Authorised QUAD Service Centres in the U.K. and North America www.quad-hifi.co.uk SPECIFICATIONS Quad loudspeakers are compatible with most 4 and 8 Ohm amplifiers For information on authorised service centres worldwide contact QUAD Electroacoustics Ltd.. A worldwide distributor list is available on the QUAD website: INTRODUCTION QUAD monitor loudspeakers are true to the classic QUAD tradition of clear, uncoloured sound. No compromise has been made in quality of materials or workmanship. Although we naturally recommend that these speakers are partnered with QUAD amplification, they will enhance any quality sound system. Please read the following notes carefully. They will help you to install your loudspeakers correctly and safely. UNPACKING THE EQUIPMENT Unpack the loudspeakers carefully. Be especially careful not to damage the loudspeaker cabinets when removing the polythene sleeves. Please retain the packing materials for future transportation. Retain the user manual and the information concerning the date and place of purchase of this equipment for future reference. !Switch off the amplifier and all sources before making connections to your sound system. When you switch on the system or change sources, set the volume control to minimum and turn up the level gradually. !The position of your Volume Control is NOT a reliable guide as to the maximum capabilities of your sound system. Playing the system with extreme settings of volume and tone controls may damage the amplifier and loudspeakers. !Do not connect loudspeaker terminals to the mains supply. !Ensure that your loudspeakers are correctly wired and are in phase. !Do not subject your loudspeakers to excessive cold, heat or sunlight. !WARNING: To reduce the risk of fire or electrical shock do not expose this product to rain or moisture. The product must not be exposed to dripping and splashing and no object filled with liquids - such as a vase of flowers - should be placed on the product. !No naked flame sources - such as candles - must be placed on the product. !Do not place heavy objects on top of loudspeaker cabinets. If you play them with the grilles removed be careful to protect the drive units from children and pets. !Do not use makeshift stands. Always fit a manufacturer's approved stand using the instructions and the fixings provided. Your dealer will advise you. !Do not attempt to dismantle the loudspeaker. There are no user serviceable parts inside and you will invalidate the warranty. !Site your loudspeakers at least 0.5m away from TV sets and magnetic storage media. Quad 21L and 22L: These models are floor standing and should be fitted with spikes for better stability and performance. Fitting Spikes: Carefully invert the loudspeaker. Take care to protect the top surface from scratches or damage when the loudspeaker is in the inverted position. Each speaker is supplied with a set of four spike assemblies. Screw a spike into each of the pre-drilled holes in the bottom of each loudspeaker cabinet. Return the loudspeaker to its normal position taking care not to cause damage with the spikes. Adjust the spikes so that the speakers are stable. The top surfaces should be level and the same height above the floor. When moving speakers, be particularly careful not to let the spikes pierce objects or cables which may be concealed under the carpet. Never drag the loudspeakers. If you cannot lift them easily, get someone to assist you. Quad 11L and 12L: These loudspeakers should ideally be stand mounted though they may be wall mounted or placed on a rigid shelf separate from the rest of the system.1411L, 12L, 21L, 22L Monitor LoudspeakersUSA IAG America, Inc. 15 Walpole Park South Walpole MA 02081 Tel: +1 508 850 3950U.K. QUAD Electroacoustics Ltd.

