12V Trigger Out
q
Some audio components can be turned on automatically when they receive a
12V turn on "signal". The two 12V Trigger Outputs of the amplifier provide
the required signal. Connect compatible components to the amplifier with a
conventional 3.5mm mini plug cable. When the unit is turned off, the trigger
signal is interrupted, and the components controlled by it are turned off.

Input Signal Connections

See Figure 2
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 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
r
The CD, Tuner, and Aux inputs of the amplifier are "line level" inputs. These
are for connecting components such as CD players or other audio playback
devices with an analog audio output.
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 Unit. Ask your authorized Rotel
dealer for advice about cables.

Recorder Connections t

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 Unit remember that the outputs of the
recorder must be connected to the tape inputs of the Unit. Similarly the tape
outputs of the Unit 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 supply a fixed level signal.

Preamp Outputs y

The unit 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 Outputs ui

See Figure 2

Speaker Selector Switch 4

The unit has two sets of speaker outputs, labeled "A"
speaker outputs are controlled by the switch

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 unit. See
your authorized Rotel dealer if you have any questions.

Speaker Wire Selection

Use insulated two-conductor stranded wire to connect the Unit 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.

Polarity and Phasing

The polarity – the positive/negative orientation 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
conductors (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.

Speaker Connection

Turn off all the components in the system before connecting the speakers.
The Unit has color-coded binding post type speaker connectors on the
back panel (except in European Community countries where their use is
not permitted). These connectors accept bare wire, connector lugs, or dual
banana type connectors.
Route the wire from the unit to the speakers. 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 counterclockwise) 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 connectors.
