Make sure you have plenty of unobstructed working space.
Place a soft cloth on the floor to protect the loudspeaker.
Invert the loudspeaker onto the cloth.
Thread a locknut onto each spike and loosely rub it up
the thread.
Thread the spikes into the spike inserts. Tighten them
with finger tight.
Invert the loudspeaker. Be careful not to damage the
floor with the spikes.
When the speaker is upright: You will probably find
that the speaker will wobble with one spike not
contacting the floor. Adjust this spike until all four
spikes are in contact to the floor.
With the aid of a spirit level move each spike in and out
until the loudspeaker is level and sitting squarely on all
four spikes without rocking.
Now tighten each locknut securely against the collar in
the plinth to secure the spike.
Screw in rubber feet are provided for use on wood or
stone floors etc. and should be attached in the same
manner as the spikes.

INTRODUCTION
The QUAD Revela Series is a striking new speaker series from QUAD - the originators of
‘The Closest Approach To The Original Sound’.
Revela continues the QUAD innovations laid out in recent years, taking learnings from the award-winning S-series and
Z-series whilst maintaining its strong design heritage, traceable back to 1949 and the first QUAD speaker – the Corner Ribbon.
QUAD Revela brings modern design cues coupled with the now synonymous QUAD ‘True RibbonTM’ HF driver.
QUAD’s director of Acoustics, Peter Comeau, has furthered his ground-breaking engineering work in developing a new
Ribbon HF that brings a new level of musical delicacy, smoothness and hear-through performance that helps make the
music sing. The True Ribbon HF will reveal beautiful details of your music collection with a truly a breathtaking
performance.
The QUAD Revela HF is married to equally high-performance bass and midrange drivers. Using a new ‘RevealTM’
advanced fibre composition, the QUAD Revela drivers have been subject to almost 3 years of continuous innovation.
Refined and further refined for seamless integration with the Ribbon HF, the smooth diaphragm drivers were purpose
selected based upon their rigidity and excellent self-damping properties. Combined with the specially developed, custom
rubber surround for a greater excursion and high-power motor system, the result is a superb bass performance, with
power, depth, speed and articulation in abundance.
And, of course, putting it all together is a phase-compensated Acoustic Butterworth crossover that is the result not
only of Computer-Aided Design but also hundreds of hours of critical listening tests using all types and flavours of
music, in order to achieve perfection.
Each QUAD Revela cabinet is skilfully hand-finished with real-wood veneers and precision-fitted baffle seamlessly joined
with a polished finish. But more than just a truly stunning furniture quality piece of craftsmanship, the cabinet is internally
braced, using a purpose engineered structure connect to the cabinet panels in a manner that dissipates unwanted
vibrations and resonances, thus maintaining structural rigidity, even under the most strenuous of performances.
Adding to the highly effective innovations in QUAD Revela, the port tube design is precisely positioned with the optimum
diameter and flaring to prevent longitudinal resonances from colouring the speaker's performance. The low and midrange
frequencies can perform with a free-flowing purity and no unintended resonance or boominess – giving you the full
dynamics of your music.
QUAD Revela Series – advanced technology, beautiful looks and breatktaking performance combined for
‘The Closest Approach To The Original Sound’.

Stands
The bookshelf loudspeakers are intended primarily for stand mounting, though they can be mounted on wall brackets or
even on sturdy shelves. The quality of loudspeaker stands greatly influences the performance of your loudspeakers, please
do not use flimsy products.
Cables and Connectors
Choosing Loudspeaker Cable
Specialist audio cable usually offers better performance than general purpose ‘bell’ or ‘zip’ wire.
Choose a cable of suitable diameter – cable that is too thin will limit the dynamics of the sound and may impair the bass
response. Audio cable is polarised, with two cores of different colours, or often a raised rib or coloured tracer in the case
of twin cable. Before you purchase your cable, give careful thought to the positioning of your loudspeakers.
This is especially the case if you are bi-wiring your loudspeakers.
Cable lengths to loudspeaker pairs should be the same for left and right channels in order to equalise the signal
transmission. Allow some slack in your speaker cables so you can alter their position to best advantage.
Preparing Loudspeaker Cable
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 Screw Terminals
All loudspeakers use screw terminals.
Unscrew the terminal. Insert the bare end of the cable into the hole in the base of the
terminal. Tighten securely.
When connecting terminals make sure you leave no strands of bare wire that can
short across to adjacent terminals.
As an alternative to bare wire you can use specialist spade connectors. Your QUAD
dealer will be pleased to advise you on this issue.

SPECIFICATIONS INTRODUCTION

Positioning the Front Loudspeakers
The Revela 2 model is designed to be floorstanding. We suggest that they are positioned at least 200mm from the rear walls
and 700mm from the side walls, facing slightly inwards. The Revela 1 model should be stand or wall mounted though they
may be placed on a rigid shelf. The bass extension will improve if the small speakers are operated closer to the rear wall.
If the loudspeakers are placed too close to the walls the bass will increase but may be boomy and indistinct. If the
loudspeakers are placed 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.
A useful rule of thumb is that the listener should be as for from the loudspeakers as they are from each other. The speakers
should ideally be positioned so that the treble units are roughly at ear level to s seated listener. As personal taste plays a
large role, experiment with different configurations and play a wide range of programmes before finalising the position of
your speakers.

GETTING THE BEST FROM YOUR LOUDSPEAKERS
Phase
If the sound lacks definition or the bass is indistinct, this could be because you have inadvertently misconnected 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. Your amplifier
should have ample reserves of power - a low-power amplifier can run out of steam quite easily and the resulting distortion
is unpleasant to listen to and could damage your speakers. A more powerful 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 at 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.

CONNECTING THE LOUDSPEAKERS
Standard Connections
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.

Looking After Your Loudspeaker
·Your QUAD Revela loudspeakers are finished with a 'piano lacquer'. This is a multi-layer high-gloss paint finish of
the highest quality. They should not be waxed or treated with spray solvents which will smear and dim the finish.
Occasionally polish them with a dry or barely moist cloth to remove dust and finger marks etc.
·If you play the speakers with the grilles offexercise great care. We recommend that you do not operate speakers with
the grilles offif there are children or pets in the house.
·Occasionally, remove the loudspeaker grilles and brush them gently with a soft brush before replacing them carefully.
·We advise that you do not use a vacuum cleaner to clean loudspeaker grilles.
·We advise that you do not place anything on your loudspeakers to prevent damage to the cabinet surface.
·Avoid getting any liquid behind the grille. If you spill liquid on your loudspeakers, take them to your dealer for attention
before using them again.
·Do not open the speakers, there are no user serviceable parts inside.
·NEVER touch the drive units either with an object or your hands.
