Unpacking
All Wharfedale Pro products are fully checked
before leaving the factory. After unpacking
please inspect cabinets for any physical
damage. Please retain the shipping carton if
possible and internal packing material in case the unit needs to be returned.
Please check as soon as possible the unit is functioning. In the event of any
damage please contact your dealer immediately so that a written claim for
damages can be made.
Operating/Use
1. The SI Series accept cables with Speakon™ and bare wire and
feature two Speakon™ type connectors and a barrier strip
situated at the rear of each cabinet. These are connected in
parallel. Take care to avoid adding too many SI
speaker systems in series (this does not apply to 64T). Each
series 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 8 Ω loudspeakers in
series make a 4Ω total load. Four 8Ω series connected
loudspeakers make a total load of 2Ω, which is too low for many
amplifiers.
2. Attach the speaker cable securely to your SI Series unit
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 SI Series Cabinet. Use 2
core 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 the barrier strip ensure the correct phase
connection and secure with a Pozi-drive™/flat head screw driver.
4. Power up amplifier with levels on zero. Confirm units are operating.
ƽ WARNING & SAFETY INSTRUCTIONS
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.

The SI Series enclosures are fitted with M8 size threaded
inserts. Use M8 bolts only in these inserts to suspend the
enclosure. Make sure that you use forged shoulder eyebolts
with a length of at least 30mm. Insert a flat washer between
the eyebolt and the enclosure.
7.
Ꮧ 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.
