3.4 Double D.E.A.CON system
The double system comprises 4x D.E.A.CON
mid/high units, 4x D.E.A.CON Sub A, and
4x D.E.A.CON Sub B.
Wiring also follows the "top-to-bottom" order
described above. To route the sound mixer signal to
the second D.E.A.CON stack, use the Through socket
on the first mid/high-range enclosure. Use a micro-
phone cable. The XLR jacks should be configured as
follows: 1= ground, 2= +, 3= -
Installation:
With the double D.E.A.CON system, it is especially
important to pay attention to the installation of the
two stacks. The cabinets are constructed so that the
bevelled sides of the enclosure indicate the correct
installation (at a splay angle—see illustration). This
is essential to ensure an optimal acoustic coupling
of the two enclosures. Otherwise undesired nulls or
phasing effects in the power bandwidth may result.
The subwoofers can, of course, also be placed side-
by-side.
Question
Can I connect enclosures other than the D.E.A.CON
Subwoofer Sub A or Sub B to the D.E.A.CON
mid/high-range enclosure?
Answer
The system components are acoustically perfectly
matched and can only be operated in the indicated
3.5 Flying the D.E.A.CON mid/high unit
For flying the enclosure, use the special HK AUDIO
flying mount for the D.E.A.CON mid/high-range
enclosure. For mounting, loosen the laterally sunken
M10 pins. Tightly screw the flying mount via its
flanges to the cabinet. The enclosure may be tilted at
any angle. Just loosen the lateral knob and manually
screw it tight. The dovetailed synthetic plates will
ensure that the enclosure does not inadvertently
swivel.
Note: To ensure safety, only use separate lifting
accessories that have been tested (e.g. half-couplers,
TV spigots, collars, etc.)!
The supports or tripods used must be designed to
bear the corresponding load (weight of D.E.A.CON
mid/high unit = 39.7 kg).
3.6 Using the D.E.A.CON tilt unit
Mounting the optionally available tilt unit is
extremely easy:
Just place the D.E.A.CON tilt unit with its bottom
plate onto the upper subwoofer, then place the
D.E.A.CON mid/high-range enclosure onto the
flange with the flange-holders (7.5° or 15°), just as
if you were placing the cabinet onto a tripod.
configurations. The use of other subwoofers can
have a negative effect on the sound, and may result
in damage to the enclosure (e.g. Sub A).
Sub A's speaker output socket is designed for a
(total) nominal impedance of 4 ohm, and under no
circumstances should anything less be used. Always
connect only one Sub B to the Sub A's speaker
output socket.
