RA‑1520 Stereo Integrated Amplifier
Input Signal Connections
See Figure 3
The RA-1520 has line level inputs for source components, connections
for audio tape decks, and preamp output connections to send signals to
an external power amplifier.
Note: To prevent loud, potentially damaging, noises, make sure
the system is turned off when you make any signal connections.
Phono Input e and Ground Connection w
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 u
The RA-1520 has three pair of conventional RCA input connectors for
line level components such as CD players, video cassette recorders,
tuners, Laser Disc players, or DVD players. These inputs are labeled CD,
TUNER, AUX.
The left and right channels are clearly labeled and should be connected
to the corresponding channels of the source component. The left RCA
connectors are white, the right connectors are red. Use high quality RCA
cables for connecting input source components to the RA-1520. Ask your
authorized Rotel dealer for advice about cables.
Recorder Connections io
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. There are two sets of
tape connections on the back panel, labelled TAPE 1 and TAPE 2.
When connecting a recorder to the RA-1520, the outputs of the recorder
must be connected to the tape inputs of the RA-1520. Similarly the
tape outputs of the RA-1520 must be connected to the inputs of the
recorder. 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 inputs can also be used for standard playback-
only source components, omitting the output connections.
Media Player Input 4
A 3.5mm (1/8”) stereo input socket for a “Media Player” is provided on
the front of the RA-1520 and is selected by turning the Listening input
selector to AUX. Any portable stereo cassette, compact disc player or
hard disc playback device can be connected via this input.
If the Media Player input is connected to the headphone outputs of the
player note that you may need to adjust the volume control on the player
for sound to be heard. If the sound is loud and distorted turn down the
volume on the player. If the sound is not loud enough, even when the
RA-1520 volume control is turned up fairly high, then carefully turn up
the volume control on the player.
Note: When the 3.5mm (mini jack) is inserted into the Media
Player socket the rear input called AUX is disconnected. Removing
the 3.5mm plug from the Media player socket will allow the rear
AUX input to function. On the RR-AT94 remote, use the Volume +
and – buttons to increase or decrease the volume level.
Preamp Outputs p
The RA-1520 has a pair of preamp outputs that can send a variable
gain signal to an external power amp or signal processor. The preamp
outputs are standard RCA-type output connectors, compatible with the
inputs of most power amplifiers. Use high quality cables and be sure to
connect the left and right channel outputs of the RA-1520 to the correct
channels of the amplifier.
AC Power and Control
AC Power Input \
Because of its relatively high power rating, the RA-1520 can draw
considerable current. Therefore, 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) is
rated to handle the current demanded by the RA-1520 and all the other
components connected to it.
Your RA-1520 is configured at the factory for the proper AC line voltage
in the country where you purchased it (USA: 120 volts/60Hz AC or CE:
230 volts/50 Hz AC). The AC line configuration is noted on a decal on
the back panel. Plug the supplied cord into the AC INPUT receptacle on
the back of the unit.
Note: Should you move your RA-1520 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 RA-1520 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
audio and video components while you are away.
POWER Button and Power Indicator 1
Press the front panel POWER button, to turn the RA-1520 on. The power
indicator light ring around the power button and the MUTE function LED
are illuminated when the RA-1520 is on. Press the POWER button again
to turn the RA-1520 off. Once the RA-1520 has been turned on with the
front panel button, it can be switched between normal operating mode
and Standby mode with the POWER button on the RR-AT94. Also, when
in Standby mode, it can be turned on by pressing one of the LISTENING
input buttons.
12V TRIGGER Connection y
Several Rotel amplifiers can be turned on and off using a 12 volt signal,
provided by the 12V TRIGGER connection. When the RA-1520 is
activated, a 12 volt DC signal appears at this connector and will turn
on an amplifier. When the RA-1520 is turned off, the trigger signal is
interrupted and the external amplifier will be turned off.
