The RC-1090 is a full featured, high perfor-  
mance preamplifier. All aspects of the design  
have been optimized to retain the full dynamic  
range and subtle nuances of your music. The  
RC-1090 has a highly regulated power sup-  
ply incorporating a Rotel custom-designed to-  
roidal power transformer and custom-made  
slit foil capacitors. This low impedance power  
supply has ample power reserves, which en-  
ables the RC-1090 to easily reproduce the most  
demanding audio signals. This type of design  
is more expensive to manufacture, but it is  
better for the music.

RC-1090 Stereo Control Amplifier  
The RC-1090 has both XLR (balanced) and  
RCA cable main output and CD input connec-  
tions. The printed circuit boards (PCB) are de-  
signed with Symmetrical Circuit Traces. This  
insures that the precise timing of the music is  
maintained and faithfully recreated. The  
RC-1090 circuitry uses metal film resistors and  
polystyrene or polypropylene capacitors in im-  
portant signal paths. All aspects of this de-  
sign have been examined with the final goal  
being faithful reproduction of music.  
Placement  
Using the RR-969  
Like all audio components that handle low-  
level signals, the RC-1090 can be affected by  
its environment. Do not stack the RC-1090 on  
top of a power amplifier. This will minimize  
chance it will pick up hum or interference. We  
recommend installing the RC-1090 in furni-  
ture designed to house audio components.  
Such furniture is designed to reduce or sup-  
press vibration which can adversely affect  
sound quality. Ask your authorized Rotel dealer  
for advice about component furniture and  
proper installation of audio components.  
To operate the RC-1090 with the remote,  
activate the AUDIO mode, if necessary, by  
pressing the AUD button

Components  
To control other components with the RR-969,  
press the appropriate Device Selection but-  
ton. See the RR-969 manual for more infor-  
mation.  
The RC-1090 has a superb phono preamp  
stage, derived from Rotels finest phono pream-  
plifier, the RHQ 10. The preamp stage can  
be used with either a moving magnet (MM)  
or a moving coil (MC) phono cartridge. This  
shows our commitment to phono sound quality  
and our interest in the recreation of fine mu-  
sic.  
Cables  
Programming the RR-969  
Be sure to keep the power cords, digital sig-  
nal cables and regular audio signal cables  
in your installation away from each other. This  
will minimize the chance of the regular au-  
dio signal cables picking up noise or inter-  
ference from the power cords or digital cables.  
Using only high quality, shielded cables will  
also help to prevent noise or interference from  
degrading the sound quality of your system.  
If you have any questions see your authorized  
Rotel dealer for advice about the best cable  
to use with your system  
The RR-969 is pre-programmed to operate the  
RC-1090. Should the AUDIO mode of the  
RR-969 not operate the RC-1090, the pro-  
gramming may have been changed. To re-  
store the original programming, press the

NOTE: Pushing the PRELOAD button will  
erase all custom programming  
and learned commands, restoring the  
RR-969 to its factory settings.  
A Few Precautions  
Please read this manual carefully. It provides  
complete information on how to incorporate  
the RC-1090 into your system as well as gen-  
eral information that will help you get opti-  
mum sound performance. 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 com-  
ments.  
RR-969 Remote Control  
The RC-1090 includes a full-function learn-  
ing remote control that can operate up to nine  
other components, in addition to the RC-1090.  
AC Power and Control  
AC Power Input  
Connect the supplied power cord to the AC  
Input receptacle on the rear panel. Do not  
connect the power cord to the power outlet  
until all the audio input and output connec-  
tions have been made.  
A separate manual, included with the remote,  
gives detailed instrctions on programming and  
using the RR-969 to replace all of the remote  
controls in your system. To avoid duplication,  
we provide only basic information about us-  
ing the RR-969 to operate the RC-1090.  
Save the RC-1090 shipping carton and all en-  
closed packing material for future use. Ship-  
ping or moving the RC-1090 in anything other  
than the original packing material may re-  
sult in severe damage to your amplifier.  
It is usually best to plug the RC-1090 directly  
into a 2-pin polarized wall outlet. Avoid the  
use of extension cords. 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 components connected to  
it.  
Most of the RR-969 functions duplicate the front  
panel controls. In this manual the remote con-  
trol functions are covered in the same section  
as the front panel control operation. Numbers  
in gray boxes such as  
the front and rear panel control and connec-  
tion illustrations. See Figure 1 on page 3. Letters  
in gray boxes such as  
the RR-969 illustration. See Figure 2 on page  
3.  
Fill out and send in the owner’s registration  
card packed with the RC-1090. 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 ever  
required.

