INTRODUCTION
Congratulaons on the purchase of your new AVID Reference Four
loudspeakers. We are sure that with care they will provide you with years of
unrivalled musical enjoyment.
As with all AVID products, these loudspeakers are the result of many hundreds
of hours of development and tesng to ensure that they exceed the
performance we know our customers expect from AVID.
Please read these instrucons fully before aempng to setup and use the
loudspeakers—failure to do so may result in damage or possibly injury
SAFETY
Although compact, these loudspeakers are extremely heavy and it is highly
recommended that a minimum of two people are needed to assemble and
posion the Reference Four loudspeakers.
As with all loudspeakers, the exposed drive units are suscepble to damage if
touched.
GETTING STARTED
If you have chosen to use a third-party loudspeaker support, please ensure that
they are capable of supporng the weight of the Reference Fours, also ensure
that they are suciently stable, so there is no risk of them being knocked over.
If you purchased the matching AVID stands, a simple assembly procedure is
required (see “Assembling stand”) - again, take care, as parts involved are
heavy and can easily be damaged or cause injury—please take care to avoid
scratching any of the cosmec surfaces.

PLACEMENT RECOMMENDATIONS
Like any loudspeaker the Reference Four is aected to a great extent by the
listening environment. The Reference Four is quite easy to accommodate, but
following some simple guidelines will help:
• Posion the loudspeakers symmetrically in the room (e.g. equal distance
from either side wall). Where possible avoid asymmetrical rooms (e.g.”L”
shaped or rooms with a single alcove
to one side) - any asymmetry will
result in an imbalance of the stereo
image, and an uneven frequency
response.
• Don’t place the loudspeakers too far
apart—the distance between the two
speakers should be slightly less than
the distance from them to the
listening point—again, experimentaon is required. If the sound is lacking
bass, and the centre image is vague, try placing the speakers closer
together, conversely, if the sound is bass heavy, move the speakers further
apart, and away from the rear walls
• Twist the two speakers so that they are poinng slightly toward, but not
directly at, the listening posion—this should produce a nice sharp stereo
image, but create enough spread for several people to enjoy the
performance
• Posioning the loudspeakers close to the wall immediately behind them
will increase bass output, but at the expense of clarity and stereo image —
experiment to nd out the best compromise for you, but start at around
45cm (18”), and adjust unl you are happy with the sound
• Try to avoid locang the listening posion such that your head is too close
to the wall behind you—if this is unavoidable, try to ensure there are some
so furnishings or heavy curtains between you and the wall.

CONNECTING UP
The Reference Four uses a single pair of connectors that should be connected
back to your amplier/receiver. Always ensure that the ‘+’ terminal on the
loudspeaker connects to the ‘+’ terminal on the amplier, and likewise, the ‘-’
terminal connects to the ‘-’ terminal on the amplier. Connecng the speakers
incorrectly could result in the loudspeakers being connected “out of phase” -
this normally results in negligible bass response, and a poor stereo image.
SYSTEM MATCHING
The Reference Four is a benign load, and most ampliers will be able to drive
them without diculty. High quality ampliers of 40W per channel or more
should be more than capable of aaining sensible sound levels in a typical
listening room—however there are real benets to be enjoyed by using quality
ampliers with even greater power. Don’t be too concerned about matching
amplier power to speaker power, in fact, damage is far more likely to occur
when using an underpowered amplier than a supposedly overpowered
amplier (though care is sll needed in extreme cases).

OPTOMISING SOUND QUALITY
The ulmate sound quality of your sound system relies on a host of variables,
though there are some key points that you should take in to consideraon
• Ensure that all your audio equipment is securely posioned—not just the
loudspeakers. A good quality equipment rack can dramacally impact on
the performance of your complete system.
• Make sure there is a mix of hard and so furnishings in your listening
room—to much so furniture can result in a dull, “closed-in” sound,
whereas hard furnishings tend to create a very lively sound, which can
sound harsh and also suer from echoes.
• Try to remove any unnecessary electrical equipment out of the room– if
powered on, they can create electrical noise that will impact on your Hi-Fi
system, and in the case of televisions, the large at screen panel causes
reecons disrupng the stereo image.
• Use good quality interconnect and loudspeaker cable. With regard to
loudspeaker cable, there are large currents owing between the amplier
and speaker, so long lengths of cable should be avoided, as resistance
increases directly with length. Having stated this, it is important that both
le and right channels are both of the same length, even if one
loudspeaker is nearer to the amplier than the other.
LOOKING AFTER YOUR LOUDSPEAKERS
The only cleaning required should be a light dust with a lint-free cloth - no
harsh cleaning uids should be used. DO NOT touch the high frequency dome
as this is extremely fragile, and any creases will aect the overall sound quality.
The Low frequency driver can be gently dusted if necessary, but again, care is
required.
Be careful when using heavy speaker cable—this can put a heavy load on the
terminals, which could ulmately break—avoid sudden shocks, such as allowing
the cables to be pulled, or tripped over.

STAND ASSEMBLY
Please follow the following steps closely to minimise the risk of
damage to the product and ensuring that the stand and speaker are
securely mounted.
The stand makes use of the plinth aached to the boom of the
speaker. This plinth must be removed from the speaker rst.
Find create a space on the oor and cover it with some so material
to protect the cabinet nish.
Carefully remove the loudspeaker
from the carton, and place it on its
top on the protecve blanket, so that
the boom of the plinth is accessible.
Using the supplied 4mm Allen key,
remove the six M6 bolts (DO NOT
remove the single bolt near the
centre of the plinth—highlighted in
green here). Store the bolts safely, as
you will need them later!
Carefully li the plinth. Leave the
anodised legs where they are, but if
any have moved, make sure they are
returned to their correct recessed
locaon on the boom of the
speaker.
9
Using the supplied 25mm
countersink bolts (D), aach the two
pillars (B) to the base of the speaker
stand (A).
Locate the spikes (E), and screw them
into place on the plinth using the
supplied lock nuts to secure them in
place—ensure all four spikes are set
to the same level.
Now place the stand so that it is
resng on the oor, on its spikes
10
Take the plinth you previously
removed from the loudspeaker
and bolt it to the top of the pillars
(ensuring that the anodised
deector is poinng upwards),
using the four 15mm M6 bolts (C)
supplied. Ensure they are done
up ghtly—there should be no
movement between the plate
and the pillars.
Note the posion of the anodised
deector (shown in green)—this
denes the rear of the stand
when aaching the speaker (it
will align with the port on the
boom of the loudspeaker
cabinet). Failure to ensure this
will result in damaging both the
deector and the boom of the
loudspeaker cabinet—please take
care!
11
Aaching the stand to the loudspeaker is most
easily done by turning the stand upside down,
and carefully lowering it onto the boom of the
loudspeaker. Ensure that the anodised legs
locate fully into the shallow recesses in the top
of the stand.
It is highly recommended that at least two
people carry out this step
Once the stand is correctly located, aach the
stand securely using the six 40mm M6 bolts
removed in step 1.
IMPORTANT Ensure all six of these bolts are
secure before moving onto the next stage.
Once all the screws are in place, the whole assembly can be
carefully rolled over to its correct vercal orientaon, and placed in
its nal posion. Place some so material under the loudspeaker
during this procedure to avoid damaging the nish. Please take care,
