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.

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.

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.