Auxiliary Power Outputs  
Some high output moving coil cartridges are  
designed to operate in the moving magnet po-  
sition. If you are in doubt about the correct  
setting, check the instruction manual for your  
phono cartridge for information regarding its  
output voltage and the expected input imped-  
ance. The Phono input has 47 kOhms input  
impedance and 2.5 mV sensitivity in the MM  
position and 100 Ohms input impedance and  
0.25 mV sensitivity in the MC position. If you  
still have questions about the proper setting  
of the phono input selector switch, consult your  
authorized Rotel dealer.  
NOTE: Should you move your RC-1090  
amplifier to another country, it is possible  
to reconfigure your amplifier for use on a  
different line voltage. Do not attempt to  
perform this conversion yourself. Opening  
the enclosure of the RC-1090 exposes you  
to dangerous voltages. Consult a qualified  
service person or the Rotel factory service  
department for information.  
(North American version only.)  
The RC-1090 has two switched outlets on  
the back panel. Power is available from these  
outlets when the RC-1090 is turned on.  
Power to these outlets is turned off when the  
RC-1090 is in Standby mode. These outlets  
can provide up to a total of 400 watts. They  
are appropriate for supplying power to sig-  
nal sources, such as CD players, tuners, or  
tape decks. They should not be used for  
power amplifiers. Connecting components  
that will draw more than 400 watts to these  
outputs could damage the Standby switch  
in the RC-1090.  
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 amplifier (as well as other au-  
dio and video components) while you are  
away.  
Phono Input  
and  
Ground Connection  
Plug the cable from the turntable into the  
appropriate left and right phono inputs. If the  
turntable has a “ground” wire connect it to  
the screw terminal to the left of the Phono in-  
puts. It will help prevent hum and noise.  
NOTE: Do not connect the power cord for  
a power amplifier to the auxiliary power  
outlets on the RC-1090. Power amplifiers  
often draw more power than these outlets  
can provide.  
Power/Standby Switch  
Remote Power Button  
Power Indicator  
,
and  
The Power/Standby switch  
is located on  
the left side of the front panel. When it is  
pressed the RC-1090 is turned on and the front  
panel displays and indicators are illuminated.  
Line Level Inputs  
The CD, Video, Tuner, and Aux inputs of the  
RC-1090 are “line level” inputs. These are for  
connecting components such as CD players,  
Hi Fi or NICAM Stereo video cassette record-  
ers, tuners for audio or video, Laser Disc play-  
ers or the analog output from a CD ROM drive.

[See Figure 3.]  
dicator light  
above the Standby button is  
always illuminated when the RC-1090 is con-  
nected to a “live” AC outlet.  
The RC-1090 has conventional RCA-type con-  
nectors for all inputs. In addition their is a set  
of balanced XLR type inputs for the CD input  
for use with high performance CD players that  
have balanced outputs.  
The Left and Right channels are clearly labeled  
and should be connected to the correspond-  
ing channels of the source component. The  
Left RCA connectors are white, the Right con-  
nectors are red. Use high quality RCA cables  
for connecting input source components to the  
RC-1090. Ask your authorized Rotel dealer  
for advice about cables.  
NOTE: The RC-1090 will be turned on  
and in the normal operating mode as soon  
as it is connected to the AC outlet. Be sure  
to set the Volume control to the minimum  
(full counterclockwise) position before con-  
necting the power cord.  
NOTE: To prevent loud noises that neither  
you nor your speakers will appreciate,  
make sure the system is turned off when  
you make any signal connections.

