IMPORTANT WARNINGS & SAFETY INSTRUCTIONS
• READ ALL INSTRUCTIONS - Become familiar with the features and functions of these products before operating
them.
• COMPLY WITH ALL WARNINGS - All warnings and instructions for this product should be adhered to.
• 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 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
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.
• CABLES - Do not use shielded or microphone cable for connection between amplifiers and speakers. Use only
approved speaker cables with proper connectors.
• RIGGING, SUSPENDING, AND MOUNTING - Suspending and mounting of these 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 not properly qualified or do not know of pertinent regulations, consult qualified
personnel for advice.
• CAUTION - These professional loudspeaker systems are capable of generating very high sound pressure levels.
Use care with placement and operation to avoid exposure to exposure to excessive volume levels. Permanent
hearing damage can result when operated to extreme levels.
• SERVICE-There are no user serviceable parts inside this product. Users should not attempt to service this
product. Warranty nullification could result if this is attempted.

Wharfedale Pro SIGMA Series are extreme power handling, ultra hardwearing loudspeakers in an affordable
package built for a multitude of live sound applications. Our latest developments in loudspeaker technology
harness dual voice coil woofers reaching depths of 35Hz. These proprietary LF drivers are paired with 1.75”
Titanium Tweeters which throw high end to your crowd, while crossover points and acoustic charactaristics are
tuned by our experienced engineers for sonic accuracy. The cabinets adapt to multiple formations – M8 rigging
points, dual angle speaker poles and carry handles meet the varying demands of fixed installation and touring with
our Rhino Rock finish and steel grilles providing protection for a lifetime of use.

KEY FEATURES
Before attempting to install a SIGMA Series Loudspeaker system please refer to the important warnings and safety
instructions. Only qualified 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.
Speakers with dual angle pole mount sockets (SIGMA 10 / 12 / 15) have an sockets 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 reflections.
Please ensure that the correct socket is used for each speaker.
INSTALLATION
3
Connecting the SIGMA Series to your system is easy. The input panel includes parallel Speakon connectors. Run
your speaker wires from your amplifier to the speaker - you can use either input connector. Use the correct gauge
of stranded insulated speaker cable according to the power handling ability of your SIGMA Series cabinet. It is
always advisable to use heavier gauge (lower number) cables on longer runs. Be sure to connect your speakers in
proper polarity (what many refer to erroneously, as phase).This means that in normal operation, connect one end
of the same wire to the + or Red terminal on the amplifier and the other end to the +1 on the NL4 Connector. The
other wire is connected to the-1 pin on the NL4 CONNECTOR. Be sure to use high quality, low gauge (thick) speaker
wire and NOT shielded cable.
CONNECTIONS/WIRING
The SIGMA Series loudspeakers feature parallel wire inputs. Either input can be used for a simple system and 2
speakers can be parallel wired using a standard speaker cable. When Parallel wiring loudspeakers always take in
consideration the load you are putting on your amplifier. 2 parallel wired SIGMA loudspeakers will produce a 4
ohm load.
SIGMA SERIES CONNECTION PANELS
To avoid any possible damage to your amp and speakers, be sure to check the owner’s manual of your power
amplifier to confirm it is capable of operating at 2 ohms. The SIGMA 18B has a High Pass output. The high pass
allows you to connect a full range SIGMA loudspeaker and subwoofer to one amplifier channel with 4 ohm load

All full range SIGMA enclosures (except SIGMA-18B) include multiple M8 rigging points for fast, safe and secure
suspension.
Using Shoulder Eyebolts
Always apply the load to the bolt along the plane of the eye. For long term installation use a thread-locking
compound. Do not attempt to bend or otherwise deform any rigging hardware.
Please refer to the important safety warnings before you consider suspending any loudspeakers.
Each primary load bearing suspension point shall be rated for the total load.
