DESCRIPTION

The Altec Lansing PS-92 loudspeaker is a

two-way, factory assembled system capable
of producing medium to high acoustic output
from a small package. It is well suited for
medium to high level sound reproduction in
houses of worship, audio-visual presenta
tions, conference rooms or other smaller
acoustic environments. The PS-92 utilizes a
12 inch (30.5 cm) duplex® loudspeaker with
a wide dispersion dome tweeter. Smooth tran
sition at crossover is accomplished by a dual section
12 dB/octave network with a center frequency
of 1.5 kHz. The PS-92 is also fully pro

tected by means of an auto-reset circuit
breaker at the input of the system which will

not allow the inexperienced operator to
damage the system's components. The en
closure is constructed of 3/4-inch Enviro-

board™ covered in a protective light gray
carpet that is more durable than conven
tional coverings. The enclosure is supplied
with a removable metal grille which adds
to the duability. Inset handles on either
side of the unit allow for easy transporta
tion. A built-in stand mount compliments
the versatility of this unit.

The Altec Lansing PS-92 is the ideal

choice where a flexible, portable, inexpen
sive loudspeaker system must project out

standing live voice or music reproduction.
