Introduction

English Introduction

Dear Music Lover,

Thank you for your decision to acquire Dynaudio Sapphire loudspeaker.

The Sapphire features the advanced Dynaudio loudspeaker technology, resulting in

music reproduction at a very high level, making many familiar recordings a new listening

experience altogether. This advanced technology results from many years of intense

research and development, the highest quality standards in production, and Dynaudio's

enduring passion for musical truth.

Dynaudio is one of very few companies who can realize such loudspeaker concepts

through it's own in-house development and production facilities. These facilities are so

advanced and the quality control is so strict that Dynaudio is likely the only specialty audio

company to have exceeded ISO 9000 and earned QS 9000 certification.

Each Sapphire loudspeaker is constructed by Dynaudio's master craftsmen in Denmark

to these high standards of quality. To realize the highest sound quality from the Sapphire,

some areas should be addressed, as will be explored on the following pages. By

considering the tips and suggestions, you will achieve the maximum performance and

enjoyment of your Sapphire loudspeaker and it's advanced musical capabilities for a long

time to come.

We wish you many years of enjoyment experiencing music,

Connecting

Connecting the loudspeakers

1. Connect a two-pole (+/-) loudspeaker cable to the binding posts, located at rear of the

cabinet (see Fig. 1). The high quality, gold plated binding posts can accommodate

different connection systems:

–4.0 mm banana plugs: The pins can be put directly into the binding post without

any tightening necessary.

–Cable spades: Untighten the binding posts, insert the spade into the opening, and

secure the spade by tightening the posts.

–Bare wires: Untighten the binding posts and place the cable into the binding posts.

Tighten the posts.

Connecting

Note

• With every connection system, ensure that the contact is tight and has a proper

contact area.

• Connectors with similar gold plating as the Sapphire binding posts will typically offer

the best results and remain corrosion-free.

• Please ensure that the positive and negative cables do not make contact with each other.

• Tighten the posts, and check the contact after a few days to make sure that it has not

loosened.

2. Connect the other cable ends to the loudspeaker outputs of your switched off power

amp (see Fig. 2).

Note

Pay attention to the correct polarity of both loudspeakers. With most loudspeaker cables

one of the two veins is characterized for better distinction:

XConnect the red marked post of the speaker to the red marked output of the amp (+),

and the white or black marked post to the white or black marked output (–) accordingly.

Bi-wiring/bi-amping

Dynaudio loudspeakers feature a carefully fine-tuned cross-over, optimized using

selected parts and an advanced circuitry to achieve a truly balanced and smooth

frequency response. Therefore, dividing the frequency sections through bi-wiring or

bi-amping is neither beneficial nor optional.

Choice of loudspeaker cable

The impact a loudspeaker cable can have on sound quality may be dramatic, though in

general quality cable products will yield a quality result.

Dynaudio loudspeakers are designed to be very neutral and thus are not extremely suited

to any particular type of cable. The choice of cable is as much a factor of matching the

cable to the entire audio system. Please consult your Dynaudio dealer for information

about compatible loudspeaker cables that will suit both your electronics and the Sapphire

loudspeaker.

Positioning

The Sapphire consists of classic bass reflex loudspeaker design with no unusual or

extraordinary positioning demands. Every room will still have its own particular sound

characteristics. Any room is also shaped and decorated uniquely, and therefore remains

independent regarding options for positioning loudspeakers. The following steps are

general suggestions that will make the correct positioning easier to achieve.

Following explanations refer to Fig. 3:

• The distance between each loudspeaker and your listening position should be the

same (B). Try to achieve an isosceles triangle.

• The distance between the loudspeakers should be the same or better slightly less

than the distance between each loudspeakers and your listening position (A, B).

• The closer the listening position is in relation to the loudspeakers, the closer the

speakers can be positioned to each other

• As a starting point, it is recommended that the speakers be about 2 meters apart from

each other for the best results (A).

• If the speakers are positioned too close to each other, the stereo image will not seem

realistic; if that distance is too wide, the image may leave an acoustic hole in the

middle.