32CONNECTING THE LOUDSPEAKERS Bi-Wiring . GETTING THE BEST FROM YOUR LOUDSPEAKERS Most of the audio signal going to the speakers drives the bass units. Where one cable feeds both bass and treble units, this heavy bass current can modulate the high frequencies. Using separate cables for treble and bass units reduces intermodulation effects and improves headroom and clarity. This technique of wiring is known as Bi-Wiring. To bi-wire, you will need to install two lengths of twin core cable between the amplifier and each loudspeaker. Unscrew each terminal a few turns and remove the metal straps. The upper pair of terminals on the crossover panel feeds the treble units and the lower terminals feed the bass unit. Connect the cables between the amplifier and the loudspeakers as indicated above and re- tighten all the terminals securely. Where feasible, we strongly advocate bi-wiring. Bi-Amplifying (Bi-Amping) By connecting each loudspeaker drive unit to its own dedicated amplifier the advantages of Bi-Wiring can be extended. If you own two identical stereo power amplifiers, you may wish to try bi-amping your QUAD loudspeakers. For further details please consult your dealer Phase If the sound lacks definition or the bass is indistinct, this could be because you have inadvertently mis-connected your loudspeakers. Please check the wiring to both loudspeakers carefully, especially if they are bi-wired. Ancillary Equipment QUAD loudspeakers are compatible with the great majority of audio-visual and high fidelity equipment - but a loudspeaker is only as good as the signal it gets. Your amplifier should have ample reserves of power - a low powered amplifier can run out of steam quite easily and the resulting distortion is unpleasant to listen to and could damage your speakers. A larger amplifier will usually sound better and enhance the reliability and performance of your loudspeakers. Running In Loudspeakers are electro-mechanical and, like all mechanical systems, they need a 'running in' period. For the first 50 hours or so exercise care and play your system at reasonable volume levels. After running in, you will notice a significant sonic improvement. Care and Maintenance Little maintenance is required. The cabinets can be occasionally wiped with a damp (not wet) cloth. Spray polish, if used, should be applied sparingly - spray the polish onto a cloth and then apply it to the speaker. NEVER spray the grille cloth or the speaker drive units. To clean the grilles, remove them first before gently brushing with a soft brush. Never use solvent cleaners, minor stains are best removed with soap and lukewarm water. Avoid touching the drive units as they can easily be damaged.HFLF QUADELECTROACOUSTICSLTD. andEngineered byDesigned R OUTPUT R OUTPUT L OUTPUT L OUTPUT HF QUADELECTROACOUSTICSLTD. andEngineered byDesignedRight SpeakerLeft Speaker LFPOSITIONING YOUR LOUDSPEAKERS CONNECTIONS AND TERMINALS Crossover Network Quad crossover networks separate the treble and bass networks into two distinct sections, each connected by a dedicated pair of terminal posts. This enables the treble and bass components to be separately driven for optimum performance. The upper pair of terminals is connected to the treble network and the lower pair to the bass network. As supplied, the treble terminal pair is connected to the bass terminal pair by removable metal straps. These should be left in place for standard installations. Choosing and Preparing Cable CONNECTING THE LOUDSPEAKERS Standard Connections We recommend that the loudspeakers are placed between two and three metres apart and equidistant from the listening position. The tweeters should be roughly at ear level to a seated listener. The loudspeakers should be positioned so that they are angled slightly inward, facing the listener. The most uncoloured sound will be obtained when the loudspeakers are at least 200mm from the rear walls and 300mm from the side walls. If the loudspeakers are operated closer to the rear walls the bass extension will increase but if they are placed too close to the walls the bass may boom and become indistinct. If the loudspeakers are placed further away from the walls, the inward angle may be increased by up to 40%, although this may restrict the width of the optimum listening position. As personal taste plays a large role, please experiment with different configurations and play a wide range of music before finalising the position of your loudspeakers. Specialist audio cable will usually offer better performance than general purpose 'bell' or 'zip' wire. Audio cable is polarised, with two cores of different colours, or often, in the case of twin cable, a coloured tracer or ridge along one wire to indicate polarity. Choose a cable of suitable diameter - cable that is too thin will limit the dynamics of the sound and may impair the bass response. Split the twin cores to a depth of about 40mm. Carefully strip the insulation from each end, leaving about 10mm of bare wire. If the cable is stranded, lightly twist to gather any loose strands. Connecting Speaker Terminals Unscrew the terminal. Thread the bared end of each cable through the hole in the bottom of the terminal post. Ensure that there are no loose strands which may touch adjacent terminals. Retighten the terminal securely. Choose a suitable length of twin core speaker cable for each channel, and prepare the ends as described above. Connect the positive(+) terminal of the Left loudspeaker to the corresponding positive(+) amplifier terminal. Connect the negative(-) terminals similarly. Repeat this procedure for the Right Channel. Note that the positive(+) terminals are located on the right.
