7. Rigging concept and devices
The d&b flying system provides flexibility for scaling a
complete C3/C4/C7 sound reinforcement system. The
flying system is designed to aim and position the
loudspeaker cabinets in a way that ensures an
optimized acoustic result.
All d&b flying hardware is Type Approved to the
German safety regulation BGV C1.
7.1. The components
7.1.1. MAN Flying stud and CF4 Stud plate
C3, C4-TOP, C4-SUB, C7-TOP and (optionally) MAX
cabinets are fitted with MAN CF4 stud plates which
are designed to take the MAN Flying stud. The MAN
Flying stud (also called the D-Ring) is the central
component of the flying system. It is an easy to fit,
self-locking device which connects the cabinet to the
load bearing chains.
7.1.2. Load bearing chains
According to BGV C1, the maximum allowed load is
560 kg (1234 lb) which is approximately the weight of
8 x C4 and 1 x MAX or 8 x C3 cabinets, including
fittings.
The chains are available in different lengths:
− 11-link chains are used to suspend a loudspeaker
column from a sub bar.
− 23-link chains are used to fly cabinets with a
vertical angle between them of approximately 5°.
23-link chains are also recommended for use as
top chains (sub bar to the top cabinet) for 6-8
deep columns.
− 1° chains are used to connect cabinets either to
gain space between the columns or to couple C3s
for the far field.
− 2.5° chains are the next angle increment to C3
cabinets.
− 47-link shortening chains (left and right versions),
are used to adjust the vertical angle between
cabinets in 5° increments.
7.1.3. Ratchet strap
The ratchet strap is used to set the vertical angle of
the loudspeaker column. It is not a load bearing
component in the whole assembly. d&b offers 2 ton,
12 m (39 ft) straps for columns up to 8 cabinets deep.
7.1.4. Hinge set
The hinge fits to the rear of the cabinets in a column
to maintain the alignment. It has a recessed slot to
accommodate a ratchet strap that speeds up rigging.
The hinge set can be retrofitted to all existing C3, C4
(402)-TOP, C4 (402)-SUB and C7 (702)-TOP cabinets.
It also can be used in ground stack situation to stop
cabinets from moving.
