Rotel was founded by a family whose passionate interest in music led them

to manufacture high-fidelity components of uncompromising quality.

Through the years, that passion has remained undiminished and the family

goal of providing exceptional value for audiophiles and music lovers,

regardless of their budget, is shared by all Rotel employees.

Rotel’s engineers work as a close team, listening to, and fine tuning, each

new product until it reaches their exacting musical standards. They are

free to choose components from around the world in order to make that

product the best they can. You are likely to find capacitors from the United

Kingdom and Germany, semiconductors from Japan or the United States,

while toroidal power transformers are manufactured in Rotel’s own factory.

We all have concerns about our environment. And, as more and more

electronics are produced it is especially important for a manufacturer to do all

it can to engineer products that have a minimum impact on the environment.

At Rotel, we are proud to do our part. We have reduced the lead content

in our products by using special lead-free ROHS solder and components.

Our engineers continually strive to improve power supply efficiency without

compromise to quality. When in standby mode Rotel products use minimal

power to meet global Standby Power Consumption requirements.

The Rotel factory is also doing their part to help the environment through

constant improvements to product assembly methods for a cleaner and

greener manufacturing processes.

All of us at Rotel thank you for buying this product. We are sure it will bring

A Few Precautions

WARNING: To avoid potential damage to your system, turn off ALL

the components in the system when connecting or disconnecting the

loudspeakers or any associated components. Do not turn the system

components back on until you are sure all the connections are correct

and secure. Pay particular attention to the speaker wires. There must

be no loose strands that could contact the other speaker wires, or the

chassis of the amplifier.

Please read this manual carefully. It provides information on how to incorporate

the RA-630 into your system as well as information that will help you get

optimum sound performance. Please contact your authorized Rotel dealer

for answers to any questions you might have. In addition, all of us at Rotel

welcome your questions and comments.

Save the shipping carton and all enclosed packing material for future use.

Shipping or moving the amplifier in anything other than the original packing

material may result in severe damage to your amplifier.

If included in the box please fill out and send in the owner’s registration

card. Also be sure to keep the original sales receipt. It is your best record

of the date of purchase, which you will need in the event warranty service

is ever required.

Placement

Like all audio components that handle low level signals, this amplifier

can be affected by its environment. Avoid placing the unit on top of other

components. Also avoid routing audio signal cables near power cords. This

will minimize the chance it will pick up hum or interference.

The unit generates heat as part of its normal operation. The heat sinks and

ventilation openings in the amplifier are designed to dissipate this heat. The

ventilation slots in the top cover must be open. There should be 10 cm (4

inches) of clearance around the chassis, and reasonable airflow through

the installation location, to prevent the amplifier from overheating.

Remember the weight of the amplifier when you select an installation location.

Make sure that the shelf or cabinet can support it. We recommend installing

the unit in furniture designed to house audio components. Such furniture is

designed to reduce or suppress vibration which can adversely affect sound

quality. Ask your authorized Rotel dealer for advice about component

furniture and proper installation of audio components.

Cables

Be sure to keep the power cords, digital signal cables and regular audio

signal cables in your installation away from each other. This will minimize

the chance of the regular audio signal cables picking up noise or interference

from the power cords or digital cables. Using only high quality, shielded

cables will also help to prevent noise or interference from degrading the

sound quality of your system. If you have any questions see your authorized

Rotel dealer for advice about the best cable to use with your system.

The RR-AX91 Remote Control

Some functions can be done with either the front panel controls, or the

supplied RR-AX91 remote control. When these operations are described,

the square call out numbers refer to the main unit, while the encircled letters

refer to the remote control.

Second Amplier Remote Code

The factory setting is remote code 1. If you find that the remote is conflicting

with other Rotel amplifiers, you can change to remote code 2 with the

following steps.

1. From the remote control press Tuner Land 2 Hat the same time to set

the remote control to send Audio Code 2.

2. Point the remote at the unit and press 2 Hbutton for 8 seconds. The

unit will show “Audio Custom Code 1 -> 2”.

3. Repeat the above procedure and press “1” button instead of “2” to

change the unit back to Code 1.

NOTE: The remote control can be used to operate the basic functions of

Rotel tuners and CD players. Remote control buttons labeled HMJK

can be used to operate CD or Tuner functions in your system. For the

remote to operate properly, make sure both the remote and the CD or

Tuner are both in same remote code, either Code 1 or 2.

AC Power and Control

AC Power Input u

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.

The unit does not draw high levels of current from the power outlet. However,

whenever possible, it should be plugged directly into a 2-pin polarized wall

outlet. Do not use an extension cord. A heavy duty multi-tap power outlet

strip may be used if it (and the wall outlet) can handle the current demanded

by the amplifier and all the other components connected to it.

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 1Aand Power Indicator 2

Press the front panel Power Switch button 1, to turn the unit on. The Power

Indicator light 2is 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-630. In Standby mode the

power LED remains illuminated, but the display is turned OFF.

10 RA-630 Stereo Integrated Amplifier

12V Trigger Out =

See Figure 4

Some audio components can be turned on automatically when they receive

a 12V turn on “signal”. The two 12V Trigger Outputs of the RA-630 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.

NOTE: If you are using other units in the series with Rotel Link, please

use the Rotel Link connection to turn the units on or off. Do not connect

both the Rotel Link and 12V trigger cables. The 12V trigger’s power

on or off features will override the Rotel Link features.

Protection Indicator 3

The amplifier has both thermal and over-current protection circuitry that

protects the amplifier against damage in the event of extreme or faulty

operating conditions. The protection circuits are independent of the audio

signal and have no impact on sonic performance. Instead, the protection

circuits monitor the temperature of the output devices and shut down the

amplifier if temperatures exceed safe limits.

Most likely, you will never see this protection circuitry in action. However,

should a faulty condition arise, the amplifier will stop playing and the LED

indicator on the front panel will light up.

If this happens, turn the amplifier off. Let it cool down for several minutes,

and attempt to identify and correct the problem that caused the protection

circuitry to engage. When you turn the amplifier back on, the protection

circuit will automatically reset and the indicator LED should go out.

In most cases, the protection circuitry activates because of a fault condition

such as shorted speaker wires, or inadequate ventilation leading to an

overheating condition. In very rare cases, highly reactive or extremely

low impedance speaker loads could cause the protection circuit to engage.

If the protection circuitry triggers repeatedly and you are unable to isolate

and correct the faulty condition, contact your authorized Rotel dealer for

assistance in troubleshooting.

Input Signal Connections w

See Figure 3

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 wand 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 w

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.

Digital Signal Inputs rt

See Figure 3

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 e

The amplifier has a set of preamp outputs. The currently selected source

input is available from this output. Typically the PRE OUT output is 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 Outputsy

See Figure 3

Speaker Selection

The speakers may have an impedance as low as 4 ohms when be used

at any given time. 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 amplifier has color-coded binding post type speaker connectors on the

back panel. These connectors accept bare wire, connector lugs, or dual

banana type connectors. (except in European Community countries where

their use is not permitted)

Route the wire from the amplifier 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.

Headphone Output 4

The headphone output allows you to connect headphones for private listening.

This output accepts a standard 3.5mm (1/8”) mini stereo headphone

connector. Plugging in a set of headphones will cut off the signal to the

speaker outputs. The settings of the Function Selector determines which

source is heard.

NOTE: Because the sensitivity of speakers and headphones can

vary widely, always reduce the volume level before connecting or

disconnecting headphones.

Remote Sensor 5

This remote sensor window receives IR commands from the remote control.

Please do not block this sensor.

Display 6

The front panel display shows the source selected, volume level and tone

settings.
