INTRODUCTION

Congratulaons 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 tesng to ensure that they exceed the

performance we know our customers expect from AVID.

Please read these instrucons fully before aempng 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

posion the Reference Four loudspeakers.

As with all loudspeakers, the exposed drive units are suscepble to damage if

touched.

GETTING STARTED

If you have chosen to use a third-party loudspeaker support, please ensure that

they are capable of supporng the weight of the Reference Fours, also ensure

that they are suciently 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 cosmec surfaces.

PLACEMENT RECOMMENDATIONS

Like any loudspeaker the Reference Four is aected to a great extent by the

listening environment. The Reference Four is quite easy to accommodate, but

following some simple guidelines will help:

• Posion 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, experimentaon 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 poinng slightly toward, but not

directly at, the listening posion—this should produce a nice sharp stereo

image, but create enough spread for several people to enjoy the

performance

• Posioning 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 unl you are happy with the sound

• Try to avoid locang the listening posion 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 amplier/receiver. Always ensure that the ‘+’ terminal on the

loudspeaker connects to the ‘+’ terminal on the amplier, and likewise, the ‘-’

terminal connects to the ‘-’ terminal on the amplier. Connecng 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 ampliers will be able to drive

them without diculty. High quality ampliers of 40W per channel or more

should be more than capable of aaining sensible sound levels in a typical

listening room—however there are real benets to be enjoyed by using quality

ampliers with even greater power. Don’t be too concerned about matching

amplier power to speaker power, in fact, damage is far more likely to occur

when using an underpowered amplier than a supposedly overpowered

amplier (though care is sll needed in extreme cases).

OPTOMISING SOUND QUALITY

The ulmate sound quality of your sound system relies on a host of variables,

though there are some key points that you should take in to consideraon

• Ensure that all your audio equipment is securely posioned—not just the

loudspeakers. A good quality equipment rack can dramacally 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 suer 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

reecons disrupng the stereo image.

• Use good quality interconnect and loudspeaker cable. With regard to

loudspeaker cable, there are large currents owing between the amplier

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 amplier 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 aect 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 ulmately break—avoid sudden shocks, such as allowing

the cables to be pulled, or tripped over.

SPEAKER STAND

The Speaker stands are supplied as an easily assembled kit.

Each stand comprising:

(A) 1 x Base

(B) 2 x Pillar

(D) 4 x 35mm countersink hex bolt (use for base to pillar)

(E) 4 x Spike/locknut combinaon

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 aached to the boom 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 protecve blanket, so that

the boom 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

locaon on the boom of the

speaker.

 Using the supplied 25mm

countersink bolts (D), aach 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

resng on the oor, on its spikes

 Take the plinth you previously

removed from the loudspeaker

and bolt it to the top of the pillars

(ensuring that the anodised

deector is poinng 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 posion of the anodised

deector (shown in green)—this

denes the rear of the stand

when aaching the speaker (it

will align with the port on the

boom of the loudspeaker

cabinet). Failure to ensure this

will result in damaging both the

deector and the boom of the

loudspeaker cabinet—please take

care!
