General Product Description
The PA430 and PA430T are 30-watt constant-directivity paging
projectors for use in any public address or paging application.
The drivers employ rugged phenolic diaphragms, 1.5 inch diameter
voice coils and “rim centered” ferrite magnet structures for long life
and reliability under extreme operating conditions.
A 12 inch connecting cable, color coded for phase, is provided for
connecting to the PA 430 and PA430T.
The transformer model (PA430T) includes connections for 25V,
70.7V, and 100V distributed systems and a screwdriver-operated
power tap select switch. (Patent #4, 775, 766)
A nominal 60° horizontal by 40° vertical coverage pattern together
with a low-frequency cutoff of 350 Hz provides excellent articulation
in demanding applications.
The PA430 (PA430T) is molded from high-impact ultraviolet-inhibiting
acrylic-styrene-acrylonitrile (ASA). A positive lock, super tough nylon
swivel base and rear housing provides maximum mounting flexibility
and ease of installation. (Patent #4,984,278)
Ideal for both indoor and outdoor applications, these drivers are
well suited for any installation requiring rugged, reliable performance.
Architects’ and Engineers’ Specifications
The loudspeaker(s) shall be an integral driver and constant-
directivity horn utilizing a rugged phenolic diaphragm and
high-temperature-rated, 1.5-inch diameter voice coil.
The axial frequency response will extend from 400 to 6,500 Hz,
and the horn shall exhibit a low-frequency cutoff of 350 Hz. Sound
pressure level will be 107 dB (1 W/1 m) with a 500 to 5,000 Hz
pink-noise signal applied, and the horn will produce a horizontal
beamwidth of 60° and a vertical beamwidth of 40° from 1 kHz to 10
kHz.
The loudspeaker(s) shall be capable of handling a 30 watt, 500 to
5,000 Hz pink-noise signal with a 6 dB crest factor for a period of 8
hours.
The horn shall be molded, high-impact acrylic-styrene-acrylonitrile
(ASA) capable of satisfactory mechanical performance in the
temperature range from -4°C (-40°F) to 71°C (160°F) and not subject
to sunlight embrittlement. Other major external speaker parts shall
be molded nylon, finished in mesa tan to match the horn. All

components shall be resistant to damage from weather, moisture
and fungus.
A positive-lock swivel bracket shall provide orientation adjustment
in all three places. Adjustments are made by loosening one or both
of the locking nuts on the mounting hoop.
The loudspeaker(s) shall be 22.6 cm (8.9 in.) high, 30.7 cm (12.1
in.) wide and 31.0 cm (12.2 in.) deep - PA430; or 35.8 cm (14.1 in.)
deep - PA430T.
The loudspeakers shall be the PA430, which has a nominal
impedance of 8 ohms and weighs no more than 1.4 kg (3.0 lb); and
the PA430T, which includes a 100V/70.7V/25V line-matching
transformer, and has a nominal impedance of 8 ohms and weighs
no more than 1.7 kg (3.8 lb).

... Transformer Model (PA430T) A transformer and power selector switch are installed in the rear housing. The level of the PA430T may be adjusted by moving the switch setting (see Table 2) using a coin or screwdriver; turn clockwise to increase the power. Since the same switch and transformer are used for either the 100 volt, 70 ...
