A Few Precautions

Please read this manual carefully. In addition to basic installation and operating instructions, it provides valuable information on various RMB-1095 system configurations as well as general information that will help you get optimum performance from your system. Please contact your authorized Rotel dealer for answers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments.

English

Save the RMB-1095 shipping carton and all enclosed packing material for future use. Shipping or moving the RMB-1095 in anything other than the original packing material may result in severe damage to your amplifier.

Be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will need in the event warranty service is ever required.

Placement

The RMB-1095 generates heat as part of its normal operation. The heat sinks and ventilation openings in the amplifier are designed to dissipate this heat. The ventilation slots in the top cover must be open. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating.

Likewise, remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its considerable bulk. Again, use common sense.

NOTE: The RMB-1095 has caster wheels at the rear to help position it.

About THX Ultra™

THX is an exclusive set of standards and technologies established by the world-renowned film production company, Lucasfilm Ltd. THX grew from George Lucas’ personal desire to make your experience of the film soundtrack, in both movie theaters and in your home theater, as faithful as possible to what the director intended.

Movie sound tracks are mixed in special movie theaters called dubbing stages and are designed to be played back in movie theaters with similar equipment and conditions. The soundtrack created for movie theaters is then transferred directly onto Laserdisc, VHS tape, DVD, etc., and is not changed for playback in a small home theater environment. THX engineers developed patented technologies to accurately translate the sound from the movie theater environment into the home, correcting the tonal and spatial errors that occur.

Before any home theater component can be THX Ultra certified, it must incorporate the THX technologies and also pass a rigorous series of quality and performance tests. Only then can a product feature the THX Ultra logo, which is your guarantee that the Home Theater products you purchase will give you superb performance for many years to come.

AC Power and Control

AC Power Input

Because of its high power rating, the RMB-1095 can draw considerable current and may tax your home’s electrical circuit. Therefore, it should be plugged directly into a 3pin polarized wall outlet. Do not use an extension cord. A heavy duty multi-tap power outlet strip may be used, but only if it (and the wall outlet) is rated to handle the current demanded by the RMB-1095.

NOTE: The RMB-1095 has a built-in surge attenuator to prevent opening the electrical circuit’s breaker or fuse at turn-on.

Be sure the POWER SWITCH on the front panel of the RMB-1095 is turned off (in the out position). Then, connect the supplied power cord

POWER CONNECTOR on the back panel

to the of the amplifier and to the AC power outlet.

Your RMB-1095 is configured at the factory for the proper AC line voltage in the country where you purchased it (either 115 volts AC or 230 volts AC with a line frequency of either 50 Hz or 60 Hz). The AC line configuration is noted on a label on the back panel.

NOTE: Should you move your RMB-1095 to another country, it is possible to configure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the RMB-1095 exposes you to dangerous voltages. Consult a qualified technician or the Rotel factory service department for information.

If you are going to be away from home for an extended period of time such as a monthlong vacation, it is a sensible precaution to unplug your amplifier while you are away.

Power Switch and Power Indicator

The power switch is located in the center of the front panel of your amplifier. To turn the amplifier on, push the switch in. The LED indicator above the switch will light, indicating that the amplifier is turned on. To turn the amplifier off, push the button again and return it to the out position.

Trigger ON/OFF Mode Selector

The Amplifier provides the option for manual or automatic power on/off operation. These modes are selectable using a toggle switch on the back panel.

With the switch in the +12V TRIGGER ON position, the amplifier is turned on automatically when a 12V trigger signal is present at the 3.5 mm Jack of TRIGGER IN on the rear panel. The amplifier will go into standby mode if the +12V signal is not present. The front panel POWER SWITCH overrides this function. It must be ON for the +12V trigger to work. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present.

12V Trigger Input and Output

The jack labeled IN is for connecting the 3.5mm Plug/Cable carrying a +12 volt trigger signal to turn the amplifier on and off. To use this feature the toggle switch must be set to the ON position. This input accepts any control signal (AC or DC) ranging from 3 volts to 30 volts.

The jack labeled OUT is for connecting another 3.5mm plug/cable to provide a 12V trigger signal to other components. The 12V output signal is available whenever a +12 volt trigger signal is applied to the IN connector.

RMB-1095 Five Channel Power Amplifier

Protection Circuitry

The RMB-1095 features a thermal protection circuit that protects the amplifier against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the RMB-1095 protection circuit is independent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of the output devices and shuts down the amplifier if temperatures exceed safe limits.

In addition, the RMB-1095 includes overcurrent protection which operates only when load impedances drop below 2 ohms. This protection is independent for the left, right and center channels with separate front panel

TION LEDS for each.

