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 • MOUNTINGThe 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
REGULATIONS, CONSULT QUALIFIED PERSONNEL FOR ADVICE AND ASSISTANCE.
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.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 except that mentioned in this manual.
9.WARRANTY - In the event of malfunction, contact your authorised Wharfedale Professional dealer or distributor for further information. The SI Series from Wharfedale Professional is warranted against manufacturing defects and/or materials for a period of three years from the original date of purchase. During that period Wharfedale Professional will at its discretion repair or replace product provided that the product itself is returned with notice to an authorised Wharfedale dealer. Wharfedale Professional will not be held responsible for any defects(or any consequential damage) resulting from modifications made by unauthorised service agents, Acts of God, improper use of the equipment or negligence on the part of the user.
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
4.Power up amplifier with levels on zero. Confirm units are operating.
