Spikes with sharp peaks
The floor-standing Focus XD loudspeakers allow for setup with spikes. The
sharp peaks of the spikes may cause injuries and damage sensitive surfaces
like hardwood flooring or tile.
- Be careful when handling the loudspeakers.
- Place plates between the spikes and the surface to protect the underlying surface.
ATTENTION
Light, heat, electromagnetic radiation
Direct sunlight or excessive brightness can affect the colour of your loudspeakers’ natural wood veneer. Built-up heat can lead to overheating. Electromagnetic radiation of different devices can lead to mutual impairment to functions.
- Avoid placing the device in very warm, cold, or humid environments.
- To maintain the aesthetic quality of your loudspeakers for the long term, placement in light-intensive, sunny environments should be avoided.
- Please ensure sufficient ventilation and observe the required distances around the loudspeakers.
- Do not place the loudspeakers near devices with strong electromagnetic radiation or devices that could be destroyed or damaged by magnetic fields.
Floor-standing loudspeaker setup
The floor-standing Focus XD loudspeaker features a special base construction, which offers both an ideal performance and mechanical basis. The spikes screwed into the end of the feet on the base can be unscrewed and their height adjusted, to adapt to uneven floors. When the spikes are retracted, the loudspeakers stand on rubber feet. These stabilize the cabinet on an extremely small contact area, and therefore prevent any wobbling while offering optimal resonance control.
The best setup variant depends on the nature of the room and the floor in particular. Your Dynaudio distributor would be happy to assist you during setup.
Compact loudspeaker setup
The compact Focus models are designed to offer exceptional performance while taking up minimal space. Due to adverse effects to the sound quality, compact loudspeakers should not be placed on the floor. The mini-monitors will realize their optimum performance when used in conjunction with a stand to position them at the proper height while absorbing any resonance. Please contact your Dynaudio distributor for more details.
Due to its dimensions, you can also place the loudspeaker on a ledge or shelf
or on top of furniture. To avoid the possibility of any negative influence on
sound quality, make sure to utilize a stable surface offering a wide enough
space in front of the loudspeakers as to not limit the sound quality and
performance.
Selecting the installation location
The Focus XD loudspeakers do not require special positioning, though the quality of the individual loudspeakers’ sound is affected by the acoustic properties of the room. Since rooms are shaped uniquely, the positioning of the loudspeakers results in totally different behavior. 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.
The following information steps are therefore general directions that will make correct positioning easier to achieve. Furthermore, we recommend taking advantage of the services provided by your Dynaudio distributor to fully exploit the sound potential of your loudspeakers in your own listening room.
**Right and left loudspeaker
**
The outside of the left and right loudspeakers is different, with a different arrangement of the display (see figure above) and labelling on the rear side.
- Position the loudspeakers in the desired location.
**Distance to 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. Focus XD loudspeakers were developed to be placed freestanding, and therefore they reach their optimum performance when positioned as clear of any walls as possible.
- To reduce possible influences from the back and sidewalls, the distance to these boundaries should ideally not be less than 0.5 meter.
- Adjust the sound of your loudspeakers (Check down below).
Distance to the listening position
- 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, preferably, slightly less than the distance between each loudspeaker 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 setup.
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. However, you are free to select the precise position based on your personal listening habits.
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. If a front grille is used, it is held on the front of the housing by means of magnets.
Grille
Removing and attaching the front grille:
- To remove the grille, gently pull the grille at all corners straight away from the front.
- To fit the grille, line it up exactly in front of the housing with the logo facing upwards and carefully push the cover onto the loudspeaker.
Connections and control elements
This section describes the connections and control elements for the
components. Please contact your Dynaudio distributor if you have any problems

Connecting the loudspeakers
- To connect the loudspeakers, switch all components off.
Connecting the digital signal source
You can connect your loudspeakers as follows:
- Both loudspeakers are connected using cables. This requires two digital cables but the systems benefits from signal processing of 24 bits/192 kHz.
- You only connect one loudspeaker using a cable; the connection between the loudspeakers is wireless. This requires one digital cable and provides signal processing capabilities of 24 bits/96 kHz.
