Positioning

Dynaudio Focus 110 A 5

Positioning

Note: Be aware that proper air circulation around the monitor for

sufficient cooling is necessary. Also notice that the heat sink is

designed to provide maximum cooling when the monitor is

positioned vertically.

Using a loudspeaker stand:

Optimum performance will be achieved when the Focus 110 A is placed

on a dedicated loudspeaker stand. The specially developed Dynaudio

Stand1allows best mechanical fixation and positions the speaker

systems at the proper height while absorbing any resonance. Please

consult your Dynaudio dealer for further informations.

Positioning without using a stand:

Due to its dimensions, the speaker may also be placed on a ledge or

shelf or on top of furniture. However, a certain loss of sound quality

cannot be avoided in these cases. The integrated sound control

switches will be helpful to minimize the acoustical disadvantages of

these positioning options. In any case please make sure to utilize a

stable surface offering a wide space in front of the speakers.

Using the 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.

To fit the grille:

XLine up the posts with the corresponding front baffle receptacles

and gently push the grille in at all corners.

To remove the grille:

XGently pull the grille at all corners straight away from the front.

Connecting

NOTICE: Avoid hot plugging the equipment connected to the

monitors. Always turn off the speaker and other equipment

when plugging or unplugging signals.

Connecting the speakers to the source

As an active speaker the Focus 110 A is equipped with internal power

amplifiers and must only be connected to a NF signal source

(e.g. Preamplifier, surround decoder, PC sound board,...).

1. Make sure the speakers are switched off.

2. From the right Pre Out of your preamplifier resp. the right Line Out

of your source connect a mono RCA cable to the Input of the right

speaker.

3. From the left Pre Out of your preamplifier resp. the left Line Out of

your source connect a mono RCA cable to the Input of the left

speaker.

Note: Use high quality cables only. This will improve the sound quality

and help the Focus 110 A speakers to realize their full potential.

Connecting a subwoofer

The Focus 110 A may be combined with a Dynaudio subwoofer such

as the Sub 250 for extended bass performance and a higher sound

pressure level if the high pass filter is used (see “Cutting off low

frequencies” on page 6).

For information about connecting the Focus 110 A speakers in

combination with a subwoofer please refer to the subwoofer operating

manual.

Switching on and setting

6Dynaudio Focus 110 A

Connecting the AC power input

NOTICE: Make sure mains voltage matches your region’s mains

voltage specification (see “Technical Specifications” on

page 10).

1. Make sure the speakers are switched off.

2. Connect the AC power input to the mains socket via the power

cable delivered with your speaker.

Switching on and setting

NOTICE: Make sure all connections are made properly and the output

of the preamplifier is set to a low level.

XSwitch the Focus 110 A speakers on.

The Power LED (2) on the backplate will light green.

Protection circuits

The Focus 110 A speaker has several built in protection circuits to

reduce the risk of hazard or damage due to overloading.

The internal power amplifiers have thermal protection. This activates if

a problem should occur, and helps protect both the electronics and the

loudspeaker drivers.

There is also a thermal sensor measuring the temperature on the heat

sink (5). An electronic circuit will mute the signal when too high

temperature is reached.

There is an overload protection circuit on the tweeter to prevent burning

the tweeter driver in case of overloading. This circuit will mute the

tweeter signal if too much current is fed to the tweeter.

The woofer channel has a built in limiter that protects the woofer unit

from too much excursion. It works by reducing the gain of the circuit

when a certain threshold level is reached.

NOTICE: Avoid running the system into severe clipping. Despite the

advanced protection system, you may still be able to

damage your speakers by severe overpowering. The limiter

works over a certain range, but exceeding this level may

send a severely clipped signal to your drivers. When a

noticeable distortion occurs, please turn down the level to

your speakers.

Cutting off low frequencies

Without any filter setting, a speaker is forced to handle the full audible

range including very low frequency signals. The Focus 110 A is

designed for reproducing low frequencies down to 55 Hz very precisely

and at high sound pressure levels.

When operating the Focus 110 A together with a subwoofer (e.g. in a

home cinema setup) or to allow a higher undistorted sound pressure

level, it is recommended to cut-off low frequencies.

Lower frequencies can be cut-off by setting the

High pass

switch

Switching on and setting

Dynaudio Focus 110 A 7

To find the best setting:

1. Follow the recommendations provided in the subwoofer operating

manual when using with a subwoofer.

2. Play music with intensive low level frequencies and try to achieve a

balance between a deep sound and a precise, undistorted

reproduction.

3. Set the High pass switch to the preferred position.

Matching the input sensitivity

Several sources may work on different output levels. The Focus 110 A

can be adapted to these different output levels by setting the Level

switch (3).

To find the best setting:

1. Refer to the operating manual of your source to find the output level

of the source.

2. Play music and compare the sound level to the volume control

position:

– if sound level is too low: set Level switch to +4

– if sound level is too high: set Level switch to -10

Adjusting the frequency response

The sound quality of a speaker is influenced by various factors:

•the quality of the speaker itself

•the quality of the complete audio chain

•the acoustical environment

•the speaker position

Additionally your personal understanding of sound quality may be

different to that of others. All these factors make it necessary to have

the possibility for adjusting the sound character within a certain range.

The sound character of the Focus 110 A can be adjusted by setting the

LF, MF and HF switches.

Troubleshooting

8Dynaudio Focus 110 A

To adjust the frequency response:

1. First check the overall setup of your audio components (e.g. the

preamplifier sound controls) and the speaker position. Note that

slight changes in the speaker position could improve the sound

quality dramatically. Setting the filter switches should be your last

steps in fine tuning the sound.

2. Play music covering a wide audio frequency range.

3. Compare your sound experiences to the cases explained in Table

on page 8 and set the filter switches accordingly.

Note: Due to the numerous combination possibilities of audio

components, acoustical environment and speaker positions the

explanations can just apply to a few cases. Your own personal

listening experience will be the final benchmark.

Troubleshooting
