60° Angle bracket (E6502)
Ring & Screw fittings for detented
rigging tracks (E6530/E6531)
WARNING!
(4.0E) 1220/1222
1220/1222 Accessories
1220/1222 loudspeakers are fitted with detented rigging tracks at
the top, bottom and rear of the cabinet. Two types of fitting can be
used with these tracks.
E6530 Ancra ring fitting
The ring fittings allow single 1220/1222 loudspeakers or two cabinet
1220/1222 clusters to be flown at a precisely defined vertical angle
without the need for additional stabilising guylines. Preset flying
angles b48° and -12° are obtained by using the ring fittings
in certain positions in the detented tracks.
The table below shows the resulting vertical flying angles using a
pick-up (flying) point on the cabinet top or upper rear detented
track. Column A gives the flying angles for single loudspeakers, whilst
column B gives the angles for two cabinet clusters.
A single ring fitting will support the weight of a single 1220/1222
loudspeaker with a 12x load safety factor.
E6531 Ancra stud fitting
The screw fitting is for use with detented rigging tracks and has a 3/
8” threaded stud fitted with a flange nut. The screw fitting is used to
attach the E6502 60° Angle bracket.
E6502 60° Angle bracket
The 60° Angle bracket is used, as shown below, to precisely align two
1220/1222 loudspeakers next to each other. The resulting two
cabinet cluster has a 120° dispersion angle.
The bracket is fixed to the 1220/1222 loudspeaker rear panel
detented rigging tracks with two E6531 Ancra stud fittings. We
recommend using two brackets, one attached to the upper rear
panel tracks and the other to the lower tracks.
The hole in the centre of the Angle bracket is for use only to attach a
stabilising guyline if needed. The cluster itself must be flown using
E6530 Ancra ring fittings attached to the upper flying tracks.
Under no circumstances should you fly a speaker
cluster using the Angle bracket as a suspension
(flying) point!
