A Word About Watts
The RMB-1587MKII power output is quoted as 250 watts for each channel
into 4 ohms, when seven channels are operating together at full power.
Rotel has chosen to specify the power output in this way because, in
Rotel’s experience, it gives the truest value of the receiver or amplier’s
power capability.
When comparing specications for different products, you should be
aware that power output is often specied in other ways, so you may
not be comparing like with like.For example, the power output may be
quoted with only one channel operating, giving a higher maximum gure.
A loudspeaker’s impedance rating indicates the electrical resistance or
load it offers when connected to the amplier, usually 8 ohms or 4 ohms.
The lower the impedance, the more power the speaker will need. In effect,
a 4 ohm speaker will require twice as much power as an 8 ohm speaker.
However, Rotel ampliers are designed to work into any speaker impedance
between 8 and 4 ohms, and with all the channels working up to their full
power. Because the Rotel design is optimized for use with all channels
operating together, Rotel is able to specify the true power output for
both channels.
This can be important for your enjoyment, too. When watching movies,
it’s nice to have the amplier able to reproduce full power into all the
channels at the same time, especially in the case of a volcano exploding!
Getting Started
Thank you for purchasing the Rotel RMB-1587MKII Seven Channel Power
Amplier. When used in a high-quality music or home theater system,
your Rotel product will provide years of musical enjoyment.
The RMB-1587MKII is high-power amplier, providing the highest level
of audio performance. Discrete output devices, a massive power supply,
premium components, and Rotel’s Balanced Design ensure superb
sound quality. High current capability allow the RMB-1587MKII to drive
the most demanding loudspeakers.
Be aware that the RMB-1587MKII is capable of high power levels, in excess
of 250 watts respectively per channel. Make sure that your speakers can
handle the power of the amplier. If in doubt about your speakers, ask
your local Rotel audio dealer for advice.
The amplier is straightforward in the installation and operation. If you
have experience with other stereo power ampliers, you shouldn’t nd
anything perplexing. Simply plug in the associated components and enjoy.
A Few Precautions
WARNING: To avoid potential damage to your system, turn off ALL
the components in the system when connecting or disconnecting the
loudspeakers or any associated components. Do not turn the system
components back on until you are sure all the connections are correct
and secure. Pay particular attention to the speaker wires. There must
be no loose strands that could contact the other speaker wires, or the
chassis of the amplifier.
Please read this manual carefully. In addition to installation and operating
instructions, it provides valuable information on various system congurations
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.
Save the shipping carton and all enclosed packing material for future
use. Shipping or moving the amplier in anything other than the original
packing material may result in severe damage that is not covered by
the warranty.
If included in the box please ll out and send in the owner`s registration
card. Also 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 required.
Placement
The RMB-1587MKII generate heat as part of its normal operation. The
heat sinks and ventilation openings in the amplier are designed to
dissipate this heat. The ventilation holes 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
amplier from overheating.
Remember the weight of the amplier when you select an installation
location. Make sure that the shelf or cabinet can support it. We recommend
installing the unit in furniture designed to house audio components.
Such furniture is designed to reduce or suppress vibration which can
adversely affect sound quality. Ask your authorized Rotel dealer for advice
about component furniture and proper installation of audio components.
AC Power and Control
AC Power Input 66
Your amplier is congured at the factory for the proper AC voltage in
the country where you purchased it, either 120 volts or 230 volts. The AC
line conguration is noted on a decal on the back panel.
NOTE: Should you move your amplifier to another country, it may be
possible to reconfigure it for use on a different line voltage. Do not
attempt to perform this conversion yourself. Opening the enclosure of
the amplifier exposes you to dangerous voltages. Consult a qualified
service person or the Rotel factory service department for information.
NOTE: Some products are intended for sale in more than one country
and as such are supplied with more than one AC cord. Please use only
the cord appropriate for your country/region.
Because of its high power rating, the amplier can draw considerable
current. Therefore, it should be plugged directly into a wall outlet. The
RMB-1587MKII must be plugged into a 3-pin polarized outlet. Do not use
an extension cord. A heavy duty multi-tap power outlet strip may be used
if it (and the wall outlet) is rated to handle the current demanded by the
amplier and all the other components connected to it.
Be sure the POWER SWITCH 11on the front panel of the amplier is turned
off (in the “out” position). Then, connect the supplied power cord to the
Power Connector 66 on the rear of the unit and the AC power outlet.

10 RMB-1587MKII Seven Channel Power Amplier
NOTE: To prevent loud potentially damaging noises, make sure the
amplifier is turned off when you make any changes to the input signal
configuration.
Select high quality audio interconnect cables. Connect each of the
outputs from the preamplier or signal processor to the corresponding
input of the amplier.
Speaker Connection
Speaker Selection
We recommend using loudspeakers with a nominal impedance of 4 ohms
or higher with the RMB-1587MKII. You should exercise some caution in
driving multiple pairs of speakers in parallel conguration, because the
effective impedance the amplier sees is cut in half. For example, when
driving two pair of 8 ohm speakers, the amplier sees a 4 ohm load.
