How To Fly The Mid-High Unit; Double Projector System - HK Audio PROJECTOR Bedienungsanleitung

PROJECTOR MANUAL
To mount the Tilt Unit, proceed as follows:
1. Set the PROJECTOR system up as described above
2. Remove the recessed socket head screws (A) from the SUB 2's side
panels (two screws per side) as well as from the MID-HIGH UNIT's
panels (1 screw per side)
3. Attach the Tilt Unit's steel brackets (B) to the SUB 2's housing using
two star grip screws (C) each. Make sure that the screws are fastened
tightly and that they hold the steel brackets firmly in place.
4. Insert the star grip screws with bearings (D) through the Tilt Unit's steel
brackets into the threads on the mid-high unit and fasten them tightly.
5. Now tilt the back of the mid-high unit upwards by applying pressure
to the back of the housing. Allow the Tilt Unit to engage at the
desired angle.

2.3 Flying the Mid-High Units
The PROJECTOR MID-HIGH UNITS are equipped with three eight-
position Aeroquip flight rails that allow the cabinets to be flown
(i.e. allow the cabs to be hung from a cross beam or flight rig). These rails
are designed to be used with steel cables that are available as an optional
accessory. The rails on the left and right side of the housing serve to
actually "fly," i.e. suspend the cabinet. The rear rail, in turn, is designed to
accept an additional steel cable that lets you adjust the tilt angle of the
MID/HIGH UNITs. The proper angle for the Mid/High units depends on
the height at which they are suspended and of course the type of venue.
The tilt angle can be varied slightly by means of the eight-position angles
on the rails as well as by the tension exerted by a cable attached to the
rail on the rear panel.
CAUTION! Always make absolutely sure that the points at which you attach the
Mid-High units (e.g. aluminum cross beam or a rigging point in the ceiling of the
venue) have sufficient load-carrying capacity and satisfy the applicable safety
standards. If you are in doubt, be sure to seek the advice of a structural engineer,
rigger or the venue's technician.

2.4 Double Projector System

You can add a second Projector system to expand the standard
PROJECTOR system setup. Please follow the instructions on setting up the
PROJECTOR components SUB 1, SUB 2 and MID-HIGH in section 2.1.
Note:
To prevent phase cancellation, place the PROJECTOR system so that the
side panels are set at an angle of 25° relative to each other. The edges of
the back panels should be set to the same height and they should touch
each other. A distance of some 30 cm (1 ft.) between the two front faces
of the cabinets will give you an angle of 25°.
25°
This 25° angle is the best possible compromise for the majority of
applications. Angles between 20° and 30° are possible, depending on
local factors such as the height, depth or width of the venue and the
distance between the loudspeakers and the walls.
