CHAPTER 7
When fitted with the optional MRF-600 rigging frame, the
600-HP may be flown alone or with MICA curvilinear array
loudspeakers. It may also be ground-stacked in vertical
and horizontal arrays using this version or the versions with
handles or plain side panels.
Using subwoofers to supplement the low-frequency head-
room of a full-range or mid-high sound reinforcement sys-
tem requires an understanding of how subwoofers respond
when grouped together, how they interact with nearby walls
and floors, and how their location in a system affects their
use in relation to other loudspeakers.
FLYING THE 600-HP SUBWOOFER
The 600-HP subwoofer optionally features Meyer Sound’s
QuickFly rigging system with rugged, reliable and simple
components. QuickFly facilitates deploying the loudspeak-
ers in a variety of applications. The 600-HP is designed to
be rigged using professional components, and its custom
front and rear GuideALinks™ rigidly couple the individual
subwoofers to each other or along with MICA array loud-
speakers for flying, stacking, or transporting in stacks while
still in various splayed positions.
CAUTION:
All Meyer Sound products must
be used in accordance with local, state, fed-
eral and industry regulations. It is the owner’s and/or
user’s responsibility to evaluate the reliability of any
rigging method for their application. Rigging should
be carried out only by experienced professionals.
CAUTION:
Always use properly rated rigging
hardware.
CAUTION:
It is important to inspect rigging
hardware regularly and replace worn or dam-
aged components immediately.
GUIDEALINK RIGGING FRAME
600-HP subwoofers equipped with the optional MRF-600
rigging frame can be linked directly to the MG-MICA grid
and to MICA loudspeakers to form flown and ground-
stacked arrays.
The 600-HP’s captive QuickFly rigging hardware — like
MICA’s — features rigid GuideALinks contained within
recessed guides in the bottom front and rear cor-
ners of the enclosure. A slot and convenient pinned
knob allow each link to be moved and pinned for ar-
raying and storage. In normal use, the front links
are used as the pivot point, and the splay be-
tween enclosures is introduced with the rear links.

Figure 7.1. Front and rear GuideALinks
The rear links provide seven positions, marked -3, 0, 3, 6, 9,
12, and 15. The resulting angle these link positions repre-
sent depends on whether the 600-HP is linked to another
600-HP or to a MICA loudspeaker.

CAUTION:
As part of the regular inspection
and maintenance procedure for 600-HP
loudspeakers, check each of the captive GuideALink
pins to ensure that they are tight by turning them
counterclockwise by hand. If a pin turns, it must
be reset into the link using Loctite
®
290, and be
allowed to cure for 48 hours and retested before the
loudspeaker is flown.
