Getting Started

Thank you for purchasing the Rotel RMB-1066
Six-Channel Power Amplifier. When used in
a high-quality music or home theater system,
your Rotel amplifier will provide years of
musical enjoyment.

The RMB-1066 is a sophisticated six-channel
power amplifier. Discrete output devices, a
massive power supply with toroidal trans­former, premium components, and Rotel’s
Balanced Design ensure superb sound qual­ity. High current capability allows the RMB­1066 to drive difficult speaker loads with ease.

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-1066 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 unobstructed. 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 weight.

AC Power and Control

AC Power Input

The RMB-1066 is supplied with the proper AC
power cord. Use only this cord or an exact
equivalent. Do not use an extension cord. A
heavy duty multi-tap power outlet strip may
be used, but only if it is rated to handle the
current demand of the RMB-1066.

Be sure the Power Switch on the front panel
of the RMB-1066 is turned off. Then, plug one
end of the cord into the AC power connector

on the back panel of the amplifier. Plug

the other end into an appropriate AC outlet.

Your RMB-1066 is configured at the factory
for the proper AC line voltage in the country
where you purchased it (USA: 115 volts/60
Hz , Europe: 230 volts/50 Hz). The AC line
configuration is noted on a label on the back
panel.

NOTE: Should you move your RMB-1066
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-1066 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, it is a sensible
precaution to unplug your amplifier.

Power Switch and
Indicator

The Power Switch is located on the front panel.
To turn the amplifier on (or to activate either
of the optional automatic power-on modes),
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.

Auto Turn On/Off Mode
Selector

The RMB-1066 provides three options for
manual or automatic power on/off operation.
These modes are selectable using a three­position slide switch on the back panel:

• With the switch in the OFF position, the
amplifier is turned on or off manually us­ing the front panel power switch. Use this
mode if you are using a switched AC out­let to control power to the amplifier.

• With the switch in the SIGNAL SENSING
position, the amplifier turns on automati­cally when a signal is sensed at the inputs.
The amplifier will go into standby mode after
five minutes with no signal. The front panel
power switch overrides this function. It must
be ON for the signal sensing to work. Turn­ing the switch OFF cuts power to the am­plifier, regardless of whether or not a sig­nal is present.

• With the switch in the +12V TRIG. position,
the amplifier is turned on automatically
when a 12 volt trigger signal is applied to
the 3.5mm Jack to the left of the switch. The
amplifier will go into standby mode after
5 minutes with no signal if the +12 volt 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 trig-

ger signal to turn the amplifier on and off.
To use this feature the adjacent slide switch
must be placed to the left position (see previ­ous section). 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.

Protection Indicators

Thermal and protection circuits protect the am­plifier against potential damage in the event
of extreme or faulty operating conditions.
Unlike many designs, the RMB-1066’s 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 safe limits are exceeded.

In addition, the RMB-1066 includes overcurrent
protection which operates only when load im­pedances drop too low. This protection is in­dependent for each of the three pair of chan­nels with separate front panel PROTECTION
LEDS for each.

Should a faulty condition arise, the amplifier
will stop playing and one or more of the PRO­TECTION LEDS on the front panel 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 PROTECTION
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.

Stereo/Bridged Mono
Mode Selection

It is useful to think of the RMB-1066 as three
stereo amplifiers in a single chassis. Each of
the three pair of amplifier channels can be
operated in Stereo or Bridged Mono mode.

• Stereo mode: Conventional 2-channel stereo
operation for a pair of amplifier channels.
Minimum speaker load: 4 ohms.

• Bridged Mono mode: Bridged Mono mode
more than doubles the power into a single
speaker. Minimum speaker load: 8 ohms.

The two modes are selected by three rear panel
switches, one for each pair of channels. Ste­reo or Bridged Mono configuration is inde­pendent for each pair of channels. You can
configure some pairs of channels in Stereo
mode and others in Bridged Mono mode.

Input Select Switches
Bridged Mono LEDs

A rear panel switch adjacent to the inputs
selects Stereo mode or Bridged Mono mode
for each of the three pair of amplifier chan­nels.

For Stereo mode: Slide the switch asso­ciated with the desired pair of amplifier chan­nels to the right, use both LEFT and RIGHT input
connectors, and connect one speaker to each
pair of speaker connectors.

NOTE:

For groups “B” and/or “C”, you
can also place the INPUT SELECT switch in
the center LINK position for Stereo mode.
This routes the input signals from the “A”
group to the inputs for that pair of ampli­fier channels.

For Bridged Mono mode: Slide the switch
to the left, use only the LEFT INPUT connec­tion, and connect only one speaker to the two
outer speaker connectors. The BRIDGED
MONO LED will light to indicate Bridged Mono
mode.

Signal Connections

The RMB-1066 provides standard conven­tional input connections — unbalanced RCA
type connections as found on nearly all au­dio equipment.

There is also a pair of SIGNAL OUTPUT LINK
connections for passing the input signal con­nected to the “A” pair of channels on to an­other audio component. Additionally, the input
signal to the “A” pair of channels can be
automatically linked to the inputs for the “B”
and/or “C” channels, so that a separate in­put signal cable is not required for those chan­nels, for example in large systems where the
RMB-1066 is being used to drive multiple pairs
of speakers in stereo mode.

