PLASA’s Prime Launches Now in Production- 29 October 2009 at 09:28
The loudspeakers we launched at PLASA09 are now in production. These include the Stasys Prime wide-band arrayable point-source system, which offers ground-breaking efficiency; the Stasys 5 Mk2 low-frequency system that uses a pressure plate to enhance its transient response, plus the Arcline 12 medium-format line-array enclosure. We also launched two further models in the Infinite X amplifier range.
Stasys Prime – power saving efficiency A wide-band loudspeaker design for large-scale touring, arena and stadium sound, our new Stasys Prime uses 2 x 15” LF drivers and a 1 x 1.5” neodymium HF driver to deliver a continuous output of up to 142dB. This raises point-source arrayable enclosures to a new level of performance, with ground-breaking efficiency, and an extended low-end down to 90Hz negating the need for separate upper-bass enclosures. Achieving lossless summation between adjacent enclosures, the design offers a seamless transition within an array, greatly improving intelligibility and phase coherence, as well as efficiency, as adjacent outputs are free from destructive interference. Stasys Prime’s super-high efficiency and 2-way active operation makes it an environmentally-conscious system, needing fewer amplifiers, with lower output power, to deliver a given result, while easing handling and transport.
Stasys 5 Mk2 – passive plate serves faster transients The Stasys 5 Mk2 low-frequency 1 x 18” enclosure is designed for demanding live performance applications – on the largest tours or in the biggest arenas. This innovative design harnesses some of the energy that would normally be dissipated in its rear chamber, by firing the transducer onto a passive aluminium pressure plate – the plate’s restoring force is reflected back onto the transducer to provide a substantial increase in transient response and efficiency, and a continuous output of 135dB. As with all our premium enclosures, the use of resonance mapping has resulted in an extremely ridged structure, with very low colouration. The Stasys 5 Mk2 also uses 'coolwave' technology to reduce thermal compression to a minimum and ensure consistently high output levels – used in combination with our recently-developed 5” double-coil neodymium drive unit to give the enclosure an output-to-weight ratio near the theoretical maximum, and making it one of the lightest enclosures of its type available.
Arcline 12 – medium-format line array with extended low-end Our new medium-format Arcline 12 line array enclosure solves the challenge of generating a coherent cylindrical wavefront – from a typical hang – that exhibits the same decay-per-distance in lower octaves as the mid and HF frequencies. To achieve this, the Arcline 12 incorporates a high-efficiency horn-loaded low-mid section, which delivers the necessary low-frequency projection down to 90Hz. Using the same principle as the Arcline 6, the new Arcline 12 has its physical components positioned on an arc to form a common virtual feed-point, with this approach, in conjunction with the design’s 120-degree horizontal dispersion, enabling the system’s wide and uniform coverage pattern, free from phase and response anomalies.
Infinite X – UK-made switch-mode power Manufactured in the UK, using our dedicated production facility, the Infinite X range includes two- and four-channel amplifiers, featuring high-efficiency, high-current switch-mode power supplies. Launched at PLASA were the Infinite X7 and X8 two-channel designs, delivering 2 x 2000W and 2 x 2600W into 4 Ohms respectively. All models deliver increased power output into a 2 Ohm load.
