Electro-Voice PA60 User Manual

PA60

General Product Description

The PA60 is a 60-watt reentrant paging projector for use in any
public address or paging application.

The driver employs rugged phenolic diaphragm, 1.5-inch diameter
voice coil, and strontium ferrite magnet structure for long life and
durability under extreme operating conditions.

The PA60M is identical to the Model PA60, but is white in color and
is designed for marine use with stainless steel hardware.

A 13.5-inch SJTO-18-2 cable, phased and color-coded, is provided
for connecting to the PA60.

A nominal 80° horizontal by 50° vertical coverage pattern together
with a low-frequency cutoff of 400 Hz provides excellent articulation
in demanding applications.

The PA60/PA60M is molded from high-impact ultraviolet inhibiting
ABS (acrylonitrile butadiene styrene).

Ideal for both indoor and outdoor applications, these horns are well
suited for any installation requiring rugged, reliable performance at
a low cost.

Architects’ and Engineers’ Specifications

The loudspeaker shall be an integral driver and reentrant horn
utilizing a rugged phenolic diaphragm and high temperature rated

1.5-inch diameter voice coil.

The axial frequency response will extend from 600 to 6,500 Hz and
the horn shall exhibit a low frequency cutoff of 400 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 80° and a vertical beamwidth of 50° at 2.0 kHz.

The loudspeaker shall be capable of handling a 60 watt, 500 to
5,000 Hz pink noise signal with a 6 dB crest factor for a period of
eight hours.

The horn shall be molded high-impact acrylonitrile butadiene styrene
(ABS), capable of satisfactory mechanical performance in the
temperature range from -40°C (-40°F) to 71°C (160°F) and not
subject to sunlight embrittlement. Other major external speaker parts

PA60M

Reentrant Paging Projector

shall be diecast zinc finished in mesa tan baked enamel to match
the molded horn parts. The Model PA60M shall have external parts
of stainless steel and will be white in color. All components shall be
resistant to damage from weather, moisture, and fungus.

A serrated, positive-lock swivel bracket shall provide orientation
adjustment in all three planes. Vertical adjustments are made by
loosening a single wingnut on the mounting base.

Dimensions shall be 28.0 cm (11.0 in.) high by 16.5 cm (6.5 in.)
wide by 21.6 cm (8.5 in.) deep. Net weight shall not exceed 1.8 kg
(4.1 lb). The loudspeaker shall be the PA60/PA60M.

Installation

The base may be easily removed to simplify speaker installation by backing
off the single wingnut to approximately the end of its bolt. Remove the base
with a sliding motion. It is not necessary to completely remove either
the wingnut or its bolt. Later, after the base is mounted, the speaker may
be reinstalled on the base with a similar sliding motion, adjusted to any
angular position, and the wingnut tightened.

Mounting the Base

The removable mounting base has three evenly-spaced holes on a 60.3
mm (2.38 in.) diameter circle. This diameter is small enough to be
conveniently mounted on the cover of a standard 4-inch square or octagon
electrical outlet box. The base may be used as a template. In addition, the
base is slotted for mounting with 1/2-inch steel banding material. Banding
tools and materials are available commercially and permit attachment to
I-beams, pillars, or similar structural supports, where screwmounting is
impractical. Finally, the base may also be attached to many structural
supports with small C-clamps providing appropriate safety measures are
observed.

Polar Response

The directional characteristics of the PA60 were measured by running a
set of horizontal/vertical polar responses in Electro-Voice’s large anechoic
chamber, at each one-third-octave center frequency. The test signal was
one-third-octave pseudo-random pink noise centered at the indicated
frequencies. The measurement microphone was placed 6.1 m (20 ft.) from
the horn mouth, while rotation was about the waveguide geometric apexes.
These axes of rotation are quite close to the apparent (acoustic) apexes
across the frequency range of measurement. Errors attributable to the slight
differences between the geometric and acoustic apexes are reduced to an
inconsequential level by the relatively long, 20-foot measuring distance.
The horn was suspended freely with no baffle. The polar plots shown in
Figure 1 display the results of these tests. The center frequency is noted on
each plot. The wider plot on each chart is the horizontal polar (–) and the
narrower plot is the vertical polar (– – –).

Beamwidth

A plot of the PA60’s 6-dB-down total included beamwidth angle is shown in
Figure 2 for each one-third-octave center frequency.

Frequency Response

Figure 3 shows the axial frequency response of the PA60. It was measured
at a distance of 1 meter, using a swept sine wave.
