Important safety information The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

EMC/EMI This equipment has been tested and found to comply with the limits for a Class B Digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in residential installations. This equipment generates, uses and can radiate radio frequency energy and, if not in- stalled and used in accordance with the instructions, may cause harmful interference to radio communications.
Product Overview The transducers of your Dynaudio LYD speaker will achieve better sound quality after breaking in. Especially after the first hours of use, you may notice a significant advance in sound quality, and further subtle improvements in subsequent hours of use.

Connecting the Speakers Mains Ensure that you have the correct mains cable for your region. The power supplies in the loudspeaker have switching inputs that automatically detect the incoming voltage and will adjust to either 120V or 220V, depending on your location. Plug in the provided AC cable to the loudspeaker and then to the outlet.
If you are using a professional interface with a max output of +20dBu or more, then a setting of -6dB on the loudspeaker is the most appropriate. If you are using equipment that runs at a consumer or domestic output level (-10dBV nominal), then the +6dB setting is better. LYD User manual...
DSP Settings Dynaudio engineers have painstakingly created a DSP controller for these speakers that lets you tailor the sound to your particular environment. The DSP settings provide precision adjustments that optimize the speakers for the listening space. Bass Extension Low frequencies take an exponentially larger amount of energy to reproduce than high frequencies. That is why the bass extension setting affects how loud the speaker will respond.
▪ Pink Noise Source Dynaudio has created an iOS app with these tools built in so you can quickly test and calibrate your LYD speakers using your iPhone, iPad or iPod touch. In the Apple App Store, search for “Dynaudio Meter” to locate and download this free app.
Final Tweaks Beyond the settings for the loudspeakers, additional tweaks may be desired to improve the response of the system and room environment. You may discover that a reflective surface is causing a high frequency anomaly or perhaps room modes are disturbing the bass response in the room. First Reflection Treatment Sound reflecting off of hard surfaces that are close to the listening position can cause problems in the high frequency response and imaging of the loudspeakers.
