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

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 in-

puts. It will help prevent hum and noise.

Line Level Inputs

The CD, Tuner, and Aux inputs of the RA-02

are “line level” inputs. These are for connect-

ing components such as CD players, Hi Fi or

NICAM Stereo video cassette recorders, tun-

ers, 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-02. Ask

your authorized Rotel dealer for advice about

cables.

Recorder Connections

[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-02 re-

member that the outputs of the recorder must

be connected to the tape inputs of the RA-02.

Similarly the tape outputs of the RA-02 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

The RA-02 has a set of preamp outputs. The

signal from the source selected with the Function

Selector is always available from these out-

puts. Typically these outputs are used to pro-

vide a signal to another integrated amplifier

or power amplifier, which is used to drive

remote speakers

NOTE: Changes to the settings of the Vol-

ume, Balance or Tone controls affect the

signal from the Preamp Outputs.

Speaker Outputs

Speaker Selector Switch

[See Figure 2.]

The RA-02 has two sets of speaker outputs,

labeled “A”

and “B” . The speaker out-

puts are controlled by the switch

on the

front panel.

Speaker Selection

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-02. See your authorized Rotel dealer if you

have any questions.

Speaker Wire Selection

Use insulated two-conductor stranded wire to

connect the RA-02 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 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 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 po-

larity indications printed on the insulation. Iden-

tify the positive and negative conductors and

be consistent with every speaker and ampli-

fier connection.

Speaker Connection

Turn off all the components in the system be-

fore connecting the speakers. The RA-02 has

color-coded binding post type speaker connec-

tors on the back panel (except in European Com-

munity countries where their use is not permit-

ted). These connectors accept bare wire, con-

nector lugs, or dual banana type connectors.

Route the wire from the RA-02 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

connectors.
