Introduction
The MHV-1090F system provides the mid, high, and very high-frequency components of a DCS 4-way loudspeaker system. It is designed specifically
for large format cinemas and other applications where a point source surround channel or screen channel must be suspended or flown rather than
mounted on a platform or floor.
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 horn and driver assemblies are mounted in a rugged, tour-grade plywood enclosure designed for safe suspension via M10 attachment points.
Heavily braced, tour grade construction provides great strength while keeping weight to a minimum. The rear panel is removable for access to the
drivers and HF/VHF crossover if service should ever be necessary.
The MHV-1090F 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 and allows operation in tri-amp mode. Outboard processing, such as the DCP 300 or DCM 30D, is required to provide
the active crossover between the low, mid, and high/very high-frequency drivers and separate amplifiers are required for the low, mid, high/very high-
frequency channels.
The MHV-1090F is pre-assembled to reduce field assembly time. Sixteen M10 attachment points provide safe and secure means to suspend the
enclosure via M10 forged eyebolts (not included) or user-supplied brackets.
Suspension
The MHV-1090F comes with 16 M10 attachment points and bolts installed on the enclosure. Only remove the required bolts for mounting and leave
all other bolts installed to insure that the enclosure is properly sealed and retains full strength. We recommend the use of serviceable thread locking
compound when installing the bolts to prevent loosening due to vibration. Use only load rated hardware.
The LF-4215-8F and MHV-1090F have the exact same external dimensions and attachment points. They can be supported individually or as a pair,
depending on what works best for the application. The boxes can be arrayed vertically and horizontally. When paired together, it is recommended that
the mounting structure connects both boxes to the suspension system rather than suspending the boxes from one another. Commercially available
uni-strut or other custom fabricated brackets can be used.
Suspending the system from the top rear attachment points results in a slight down angle that may be close to the desired aiming for many
installations. The bottom attachment points can be used for a pull-back cable to fine tune the tilt of the system.
