Acoustic system QSC Cinema SC-434

QSC Cinema SC-434

Front 4-way speaker system for cinemas with choice of connection to amplifiers in tri-amp and quad-amp modes. A low distortion level of the waveguide provides high detail of speech. A small depth (20") makes it easy to install a speaker system. The SC-424 consists of a low-frequency cabinet LF-4315 with two 15" (381 mm) speakers and a MHV-1090 MF + HF with a 10" mesh tweeter and a neodymium coaxial HF radiator with membranes 3,5" (90 mm) and 1,75" (44 mm).

The MHV-1090 provides a 90° coverage angle in the horizontal plane and a vertical angle adjustment of + 20° to -30°. The features of the acoustic system certainly include the coaxial design of the high-frequency compression driver. By QSC, this is referred to as the "HF/VHF diaphragm", that is, the high frequency (HF) and microwave (diaphragm) diaphragms. The coaxial RF emitter consists of two membranes, one reproduces sound in the frequency range of 1700-6000 Hz. The second operates from 6 kHz and higher. Thus, the best detail and the extended dynamic range in the high frequency range are achieved.
