First of all, thank you for deciding on AURUM 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

(W)

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

Setting up

As a rule you should try various set-up positions in order to get the best sound results. Since the positioning of loudspeakers decisively influences the quality of the sound they deliver, we’ll start by giving you some hints on how and where to set your AURUM units up.

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 a clearance of 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. As 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.

Positioning your speakers on hard floor surfaces

If your AURUM floorstanding speakers are going to be placed on a hard floor surface, for instance on tiles, stone, parquet or laminate, we urgently recommend that you fit the supplied rubber mats in place under the cabinet base. These mats will protect your speakers as well as the floor from damage while compensating any slightly uneven spots. However, you will not need to use them where soft floor surfaces such as carpets are concerned since the aluminium discs pre-fitted between the cabinet and base already serve the purposes of acoustic decoupling. When fitting the rubber mats (S) onto the speaker base you will need a helper as well as the cardboard angle strip that you will find in the speaker packaging. We recommend doing so on each of the speakers as follows:

• Firstly, determine where you definitively wish to position the speaker in the listening area and have the angle strip and rubber mat ready to hand.

• Your helper should now tilt the cabinet slightly to one side so that you can slide the angle strip one centimetre (at the most!) under the raised edge of the cabinet base.

• Your helper should now tilt the cabinet slightly to the other side and hold it in this tilted position while you fit the rubber mat precisely into place under the raised base; when doing

so, make sure that the groove in the mat is at the back, in

• When this has been completed your helper can then carefully tilt the speaker back into its stable upright position.

With AURUM loudspeakers you can choose between three modes of operation:

a) Conventional mode

Do not remove the jumpers, connect the speaker cable as shown in the illustration.

Before connecting up the speakers to your hi-fi or surround sound system, please ensure that the amplifier/receiver is switched off and its pilot light is not on. For connection, you will need a twin-core loudspeaker cable for each speaker cabinet. Make sure these cables are sufficiently long and cut them to a length that will

Connecting to the amplifier

subsequently enable you to lay them behind furniture or under the carpet where necessary. For cables more than 5 m in length we recommend a cross-section area of at least 2.5 mm2 per core in order to avoid any unnecessary loss of output. To enable optimum contact, about 10 mm of the cores at each end of the cable must be isolated, and thus bare.

Screw terminals

For connection, the speakers are provided with colour-coded screw terminals on the back of the cabinet. Loosen the screw terminals and feed the stripped end of the core into the hole that is now free. The two cores of speaker cables have

To ensure correct polarity, check that the core connected to the red “+” terminal of the speaker is also the core that is connected to the red “+” terminal of the amplifier and that the other core is connected to the black “-“ terminals of both the speaker and amplifier.

b) Biwiring mode

Remove the jumpers after loosening the four screw terminals on the back of the speaker and connect the cable as shown in the illustration.

c) Biamping mode

Remove the jumpers and connect the cables as shown in the illustration.

the two right-hand screw terminals and the midrange and tweeter via the two lefthand terminals. On the AURUM VULKAN VII and AURUM MONTAN VII the two screw terminals for the woofer are located below on the connection panel and those for the midrange and tweeter above.

Make sure you use the correct polarities in these modes and that you remove the jumpers on the speaker terminal to avoid damaging your amplifier.

Operation with a surround amplifier

Once you have positioned and connected your speakers as shown in the illustration, you should perform the necessary settings in the bass management system of your surround amplifier. Make sure you read the user manual supplied by your amplifier’s manufacturer before doing this.

Beware of clipping!

Even if an amplifier’s nominal output is significantly lower than the rated powerhandling capacity of the speakers connected to it, there is still every possibility that the speakers might be damaged if not used correctly. The nominal output quoted merely indicates the number of watts the amplifier is capable of delivering to the speakers with low distortion. If an amplifier is overloaded it delivers far more power on the one hand while adding destructive direct current as well as high-frequency oscillation on the other. This process is known as clipping and negatively affects the sound through severe distortion in loud passages of music. When distortion becomes audible you should turn the volume down straight away to avoid damaging the speakers. Amp-clipping is a typical indication of overloading and always occurs when the volume and/or tone controls is/are is turned up too high. Even when the tone controls are set in neutral (12 o’clock) position, conventional amps already reach their limits when subject to loud impulses as soon as the volume control is turned well beyond the 12 o’clock position.

Care of your loudspeakers

Your AURUM loudspeakers are best cleaned with a soft, dry cloth. The aluminium housing is best wiped in a longitudinal direction with a damp cloth. Do not use solvents. You should only clean the loudspeaker systems (woofer, midrange units, etc.) when they have become very dirty (small amounts of dust have no effect on the acoustics). Use a soft, dry cloth or a soft brush with very gentle pressure, otherwise there is a risk of damaging the diaphragms. We generally advise against cleaning the tweeter diaphragms because they are extremely sensitive to pressure!

If the silver front frame becomes dirty, spray dry foam cleaner (such as Centralin spray) onto dirty areas, leave to work in, then simply remove with a vacuum cleaner. Do not brush off black front frames, instead tap off or remove the dirt carefully with adhesive tape. On no account clean using anything damp!

Fault

Audible distortion even at low volume

Cause

a) Fault in the electronics

b) Fault in the speaker

Rectification

a) The fault lies in the electronics if the problem affects both speakers. Swap over the left and right speakers if only one speaker is affected. If the problem is still on the same channel, your electronics are faulty. The speaker is faulty if the problem is now on the other channel. b) Please contact your dealer or our service (tel. +49 (0) 511-7904-0).

