RA-1060 Stereo Integrated Amplifier
Speaker Outputs
See Figure 2
The RA-1060 has two sets of speaker outputs,
labeled SPEAKER A and SPEAKER B. The
speaker outputs are controlled by the switch
on the front panel.
Speaker Impedance
If only one set of speakers will be used at any
given time, the speakers may have an imped-
ance 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 loud-
speakers will present any problems for the
RA-1060. See your authorized Rotel dealer
if you have any questions.
Speaker Wire
Use insulated two-conductor stranded wire to
connect the RA-1060 to the speakers. The size
and quality of the wire can have an audible
effect on the performance of the system. Stan-
dard 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 spe-
cial high-quality speaker cables. Your autho-
rized Rotel dealer can help in the selection of
cables for your system.
Polarity and Phasing
The polarity – the positive/negative orienta-
tion of the connections – for every speaker and
amplifier 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 con-
ductors (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
amplifier connection.
nectors are red. Use high quality RCA cables
for connecting input source components to the
RA-1060. Ask your authorized Rotel dealer
for advice about cables.
Recorder Connections
See Figure 2
Tape inputs and outputs can be connected to
any record/playback device that accepts stan-
dard line level analog input and output sig-
nals. Typically that will be a conventional tape
recorder. There are two sets of tape connec-
tions on the back panel, labelled TAPE 1 and
TAPE 2.
When connecting a recorder to the RA-1060,
the outputs of the recorder must be connected
to the tape inputs of the RA-1060. Similarly
the tape outputs of the RA-1060 must be con-
nected to the inputs of the recorder. Be sure
to connect the left and right channels of each
device to the proper channels on the associ-
ated components. Use high quality connect-
ing 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.
Preamp Outputs
The RA-1060 has a pair of preamp outputs
that can send a variable gain signal to an ex-
ternal power amp or signal processor. The
preamp outputs are standard RCA-type out-
put 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-1060 to the correct chan-
nels of the amplifier.
AC Power and Control
AC Power Input
Because of its relatively high power rating, the
RA-1060 can draw considerable current. There-
fore, it should be plugged directly into a 2-
pin polarized wall outlet. Do not use an ex-
tension 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-1060 and all the other components
connected to it.
Speaker Connections
Turn off all the components in the system be-
fore connecting the speakers. The RA-1060
has color-coded speaker connectors on the
back panel. These connectors accept bare wire,
or connector lugs. (In non-EC markets, the con-
nectors also accept dual banana plugs.)
Route the wire from the RA-1060 to the speak-
ers. Give yourself enough slack so you can
move the components to allow access to the
speaker connectors. 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 counter-
clockwise) the binding post thumbscrews. Place
the connector lug or wire around the binding
post shaft. Turn the thumbscrews clockwise to
clamp the connector lug or wire firmly in place.
NOTE
: Be sure there are no loose wire strands
that could touch adjacent wires or connec-
tors.
Signal Connections
The RA-1060 has line level inputs for source
components, connections for audio tape decks,
and preamp output connections to send sig-
nals 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.
Line Level Inputs
See Figure 2
The RA-1060 has four pair of conventional RCA
input connectors for line level components such
as CD players, video cassette recorders, tun-
ers, Laser Disc players, or DVD players. These
inputs are labeled CD, TUNER, AUX 1, and
AUX 2.
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-
