This QSC SC-414 4-Way Screen Channel Loudspeaker, Tri- or Quad-Amp the mid, high, and very high frequency components of four-way screen channel loudspeaker system for high performance cinema applications. It was designed to operate with and be directly mounted on QSC’s cinema low frequency enclosures.
The high frequency horn is a low-distortion waveguide providing highly articulate dialogue without the coloration associated with conventional horn loudspeakers. Both horns feature broad horizontal and vertical coverage to ensure audio integrity is delivered to every seat in the auditorium. The driver assemblies are mounted on an adjustable pan and tilt bracket that has an integral aiming sight, simplifying installation.
The MHV-1090 includes a driver protection and high-very high frequency crossover network to assure reliable operation. DC blocking capacitors protect against DC or low-frequency signals that could damage an unprotected driver. A 12 dB per octave crossover seamlessly blends the high and very high frequency elements when operated in tri-amp mode. Outboard processing is required to form the crossover between the low, mid, and high-very high frequency drivers.
