Swiss media company SRG-SSR has equipped three (the fourth one is coming) of its production OB Vans with state-of-the-art immersive audio monitoring systems from PSI Audio. With one of the OB Van for each of the SRG-SSR channels, RSI (Italian), RTS (French) and SRF (German), the company provides optimized quality for mobile productions like sports, entertainment or musical events. The vehicles, called PaaM-M, contain three PSI Audio A23-M for the front, two A14-M surrounds, four A14-M on the ceiling and a Sub A125-M for LFE, all immaculately integrated by Broadcast Solutions in an acoustics environment designed by Jochen Veith. The company’s engineers, who chose PSI Audio speakers in sophisticated blind tests, now claim they can sometimes achieve better results in the PaaM-M OB Van than in traditional studios. Since the PaaM-M OB Van were put into operation, RTS has equipped another OB van with a similar PSI Audio system, and more additions to the fleet are planned.

Speakers used:

– LCR: A23-M

– Surrounds and heights: A14-M

– LFE: Sub A125-M

The University of Surrey has installed a large immersive audio setup of 23 PSI Audio speakers in a new multi-purpose listening room. 17 A23-M, two A25-M and four Sub A225-M constitute an elaborate system that can be adjusted to accommodate a number of different formats, from ring of eight, quad and stereo to 5.x and 7.x to object-based formats like Dolby Atmos. The university for excellence in media creation and the pinnacle of Swiss precision sound – a match made in Surrey.

Speakers used:

– LCR: A25-M & A23-M

– Surrounds and heights: A23-M

Renowned Zurich University of the Arts in Switzerland (ZHdK for Zürcher Hochschule der Künste) relies on precision speakers by PSI Audio. Multiple editing suites and a stereo control room are equipped with monitors from the manufacture, and now a freshly installed Dolby Atmos system also boasts Swiss precision. With the introduction of the new master’s degree course in sound design, the ZHdK built a smaller Dolby Atmos control room to complement the large mixing stage. The new facilities run a 7.1.4 speaker setup by PSI Audio for top-quality immersive sound.

Speakers used:

– LCR: A17-M

– Surrounds and heights: A17-M

– LFE: Sub A225-M

Mixed and Matched Speakers for Dolby Atmos

MD Productions relies on loudspeakers from PSI Audio for complex Dolby Atmos productions. With a system comprised of A23-M, A21-M and A14-M, the Karlsruhe-based company is working on ways and means to increase the immersive quality of documentaries in particular. The innovative approach aims to acoustically integrate the audience into the presented setting, creating a stronger emotional connection to the content. The Dolby certified studio is also exploring completely new, unusual possibilities for immersive audio, for example in medicine and therapy. The precise loudspeakers from the Swiss manufacture provide the required unadulterated sound fidelity in a 7.1.4 setup.

Speakers used:

– LCR: A23-M

– Surrounds: A21-M

– Heights: A14-M

– LFE: Sub A125-M

Is PSI Audio suitable for Dolby Atmos?

Yes. In fact, many Atmos studios choose PSI Audio specifically for its phase accuracy and unit matching.

Do I need DSP correction in an immersive room?

No. PSI Audio achieves precision through analog engineering, not digital compensation.

Which speakers should I choose for height channels?

A14-M or A17-M (or even bigger) depending on room size and SPL requirements.

Can PSI Audio monitors be mixed with other brands?

Not recommended in immersive setups – it breaks coherence and imaging.

How many subwoofers do I need?

For a 7.1.4 room, one A225-M is often enough.

For 9.1.6 or larger rooms, two are recommended.
