By PSW Staff • April 19, 2018 The Canon of the Netherlands exhibition The Netherlands Open Air Museum gives visitors a unique view of the long history of the country and its people. The “Canon of the Netherlands” is the latest and most ambitious attraction. Built entirely indoors and partially submerged inside a giant egg-shaped dome structure, the Canon of the Netherlands transports visitors from the Stone Age to the present through a series of multi-media vignettes. Local A/V design and integration firm Rapenburg Plaza worked with the Open Air Museum to make the exhibit successful, relying on 44 channels of Ashly Audio fully-networked and DSP-enabled amplification. The Canon of the Netherlands is divided into several sections, and within each section, several displays transport visitors through space and time using innovative audio-visual technologies. An entry zone includes ten uniquely shaped screens, each with its own KEF Ventura 6 loudspeaker powered by its own channel of an Ashly nXp 1504 four-channel 150 watt multi-mode network amplifier with onboard DSP. In addition, four 100-volt Yamaha VXS10ST subwoofers add low-end support where needed and get their power and processing from an Ashly Pema 4250.10 four-channel 250 watt network amplifier with a built-in Protea matrix DSP. The second section again includes ten presentations, each supported by varying numbers of 6-Ohm KEF Ventura 4 loudspeakers. In all, the second section uses 19 channels via five 4-channel Ashly nXp 1504 amplifiers. “Many of the displays required wiring two loudspeakers in parallel,” explains Wilfred de Zoete, sound control & sound engineer at Rapenburg Plaza. “The Ashly nXp Series can handle the 3-Ohm load and very long cable runs that were unavoidable.” Finally, the “Canon” video wall concludes the experience for visitors. Two more Ashly nXp 1504 amplifiers deliver eight discrete channels of amplification to drive as many KEF Ventura 6 loudspeakers. Soundscapes fill the space and elevate the experience. “The Ashly nXp 1504s are all used in different zones but with the same KEF Ventura 4 & 6 loudspeakers,” de Zoete says. “They give us the flexibility of a low impedance setup and 150W per channel – ample power for this application. In installations such as this, there is no need for super high-power amplifiers. That is a benefit of the Ashly product line. In addition to the high-power amplifiers common to other manufacturers, Ashly also offers fully-featured low-power versions. Thus, the client is not paying for extra output that will never be used. The fact that the nXp 1504 is just 1 RU gives the large system a small footprint.” He continues, “The Ashly Network Protocol is easy to use, feature-rich, and integrates perfectly with our show control gear. The most important network functionality is power on/standby, muting, and preset recalls. Although we often use Ashly DSP for intricate setups, we’re using the onboard DSP on the ten Ashly nXp 1504s and one Ashly Pema 4250.10 in a pretty straightforward manner: mostly equalizing for optimum speaker sound and power consumption. Importantly, Ashly’s pricing is competitive and overall quality is solid, which allowed us to design such a comprehensive system while remaining within budget.” Ashly Audio Rapenburg Plaza Tagged with: Amplifiers Ashly Audio AV Installations International Networking Sound Reinforcement Systems · all topics Subscribe to Live Sound International Subscribe to Live Sound International magazine.
