Electro-Voice PA430 Specifications

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 constant­directivity 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).

Installation

The PA430 has been designed to accommodate a wide range of mounting
and aiming requirements.

Mounting to wall, ceiling or to electrical boxes is accomplished without the
common requirement of adding a steel plate to the base. Bonding straps
may be used for mounting to beams. All mounting holes are knocked through
only as needed, preserving a seal in the remaining knockout areas.

Wiring is enclosed within the product base, providing physical protection of
wiring and personnel.

The mounting assembly provides three means of adjustment, allowing the
horn to be oriented for any coverage pattern desired. Adjustment is
accomplished with nuts that require minimal torque to maintain horn position
and may be tightened by hand.

During installation, after punching out the desired attachments, the base
and horn are loosely secured with one screw. This leaves hands free to
wire nut the product zip cord and feed wiring together. After tucking wire
connections into the electrical box or base, install remaining screws.

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,

70.7 volt or 25 volt line, the power setting depends upon the amplifier output
that is used, 100 volt, 70.7 volt or 25 volt.

CAUTION: When connected to a 100 volt or 70.7 volt line, do not use the
switch settings marked “DO NOT USE,” as this may result in excessive
power driving the PA430T.

Low-Frequency Driver Protection

For proper system operation, program information should be highpassed
at 300 Hz or higher with at least a 6 dB per octave slope filter. This is best
accomplished before the power amplifier using a low-level crossover;
however, protection of amplifier and paging projector may alternately be
accomplished using a capacitor in series with the projector. Table 1 gives
values for such protection capacitor. Polyester capacitors are recommended,
but non-polarized electrolytic or two series back-to-back connected
electrolytics, each of twice the value shown, may be used.
