the current demanded by the ampliﬁer and all the other components

connected to it.

Your unit is conﬁgured at the factory for the proper AC line voltage in the

country where you purchased it (either 120 volts AC or 230 volts AC with

a line frequency of either 50 Hz or 60 Hz). The AC line conﬁguration is

noted on a decal on the back panel.

NOTE: Should you move your amplifier to another country, it is possible to

reconfigure it for use on a different line voltage. Do not attempt to perform

this conversion yourself. Opening the enclosure of the unit exposes you

to dangerous voltages. Consult a qualified service person or the Rotel

factory service department for information.

NOTE: Some products are intended for sale in more than one country

and as such are supplied with more than one AC cord. Please only use

the one appropriate for your country/region.

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

ampliﬁer (as well as other audio and video components) while you are

away.

Power Switch

and Power Indicator

2

Press the front panel Power Switch button, to turn the unit on. The Power

Indicator light is illuminated when the unit is on. Press Power Switch

button again to turn the unit off.

When the power switch is in the ON position, the remote control ON

and OFF buttons may be used to activate the RA-11/RA-12. In Standby

mode the power LED remains lit, but the display is turned OFF.

Input Signal Connections

[See Figure

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 (GND)

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

The CD, Tuner, and Aux inputs of the ampliﬁer are “line level” inputs.

These are for connecting 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 unit. Ask your authorized

Rotel dealer for advice about cables.

Digital Signal Inputs

[See Figure

There are two sets of digital inputs labeled COAXIAL and OPTICAL. Connect

the COAXIAL or OPTICAL outputs of your player into these sockets. The

digital signals will be decoded and played by the ampliﬁer. The unit is

capable of decoding PCM signals up to 24 bit, 192kHZ.

Preamp Outputs

The ampliﬁer 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

Speaker Selector Switch

[See Figure

The ampliﬁer has two sets of speaker outputs, labeled “A”

and “B”

.The speaker outputs are controlled by the switch 6 on the front

panel.

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.
