy few k for the other bits!)” – Gearspace verified customer
Looking for more harmonic density at a lower price point? The Filtek-Neumann SSL-Style and Lawo API-Style also use genuine Neumann-Haufe transformers and deliver comparable harmonic performance.

Frequently Asked Questions
Are the transformers genuine Neumann-Haufe?
Yes — the Filtek BFE DV1175 is an original broadcast console amplifier module fitted with genuine Neumann-Haufe transformers. These are authentic modules removed from large-format European analog broadcast consoles, using the same transformer technology found in classic Neumann console modules such as the V475 and U473A. No replicas or modern reproductions are used.
How does the Filtek compare to the Neumann V475?
Both use genuine Haufe transformers in a discrete topology — the DV1175 is widely considered the Swiss equivalent of the Neumann V475. Its harmonic character is comparable to the Neumann V475-2B variant, which is why the DV1175 is often regarded as a successor to the V475-2B design.
Does the Filtek require external gain recovery?
No — the Filtek DV1175 has an integrated discrete gain stage. External makeup gain is not required, though using quality external preamps adds additional tonal character on top of the transformer sound.
Can I order a custom channel count?
Yes — available in 4–80 channel configurations. Specify channel count and connector type (TRS, XLR, or DB25) when ordering. Each unit is custom-calibrated to your interface model.
