HF-63X1 and HF-63X2
High Frequency Component
Introduction
The HF-63X1 and HF-63X2 are the high frequency components of full-range,
two-way screen channel loudspeaker systems for high performance cinema
applications. The HF-63X1 is designed specifically for use with QSC’s LF-
3115 low frequency loudspeaker and the HF-63X2 for the LF-3215 loud-
speaker.
The HF-63X1/X2 high-frequency system features a large format, 2.5”
(63.5mm) titanium diaphragm compression driver mounted on a custom
designed high-frequency cinema horn with an adjustable pan and tilt
bracket. The horn features broad horizontal and vertical coverage angles to
ensure coverage of every seat in the auditorium. The horn is a low-distortion
waveguide providing highly articulate dialogue without coloration associ-
ated with conventional horn loudspeakers. Equipped with a passive cross-
over providing tailored output for the LF-3115 or LF-3215, no additional
signal processing is required.
The HF-63X1/X2 components come pre-assembled to reduce field assembly
time. Three bolts are all that are required to secure the HF-63X1/X2 to the
top of a QSC low frequency loudspeaker. Threaded inserts in the LF enclo-
sures and matching punched hole pattern in the HF-63X1/X2 make mounting
to the low frequency enclosure simple.
Mounting
Refer to the illustration for mounting information. The HF-63X1/X2 attaches
to the top of the LF-3115 or LF-3215 with three 5/16-18 bolts, 0.75” long,
with lock washers. This hardware ships installed on the low frequency cabi-
net. We recommend the use of serviceable thread locking compound when
installing the bolts to prevent loosening due to vibration. Aim the horn in the
horizontal plane (pan) before tightening. Adjust the vertical tilt with the
bracket adjustment.
Install in accordance with QSC Audio Product’s instructions
and a licensed, professional engineer. Only use attachments,
mounts, accessories, or brackets specified by QSC Audio
Products, Inc. Refer all servicing to qualified personnel. Ser-
vicing is required when the apparatus has been damaged in
any way.
WARNING! Before placing, installing, rigging, or suspending
any speaker product, inspect all hardware, suspension, cab-
inets, transducers, brackets and associated equipment for
damage. Any missing, corroded, deformed or non-load rated
component could significantly reduce the strength of the
installation, placement, or array. Any such condition
severely reduces the safety of the installation and should be
immediately corrected. Use only hardware which is rated for
the loading conditions of the installation and any possible
short-term unexpected overloading. Never exceed the rating
of the hardware or equipment. Consult a licensed, profes-
sional engineer when any doubt or questions arise regarding
a physical equipment installation.