• Paying attention to the image during listening tests will help dictate optimum

placement during experimentation and set-up.

CAUTION Excessive brightness

Direct sunlight or excessive brightness can affect the color of any natural wood veneer

(the structural integrity of the cabinet will not be affected).

XTo maintain the aesthetic quality of the Sapphire for the long term, placing such in very

warm, very cold or very humid environments should be avoided.

Positioning

Spikes and damping feet

The Sapphire floor standing speaker is equipped with a special base plate optimized for

mechanical and acoustical properties. The included floor spikes or damping feet may

either be effectively used when setting up the Sapphire.

Using spikes

Spikes ensure a very solid placement and are suitable for use on carpeted or any solid

surface floors. A total of four spikes per loudspeaker are included, each adjustable in

height, thus enabling a solid and level base on any floor, including uneven surfaces.

Mounting the spikes:

1. Screw in the spikes (four per loudspeaker) to half of the thread depth and tighten

each with the enclosed locking nuts.

2. When the loudspeaker is positioned properly (see following sections), adjust the

spikes for a solid placement if needed:

a. Untighten the locking nut of the spike you want to adjust.

b. Adjust the spike for a solid placement.

c. Tighten the locking nut again.

CAUTION Spikes with sharp peaks

The sharp peaks of the spikes may cause injuries and damage sensitive surfaces like

hardwood flooring or tile.

XBe careful when handling the loudspeakers.

XPlace plates between the spikes and the surface to protect the underlying surface.

(Note: The spike will not destroy a carpet surface.)

Positioning

Using damping feet

The damping feet are suitable for hardwood, tile and multilayered floors. The damping

properties of the material reduce vibrations which can propagate through the floor. The

four damping feet included per loudspeaker should be affixed securely, and will balance

any slight surface unevenness without scratching the floor.

Mounting the damping feet:

1. Bring loudspeaker to its assumed position and place it carefully on its back.

2. Screw in the damping feet (four per loudspeaker) using a hexagon socket screw

wrench and tighten each properly.

Distance to back and side walls

Every loudspeaker not only disperses sound energy directly into the room, but also to the

side and even backwards. As a result, time-delayed reflections occur and add to the

original music signal. Thus, when loudspeakers are positioned too close to walls, the

sound quality can be restricted.

The Sapphire loudspeaker was developed to be placed free-standing, and therefore it

reaches its optimum performance when positioned as clear of any walls as possible.

XTo reduce possible influences from the back and sidewalls, the distance to these

boundaries should ideally not be less than 0.5 meter.

Adapting the bass reflex port

To minimize low frequency reflections, which will be heard as a thickening of the sound,

the loudspeakers can be adapted to the room’s acoustic character by using foam plugs in

the bass reflex port. This will essentially attenuate the room-induced boost in the low

frequency range by dampening the deep frequencies, yielding a more clear and tight

sound and minimized backwave reflections when the loudspeaker is positioned near rear

walls.

XFully insert the foam port plugs packed with your loudspeaker into the bass reflex tube,

to attenuate the bass output (if required).

Positioning

Loudspeaker toe-in

Depending on your personal listening environment and room dimensions, the

loudspeakers may be angled in towards the listening area to focus the sound radiation.

This positioning will typically improve imaging and is especially recommended by

Dynaudio (see Fig. 7). Nevertheless will the precise positioning be left to your personal

listening habits.

Room and furniture influence

The sound quality of any loudspeaker is influenced by the furniture, wall materials and

other objects in the listening room. For example, large rooms without much furniture and

many clean, hard wall surfaces can give a bright and diffuse sound with diverse echoing

frequencies. A room with thick carpet, curtains and soft furniture surfaces will give a

slightly warmer, darker and less lively sound.

Grille

A cloth grille is included and can be affixed to the cabinet to help protect the drivers from

dust and any other influences. The grille is acoustically optimized, but the highest sound

quality levels will be attained without any grille covers in place during listening.

XTo remove the grille, gently pull the grille at all corners straight away from the front.

XTo fit the grille, line up the studs with the corresponding front baffle holes and gently

push the grille in at all corners.
