HF-63 High Frequency Component
Introduction
The HF-63 is the high frequency component of two-way, biamplified screen
channel loudspeaker systems for high performance cinema applications. It
was designed to operate with and be directly mounted on QSC’s LF-3115 or
LF-3215 cinema woofer.
The HF-63 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 fea-
tures broad horizontal and vertical coverage angles to ensure coverage of
every seat in the auditorium. The horn is a low-distortion waveguide provid-
ing highly articulate dialogue without coloration associated with conven-
tional horn loudspeakers.
The HF-63 includes a driver protection and equalization network to assure
reliable operation. DC blocking capacitors protect against DC or low-fre-
quency signals that could damage an unprotected driver. Power limiter cir-
cuitry protects the driver from over-powering and a response correction filter
smoothes the frequency response of the horn/driver combination. Outboard
processing is required, however, as the response correction filter is not a
crossover.
The HF-63 components come pre-assembled to reduce field assembly time.
Three bolts are all that are required to secure the HF-63 to the top of a QSC
low frequency enclosure.
Mounting
Refer to the illustration for mounting information. The HF-63 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 cabinet. We
recommend the use of serviceable thread locking compound when installing
the bolts to prevent loosening due to vibration. Aim the horn in the horizon-
tal 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.

Connections
HF INPUT Terminals
The HF-63 has barrier strip screw terminals that accept up to #10 AWG (5.3mm 2) stranded loudspeaker wire. Connect the amplifier’s
high frequency output signal to the loudspeaker’s HF INPUT terminals. Observe proper polarity; amplifier’s + signal to loudspeaker +
HF INPUT, amplifier’s - signal to loudspeaker - HF INPUT. Use the largest wire size and shortest wire length for the application.
NOTE! Maintain proper loudspeaker connection polarity throughout the entire system for maximum performance.
Do not apply full range signal to the HF-63! There is no crossover in the HF-63, only an equalization and protection
network. All required signal processing must be done before the signal is applied to the HF-63.
HF OUTPUT Terminals
The HF OUTPUT terminals are factory-connected to the compression driver. These terminals should ONLY be connected to the HF-63’s
compression driver.

Note: The HF-63 connection enclosure
does not contain a crossover network!
Ensure only high frequency signal is
applied to HF INPUT terminals or com-
pression driver damage will occur.
