The hs-221 utilizes VUE’s revolutionary Active Compliance Management (ACM) technology to reset the size-to-performance benchmark for subwoofer systems. The combination of ACM technology and the hs-221’s highly-sophisticated on-board electronics result in massive amounts of pure, clean low-frequency energy from a dual 21-inch configuration that embodies a significantly smaller enclosure than other dual 21-inch designs.

Features

  • ACM™ Active Compliance Management: Patent-pending hybrid design combines both band-pass and vented alignments into a single, compact footprint for more output and definition
  • Infrasonic Bass: Utilizing the ELF(Extended Low Frequency) mode the hs-221 provides flat response down to 27 Hz and useable output to below 20 Hz without sacrificing transient or musical definition
  • Tons of horsepower: Dual monaural amplifier modules supply 1000W pure sine wave power (2500W peak power) to each woofer
  • Purpose-designed transducers: Dual 21-inch, long excursion with 5-inch (125mm) voice coils
  • SystemVUE software: Mac, Windows, and iOS compatible software provides access to monitoring and control functions such as fully parametric EQ, speaker protection, input/output levels, volume, mute, delay and input sources
  • Simplifies Setup of Directional Arrays: Software control and on-board DSP support virtually all directional array configurations without the need for external processing (factory presets included for basic CSA arrays)
  • Standard IP for easy networking onboard: Simply plug-in, and the system automatically connects to virtually any kind of IP configuration
  • Built for the road: Premium birch plywood enclosure with extensive internal bracing and a highly durable Dura Coat finish

Applications

  • Broadcast TV
  • Symphonic fold-back
  • Theatrical sound reinforcement
  • Portable and installed audiovisual systems
  • Themed entertainment venues
  • Places of worship

Donwload Technical sheet

 

The combination of ACM, precision-engineered transducers, and sophisticated electronics, allow the hs-221 to deliver very high output while providing flat response down to 27 Hz (in ELF mode). The hs-221’s enclosure has a more compact footprint than most dual 21-inch systems and even some dual 18- inch designs.

VUE’s patent-pending ACM technology combines both band-pass and vented alignments into a single enclosure. The hs-221 places two high performance, 21-inch transducers into this configuration, with both woofers sharing a common vented chamber. One woofer’s frontal radiation is direct, while the second woofer’s frontal radiation drives the band-pass chamber.

To make the two ACM subsections combine acoustically we use sophisticated DSP to precisely align the phase arrivals of the front facing woofer, the common chamber vent, and output of the band-pass chamber vent.  The powerful amplifier sends 1,000W of pure sine wave power (5,000W “burst” ) with a unique optimal signal to each woofer. The combination of 5,000 watts of burst power produces 143 dB SPL peak output in free field (149 dB SPL half space – ground plane environment).

If the hs-221 DSP detects a viable digital signal (via the EBU AES digital input and passes through the XLR connectors), it will use that signal and mute the analog input. If the digital signal is lost, the DSP will automatically return to the analog input to avoid interruptions. The default is AES channel 1, however the SystemVUE software allows users to remotely access each hs-221 on the network and select AES digital channel 2 or a mono sum of channels 1 and 2. SystemVUE can also select the input Dante from the network connection.

The hs-221s are equipped with two RJ-45 Ethernet connectors (with an internal switch for cascading network connections). Hs-221 supports remote control and monitoring via ethernet via SystemVUE software. The Ethernet connection can also be used for Dante Network Audio Stream input (selectable through the SystemVUE software).

SystemVUE™

Like all h-Class systems, the hs-221 comes with built-in networking capabilities. There is no need for additional cards or retrofitting. VUE uses standard IP protocols to simplify the networking process. Just plug it in and the hs-221 will automatically connect to any type of IP configuration. Users can then access and monitor parameters at the network and device level via our SystemVUE ™ software. The Ethernet connection also allows the use of Dante® for audio transport.
