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 ap-

propriate 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

The CD, Tuner, and Aux inputs of the RA-05

are “line level” inputs. These are for connect

ing 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. 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

remember that the outputs of the recorder must

be connected to the tape inputs of the RA-05.

Similarly the tape outputs of the RA-05 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 has a set of preamp outputs. The

signal from the source selected with the Func

tion Selector is always available from these

outputs. Typically these outputs are used to

provide a signal to another integrated ampli

ﬁer 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 sig

nal from the Preamp Outputs.

Speaker Outputs io

Speaker Selector Switch

[See Figure 2.]

The RA-05 has two sets of speaker outputs,

labeled “A”

and “B”

. The speaker

outputs are controlled by the switch

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

loudspeakers will present any problems for

the RA-05. See your authorized Rotel dealer

if you have any questions.

Speaker Wire Selection

Use insulated two-conductor stranded wire to

connect the RA-05 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 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 RA-05 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 RA-05 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 connec

tor 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.