RCA Inputs

See Figures 2 and 3

There are two RCA inputs for each of the three
pair of amplifier channels. These RCA inputs
accept audio signals from preamplifiers or
surround sound processors. Use high qual­ity audio interconnect cables for best perfor­mance.

NOTE: You can link the inputs for group
“A” to groups “B” and/or “C” by placing
the INPUT SELECT switch in the center LINK
position. No input connection is required
for that group. Placing the switch in this
position leaves that pair of channels in Ste­reo mode.

For Bridged Mono operation, use only
the LEFT INPUT for that pair of amplifier chan­nels. Connect one output channel of your
preamp to the LEFT INPUT on the RMB-1066.
Make sure that the INPUT SELECT SWITCH
selector switch is in the BRIDGED position.

Input Level Controls

Three controls on the front panel, one for each
pair of amplifier channels, provide input level
adjustments. These allow you to adjust the gain
of the amplifiers to match other components
in an elaborate system.

Use a small flat blade screwdriver to turn the
control clockwise to increase gain. Turn the
control counterclockwise to reduce gain.

Signal Output Link

This pair of RCA connections can be used to
pass unprocessed input signals to another
audio component, for example to “daisy­chain” an additional amplifier to drive a sec­ond set of speakers.

The input signals connected to the “A” inputs
are always available at SIGNAL OUTPUT LINK
connections. These input signals can also be
linked to the “B” and/or “C” inputs by play­ing the INPUT SELECT switch associated with
that pair of inputs in the LINK position.

Speakers

The RMB-1066 has three groups of speaker
connectors, one for each pair of amplifier
channels. These can be used to connect two
loudspeakers in Stereo mode, or to connect
one loudspeaker in Bridged Mono mode.

Speaker Selection

The nominal impedance of the loudspeaker(s)
connected to the RMB-1066 in the various
operating modes should be:

• Stereo mode: minimum 4 ohms

• Bridged Mono mode: minimum 8 ohms
When driving multiple pairs of speakers
connected in parallel to a single amplifier
channel, the effective impedance the am­plifier sees is cut in half. For example, when
driving two 8 ohm speakers, the amplifier
sees a 4 ohm load. When driving multiple
speakers in parallel, select speakers with
a nominal impedance of 8 ohms or higher.

Speaker Wire Selection

Use insulated two-conductor stranded wire to
connect the RMB-1066 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.

RMB-1066 Six Channel Power Amplifier

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 very weak 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.

Speaker Connections

See Figures 2 & 3

The RMB-1066 has two pair of color coded
connections for each group of amplifier chan­nels. Labels above the connectors show the
proper connections for connecting speakers
in Stereo mode. Labels below show the proper
connections for Bridged Mono mode.

These speaker connectors accept bare wire,
connector lugs, or “banana” type connectors
(except in the European Community countries
where their use is not permitted).

Route the wires from the RMB-1066 to the
speakers. Give yourself enough slack so you
can move the components to allow access to
the speaker connectors.

If you are using banana plugs, connect them
to the wires and then plug into the backs of
the speaker connectors. The collars of the
speaker connectors should be screwed in all
the way (clockwise).

If you are using terminal lugs, connect them
to the wires. If you are attaching bare wires
directly to the speaker connectors, separate
the wire conductors and strip back the insula­tion from the end of each conductor. Be careful
not to cut into the wire strands. Unscrew (turn
counterclockwise) the speaker connector collar.
Place the connector lug around the shaft, or
insert the bundled wire into the hole in the shaft.
Turn the collars clockwise to clamp the con­nector lug or wire firmly in place.

NOTE: Be sure there are no loose wire
strands that could touch adjacent wires or

connectors.

In Stereo mode: Connect the left speaker
to the pair of speaker connectors labeled LEFT.
Connect the right speaker to the speaker
connectors labeled RIGHT. Follow the labels
printed above the connectors, observe cor­rect polarity, and make sure the INPUT SE­LECT switch for that pair of amplifier chan­nels is set to the STEREO position. (See Fig­ure 2)

In Bridged Mono mode: Connect each
speaker to the POSITIVE terminals of the LEFT
and RIGHT speaker connections on the back
of the RMB-1066. There are BRIDGED + and
– labels printed below each group of speaker
terminals to assist in maintaining proper polar­ity.

Connect the positive terminal of the speaker
to the speaker connector labeled LEFT + or
BRIDGED +. Connect the negative terminal of
the speaker to the speaker connector labeled
RIGHT + or BRIDGED –. Observe correct
polarity, and make sure the INPUT SELECT
switch is set to the BRIDGED position. (See
Figure 3)

Troubleshooting

Most difficulties in audio systems are the re­sult of poor or wrong connections, or improper
control settings. If you encounter problems,
isolate the area of the difficulty, check the
control settings, determine the cause of the fault
and make the necessary changes. If you are
unable to get sound from the RMB-1066, refer
to the suggestions for the following conditions:

Front Panel Power Indicator
Is Not Lit

No main power to the RMB-1066. Check AC
power connections at the amplifier and the
AC outlet. Check the front panel power switch.
Make sure that it is set to the ON position. If
using signal sensing auto power-on, make sure
that a signal is present at the inputs. If using
12V trigger power-on, make sure that a trigger
signal is present at rear panel screw termi­nals.

