Recently, we visited South Korea at Seoul’s Sejong Center for the Performing Arts, where we were fine-tuning the new SIAP Acoustic Enhancement System in the esteemed Grand Theater. Sejong Center opted to upgrade to our latest technology. The result was very pleasing.

A very nice multifunctional venue in Hapert, The Netherlands, boasts a splendid stage and a wide range of programming. The new SIAP system will be utilized for many applications. Several times a week, the local brass band will rehearse, and concerts will be held regularly, during which the SIAP system will enhance the acoustics.

The last two days we were at Theater de Purmaryn in Purmerend (north of Amsterdam) to upgrade the SIAP system to the latest SIAP Mark V system. Very nice to be there again, such a cosy theater with its 550 seats.
Theatre De Purmaryn was the first SIAP customer, back in 1989(!) At the time when the Theatre was being built, they flew with us to the UK where the first demonstration system was installed in the Beck Theatre Theatre in Hayes, Middlesex (London Area).

After this successful demonstration this theatre immediately wanted to have this system. Already 33 years ago! Such a nice history and a special venue for us.
Thanks to @Bert Huiberts and @Leon van Wijk for their enthusiasm for the system after commissioning. The hall is now again equipped with the latest variable electronic acoustics and technological highlights.

It was a special and great experience, the last May week in Mumbai, India. After our initial contact with the new prestigious Dhirubai Ambani International Convention and Exhibition Centre (DAICEC), now called Jio World Centre (1 billion $ construction cost!), in Mumbai (2018) we finally went there to tune our SIAP system. This week was special.

This project includes a convention and exhibition centre, cultural square, apartments, a luxury shopping mall, an office building, and a very luxurious theatre / auditorium, based on the design of the Dolby theatre in Hollywood. The hall has a capacity of 2,000 seats and is used for a wide range of performances, both western/international and Indian: live performances (theatre), amplified and unamplified concerts, cinema, and congress purposes….

SIAP installs new MkV system in the renovated MAPO Art Center, Seoul South-Korea (LinkedIn article). The partnership with ANK and Blackstone Records appeared to make a very successful team with us from SIAP. You guys did an impressive and excellent job! With immersive sound, from Theater Ambiance (in conjunction with the Front-of-House reinforcement system), to variable acoustics (from jazz piano club to opera house and from concert hall acoustics even upwards to a real cathedral) and with movie surround (Dolby 5.1 / 7.1 / 9.1 support and Atmos compatibility) this MAPO Art Center has become ‘soundwise’ multipurpose.

The system is Dante Audio based, which therefore becomes an “open” system as well. Easily connect with other equipment or (effect) processors to get even more versatile. The sound is amazingly natural: we have used Focal speakers with an excellent smooth frequency response and wide dispersion. Together with the natural acoustic of the theatre itself, the SIAP system gives a very compelling, warm, and spacious sound. Musicians that have performed on Mapo’s stage, highly appraise the SIAP acoustics. Needless to say, that this theatre will from now on be a SIAP demonstration venue as well.

Seminars will be organized to explain more about the system’s achievements and features. Of course, we are looking forward to our next projects in South-Korea.

DeLaMar, a main Theatre of Amsterdam decided to purchase the newly developed SIAP Mark V processor for their beautifull hall. The Theatre already had the SIAP predecessor Mark IV since the theatre’s inauguration in 2010 but wanted to upgrade to the new processor for all it’s new abilities and features. The system comprises 152 loudspeakers and SIAP is used for unamplified performances (from 0.7 sec. RT to 4.0 sec. RT), as well as for amplified performances (0.7 sec. RT to 1.0 sec. RT) for ambiance and more ‘liveliness’ of the hall and for surround purposes. Therefore, all kinds of amplified and non-amplified shows and concerts benefit from the installation of the Mk V processor in the existing SIAP system. Dante audio networking is used as well to collaborate with other Dante devices, and they love the iPad and the ducking system that can automatically attenuate the active acoustics for announcements or music played through PA during the performance, when desired.  A very versatile system that fully meets the functionalities of today!

SIAP Mark V is here….it talks Dante.

Some Words From Our Clients

“The Concertgebouw Orchestra doesn’t come here just like that. Very good acoustics.”

“Since the renovation this is one of the best theatres for me: great acoustics in the main theatre.” 

“Such a good sound in the Limburg Hall in Theatre Heerlen.”

“I performed at the newly renovated Theatre Heerlen with the Limburg Symphony Orchestra, I was very pleasantly surprised at the quality that has been acquired in the concert hall. Beautiful acoustics and an asset to the region.”

Jaap van Zweden

“The acoustic quality achieved by the SIAP systems enables us to program classical music at the highest level,” says theatre director Bas Schoonderwoerd. “It is now possible to participate in the concert series of touring international orchestras. Since the renovation even the world famous Royal Concertgebouw Orchestra
returns every year: it is the highlight of the season.” The theatre has purchased Stune8, SIAP’s fine-tuning software. The audio engineers are now able to create their own presets and routings.

Integrating a SIAP system


A meeting, visit of the venue, drawings (if exist) and needs will give us enough information to make a proposal and preliminary quotation.


Based on drawings and a visit we’ll make a design that comprises that right amount of equipment for perfect acoustics.


The installation company place and install the microphones, speakers, cables, amplifiers, racks and connect it to the SIAP processor.


The SIAP system will be tuned in three to four consecutive days by specialists of SIAP. All presets will be created and all measurements will be done.


For fine tuning, (subjective adjustment), it is preferable to have one or two extra days with “live” music on stage. We won’t leave until everybody is happy.
