Transient voltages from powering up source equipment can damage speakers if amplifiers are already turned on.
Make sure that amplifier volumes are set to their minimum settings and power up any system amplifiers LAST. It is
recommended that all system components be allowed to stabilize for few seconds before any source signals are
introduced or level setting adjustments are made. Similarly, when shutting systems down, turn all amplifiers off first,
before powering down any other system components.

INTRODUCTION
Wharfedale Pro Focus Series loudspeakers are the result of many years of experience in the use, design andmanufacture of professional loudspeaker products. We take great pride in engineering and building every Wharfedale Pro
loudspeaker and would like to thank you for entrusting us with your sound solutions.

FOCUS SERIES OVERVIEWMusic to the masses
With the Wharfedale Pro Focus point-source array system you now have a solution that provides not just exceptional
quality sound but also a flexible cabinet and hardware configuration enabling you to meet the requirements of a wide
variety of venues. Focus’ easy adaptability makes it perfect for portable rentals, touring and stage shows.

Optimised acoustic engineering
The Focus family has 4 components to choose from - a 12” and 15” PA and a 18” and twin 18” subwoofer. Focus tops
and subs are superbly engineered to work together seamlessly and provide maximum efficiency. The two-way PA
speakers employ a High-Q 100° x 10° long-throw waveguide horn geometry to project the sound au the way to the backof large listening areas. All this comes together to create a point-source array system!

Meets your needs
Focus hardware allows you to fly in a line-array configuration, fly independently and in pairs or stack PA’s on top of subs.
Focus adapts perfectly to whatever challenges your venue presents you with!

Sonic Impact
At peak output a single Focus-15 can pump out 135db SPL; maximum power handling is rated at 2800 watts peak.
Focus subs put out an equally impressive 146dB peak SPL of pounding bass with a maximum power handling capacityof 8000 watts peak. Need more? Just double up! The Focus V-Tech side-by-side driver placement maximizes mutual
coupling and boundary-effect reinforcement to move massive amounts of air and push the beat to the soul of youraudience.