- Both loudspeakers are operated wirelessly via a Dynaudio Hub or Connect box with signal processing of 24 bits/96kHz.
Connecting both loudspeakers with cables
- Connect the digital output for the signal source to the digital input ( Digital Audio IN ) on one loudspeaker. You can choose whether to use the right or left loudspeaker.
- Operate the connected loudspeaker as master by setting the Channel Mode switch on the rear side of the housing to Master.
- Connect the digital output on the master loudspeaker to the digital input (Digital Audio IN) on the other loudspeaker.
- Operate the loudspeaker connected in this step as slave by setting the Channel Mode switch on the rear side of the housing to Slave.
Connecting only one loudspeaker with a cable
- Connect the digital output for the signal source to the digital input (Digital Audio IN) on one loudspeaker. You can choose whether to use the right or left loudspeaker.
- Operate the connected loudspeaker as master by setting the Channel Mode switch on the rear side of the housing to Master.
- Operate the other loudspeaker as slave by setting the Channel Mode switch on the rear side of the housing to Slave.
Operating the loudspeakers via a Hub or Connect
Dynaudio’s innovative Connect system offers the option to operate the loudspeakers completely wirelessly. The connection to the loudspeakers is established by either a Dynaudio Hub or Connect box to which the analog and/ or digital sources can be connected. For more details, please refer to the Connect Owner’s Manual or learn more at http:// www.dynaudio.com/home- audio/connect/
- Install and configure the Connect system according to the Connect owner’s manual.
- On the rear side of the housing, select the red, green, or blue zone. Loudspeakers that belong to a common zone can be operated together using the remote control.
- Operate one loudspeaker as master and the other as slave by setting the respective switch (Channel Mode) correspondingly on the rear side of the housing. The assignment of master and slave is irrelevant.
Connecting the analog signal source
The loudspeakers can also output signals from an analog signal source. The signal source is connected to the analog inputs.
- Connect the left analog output from the signal source to the analog input (Analog Audio IN) on the left loudspeaker.
- Connect the right analog output from the signal source to the analog input (Analog Audio IN) on the right loudspeaker.
- Operate one loudspeaker as master and the other as slave by setting the respective switch (Channel Mode) correspondingly on the rear side of the housing. The assignment of master and slave is irrelevant.
Operating the loudspeakers without controlling the volume
You can also operate the loudspeakers without controlling the volume yourself. The amplifiers integrated into the loudspeakers function as a power amplifier; volume is controlled via the source signal (e.g. pre-amplifier).
- Connect the left analog output from the signal source to the analog input (Analog Audio IN) on the left loudspeaker.
- Connect the right analog output from the signal source to the analog input (Analog Audio IN) on the right loudspeaker.
- Set the Channel Mode switch on the back side of the housing to External.
High sound pressure levels
In the External operating mode, signals are amplified at the maximum.
Connecting a signal source with an uncontrolled or maximum level can harm your
hearing and cause damage to the components.
- Only connect controllable signal sources.
- Before switching on the loudspeakers, turn down the volume for the signal source using its volume control.
Adjusting the loudspeakers’ sound
The sound of Focus XD loudspeakers can be adjusted by increasing or lowering high and low frequencies. Each loudspeaker can be set separately and individually based on the room conditions and personal listening preferences.
Adjusting the low-frequency range
The Speaker Position rotary knob allows you to lower low frequencies. This allows you to balance out elevated or cancelled out low-frequency signal portions, as they often occur in living spaces.
- Set the Speaker Position rotary knob to the desired position on the back side of the housing for each loudspeaker. There are 2 additional intermediate stages between each of the main positions that click into place (Neutral, Wall, and Corner).
- Neutral: free-standing loudspeaker (no change to sound).
- Wall: if placed near a wall.
– Corner: if placed in a corner.
Adjusting the treble
Using the Treble switch on the rear side of the housing allows you to adjust the character of the sound to your listening preferences.
- Set the Treble switch on the rear side of the housing to one of three settings:
- +1 dB: Increase, creates a somewhat brighter sound.
- 0 dB: Neutral position, no change.
- 1 dB: Lowering, creates a somewhat warmer sound.
