Renowned Swedish producer and mix engineer Thomas “Plec” Johansson has helped shape the sound of countless records across genres. Known for his precision and artistic touch, Plec’s studio, The Panic Room, is trusted by artists worldwide for mastering. At the heart of his setup are two standout names: Weiss Engineering and PMC Speakers.
Weiss: Trusted Tools with Character and Control
Plec has been a long-time advocate of Weiss Engineering’s mastering tools. His setup includes an EQ1 and not just one, but three DS1 units. For him, these aren't just processors, they’re integral to nearly every mastering session he does.
In the interview, Plec explains that both the hardware and software versions of the DS1 play important roles in his workflow. He uses the Softube DS1 plugin, which he acknowledges as a faithful 1:1 code port of the original. Still, after extensive A/B comparisons, including blind tests over the course of a year, he feels there’s a subtle sonic difference. The hardware DS1 has a slightly grittier texture, which he describes as having a bit of “mojo.” The plugin, by contrast, sounds cleaner. He emphasizes that both are incredibly effective and equally valuable depending on the context.
Plec is especially impressed by the flexibility of the DS1. Its detailed control over attack and release times allows him to shape the processor’s response to suit the music. While he has developed a few go-to presets tailored to specific tasks, he admits the unit still reveals new depths the more he uses it. “It’s definitely a tool you need to familiarize yourself with,” he says, “and I still don’t feel like I’m done exploring it.”
This blend of high precision, musical response, and long-term usability is what makes Weiss tools a cornerstone of Plec’s mastering chain.
PMC Monitors: Clarity That Translates
When it comes to monitoring, Plec turns to PMC MB3S XBD-A speakers. He values their ability to deliver an accurate picture of what’s happening in the music. With PMCs, what he hears in the studio closely matches what listeners hear outside of it. This reliability makes his mixing and mastering decisions more efficient and consistent.
The clarity and phase alignment of PMC monitors help Plec identify tonal imbalances or stereo imaging issues with confidence. They allow him to work faster, with fewer revisions, because he knows his results will translate.
A Workflow Built on Confidence
What unites Weiss and PMC in Plec’s setup is trust. These tools give him the precision needed for critical listening, while maintaining the musical integrity of each track. For engineers looking to upgrade their studio, Plec’s approach shows the value of tools that reveal the truth without sacrificing feel.
Investing in high-performance gear like Weiss processors and PMC monitors can help bring out the best in every project.
