Recently, Swiss media company SRG-SSR has equipped three of its production OB Vans (a fourth is coming) with state-of-the-art immersive audio monitoring systems from PSI Audio. Specifically, one OB Van serves each of the SRG-SSR channels: RSI (Italian), RTS (French), and SRF (German). As a result, the company can provide optimized quality for mobile productions such as sports, entertainment, or musical events.

The vehicles, called PaaM-M, contain three PSI Audio A23-M monitors at the front, two A14-M surrounds, four A14-M units on the ceiling, and a Sub A125-M for LFE. All of these were immaculately integrated by Broadcast Solutions in an acoustics environment designed by Jochen Veith.

Moreover, the company’s engineers, who selected PSI Audio speakers through sophisticated blind tests, now report that they can sometimes achieve better results in the PaaM-M OB Van than in traditional studios. Since the PaaM-M vans were put into operation, RTS has equipped another OB Van with a similar PSI Audio system, and additional expansions to the fleet are planned.

Speakers used:

– LCR: A23-M

– Surrounds and heights: A14-M

– LFE: Sub A125-M

Recently, the University of Surrey has installed a large immersive audio setup featuring 23 PSI Audio speakers in a new multi-purpose listening room. Specifically, the system includes 17 A23-M monitors, two A25-M units, and four Sub A225-M, forming an elaborate setup that can be adjusted to accommodate a variety of formats – ranging from ring of eight, quad, and stereo to 5.x and 7.x, as well as object-based formats like Dolby Atmos.

Thanks to this configuration, the university achieves excellence in media creation while benefiting from the pinnacle of Swiss precision sound – truly a match made in Surrey.

Speakers used:

– LCR: A25-M & A23-M

– Surrounds and heights: A23-M

– LFE: 4x A225-M

Renowned Zurich University of the Arts in Switzerland (ZHdK for Zürcher Hochschule der Künste) also relies on precision speakers by PSI Audio. Specifically, multiple editing suites and a stereo control room are equipped with monitors from the manufacturer, and now a freshly installed Dolby Atmos system also delivers Swiss precision.

In addition, with the introduction of the new master’s degree course in sound design, ZHdK built a smaller Dolby Atmos control room to complement the large mixing stage. This new facility features a 7.1.4 speaker setup by PSI Audio, ensuring top-quality immersive sound for students and professionals alike.

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.