No Sound

If the amp is getting AC power, but is pro­ducing no sound, check the PROTECTION
INDICATORS on the front panel. If lit, see
below. If not, check all of your connections
and control settings on associated components.
Make sure that your input connections and
speaker connections match your selected ste­reo/mono configuration.

Protection Indicator Is Lit

The front panel PROTECTION INDICATORS
light when the RMB-1066 protection circuits
have shut off the amplifier. Typically, this oc­curs only when the ventilation openings are
blocked, when there is faulty speaker wiring,
or after a period of extreme use. Turn off the
system and wait for the amp to cool. Then push
the front panel power switch in and out to reset
the protection devices. If the problem is not
corrected or reoccurs, there is a problem with
the system or the amplifier itself.

Au sujet de Rotel

C’est une famille de passionnés de musique
qui a fondé Rotel, il y a maintenant plus de
quarante ans. Pendant toutes ces années, leur
passion ne s’est jamais émoussée et tous les
membres de la famille se sont toujours battus
pour fabriquer des appareils présentant un
exceptionnel rapport musicalité-prix, suivis en
cela par tous les employés.

Les ingénieurs travaillent toujours en équipe
réduite, écoutant et peaufinant soigneusement
chaque appareil pour qu’il corresponde
parfaitement à leurs standards musicaux. Ils
sont libres de choisir n’importe quels
composants dans le monde entier, uniquement
en fonction de leur qualité. C’est ainsi que vous
trouvez dans les appareils Rotel des
condensateurs britanniques ou allemands, des
transistors japonais ou américains, tandis que
tous les transformateurs toriques sont
directement fabriqués dans une usine Rotel.

L’excellente réputation musicale des appareils
Rotel a été saluée par la plupart des maga­zines spécialisés␣ ; ils ont reçu d’innombrables
récompenses, et sont choisis par de nombreux
journalistes critiques du monde entier, parmi
les plus célèbres, ceux qui écoutent de la
musique quotidiennement. Leurs commentaires
restent immuables␣ : Rotel propose toujours des
maillons à la fois musicaux, fiables et
abordables.

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.

Pour démarrer

Merci d’avoir acheté cet amplificateur de
puissance six canaux Rotel RMB-1066. 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.

Le RMB-1066 est un amplificateur de puis­sance six canaux particulièrement sophistiqué.
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-1066 d’alimenter les
enceintes acoustiques les plus difficiles.

Caractéristiques de
fonctionnement

• Trois paires de canaux d’amplification,
chaque paire pouvant être pontée (bridgée)
en monophonie (sélecteur en face arrière).
Configurations ainsi rendues possibles␣ : 6,
5, 4 ou trois canaux simultanément.

• Configuration de mise sous tension “␣ on/
off␣ ” sélectionnée par l’utilisateur␣ : manuelle,
automatique, par réception d’un signal à
l’entrée, ou contrôlée par l’envoi d’une
tension de commutation “␣ trigger␣ ” 12␣ volts.

• Contrôles de gain d’entrée en face avant.

• Diodes en face avant, indiquant le
fonctionnement éventuel en mono ponté
(bridgé) pour chaque paire de canaux
d’amplification.

• Circuit de protection avec indicateurs en
face avant.

• Sortie de renvoi du signal d’entrée, sans
modification, pour alimentation d’autres
amplificateurs indépendants.

Quelques précautions

Veuillez lire ce manuel d’utilisation très
soigneusement. Il vous donne toutes les infor­mations nécessaires aux branchements et
fonctionnement du RMB-1066. Si vous vous
posez encore des questions, n’hésitez pas à
contacter immédiatement votre revendeur
agréé Rotel.

Conservez soigneusement l’emballage du
RMB-1066. 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.

Installation

Le RMB-1066 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.

Alimentation secteur et
mise sous tension

Prise d’alimentation secteur

Le RMB-1066 est livré avec son propre câble
d’alimentation secteur. N’utilisez que ce câble,
ou sont équivalent exactement semblable.
N’utilisez pas de câble rallonge. Une prise
ou barrette multiple peut être utilisée, mais
uniquement si elle est capable de supporter
l’ampérage demandé par le RMB-1066.

Assurez-vous que l’interrupteur de mise sous
tension Power Switch, en face avant, est bien
en position “␣ éteint␣ ” (OFF). Branchez alors
le cordon secteur en face arrière sur la prise
repérée POWER CONNECTOR
l’autre extrémité dans la prise murale
d’alimentation.

Votre RMB-1066 a été configuré en usine pour
la tension d’alimentation secteur du pays pour
lequel il est prévu (115␣ volts/60␣ Hz ou 230
volts/50␣ Hz). Cette valeur est indiquée sur une
étiquette, en face arrière.