Most likely, you will never see this protection circuitry in action. However, should a faulty condition arise, the amplifier will stop playing and the will light.

If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to identify and correct the problem. When you turn the amplifier back on, the protection circuit will automatically reset and the

LEDS should go out.

In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation leading to an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage.

PROTECTION

Input Signal Connections

The RMB-1095 gives you a choice of two different kinds of input connections — conventional unbalanced RCA type connections (such as found on nearly all audio equipment) or balanced XLR-type connections for use with some high-end preamps or digital processors featuring this lower noise connection.

NOTE

: To prevent loud potentially damaging

noises, make sure the amplifier is turned off when you make any signal connections.

RCA Inputs (unbalanced)

See Figure 2

When a component with RCA connectors – such as a preamplifier or surround sound processor – supplies signals to the RMB-1095, the RCA-type phono plug inputs should be used.

If you are using one of the high-end preamplifiers or processors with low-noise balanced signal outputs to drive your RMB-1095, you may choose to use these low-noise XLR-type connections. See your authorized Rotel dealer for the appropriate cables.

Connect XLR audio interconnect cables from each of the outputs from the preamplifier or signal processor to the corresponding

INPUT of the RMB-1095.

BALANCED

DB25 Connector Input

The RMB-1095 is also equiped with a DB25 type input. This input is typically only used in professionally-installed custom systems. The DB25 input duplicates the function of the five RCA inputs. For information regarding how to use this input, contact your nearest authorized Rotel service center.

NOTE: When using the DB25 input you must insert the supplied open-circuit RCA plugs into the unbalanced inputs. Use only the open circuit plugs supplied with the RMB-1095; do not use “shorting plugs”. The open circuit plugs engage a switch under the center pin of the RCA connector that ensures the DB25 connector input has the proper impedance.

Speakers

Speaker Selection

The nominal impedance of the loudspeaker(s) connected to the RMB-1095 should be at least 4 ohms. As a general rule, only one speaker shoud be connected to each of the sets of speaker terminals. When two speakers are connected in parallel to one of the speaker terminals, the effective impedance the amplifier sees is cut in half. For example, when driving two pair of 8 ohm speakers, the amplifier sees a 4 ohm load. If you plan on connecting two speakers to one of the terminals of the RMB-1095, select speakers with a nominal impedance of 8 ohms or higher. Speaker impedance ratings are less than precise. In practice, very few loudspeakers will present any problems for the RMB-1095. See your authorized Rotel dealer if you have any questions.

Speaker Wire Selection

Use insulated two-conductor stranded wire to connect the RMB-1095 to the speakers. The size and quality of the wire can have an audible effect on the performance of the system. Standard speaker wire will work, but can result in lower output or diminished bass response, particularly over longer distances. In general, heavier wire will improve the sound. For best performance, you may want to consider special high-quality speaker cables. Your authorized Rotel dealer can help in the selection of appropriate cables for your system.

Polarity and Phasing

The polarity – the positive/negative orientation of the connections – for every speaker and amplifier connection must be consistent so all the speakers will be in phase. If the polarity of one connection is mistakenly reversed, bass output will be reduced and stereo imaging degraded. All wire is marked so you can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor. The wire may have clear insulation with different color conductors (copper and silver). There may be polarity indications printed on the insulation. Identify the positive and negative conductors and be consistent with every speaker and amplifier connection.

Connecting the Speakers

See Figure 2 The RMB-1095 has five sets of color coded

binding posts. These cept bare wire, connector lugs, or dual banana type connectors (except in the European Community countries where their use is not permitted).

Route the wire from the RMB-1095 to the speakers. Give yourself enough slack so you can move the components enough to allow access to the

Mais plus que tout, Rotel vous remercie pour l’achat de cet appareil, et souhaite qu’il vous apporte de nombreuses heures de plaisir musical.

11 Français

Pour démarrer

Merci d’avoir acheté cet amplificateur de puissance cinq canaux Rotel RMB-1095. Il␣ a été spécialement conçu pour contribuer à des heures et des heures de plaisir musical, que vous l’utilisiez dans une chaîne haute fidélité ou au sein d’un système Home Cinema.

