Rotel RA-1070 Stereo Amplifier User Manual


 
6
The RA-1070 printed circuit boards (PCB) are
designed with Symmetrical Circuit Traces. This
insures that the precise timing of the music is
maintained and faithfully recreated. The RA-
1070 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.
The RA-1070 has a superb phono preamp
stage. It is designed for use with popular mov-
ing magnet (MM) phono cartridges. This shows
our commitment to phono sound quality and
our interest in the recreation of fine music.
The RA-1070 is straightforward in its instal-
lation and operation. If you have experience
with other stereo systems, you shouldn’t find
anything perplexing. Simply plug in the as-
sociated components and enjoy.
A Few Precautions
Please read this manual carefully. It provides
complete information on how to incorporate
the RA-1070 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.
Save the RA-1070 shipping carton and all en-
closed packing material for future use. Ship-
ping or moving the RA-1070 in anything other
than the original packing material may re-
sult in severe damage to your amplifier.
Fill out and send in the owner’s registration
card packed with the RA-1070. 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.
Placement
Like all audio components that handle low-
level signals, the RA-1070 can be affected by
its environment. Do not stack the other com-
ponents on top of the RA-1070. That will
impede the ability of the amplifier to venti-
late the heat it generates. Also, do not stack
the RA-1070 on top of other components. This
will minimize chance the other components
will pick up hum or interference from the
RA-1070. We recommend installing the sys-
tem components in furniture designed to house
audio components. Such furniture is designed
to reduce or suppress vibration which can ad-
versely affect sound quality. Ask your autho-
rized Rotel dealer for advice about compo-
nent furniture and proper installation of au-
dio components.
Cables
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
RR-969 Remote Control
The RA-1070 includes a full-function learn-
ing remote control that can operate up to nine
other components, in addition to the RA-1070.
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 RA-1070.
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
indicate items on
the front and rear panel control and connec-
tion illustrations. See Figure 1 on page 3. Letters
in gray boxes such as
indicate items on
the RR-969 illustration. See Figure 2 on page
3.
Using the RR-969
To operate the RA-1070 with the remote,
activate the AUDIO mode, if necessary, by
pressing the AUD button
. The AUDIO
mode will remaine selected until another
DEVICE button is pressed.
Controlling Other
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.
Remote Sensor
The Remote Sensor is located to the right of
the Power button on the front panel. It picks
up the infra-red signals from the remote control.
Do not cover or block the sensor. It must be
clear of obstructions or the remote control will
not work properly. The operation of the Re-
mote Sensor can also be affected if it is ex-
posed to bright light, particularly sun light.
In addition remote control functions may not
work reliably if the batteries in the RR-969
are weak.
Programming the RR-969
The RR-969 is pre-programmed to operate the
RA-1070. Should the Audio mode of the
RR-969 not operate the RA-1070, the pro-
gramming may have been changed. To re-
store the original programming, press the
recessed Preload button
on the remote with
the tip of a ball point pen.
NOTE: Pushing the PRELOAD button will
erase all custom programming
and learned commands, restoring the
RR-969 to its factory settings.
