SR-18 Surround Loudspeaker
Introduction
The SR-18 Cinema Surround Loudspeaker offers high power handling, excellent sensitivity, and
extended bass response in a very compact enclosure. The high power handling and rugged plywood
enclosure are optimized for the task of digital soundtrack reproduction.
Instead of being tuned as an individual unit, the SR-18 features Array Optimized Tuning (AOT). The
crossover is voiced for flat low frequency response when used in an array on a theatre wall. Conven-
tional loudspeakers are voiced as a single unit.
The SR-18 features a high power long-throw 8” (203mm) low frequency transducer for smooth,
extended bass response. The high frequency section combines a 1” (25mm) titanium diaphragm com-
pression driver with a constant directivity horn for very high output capability and wide, even high
frequency coverage. The 100 watt continuous power rating provides absolute reliability.
The compact black enclosure with black grille blends into any theatre decor. The baffle’s built-in 15°
tilt places the loudspeaker at the optimum coverage angle for most applications. The Quick Mount
bracket design allows for fast installation. The loudspeaker-half of the bracket comes pre-installed
on each SR-18. The Quick Mount wall bracket is purchased separately to allow shipment to the job
site ahead of the loudspeakers. A U-bracket is also available in lieu of the Quick Mount bracket sys-
tem.

Connections
The SR-18 has barrier strip screw terminals that accept up to #10 AWG stranded loudspeaker wire.
Input- Connect the amplifier’s output signal to the loudspeaker’s INPUT terminals. Observe proper polarity. Use the largest wire size and shortest
length for the application.
Output- The SR-18 has two terminals marked OUTPUT. These terminals are connected in parallel to the INPUT terminals and can be used for con-
necting multiple SR-18 enclosures in parallel with one another. Connect the OUTPUT terminals to the next loudspeaker’s INPUT terminals. Observe
proper polarity of connections.
Warnings and Important Notes
NOTE! Maintain proper loudspeaker connection polarity throughout the entire system for maximum performance.
NOTE! Ensure that the amplifier driving the parallel loudspeakers is rated to drive the lower impedance (Example: 4 enclo-
sures in parallel will yield 2 ohms impedance, nominally).
Use QSC’s Quick Mount bracket for wall mounting or U-bracket for wall mounting. Enclosure is not designed to be sus-
pended, flown, or rigged by any other method. Do not suspend, fly, or rig this enclosure.
Always keep sound pressure levels in the listening area below levels that can damage human hearing.
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. Servicing
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, cabi-
nets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed or non-load rated com-
ponent 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 condi-
tions of the installation and any possible short-term unexpected overloading. Never exceed the rating of the hardware or
equipment. Consult a licensed, professional engineer when any doubt or questions arise regarding a physical equipment
installation.

Altavoz envolvente SR-18
Introducción
El altavoz SR-18 de sonido envolvente para salas de cine ofrece un manejo superior de la potencia, exce-
lente sensibilidad y respuesta extendida a los bajos en una caja muy compacta. El manejo superior de la
potencia y la resistente caja de madera contrachapada están optimizados para la tarea de la reproducción
digital de la pista de sonido.
En lugar de estar afinado como una unidad individual, el altavoz SR-18 ofrece la configuración de afi-
nación óptima (Array Optimized Tuning, AOT). El cruce está ajustado para una respuesta de baja frecuen-
cia plana cuando se usa en la configuración de una pared de teatro. Los altavoces convencionales están
ajustados como unidades sencillas.
El altavoz SR-18 tiene un transductor de baja frecuencia de alta potencia y largo alcance de 8” (203 mm)
para dar una respuesta extendida uniforme a los bajos. La sección de alta frecuencia combina un excita-
dor de compresión de diafragma de titanio de 1” (25 mm) con un cuerno de directividad constante para
una capacidad de salida muy alta y una cobertura de frecuencia alta, ancha y uniforme. La capacidad nom-
inal de potencia continua de 100 watts proporciona una fiabilidad absoluta.
La compacta caja negra con rejilla negra se adapta a la decoración de cualquier teatro. El dispositivo de
inclinación de 15° integrado en la pantalla acústica coloca el altavoz en el óptimo ángulo de cobertura
para la mayoría de las aplicaciones. El diseño del soporte Quick Mount permite una instalación rápida. La
mitad del soporte del altavoz viene instalado en cada altavoz SR-18. El soporte Quick Mount de montaje
en la pared se compra por separado para permitir su entrega en el lugar de trabajo antes de la entrega de
los altavoces. También hay disponible un soporte en U en lugar del sistema de soporte Quick Mount.
