AC Power and Control
AC Power Input
p
The RA-05 SE does not draw high levels of current from the power outlet. 
However, whenever possible, it should be plugged directly into a 2-pin 
polarized wall outlet. Do not use an extension cord. A heavy duty multi-
tap power outlet strip may be used if it (and the wall outlet) can handle 
the current demanded by the RA-05 SE and all the other components 
connected to it.
Your RA-05 SE is configured at the factory for the proper AC line voltage in 
the country where you purchased it (either 120 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 decal on the back panel.
NOTE: Should you move your RA-05 SE amplifier to another country, 
it is possible to reconfigure it for use on a different line voltage. Do not 
attempt to perform this conversion yourself. Opening the enclosure of 
the RA-05 SE exposes you to dangerous voltages. Consult a qualified 
service person 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 month-long vacation, it is a sensible precaution to unplug your 
amplifier (as well as other audio and video components) while you are 
away.
Power Switch

s
and Power Indicator
1
Press the front panel Power Switch button, to turn the RA-05 SE on. The 
Power Indicator light is illuminated when the RA-05 SE is on. Press Power 
Switch button again to turn the RA-05 SE off. 
Once the RA-05 SE has been turned on with the front panel power switch, 
it can be switched between normal operating mode and standby mode 
with the Power button 
s
on the RR-AT94 remote control.
See the “12V Trigger Outlet” section for more information on ways you 
may be able to turn on and off other components in your system along 
with the RA-05 SE.
Input Signal Connections
[See Figure

.]
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.
Phono Input
r
and Ground Connection
e
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 inputs. It will help prevent hum and noise. 
Line Level Inputs
t
The CD, Tuner, and Aux inputs of the RA-05 SE are “line level” inputs. 
These are for connecting components such as CD players, Hi Fi or NICAM 
Stereo video cassette recorders, tuners, Laser Disc players or the analog 
output from a CD-ROM drive.
The Left and Right channels are labeled and should be connected to the 
corresponding channels of the source component. The Left connectors 
are white, the Right connectors are red. Use high quality RCA cables for 
connecting input source components to the RA-05 SE. Ask your authorized 
Rotel dealer for advice about cables.
Recorder Connections
y
[See Figure
2
.]
The Tape 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 conventional tape recorder.
When connecting a recorder to the RA-05 SE remember that the outputs 
of the recorder must be connected to the tape inputs of the RA-05 SE. 
Similarly the tape outputs of the RA-05 SE 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.
NOTE: The Tape Outputs are not affected by the Volume, Balance or 
Tone controls. They receive a fixed level signal. 
Preamp Outputs
u
The RA-05 SE has a set of preamp outputs. The signal from the source 
selected with the Function Selector is always available from these outputs. 
Typically these outputs are used to provide a signal to another integrated 
amplifier or power amplifier, which is used to drive remote speakers
NOTE: Changes to the settings of the Volume, Balance or Tone 
controls affect the signal from the Preamp Outputs.

Speaker Selection
If only one set of speakers will be used at any given time, the speakers may 
have an impedance as low as 4 ohms. If there are times when both the A 
and B speakers will be used, all the speakers should have an impedance 
of 8 ohms or more. Speaker impedance ratings are less than precise. In 
practice, very few loudspeakers will present any problems for the RA-05 
SE. See your authorized Rotel dealer if you have any questions.
Speaker Wire Selection
Use insulated two-conductor stranded wire to connect the RA-05 SE 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.
