Wharfedale Pro Limited Warranty*
Wharfedale Pro LIX-C Series loudspeaker systems are warranted to be
clear of manufacturing or materials defects for a period of one year from the
original date of purchase. In the event of malfunction, contact your
authorised Wharfedale Professional dealer or distributor for information.
*Be aware that warranty details may differ from country to country. Contact your dealer or

WHARFEDALE PRO LIX-C SERIES
Operating/Use
1. The LIX-C Series accept cables with Speakon™ and 1/4” jack
connectors. The units feature two jack sockets and two Speakon™
type connectors situated at the rear of each cabinet. These are
connected in parallel. You can connect The lix-c cabinets in
parallel. Take care to avoid adding too many speaker systems in
parallel. Each parallel connected speaker increases the load on the
amplifier and can add up to a total load that may exceed the
amplifier’s capabilities, leading to possible damage. Two 8Ω
loudspeakers in parallel make a 4Ω total load. Four 8Ω parallel
connected loudspeakers make a total load of 2Ω, which is too low
for many amplifiers.
2. Connect the speaker cable securely to your LIX-C cabinet and
power amplifier (the amplifier should be off, power down mode).
Where possible use Speakon™ connectors as they are
professional high current connections specifically designed for this
application. Try to use the correct type of speaker cable according
to the handling ability of your Lix-C Series Cabinet. Use 2
conductor equal stranded insulated cable for speaker runs. It is
always advisable to use heavier conductor cables on longer runs.
3. If using Speakon™, insert the speakon and rotate 1/8 of a turn
until locked in. If using a jack plug insert until secure.
4. Power up amplifier with levels on zero. Confirm units are
operating.

WARNING & SAFETY INSTRUCTIONS
Wharfedale Pro LIX-C Series of Professional Sound Reinforcement Loudspeakers
1. READ INSTRUCTIONS carefully before operating this product.
2
.
RETAIN these instructions.
3. COMPLY WITH WARNINGS - All warnings and instructions for this
product should be adhered to.
4. USE WITH AMPLIFIERS - In order to avoid damage, it is
advisable to establish and follow a pattern for turning on and off any
sound system. With all system parts connected, turn on source
equipment, tape decks, instruments, mixers, signal processors etc.,
BEFORE turning on your power amplifier. Many products output turn
on and turn off transients that can damage speakers. By turning on
your power amplifier LAST and making sure the amplifier’s input
controls are at minimum any transients “upstream” of the amplifier are
not amplified and passed to the speaker. Wait until all system parts
have stabilised, then bring up amplifier controls to operating level.
This should take no more than a few seconds. Similarly when
shutting systems down, always turn down amplifier input controls and
then turn off your amplifier BEFORE shutting down other components.
Professional amplifiers often feature delayed turn on/off circuits to
perform these functions for you automatically.
5. CABLES - Never use shielded or microphone cable for any
speaker connection as this will not be heavy enough to handle the
amplifier load and could cause damage to the complete system.
6. RIGGING • SUSPENDING • MOUNTING
The rigging, suspension or mounting of this speaker system can
expose members of the public to serious health risks and even death.
UNDER NO CIRCUMSTANCES ATTEMPT TO RIG, SUSPEND OR
OTHERWISE MOUNT THIS SYSTEM 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
AND ASSISTANCE.
7. 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 levels that
can cause permanent hearing damage.
8. SERVICING - The user should not attempt to service this product.

LIX-C FULL RANGE SERIES
LIX-C12X • LIX-C15 • LIX-C15M
FULL RANGE OPERATION: The speakers in this series are a full
range, high power handling, high efficiency cabinet designed for
demanding professional applications such as the reproduction and
reinforcement of music, musical instrument, vocal and spoken
voice. In the standard passive mode, the power amplifier can be
connected to the LIX-C full range connection.
LIX-C SUB BASS RANGE SERIES
LIX-C15SB • LIX-C18SB • LIX-C18MB
SUB WOOFER OPERATION: Where significant extension of low
frequency output of your system is required, the addition of a LIX-C
Series SUB will provide well balanced, high output enhancement
and power to the overall system. The LIX-C Sub bass units are
designed to work with an external powered x-over unit.
For high output and demanding applications the Lix subs are
powered directly and exclusively from their own amplifier. For the
recommended x-over point of the particular LIX-C Sub Bass
cabinet being used consult the specification table above under
‘EFFECTIVE X-OVER POINT’.
It is possible to operate subwoofers at higher low pass frequencies
than recommended however system sound quality and integrity are
improved by the use of lower frequencies. Thus higher output
levels can be used with human voice and instrument fundamentals
maintained at more natural balance. If you have a variable low
pass on your active crossover, we
recommend experimenting for the ideal
frequency for your application. Take care to
re-adjust relative systems levels for any
frequency changes made.
