CHAPTER 7
The front links may be set in two different positions:
■
0°: This is the standard position (left figure) and it is
used to achieve a 0-degree angle between adjacent
600-HP enclosures.
■
+3°: The main purpose for this extended position (right
figure) is to curve a 600-HP stand-alone array that is
flown next to a MICA array, both for appearance and to
keep the subwoofer array from blocking the horizontal
high-frequency coverage from the MICA enclosures
lower in the array.

RIGGING CONFIGURATIONS AND TILT ANGLES
The resulting angle from the positioning of the front and
rear links depends on whether they are being used to link to
other 600-HP subwoofers or to MICA array loudspeakers.
600-HP to 600-HP
Flown
When 600-HPs are flown, the GuideALinks allow a vari-
ety of combinations. However, the most common is at 0
degrees. In addition, when flown it is possible to achieve to
a 3-degree downtilt to curve a 600-HP stand-alone array
that is flown next to a MICA array, both for appearance and
to keep the subwoofer array from blocking the horizontal
high-frequency coverage from the MICA enclosures lower in
the array.

NOTE:
Not all mechanically possible com-
binations between two 600-HP are useful
— for example, concave angles between two subs.
These combinations are possible because the 600-
HP rigging was designed to also allow a wide num-
ber of combinations between 600-HP when flown or
ground-stacked with MICA loudspeakers.
Ground-stacked
When 600-HPs are ground-stacked, the GuideALinks allow
a variety of combinations. However, the most common is at
0 degrees. In addition, it is possible when ground-stacked
to achieve to a 3-degree uptilt to curve a 600-HP stand-
alone array for purposes of appearance.

600-HP to MICA
Flown
MICA and 600-HP loudspeakers can be combined within
the same array to supplement and extend low-frequency
headroom in the system. The rigging on both models is
completely compatible. When flown, the 600-HP sub-
woofers are typically positioned at the top, and linked to
the MICA with an uptilt or downtilt as needed to meet the
requirements of the installation.