Zunächst danken wir Ihnen dafür, dass sie sich für AURUM Lautsprecher entschieden haben. Es sind Musikliebhaber und Kenner wie Sie, für deren hohe Ansprüche wir Lautsprecher einer Güteklasse bauen, die weit über dem Durchschnitt liegt. Auch wenn Sie vieles vielleicht schon wissen, führen wir im folgenden einige Grundregeln auf, die es Ihnen ermöglichen, Ihre Lautsprecher optimal zu nutzen.

Sicherheitshinweise für passive Lautsprecher

Lesen Sie bitte die vorliegende Bedienungsanleitung sorgfältig durch und befolgen Sie bitte alle Schritte, die für die Inbetriebnahme angegeben sind. Deponieren Sie diese Anleitung so, dass Sie bei späteren Fragen schnell zur Hand ist.

• Die Standfestigkeit (insbesondere die großer Lautsprecher) ist stark von der Beschaffenheit des Untergrundes abhängig. Teppichboden verringert, z.T. erheblich, die Standfestigkeit. Schon ein mittelstarker Schlag kann einen Lautsprecher zum Umfallen bringen und birgt daher eine Verletzungsgefahr für in der Nähe befindliche Menschen oder Haustiere. Die Standfestigkeit kann durch den Einsatz sogenannter „Spikes“ deutlich verbessert werden, jedoch Vorsicht bei der Montage, da hier eine Verletzungsgefahr durch die scharfen Spitzen besteht oder auch eine Beschädigung des Untergrundes erfolgen kann. Auf glatten Böden lassen sich Lautsprecher mittels Klettverschlüssen oder doppelseitigem Klebeband befestigen. Lautsprecher dürfen keinesfalls als Sitzmöbel oder Kletterhilfen (Leiterersatz) benutzt werden!

• Verwenden Sie bitte ausschließlich Rollmöbel, Stative oder Wandbefestigungen und andere Geräte zum Anbringen und Draufstellen der Produkte, die beim Hersteller erhältlich sind und für oder mit dem Produkt vertrieben werden. Beachten Sie bitte, dass Tischgeräte oder Stative, auf denen die Produkte platziert werden, sehr vorsichtig zu bewegen sind, um Schäden oder Verletzungen durch ein Umkippen zu vermeiden. Bei einer Wandmontage ist besondere Sorgfalt auf eine ausreichend sichere Verschraubung aller Komponenten zu legen! Zusätzliche Sicherungseinrichtungen (Ketten, etc.) sollten montiert werden.

• Es sollte ein Standort für die Lautsprecher gewählt werden, der trocken und nicht zu kalt ist. Eine dauerhafte hohe Luftfeuchtigkeit oder starke Sonneneinwirkung (UV-Strahlung) kann Ihre Lautsprecher vorzeitig altern lassen und somit die Funktionsfähigkeit beeinträchtigen.

• Bei einer Überlastung der Lautsprecher durch sehr große Lautstärken ist das Durchbrennen einzelner Bauelemente auf den Frequenzweichen oder einzelner Lautsprecher nicht vollständig auszuschließen. In besonders ungünstigen Fällen kann sogar ein Brand innerhalb eines Lautsprechers in einem derartigen Überlastungsfall entstehen. Daher sollten Lautsprecher, die in diesem Grenzbereich betrieben werden, nicht unbeaufsichtigt sein.

• Bei hohen Lautstärken können an den Lautsprecheranschlussklemmen und Bauteilen Spannungen von 30 V bis 50 V anliegen. Vermeiden Sie daher unbedingt, nicht isolierte Anschlusskontakte der Lautsprecher während des Betriebes zu berühren. Weiterhin sollten keinesfalls Hände oder Arme in die Schallaustrittsöffnungen (Bassreflexrohre) gesteckt werden um Verletzungen zu vermeiden. Speziell Kinder und Haustiere sind hier besonders gefährdet.

• Aus Sicherheitsgründen untersagen wir generell das Öffnen von Lautsprechern im Betrieb oder im angeschlossenen Zustand, da, wie im oberen Absatz erläutert, Spannungen von bis zu 50 Volt im Inneren anliegen können.

• Bei unsachgemäßem Umgang mit der Netzspannung besteht Lebensgefahr!

Kein passiver Lautsprecher darf direkt an das elektrische Netz angeschlossen

werden!

Die Lautsprecheranschlussklemmen dürfen nur mit den betreffenden Verstärkeraus-

gängen verbunden werden. Eine irgendwie geartete Verbindung dieser Klemmen mit dem elektrischen Netz (230 V/115 V) ist nicht erlaubt und führt direkt zur sofortigen Zerstörung des Lautsprechers und aller angeschlossenen Produkte. Daher sollte es vermieden werden, die Kabelanschlüsse mit Steckern zu versehen die auch nur entfernt zu einer Verwechselung mit Netzsteckern führen könnte.

• Magnetisch nicht abgeschirmte Lautsprecher können das Fernsehbild verfärben oder verzerren. Ein Abstand von 50 cm ist im allgemeinen ausreichend, um derartige Störungen zu vermeiden. Vermeiden Sie bitte die Ablage von z.B. Kreditkarten, Disketten, Audio oder Videokassetten oder anderen Magnetträgern auf dem Lautsprecher. Die dort gespeicherten Informationen könnten zerstört werden. Ebenso sollten Magnetbandgeräte nicht in unmittelbarer Nähe betrieben werden.

• Sehr große Lautstärken im Dauerbetrieb werden nicht nur von Ihren Nachbarn als störend empfunden, sondern können auch für den Anwender zu gesundheitsschädlichen Auswirkungen führen!
