First of all, thank you for deciding on quadral loudspeakers.

It is to satisfy the high expectations of music lovers and connoisseurs

such as you that we build loudspeakers of a class that is well above

average. Even though you may already be familiar with them, we list

below a few ground rules that will enable you to make optimal use of

your loudspeakers.

Safety advice for passive loudspeakers

Please take time to read through the manual carefully and follow all the steps describing

how to set up and operate the loudspeakers. Keep the manual somewhere you can

quickly access it should you have any questions later on.

• The stability of loudspeakers (especially large units) depends on the nature of the

surface on which they stand. Carpets are often very poor for stability. Even an

average bump can cause a loudspeaker to fall over and be a hazard for persons

or pets in the vicinity. Stability can be significantly improved by using “spikes”, but

care should be taken during assembly as the sharp points can cause injury and the

spikes can damage the floor. On smooth floors, the loudspeakers can be stabilised

with Velcro or double-sided tape. Loudspeakers should never be used as a seat or as

a substitute for a ladder!

• Use only wheeled furniture, stands or wall mounting systems and other devices for

attaching and installing the products, which are available from the manufacturer and

are sold for or with the product. To avoid damage or injury through tipping over,

please be careful when moving table devices or stands on which the speakers are

mounted. If wall-mounting the product, take special care that all components are

securely screwed! Additional securing equipment (chains, etc.) should be fitted.

• The location for the loudspeakers should be dry and not too cold. Constant high

humidity or strong sunlight (UV radiation) can cause your loudspeakers to age

prematurely and consequently affect their functioning.

• Very high volume levels for long periods of time are not only annoying for your

neighbours, but can also be harmful to the health of the user!

• When loudspeakers are overloaded with very high volume levels, there is a risk

of individual components in crossover circuits or individual speakers burning out.

In particularly bad cases, it is even possible for fire to break out inside a speaker.

Speakers operated at these extremes should therefore not be left unattended.

• At high volumes, voltage levels of 30–50 V can be present at speaker terminals and

components. Be very careful not to touch uninsulated terminal contacts of speakers

Setting up

To obtain optimal sound results, it is generally necessary to try out different set-ups.

Since the room conditions have a major effect on sound reproduction, we suggest below

a few useful approaches for positioning your quadral loudspeakers.

Main speakers (front)

Where the speakers are positioned in the listening space has a decisive effect on their

sound. Placing the speakers near the corners of the room will essentially give you loud

bass reproduction but with little outline. On the other hand, speakers positioned well

away from the walls sound precise, but also very bright and thin. The best solution is to

place the speakers with at least 30 cm between their backs and the nearest wall. To avoid

loud wall reflections, the distance from the side walls of the room can even be 50 cm or

more. Bookshelf speaker units sound best on a speaker stand or shelf, with the tweeters

arranged at ear height. The cases should be angled and slightly tilted to achieve this.

Ss far as possible, the speakers should be equidistant from the listening position, while

the distance of the speakers from each other can be rather less than the distance from

the listener.

Front centre speaker

Due to the proliferation of plasma and

LCD TVs, these speakers are no longer

shielded magnetically. This causes colour

and geometrical errors and can occur

on older TVs with picture tubes. Since

it can’t be placed on the TV set, the

center speaker can be set lying down

underneath it. The speaker should be at

least 30 cm from the television, and a

minimum of 20 cm from the floor. Apart

from the above, we recommend angling

the center speaker so that the tweeter is

aimed at the listener in order to enjoy its

full sound potential.

when in operation. To avoid injury, never put hands or arms into sound outlets (bass

reflex tubes). Children and pets, in particular, are at risk from this.

• For safety reasons, we generally forbid the opening of loudspeaker cabinets when in

operation or connected since, as explained in the above paragraph, voltages of up

to 50 volts can be present inside.

• Improper handling of mains voltage can cause fatal injury!

Passive loudspeakers must on no account be connected to the electricity supply!

Speaker terminals may only be connected to the appropriate output terminals of

the amplifier. You should never connect these terminals to the electricity supply

(230 V/115 V) in any way since that will otherwise also immediately destroy the

loudspeaker and all connected products. Avoid fitting plugs to ends of speaker cables

that could even remotely be confused with mains supply plugs.

• Loudspeakers that are not magnetically shielded can affect the colour of the TV picture

or cause distortion. A distance of 50 cm is generally sufficient to avoid problems of

this kind. Avoid placing items such as credit cards, diskettes, audio or video cassettes

or other magnetic media on the loudspeaker. This could destroy the information stored

on them. Similarly, avoid operating magnetic tape devices in the immediate vicinity.
