Electro-Voice PA60 - Manual

PA60
PA60M
Reentrant Paging Projector
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
