SR-C8S

The speaker shall be a two-way component module designed for use in a

modular line array system. The low-frequency section shall consist of

one 8" (20cm) Neodymium woofer. The high frequency section shall consist

of two compression drivers, each having a 1" (25 mm) Neodymium driver.

The high frequency waveguide shall consist of two throat sections

feeding a single shared mouth, with each throat section incorporating 8

paths of equal length from the driver throat to the waveguide mouth to

obtain effectively isophasic output for maximum efficiency of operation

in a line array system. The speaker input connectors shall include screw

terminal connections for LF and HF inputs and two Neutrik NL4 type

sockets, wired in parallel for pass-through to additional speakers.

The

speaker shall meet the following performance criteria. Power handling

in biamp mode: Low Frequency input: 360 W continuous program; High

Frequency input: 180 W continuous program. Power handling in single-amp

mode: 360 W continuous program. Frequency response (10 dB below rated

pressure sensitivity, with recommended crossover and equalization): 65

Hz to 20 kHz. Sensitivity (1 W at 1 m) in bi-amp mode: Low Frequency: 95

dB; High Frequency: 110 dB. Sensitivity (1 W at 1 m) in single-amp

mode: 98 dB. Rated impedance in bi-amp mode: Low Frequency: 16 ohms

nominal; High Frequency: 16 ohms nominal. Rated impedance in single-amp

mode: 16 ohms nominal.

The speaker's horizontal and vertical

coverage shall be tailored for use in a line array consisting of

multiple units from the same series arranged one above the other so that

each pass-band section forms a vertical line. The horizontal coverage

shall be 110 degrees nominal. The vertical coverage shall be 15 degree nominal. Extending the vertical

coverage area shall be possible by stacking multiple units from the same

series. The consistency of coverage shall not be degraded when multiple

units are stacked. The combined vertical coverage of multiple units,

when stacked, shall be adjustable from that of a straight line array

(coverage area defined by the height of the array) to a curved array,

with the combined coverage angle adjustable in 1 degree increments.

The

speaker enclosure shall be made of plywood and finished with black

urethane paint. The speaker grille shall be made from a single punched

steel plate and finished with black paint. The dimensions (W × H × D)

shall be 526.6 × 293 × 294 mm (20.73" × 11.54" × 11.57") and weight shall

be SR-C8S: 16 kg (35.27 lb). The speaker

enclosure shall be equipped with M8 threaded steel plates for the secure

attachment of optional accessory brackets.
The loudspeaker shall be TOA model SR-C8S.
The cluster bracket shall be TOA model SR-CL8.
The rigging frame shall be TOA model SR-RF8.
The tilt joint bracket shall be TOA model SR-TP8.
