clutter when fitting biscuits and cables on subsequent rows of boxes.
9.
Snap on the next row of flying chains, hooks facing forward, again observing the colour
coding – red for right, blue for left. The length of the flying chain will determine the
vertical angle between the first row and the second row of boxes. You will want the first
row of Flashlights to couple with the long throw boxes on the top row, so place link #27
in the clutch. This will result in a vertical angle of 3.5º between boxes.
10.
Raise the PA about a further metre to
allow the third row of Flashlights to be
wheeled in underneath, having first
loosened the camlocks on the
wheelboards. Snap in a third row of
flying chains, again observing the colour
code. Shorten the chains by placing link
#7 in the clutch, which will result in a
vertical angle of 5
°
between boxes.
11.
Raise the PA another metre or so, and
position downfill boxes face down on the
ground, or face down on a Flashlight
wheel board and roll into place
immediately below each column. There
are two types of downfill, a low-mid
(identified by the EP6 connector) and a
high-mid (identified by the XLR
connector). It is common to ‘chequer-
board’ the downfills so that you end up
with a high-mid, low-mid, high-mid, low-mid, high-mid, low-mid arrangement left to
right across the PA. However there is often an exaggerated coupling of low-mid energy
from the PA and coming from the stage which, combined with the wider dispersion
created at lower mid frequencies, is sometimes undesirable. In this case try using all
high-mid downfills on the bottom row instead to clean up these frequencies close to the
stage.
12.
Shorten each chain by placing link #10 in
the clutch and snap the D-rings into the
flyplates on the downfill boxes. Open the
access door, and take out the tilting strap.
The downfills are angled independently of
the main part of the array by means of
their own tilt straps, which are simply
