hm-115 High Definition Stage Monitor System



As the latest evolution in a family of world-renowned stage monitors from VUE’s Design Chief Michael Adams, VUE’s hm-Class formula has been perfected over the course of many decades. In fact, the hm-115’s footprint and transducer orientation is the direct descendent of classic monitors that have shared the stage with acts such as Toby Keith, Frank Santana, Boz Scaggs, Rage Against the Machine, Def Leppard, Brian Setzer, Gary Allan, Lenny Kravitz, Elvis Costello, and Lucinda Williams to just name a few.

The new hm-115 updates this legendary formula by taking full advantage of VUE’s most advanced technologies and the same “No Compromises” design philosophy behind the company’s flagship h-Class systems. From its precision, beryllium-infused HF transducers, to the companion rack-mount V4 VUEDrive Systems Engine with next-generation DSP capabilities, the hm-115 is a fully integrated, electro-acoustic monitoring system that delivers unparalleled output and fidelity for the most demanding fold-back applications.

Rugged and Purposeful Enclosure Design

The precision-engineered transducers are housed in a rugged and extremely low-profile enclosure that ensures clear sight lines from the audience (or camera) to performers while providing a large sweet spot for talent–whether directly over the monitor or downstage.

Durability is ensured thanks to a rugged, 12-step DuraCoat LX finish and a heavily braced, powder coated grill capable of surviving the most dramatic lean-ins, stomps, or occasional “axe” bludgeoning.

Road Tested and Stage Ready

The hm monitors are designed as our consummate high definition stage monitor systems. They benefit from Design Chief Michael Adams’ more than 30 years of working with world-class artists in demanding live and broadcast applications. Leveraging his extensive real-world experience, Michael has addressed everything from coverage and directivity to system and floor geometry. The goal? To ensure that the VUE hm-112 and hm-212 deliver unsurpassed consistency, whether directly overhead (handheld), or upstage.

But all that only scratches the surface. Thoughtful cabinet design ensures that the hm monitors offer minimal visual intrusion between audience and performer.  Their uniquely low profile ensures that coveted sight lines are preserved for set designers and video producers alike, while also reducing required truck space when it’s time to pack up and go. The hm monitors offer exceptionally clean and wide dynamic range – allowing monitor engineers to place solos or vocals in the front of the mix, exactly where they belong.

Finally, the hm-112  benefits from sophisticated DSP via the companion V4 VUEDrive Systems Engine. This ensures minimal reflections and optimal tuning to avoid the typical hurdles that plague less sophisticated monitor systems.  Thanks to Michael Adams’ real-world perspective, hm monitors arrive from the factory fully ready to rock, with minimal tweaking.

Cutting Edge Transducers

It all begins at the core, where the hm-115 monitors combine a precision-engineered 15-inch LF transducers with a horn-loaded compression driver that features VUE’s revolutionary Truextent® beryllium diaphragm. Thanks to beryllium’s extremely high stiffness-to-mass ratio, this unique compression driver delivers dramatically more HF definition, intelligibility and output than more conventional aluminum or titanium-based designs. The driver features a massive voice coil and magnet assemblies designed to minimize power compression while ensuring consistent fidelity and feedback stability right up to maximum output.

Systems Engine

Powerful Amplification and DSP

v4-dThe hm monitors are a fully integrated electro-acoustic system that includes the companion V4 Systems Engine, a 2-in/4-out rack-mount processor/amplifier that provides two mixes and four channels of amplification for more than enough “oomph” for two hm-212 systems, or up to four hm-112 systems.

When bundled with the hm monitors, the V4 Systems Engine’s highly sophisticated digital signal processor is optimized specifically for on-stage environments, the unique transducers and cabinet geometry of each hm model. As a result, users can quickly assemble a perfect artist reference system that delivers absolute fidelity across the stage with zero feedback.

Networking Capabilities are Standard

network-dig-02The V4 Systems Engine provides networking and remote management capabilities as standard. There’s no need for additional cards or retrofitting.  Right out of the box, users can easily assemble expanded networks and use the intuitive SystemVUE software (Mac and Windows) for remote monitoring and control of each element or device on that network. And, since VUE’s network technology relies on standard IP protocols, setup is a breeze.
