tional, federal, state, and local regulations.
It is the responsibility of the installer to en-
sure the Sx80T is safely installed in accor-
dance with all such regulations. If the Sx80T
is suspended, Electro-Voice strongly recom-
mends that the system be inspected at least
once a year. If any sign of weakness or dam-
age is detected, remedial action should be
taken immediately.
The Sx80T enclosure contains seven M6 in-
serts and (see Figure 6) which are built into
the enclosure for the purpose of suspension.
These inserts can be used with either the
Sx80MB mounting bracket from Electro-
Voice, or with an OmniMount
®
Series 75
mounting system.
Sx80MB
The Sx80MB is a universal U-bracket de-
signed to allow the suspension of the Sx80T
at any angle and orientation from the wall or
ceiling (See Figures 6 and 8). It uses M6
inserts on the top and the bottom of the en-
closure. There is an extra M6 insert on the
top of the enclosure for a safety chain. Full
instructions are included in the Sx80MB
engineering data sheet.
OmniMount
®
Series 75
Four M6 threaded inserts and screws are lo-
cated on the rear of the Sx80T for use with
the OmniMount
®
Series 75 support system.
A safety chain should be used to ensure safe
operation. Full instructions for the
OmniMount
®
Series 75 can be obtained

Transformer Settings
A transformer and power selector switch are
installed in the rear of the enclousre. The
level of the Sx80T may be adjested by chang-
ing the switch setting using a screwdriver.
Turning the switch clockwise increases the
power. Since the same switch and transformer
are used for either the 100-volt or 70-volt line,
the power setting depends upon the amplifier
output that is used, 100-volt or 70-volt.
CAUTION: When connected to a 100-volt
line, do not use the switch setting marked
“DO NOT USE,” as this may result in ex-
cessive power driving the Sx80T or exces-
sive distortion.

Specifications
The loudspeaker shall consist of a 200-mm
(8.0-in.) low frequency transducer in a
vented, trapezoidal-shaped enclosure: a
DH2005 high-frequency compression driver
with a pure titanium diaphragm coupled to a
90° X 65° constant-directivity horn molded
into the front baffle of the enclosure. The
system will use a passive crossover-equal-
ize network with protection for the high-fre-
quency driver. The loudspeaker shall meet
the following performance criteria: fre-
quency response of 65 to 20,000 Hz, -3 dB;
maximum power handling of 60 watts long
term and 240 watts short term with switch
selectable taps for 60 W, 30 W, 15 W, 7.5 W,
3.7 W and 1.8 W, with a shaped random-
noise input per ANSI/EIA RS-426-A 1980;
sensitivity of 92 dB SPL at 1 meter with a 1-
watt, 300-2,000-Hz pink-noise input; 6-dB-
down horizontal coverage angle of 90° + 34°/
-27° in the 2,000- to 20,000-Hz range; 6-dB-
down vertical coverage angle of 65° + 31°/-
4° in the 2,000- to 20,000-Hz range; cross-
over frequency of 2,200 Hz; nominal imped-
ance of 8 ohms and minimum impedance of
7.2 ohms. Input connectors shall be push
pins. The enclosure shall be constructed of
