IMPORTANT WARNINGS & SAFETY INSTRUCTIONS
1. READ ALL INSTRUCTIONS – carefully and become familiar with the features
and functions of these products before operating them.
2. RETAIN THESE INSTRUCTIONS – for future reference.
3. COMPLY WITH ALL WARNINGS – All warnings and instructions for this
product should be adhered to.
4. USE WITH AMPLIFIERS – In order to avoid damage to drivers and other
equipment, it is advisable to establish and follow a routine for powering up and
powering down a sound system. With all system components connected, turn
on source equipment (mixers, signal processors, record and playback units,
etc.) BEFORE powering up amplifiers. Transient voltages from powering up
source equipment can damage speakers if amplifiers are already turned on.
Make sure that amplier volumes are set to their minimum settings and power
up any system ampliers LAST. It is recommended that all system components
be allowed to stabilize for several 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.
5. CABLES – Do not use shielded or microphone cables for connection between
amplifiers and speakers. Use only approved speaker cables with proper
connectors.
6. CAUTION – These professional loudspeaker systems are capable of
generating very high sound pressure levels. Use care with placement and
operation to avoid exposure to excessive volume levels. Permanent hearing
damage can result when operated to extreme levels.
7. SERVICE – There are no user serviceable parts inside this product. Users
should not attempt to service this product. Warranty nullication could result if
this is attempted.
8. RIGGING - SUSPENDING - MOUNTING - Rigging suspending or mounting of
speaker systems can expose members of the public to serious health risks and
even death.
UNDER NO CIRCUMSTANCES ATTEMPT TO RIG, SUSPEND OR
OTHERWISE MOUNT THESE SPEAKERS UNLESS YOU ARE
FULLY QUALIFIED AND CERTIFIED TO DO SO BY RELEVANT
LOCAL, STATE AND NATIONAL AUTHORITIES. ALL RELEVANT
SAFETY REGULATIONS MUST BE FOLLOWED. IF YOU ARE

INTRODUCTION
Wharfedale Pro Delta Series loudspeakers are the result of many years of
experience in the use, design and manufacture 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.
The new Delta Series Series builds on the solid reputation of its predecessors the
LX and DLX Series, both huge successes on a global scale.
The Delta Series has been designed to deliver excellent performance, build
quality and reliability in a format that is suitable for both fixed installations and
touring applications.
High output, low distortion cast frame woofers with 3” voice coils are used in
all full-range models; 2” titanium compression drivers are coupled to 90°x45°
elliptical waveguides for smooth dispersion. All subwoofers use 4" voice coils.
Comprehensive rigging points are provided for use in own applications, so Delta
is equally at home in a wide variety of xed installation and touring applications.
Rhino Rock™, our new texturised composite finish is used in all models. This
new finish combines the great look of a painted finish with the durability of a
carpet covered enclosure, giving you the best of both worlds. In addition Rhino
Rock™ helps to reduce cabinet resonances and improve sound quality. The Delta
Series is constructed with internally braced plywood and features dual angle pole
mounts to ensure that your sound is aimed directly at the audience.
All components are designed in house and built from the ground up in
Wharfedale’s own vertically integrated factory, providing the consumer with world
class performance and unparalleled value.

INSTALLATION
• Before attempting to install a Delta Series loudspeaker system please refer to
the important warnings and safety instructions. Only qualied personnel should
install a loudspeaker system.
Improper installation of a loudspeaker system can cause serious
harm and even death if correct procedure is not followed. Anyone
attempting installation assumes all liability arising from such use.
• Bi-amp switching - ensure that the internal passive network selector is in
the correct position. When using an external active network select the bi-amp
setting. Failiure to do his can result in damage to the drivers of your Delta Series
loudspeakers.
• Models with dual angle pole mount sockets (Delta 12 and Delta 15) have an
angled socket that angles the cabinet down by 10°. This allows more sound to be
aimed directly at the audience and less at the ceiling, reducing early reections.
Please ensure that the correct socket is used for each speaker.