When driving multiple speakers in parallel, it is recommended that you
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-1587MKII. See your authorized
Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the amplier 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
cables for your system.
Polarity and Phasing
The polarity – the positive/negative orientation of the connections – for
every speaker and amplier connection must be consistent so all the
speakers will be in phase. If the polarity of one connection is 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 amplier
connection.
Speaker Connections 55
NOTE: The following text describes both binding post and plug-in
connections. DO NOT use both connection methods in combination
to connect multiple speakers.
Turn off all the components in the system before connecting the speakers.
The RMB-1587MKII have two color coded binding posts, two for each
channel. These connectors accept 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 amplier to the speakers. Give yourself enough
slack so you can move the components to allow access to the speaker
connectors.
If you are going to be away from home for an extended period of time
such as a month-long vacation, it is a sensible precaution to unplug your
amplier (as well as other audio and video components) while you are away.
Power Switch and Power Indicator 11
The power switch is located on the front panel of your amplier. To turn
the amplier on, push the switch in. The ring around the switch will light
up, indicating that the amplier is turned on. To turn the amplier off,
push the button again and return it to the “out” position.
NOTE: Place the self adhesive ring over the light surrounding the Power
switch if the blue light is too bright.
12 Volt Trigger Input and Output 22
The jack labeled IN is for connecting the 3.5mm MONO Plug/Cable
carrying a +12 volt trigger signal to turn the amplier on and off. When
the trigger is connected to the IN the amplier automatically uses the
12V trigger power control function. 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 MONO 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 Circuitry 11
The RMB-1587MKII feature thermal and over-current protection circuits
that protect against potential damage in the event of extreme or faulty
operating conditions. Unlike many designs, these protection circuits are
independent of the audio signal and have no impact on sonic performance.
Instead, the protection circuits monitors the temperature of the output
devices and the current they are handling and shuts down the amplier
if operating conditions exceed safe limits.
Most likely, you will never see this protection circuitry in action. However,
should a faulty condition arise, the amplier will stop playing and the
Power Indicator on the front panel will blink.
If this happens, turn the amplier off, let it cool down for several minutes,
and attempt to identify and correct the problem. When you turn the
amplier back on, the protection circuit will automatically reset and the
Power Indicator should light up, indicating that the amplier is turned
on normal.
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.
If the protection circuitry triggers repeatedly and you are unable to isolate
and correct the faulty condition, contact your authorized Rotel dealer for
assistance in troubleshooting.
Input Signal Connections 3
The RMB-1587MKII have conventional RCA type input connectors, the type
found on nearly all audio equipment. The RMB-1587MKII also includes
Balanced input connectors. Only one set of inputs should be connected.
Never connected both Balanced and RCA inputs at the same time.

11
If you are using dual banana plugs, connect them to the wires and then
plug into the backs of the binding posts. The thumbscrews of the binding
posts 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 binding posts, separate the wire
conductors and strip the insulation from the end of each conductor. Be
careful not to cut into the wire strands. Unscrew (turn counterclockwise)
the binding post. Place the connector lug or wire around the binding
post shaft. Turn the binding post clockwise to clamp the connector lug
or wire rmly in place.
NOTE: Be sure there are no loose wire strands that could touch
adjacent wires or connectors.
Cooling Fans
The Rotel RMB-1587MKII amplier is equipped with four cooling fans
to help ventilate the internal components. The rear panel of the RMB-
1587MKII includes a 2 position fan selection switch including Fan OffFan Off and
Fan AutoFan Auto. Please select the fan selection that best suits the installation
and cooling requirements.
NOTE: The RMB-1587MKII produces significant power and associated
heat - even with the cooling fans in use. Appropriate installation and
ventilation is required to ensure proper operation.
Troubleshooting
Most difculties in audio systems are the result of incorrect connections,
or improper control settings. If you encounter problems, isolate the area
of the difculty, check the control settings, determine the cause of the
fault and make the necessary changes. If you are unable to get sound
from the amplier, refer to the suggestions for the following conditions:
Power Indicator Is Not Illuminated
No main power to the amplier. Check the front panel power switch.
Make sure that it is set to the on position. Check AC power connections
at the amplier and the AC outlet.
Fuse Replacement
If another electrical device works when plugged into the power outlet,
but the Power Indicator of the unit does not light when plugged into
the same outlet and the Power Switch is pushed in, it indicates that the
internal power fuse may have blown. If you believe this has happened,
contact your authorized Rotel dealer to get the fuse replaced.
No Sound
If the amplier is getting AC power, but is producing no sound, check the
Protection indicator on the front panel. If it is lit, see below. If not, check
all of your connections and control settings on associated components.
Protection Indicator
The front panel POWER indicator is blinking when the amplier protection
circuits have shut off the amplier. 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
amplier 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 amplier itself.
