Dynaudio DM 1

Introduction

English Introduction

Dear Music Lover,

Thank you for your decision to acquire Dynaudio DM loudspeakers.

Every DM model 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 DM loudspeaker is constructed by the Dynaudio loudspeaker specialists in

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

DM models, 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 the DM loudspeakers and their advanced musical capabilities for a long time

to come.

We wish you many years of enjoyment experiencing music,

Dynaudio

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: Un-tighten the binding posts, insert the spade into the opening, and

secure the spade by tightening the posts.

–Bare wires: Un-tighten the binding posts and place the cable into the binding

posts. Tighten the posts.

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

proper contact area.

• Connectors with similar gold plating as the DM 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

hasn’t loosened.

Connecting

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

amp (see Fig. 2).

Note: Please make sure that the red marked post of the speaker is connected 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. One good option is the Dynaudio Ocos constant

impedance loudspeaker cable, which is also designed to be extremely neutral. Please

consult your Dynaudio dealer for information about compatible loudspeaker cables that

will suit both your electronics and the DM loudspeakers.

Connecting surround speakers

When connecting a two-channel stereo system, only the right and left channels are

connected to the amplifier. In a surround set-up, center, side or rear loudspeakers as well

as a subwoofer are typically connected to provide for a multi-channel listening experience.

Please refer to the amplifier’s owner manual for particular connection instructions and see

chapter “Multi-Channel Setup” on page 9 for further help.

Positioning

Note: To maintain the quality of the DM loudspeakers for the long term, placing such in

very warm, very cold, very humid environments and the exposure to direct

sunlight should be avoided.

The DM range consists of classic bass reflex loudspeaker designs 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.

General recommendations

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.

Positioning

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 DM models were developed to be placed free-standing, and therefore they reach

their 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 DM models 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

Compact loudspeaker set-up

The compact DM models are designed to offer exceptional performance while taking up

minimal space. The mini-monitors will realize their optimum performance when used in

conjunction with a dedicated stand (such as the Dynaudio Stand1, Stand3or Stand4) to

position them at the proper height while absorbing any resonance.

In the event a wall mount is desired, we recommend the Dynaudio WSB1– an

exceptionally sturdy wall mount bracket. It features a solid and sturdy double-jointed steel

construction which facilitates positioning the speaker within a wide range of adjustment.

The wall distance may easily be varied, while the continuously variable vertical tilt allows

a perfect orientation to the listener.

Due to its dimensions, you can also place the loudspeaker on a ledge or shelf or on top

of furniture. Here, the Dynaudio SF1loudspeaker base is ideal, optimizing loudspeaker

performance by positioning the speaker with a slight upward tilt, thus minimizing the

impact of surface reflections on the sound quality. Furthermore, the tilted speakers take

on a very attractive appearance.

In any case, it is important to utilize a stable surface offering a wide enough space in front

of the loudspeakers as to not limit the sound quality and performance. In such applications

or if placing the speakers in enclosed audio/video furniture, the bass reflex port can

usually be left unplugged as long as there is minimal clearance to the boundaries at the

top and rear of the loudspeaker cabinet, as the speakers will measure and perform as

would a front ported version due to the specific tuning of the drivers.

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. 5).

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.
