Architectural Specifications; Horizontal 1/3 Octave Polars - JBL Control 29AV-1 Manual

Horizontal 1/3 Octave Polars

Architectural Specifi cations:
The loudspeaker shall consist of a 200 mm (8 in) low frequency
transducer, 25 mm (1 in) compression driver, and frequency dividing
network. The low frequency driver's voice coil shall be 50 mm (2 in) in
diameter.
Performance specifi cations of a typical unit shall be as follows: Usable
frequency response shall extend from 37 Hz to 18 kHz (10 dB below
rated sensitivity, half-space, no external equalization). Rated power shall
be at least 300 watts continuous program power for 100 continuous
hours duration (defi ned as 3 dB above a test signal of fi ltered random
pink noise conforming to IEC268-5). Measured sensitivity shall be at
least 90 dB-SPL (at 1 m [3.3 ft] with 2.83 V input, ave. 100 Hz to 10 kHz).
The input shall be switchable for use either at nominal 8 ohms, or on
a 70.7V or 100V distributed speaker line via built-in transformer.
Selectable taps shall nominally be 110W, 55W, or 28W on either a 70.7V
or 100V distributed speaker line, plus 14W on 70.7V line only.
The system shall be protected against damage from occasional
overpowering via full range limiting, which shall be inaudible during
activation. The compression driver shall be horn-loaded to cover 110
degrees by 85 degrees with a high degree of accuracy and the horn shall
be rotatable to achieve these coverages either in the horizontal or
vertical planes, regardless of cabinet orientation.
The cabinet and grille shall be paintable. The grille shall be secured
via screws to keep it in place when facing downward.
The low frequency transducer shall have woven kevlar cone and butyl
rubber surround, with the frame protected from direct weather
exposure. The compression driver shall be constructed with a titanium
diaphragm for weather resistance. The system shall withstand Mil Spec
810 testing with specifi ed durations with no effect on its acoustical
performance or structural integrity: salt spray (method 509.3), tempera-
ture (method 501.3 and 502.3), humidity (method 507.3) and ultraviolet
(method 505.3). Further, it shall pass Mil-Std-202F (method 101D) for salt
spray. The system shall have an IEC 529 splashproof rating of IP-X4.
For theft-deterrence, the installation access area shall be hidden
behind a snap-out cover on the front grille. The included ball mecha-
nism shall be internal to the cabinet. The cabinet shall have ten (10) 6 mm
mounting points, including 2 on each side and 3 on top and bottom and
an accessory U-bracket shall be available. The grille logo shall be
rotatable for proper orientation with loudspeaker mounted horizontally
or vertically.
The external wiring connectors shall be screw-down terminals. Overall
cabinet dimensions shall be no greater than 520 mm high x 306 mm
wide x 277 mm deep (20.5 x 12.0 x 10.9 in) and shall weigh no more
than 12.2 kg (26.8 lb). The fi nish shall be lightly textured black or white.
The system shall be the JBL Model C29AV-1 (or C29AV-WH-1) with
included InvisiBall ® (mounting system).