Aucun appareil ne saurait surpasser le RMB-

1095. Le RMB-1095 est un amplificateur de

puissance cinq canaux de construction extrêmement robuste, capable de fournir une puissance très élevée telle qu’elle est demandée aujourd’hui par les sources les plus modernes. En fait, la limitation de l’amplificateur Rotel RMB-1095 sera le plus souvent celle des capacités de votre prise murale d’alimentation␣! Des composants de sortie indépendants de type discrets, une très grosse alimentation équipée de transformateurs toriques et de composants de premier choix, ainsi que le principe de conception Rotel «␣Balanced Design␣» garantissent des performances sonores remarquables. Sa très haute capacité en courant permet au RMB-1095 d’alimenter les enceintes acoustiques les plus difficiles, même celles d’une impédance de seulement 2␣ ohms.

N’oubliez jamais que le RMB-1095 est capable de fournir des puissances très élevées, jusqu’à 200 watts par canal sur 8␣ohms et 330␣ watts par canal sur 4␣ ohms␣ : vérifiez que vos enceintes sont bien en mesure de faire face à une telle puissance. Dans le doute, n’hésitez pas à demander conseil à votre revendeur agréé Rotel.

Le RMB-1095 ne présente aucune difficulté quant à son installation. Vous n’éprouverez aucun problème, surtout si vous connaissez déjà le principe des amplificateurs de puissance. Branchez des câbles de modulation Cinch-RCA à partir de votre préamplificateur ou processeur de signal, connectez vos enceintes acoustiques, puis écoutez␣ !

Quelques précautions

Veuillez lire ce manuel d’utilisation très soigneusement. Il vous donne toutes les informations nécessaires aux branchements et fonctionnement du RMB-1095. Si vous vous posez encore des questions, n’hésitez pas à contacter immédiatement votre revendeur agréé Rotel.

Conservez soigneusement l’emballage du RMB-1095. Il constitue le meilleur et le plus sûr moyen pour le transport futur de votre nouvel appareil. Tout autre emballage pourrait en effet entraîner des détériorations irréversibles à l’appareil.

Conservez la facture de votre appareil␣: c’est la meilleure preuve de votre propriété et de la date réelle d’achat. Elle vous sera utile en cas de nécessité de retour au service aprèsvente.

Positionnement

Comme la plupart des maillons haute fidélité traversés par des courants élevés, le RMB-1095 dégage une certaine quantité␣ de chaleur pendant son fonctionnement. C’est pourquoi il possède un radiateur de refroidissement interne et des ouïes de ventilation. Ne bloquez donc pas ses ouïes supérieures de refroidissement. Il doit y avoir environ 10␣ cm de dégagement tout autour lui pour permettre le bon fonctionnement de sa ventilation, et une bonne circulation d’air tout autour du meuble qui le supporte.

N’oubliez pas non plus, lors de son installation, qu’il s’agit d’un appareil lourd. L’étagère ou le support utilisés doivent être suffisamment robustes et rigides␣ : dans ce domaine, le sens commun s’applique.

NOTE␣ : le RMB-1095 est équipé de mini roulettes à l’arrière pour faciliter son déplacement.

Au sujet du THX Ultra™

THX représente un ensemble de paramètres et standards à respecter, établis par la firme de production de films internationalement réputée Lucasfilm Ltd. À l’origine, le standard THX vient du souhait de Georges Lucas de bénéficier, aussi bien dans les salles de cinéma professionnelles que pour les installations personnelles de Home Cinema, d’une qualité sonore équivalente à celle désirée par le réalisateur et l’ingénieur du son du film.

Les bandes sonores des films sont montées et mixées dans des «␣salles de cinéma␣» spéciales, appelées salles de montage, et sont conçues pour être ensuite diffusées dans des salles de cinéma présentant les mêmes caractéristiques acoustiques et un équipement équivalent. C’est cette même bande sonore qui est directement transférée sur un LaserDisc, une cassette VHS ou un disque DVD, sans aucune modification lorsqu’elle est écoutée dans un environnement grand public Home Cinema. Les ingénieurs THX ont donc développé un ensemble de technologies brevetées pour reproduire le plus précisément possible le son des salles de cinéma dans des intérieurs réduits, notamment en ce qui concerne les timbres et l’environnement spatial du son.

Pour qu’un maillon Home Cinema puisse recevoir l’agrément THX Ultra, il doit répondre à toutes ces technologies THX et donc passer une série de tests de qualité et de performances techniques très rigoureux. Seulement s’il a passé avec succès tous ces tests, il peut alors porter le logo THX Ultra. Il est pour vous la garantie que l’appareil en question est capable de vous donner des performances excellentes et conformes à vos souhaits, et ce pendant de très longues années.

Cependant, le RMB-1095 est également équipé d’entrées symétriques afin de compléter parfaitement les processeurs et les préamplificateurs offrant ce type de connexion par prises XLR, sans parasite, même sur de grandes longueurs.
