2-1984. Utilizing audio band 20 Hz to
20 kHz pink noise with peaks over four
times the RMS level, this strenuous test
signal assures the user that every portion
of this system can withstand todayÕs high
technology music. The test signal contains
large amounts of very low frequency ener-
gy, effectively simulating the frequency
content of live music situations. The full
measure of high frequencies in the test
signal allows for exposure of the speaker
to synthesized tones that may extend
beyond audibility. This rating is contingent
on having minimum 3 dB of amplifier
headroom available.
ARCHITECTURAL AND ENGINEERING
SPECIFICATIONS:
The loudspeaker system shall have an
operating bandwidth of 48 Hz to 18 kHz.
The output level shall be 100 dB when
measured at a distance of 1 meter with
an input of 1 watt. The nominal imped-
ance shall be 8 ohms. The continuous
power handling shall be 350 watts, maxi-
mum program power of 700 watts, and a
peak power handling of 1,400 watts, with
a minimum amplifier headroom of 3 dB.
The peak SPL with inaudible distortion
shall reach 133 dB with music as a
source, when measured at a distance of
1 meter and driven to rated power. The
system shall utilize a 15" Black Widow
woofer and a 22XT compression driver
tweeter. The nominal radiation pattern
shall be 90 degrees in the horizontal plane
and 45 degrees in the vertical plane. The
cabinet is to consist of injection-molded
polypropylene of 1/4" nominal thickness,
with internal reinforcing ribs. A handgrip
shall be present on each side of the cabi-
net next to the woofer and a handle on the
top rear edge. A vinyl-coated perforated
metal grille shall be provided for woofer
protection. The cabinet shall incorporate
four tall sturdy rubber feet for floor stand-
ing use and four mounting point inserts
top and bottom for flying use. The outside
dimensions shall be 28 9/16" tall by
21 5/16" wide (11 1/2" wide in rear) by
17" deep. The weight shall be 56 lbs. The
input connection shall be made available
via two 1/4" phone jacks and two 4-pin
Neutrik Speakon connectors, all connect-
ed in parallel for full range use, and a
locking switch to select bi-amp use for the
Neutrik connectors and instant access
1/4" switching jacks for bi-amp use with
1/4" phone jacks. The loudspeaker system
shall be a Peavey model Impulse 500.
Warning! When use of
a stand is considered,
the Peavey S-1ª stand is rec-
ommended. Other stands may
not have a base sufficiently
wide enough for stability and
safety.
CAUTION! For permanent
outdoor installation, avoid
direct cone exposure to sunlight
and rain by tilting speaker down
and use a splash shield on top.
WARNING! Before
attempting to suspend
this speaker, consult a certified
structural engineer. Speaker can
fall from improper suspension,
resulting in serious injury and
property damage. Do not sus-
pend or mount any other prod-
uct or device from this enclo-
sure! Use only Grade 5 hard-
ware or better.
