Monitor Loudspeakers
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.
! 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 loudspeakers are compatible with most 4 and 8 Ohm amplifiers

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.
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.