RC-1090 Stereo Control Amplifier  
Balanced XLR Outputs  
NOTE: The IR signals from the EXTERNAL  
REMOTE IN jack can be relayed to source  
components using external IR emitters or  
hardwired connections from the IR OUT  
jacks.  
Recorder Connections  
The Tape 1 and Tape 2 inputs and outputs can  
be connected to any record/playback device  
that accepts standard line level analog input  
and output signals. Typically that will be a con-  
ventional tape recorder.  
[See Figure 5 for Balanced XLR out-  
put connection illustration.]  
The XLR type outputs of the RC-1090 are “bal-  
anced” outputs. These provide the advantage  
of allowing the power amplifier to be placed  
a great distance from the RC-1090 without caus-  
ing loss of sound quality or picking up noise  
over the long cable run. Of course the associ-  
ated power amplifier must have balanced XLR-  
type inputs in order to use this feature.  
IR Output  
When connecting a recorder to the RC-1090,  
remember that the outputs of the recorder must  
be connected to the tape inputs of the RC-1090.  
Similarly the tape outputs of the RC-1090 must  
be connected to the inputs of the recorder. As  
with other sources be sure to connect the Left  
and Right channels of each device to the proper  
channels on the associated components. Use  
high quality connecting cables to prevent loss  
of sound quality.  
The IR OUT 1 & 2 jacks send IR signals re-  
ceived at the EXTERNAL REM IN jack to an  
infrared emitter placed in front of a source  
component or to Rotel CD players, cassette  
decks, or tuners with a compatible rear panel  
IR connector.  
When using the XLR outputs the Balanced  
Output switch  
must be set to the On po-

sition. Then simply connect a cable with XLR  
connectors to the RC-1090 outputs and power  
amplifier inputs. Be sure to connect the Left  
and Right channel outputs of the RC-1090 to  
the correct channels of the amplifier. If you  
have questions about the proper type of cable  
to use, consult your authorized Rotel dealer.  
See your authorized Rotel dealer for informa-  
tion on IR repeater systems.  
Output Connections  
NOTE: The RC-1090 has both RCA and  
XLR type output connectors. The two sets of  
outputs must not be used at the same time.  
NOTE: The EXT REM IN jack located next  
to the these jacks is for use with an external  
IR sensor duplicating the front panel IR sen-  
sor and located in the primary zone.  
12 Volt Trigger Outlet  
Some audio components can be turned on  
automatically when they receive a 12V turn  
on “signal”. The 12V Trigger Outputs of  
RC-1090 provides the required signal. Con-  
nect the compatible components to the  
RC-1090 with a conventional 1/8” miniplug  
cable. When the RC-1090 is in Standby mode,  
the trigger signal is interupted, so the com-  
ponents controlled by it are turned off.  
Balanced Output Switch  
Computer I/O Connector  
When the RCA outputs are used the Balanced  
Output switch must be set to the Off position.  
Set the switch in the On position when using  
the XLR Balanced outputs.  
The RC-1090 can be operated from a per-  
sonal computer running audio system control  
software from third-party developers. This con-  
trol is accomplished by sending the operat-  
ing codes normally sent by the RR-969 remote  
control over a hard-wired network connec-  
tion from the computer.  
RCA Outputs  
[See Figure 4 for RCA output connec-  
tion illustration.]

position. Then connect a set of cables between  
the outputs of the RC-1090 and the inputs  
of the amplifier. As always, use high quality  
cables and be sure to connect the Left and Right  
channel outputs of the RC-1090 to the cor-

Standby Power Indicator Is  
Not Lit  
No Sound  
Check the signal source to see if it is functioning  
properly. Make sure the cables from the sig-  
nal source to the RC-1090 inputs are connected  
properly. Be sure the Listening Selector is set  
to the proper input. Check the power ampli-  
fier for power and proper operation. Check  
all the wiring between the RC-1090 and the  
power amplifier, and the power amplifier and  
speakers.  
To clear all customized displays, turn the  
RC-1090 on. Then press the Listening Selec-  
tor Phono button together with the Recording  
Selector Off button. This will return all displays  
to their original settings.  
The Standby Power Indicator should be lit  
whenever the RC-1090 is plugged into the wall  
power outlet. If it does not light, test the power  
outlet with another electrical device, such as  
a lamp. Be sure the power outlet being used  
is not controlled by a switch that has been  
turned off.  
Troubleshooting  
Fuse Replacement  
Most difficulties in audio systems are the re-  
sult of incorrect connections, or improper  
control settings. If you encounter problems,  
isolate the area of the difficulty, check the con-  
trol settings, determine the cause of the fault  
and make the necessary changes. If you are  
unable to get sound from the RC-1090, refer  
to the suggestions for the following conditions:  
If another electrical device works when plugged  
into the power outlet, and the Standby Indi-  
cator still will not light when the RC-1090 is  
plugged into the wall outlet, 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 re-  
placed.
