Any experience with the HOLOPLOT X1 Matrix Array?

(1/4) > >>

Art Welter:
EAW’s adaptive array technology in the form of ANYA , ANNA and the AC6, and Martin’s MLA have allowed DSP controlled pattern variations in the vertical realm, while having a horizontal pattern determined by the cabinet design.

HOLOPLOT has taken beam-forming from one dimension to two, both horizontal and vertical, having gone from prototypes in early 2011 to production of the X1 Matrix Array, using M96 and/or M80-S modules.

https://holoplot.com/systems/

Each of the drivers (96 or 80) in the cabinets use individual amplification and DSP (8700+ filters computed in real time) to enable “3D Audio-Beamforming” and “Wave Field Synthesis”.
3D Audio-Beamforming allows for shaping and steering of beams in two dimensions to create sound fields to cover areas of any shape and size, with up to 12 independent beams per Audio Module, and 24 parametric EQ bands per beam.

Wave Field Synthesis enables sound localization with distance and directional cues for perception of audio objects in virtual soundscapes.

Any of you heard the X1 Matrix Array at InfoComm 2022, or at any of their other installations or demos?

A colleague did a multi-night stand at NY's Beacon Theater with the installation there. The steering did a fine job of keeping energy off the walls, but there was WAY too much LF kicked back onstage vs. the K2 rig he's been using (and in the same venue with).

Requiring a dedicated 20 [email protected] for each cabinet, and 9 2-ton hoists to lift rig, it ain't exactly green. (Custom Tait flying structure).

Processing is 48khz.

For traditional concert format the "3D" panning seems of limited usefulness...currently.

Mike Caldwell:
Lots of DSP power going on for sure!!

The only steerable systems I have encountered has been a couple of the larger Tannoy and Intellavox column speakers. They did what they were said to do but the software interface was horrendous and needing to jump between two programs to build the steering files and then apply it to the speakers.
Granted that was a few years ago so maybe it's been updated at this point.
More so with the Intellavox system but any tweak to the steering noticeably changed the voicing.

Never been around any of the big boy EAW or Martin stuff.

Jim,
The Beacon installation appears to be two cabinets wide in relation to the stage.
The HOLOPLOT Matrix Array size vs beamwidth chart indicates a 2x2 at 150 degrees at 100 Hz, not much control down low.

Did the K2 rig use a cardioid sub configuration?

Yes indeed. Feedback from musicians and MON was that the Holoplot onstage was really old-school nasty, like S4/850 LF swamp.
