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 from:

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,
3.7W 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
7.2ohms. Input connectors shall be push pins. The enclosure shall be constructed of high-impact polystyrene and fitted with a powder-coated steel grille, and M6 and M5 threaded inserts for optional accessories. Dimensions shall be 400 mm (15.75 in.) high x 292 mm (11.5 in.) wide x 240 mm (9.45 in.) deep. Net weight shall be 9.3 kg (20.5 lb).
The system shall be capable of producing average sound levels in excess of in the long term, and short-term peaks.
The loudspeaker system shall be the Electro-Voice Sx80TB (black) or Sx80TW (white).
