G712-PRO
The system is to consist of a 3-way loudspeaker cabinet, either actively or passively separated, which is driven and protected by a special controller output stage. The loudspeaker should contain a 12 inch loudspeaker in a bass reflex tuned cabinet for the low frequency range. The loudspeakers used should be impregnated weatherproof. In the midrange, a pressure chamber driver with a 3.5-inch ring diaphragm arranged coaxially in front of the high-frequency driver is to operate. In the high frequency range, a pressure chamber driver with 1.75 inch ring diaphragm is to work. The pressure chamber drivers used should be coupled to a common asymmetrical horn. Its radiation characteristics should be 90° horizontal and 60° vertical and rotatable in 90° steps. The continuous load capacity of the system should be 1,000 watts RMS. The loudspeaker should have a nominal impedance of 8 Ohm. The usable system bandwidth should be 60 Hertz to 21,000 Hertz (-3 dB). The maximum peak sound pressure level should be 134 dB, measured with pink noise at a distance of 1 m, under half-space conditions and with a crest factor of 6. The loudspeaker cabinet should be made of birch multiplex and sealed with a weather- and moisture-resistant polyurea coating (PU). The trapezoidal housing should have 35° and 55° inclinations, which make the use as a stage monitor more flexible. The front of the loudspeaker should be equipped with a ball-proof protective grille, which is backed with acoustically neutral foam. Its physical dimensions should be 348 mm in width, 630 mm in height and 320 mm in depth. The loudspeaker shall weigh 21.5 kg. The loudspeaker should have M6 and M8 mounting points with which special accessories can be mounted. The speaker should have an integrated stand flange. With optional flying brackets, the speaker can be mounted horizontally and vertically. The system should be available in left and right speaker versions. The loudspeaker should be connected via two 4-pole SpeakON sockets. The manufacturer's warranty shall be 5 years.
