Starting with a “no-compromises” design philosophy, VUE’s h-Class engineering team re-examined every element of the loudspeaker equation, and then applied our most advanced technologies to deliver measurable improvements in clarity, frequency response and SPL. From precision engineered transducers with cutting-edge diaphragm materials and suspension components, to highly-sophisticated active electronics and DSP, every element of VUE’s h-Class was optimized to deliver unparalleled sonic performance.
h-Class systems were also designed to be highly versatile. The h-12 is available in both wide and narrow coverage versions, while built-in pole mounts and optional rigging hardware allow easy deployment as a main system, or in a variety of support configurations.
Cutting-Edge Transducer Design
The h-12 self powered two-way system employs a VUE-designed compression driver that features a revolutionary Truextent® beryllium diaphragm at its core. Beryllium outperforms both aluminum and titanium thanks to an extremely high stiffness-to-mass ratio, which dramatically reduces mechanical deformation and shifts breakup nodes up in frequency well above the audible range. The net result is a more defined high frequencies at much higher SPLs than more conventional materials. High frequency performance is further enhanced thanks to a complex five-slit phase plug and a powerful, lightweight neodymium magnetic circuit.
The unique compression driver is mated to an equally capable low frequency transducer that is also designed and manufactured by VUE specifically for the h-12. This precision-engineered 12-inch transducer utilizes a large, 4-inch (100 mm) voice coil to dramatically increase power handling while minimizing power compression losses. An impregnated linen surround, curvilinear cone optimized for mechanical stability is supported by a massive high coercivity ferrite magnet circuit. The LF driver’s over built consecution provides exceptional durability to ensure years of reliable service under the most severe conditions.
The h-12 is fitted with a 2-channel power amplifier module that supplies 830W long-term, sine wave (2000W peak) to the LF transducer, and 275W long-term, sine wave (400W peak) to the beryllium compression driver.
The module’s Class D circuitry allows for massive output and headroom in an extremely compact form factor, while producing significantly less heat than more conventional designs. The amplifier is mounted to a large aluminum heat sink with machined “VUE” logo. The combination of Class D amplification and ample heat dispersion eliminates the need for noisy cooling fans.
A lightweight, fully protected switch mode power supply with auto voltage detection provides hassle-free worldwide operation with universal mains operation for 120 V and 230 V. Self-protection circuitry includes input limiter, short circuit protection, DC protection of output, under and over voltage protection, intelligent mains fuse protection, power stage overload protection, and temperature protection of both transformers and heat-sinks.
Sophisticated DSP and onboard networking capabilities come courtesy of a 64-bit, 96 kHz sample rate, mixed-mode processor that delivers 120 dB of dynamic range with less than 600 microseconds latency.
Finally, since full networking capabilities were conceived as part of the amplifier module’s initial design specification, the h-12 module provides impressive amounts of detailed, real-time information, as well as access to key operating parameters when connected to the SystemVUE network. Accessible functions and monitoring options include: protect status, mute, heatsink temperature, clip (for each amp channel), output voltage (for each channel), output current (for each channel), and SMPS limit (power supply limit).
Quality Down to the Finest Details
Even the smallest details of the h-Class systems are made to a raise the standard of what you can expect from a professional loudspeakers system. The grills and handle bezels are coated with a two part finish that lays a transparent candy-apple red coating on top of a base coat of black to give the systems a deep texture while remaining unobtrusive.
All h-Class enclosures are manufactured to the strictest ISO standards, using multi-ply, cross-grain laminated Baltic birch with extensive interior bracing for resonant free output. Full-range models include integrated hanging points for use with optional flying hardware. A rugged, polyurethane finish ensures years of on-the-road service.
Finally, every h-Class model ships with networking capabilities builtin right out of the box. And since VUE’s network technology relies on standard IP protocols, set-up is a breeze. Once assembled, supplied SystemVUE software provides control and monitoring capabilities through a highly intuitive and powerful user interface.
