Customer reviews – What Engineers Say
Resolution and Stereo Image
“The first thing I noticed was how the mix feels glued together. It’s reminiscent of working with tape — those harsh transients become smoother, resulting in a warmer, more musical mix. There’s a certain velvety quality to the sound. I also have the impression that the Haufe-Pikatron transformers generate some ssl-ish subtle harmonic content, creating an excellent sense of even frequency distribution across the entire spectrum. The mix isn’t dull or overly hyped — it’s simply a great and precise like on api consoles, truly analog sound. The stereo image is unbelievable — a huge step up from MiB (Mix-in-a-Box) workflows. Bass frequencies are perfectly balanced, from the lower mids all the way down to the sub range.” — Dejan Radievic – Read more on Gearspace (formerly Gearslutz)
Paul’s Summing Box – The Real Thing!
“My summing box handles 32 inputs (16×2), has two stereo outputs, and uses Lawo transformers — and what can I say: it does exactly what I was looking for. Every little thing, every detail in the mix — instruments, vocals, reverb, everything — now sits exactly where I want it to be. It honestly feels like there was a curtain between my ears and my Genelec monitors that has finally been lifted. I’m very happy with this setup and want to thank Paul for all his support and the truly fine craftsmanship he delivered for me and my studio. Thanks!” — Customer Review from Gearspace (formerly Gearslutz) Read more on Gearspace
The Lawo DV975 — German Broadcast Console Heritage
Lawo was founded in the early 1970s by Peter Lawo in Rastatt, Germany. Known for its precision engineering and broadcast innovations, Lawo became a key name in European professional audio. Before transitioning to digital systems, the company produced a series of modular analog consoles and amplifier cards, such as the DV97x and DV975 — now sought after by engineers and boutique builders for their sound quality and robust design. Today, Lawo remains widely recognised as a leading console manufacturer, delivering high-end mixing systems for broadcast, live productions and studios globally. See more about Lawo

Frequently Asked Questions
What makes the Lawo DV975 summing mixer special?
The DV975 is a handbuilt analog summing mixer using genuine Haufe/Pikatron transformers and fully discrete amplifier topology. It delivers SSL-style punch, API-like clarity, and the unmistakable warmth of German studio heritage. Every mix benefits from rich harmonic depth, precise stereo imaging, and natural analog glue.
How many channels can the mixer handle?
The Lawo DV975 can be custom-configured from 4 up to 64 channels, depending on your studio setup and workflow needs.
What kind of signal path does it use?
Fully balanced, dual-stereo signal path with a fully discrete amplifier placed between the input and output transformers
Can I order a custom channel count?
Yes — units are available in 8–64 channel configurations. Specify your desired channel count and connector type (TRS, XLR, or DB25) when ordering. Each unit is custom-calibrated to your interface model for optimal performance.
How does the Lawo DV975 affect the mix?
Engineers report smoother transients, velvety tonal quality, and a better-defined stereo image. Bass and low mids are balanced across the spectrum, giving a natural analog feel while maintaining mix clarity and precision.
Is the harmonic character subtle or pronounced?
The Haufe/Pikatron audio transformers provide rich, musical harmonics without overpowering the mix. They enhance tonal balance and stereo image without artificial hype—think subtle SSL-like harmonic enrichment combined with API-style clarity.
What’s the price range?
Depending on channel count and configuration, prices range from €690 to €2,200.
Who uses the Lawo DV975?
Professional mix engineers, boutique studios, and experienced home producers who want real analog depth and precise summing often rely on the DV975. Customers praise its ability to make every instrument, vocal, and effect sit naturally in the mix.
Does the Lawo require external gain recovery?
No. The DV975 includes an integrated discrete gain stage, so external makeup gain is unnecessary. Using high-quality preamps can, however, enhance tonal character further.
