It’s been a while since we last told you about our endeavors, so today we decided to make amends. That’s to say we will share some information about one of our most complex projects that we started in 2015 and completed in the summer of 2016, namely the sound system for the Aqua Angar Spa Centre in Cehu Silvaniei.
Located at 114 km from Cluj-Napoca, the Aqua Angar centre is one of the most modern of its kind in Transylvania. Equipped with a massage room, pool, bar, fitness room, squash court, ballroom, sauna, outdoor beach and many others, the Spa required an integrated audio system that allowed volume control in each area.
A universally accepted solution for this system was a conventional 100 V, but that meant compromising the sound quality, as transformers needed to be integrated in the system to reduce sound volume.
However, since the owner wanted more sound sources in each of the 19 areas, things turned out a little more complicated than it seemed at first glance. But we knew it was possible. It required a network controller which could select the source area as well as the volume. This controller gave us the advantage of having all the sound equipment in a central technical area.
Still, to follow through, we had to deal with two major system components, the amplifiers and the command and control, along with the corresponding software. Moreover, we had to find the method to combine them. To be honest, the amplifier module was familiar to us because we had completely developed it in house two years before, so we focused on designing and integrating the control and command module.
After a few weeks of careful planning we came up with a working prototype. However, it took us nearly a year to complete the function development and improvement. We performed tests continuously for 8 months before agreeing on the perfect solution. After this success, we determined the number and type of speakers for each area and developed the central technical area.
In the final version of the project we used 6 amplifiers with 4 channels each, … speakers, 2.5 kilometers of cable for voice and 800 meters of cable for data. The amplifiers are fitted in a standard 2U chassis developed by us and the controllers have a futuristic design, featuring a combination of glass and brass.
We installed P1.3 (http://bit.ly/1JvN5fN) P2.3L (http://bit.ly/1IV1O4V) P4.3L (Http://bit.ly/1VqHv3n) P4.3S (http://bit.ly/1K9svEG) and P4.3F (http://bit.ly/1TfRKGN) speakers, as well as a Hifi Estelio audio system (http://bit.ly/1KpjA1J).
In the end, all 19 distinct areas of the Angar Aqua Spa centre, including different Acoustic Density speakers and amplifiers with zone controllers are functional and look absolutely amazing. Basically, you can listen to the music you want from the four sources and select the volume. We did it and we are proud!
