About Rotel

Our story began over 50 years ago. Over the decades, we have received

hundreds of awards for our products and satised hundreds of thousands

of people who take their entertainment seriously – like you.

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

to manufacture high-delity 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 ne 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 nd 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 efciency 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

you many years of enjoyment.

Getting Started

Thank you for purchasing the Rotel A14 Stereo Integrated Amplier. When

used in a high-quality music audio system, Rotel products will provide years

of musical enjoyment.

This amplier is a full featured, high performance component. All aspects

of the design have been optimized to retain the full dynamic range and

subtle nuances of your music. The unit has a highly regulated power supply

incorporating a Rotel custom-designed toroidal power transformer. This low

impedance power supply has ample power reserves, which enables the

amplier to easily reproduce the most demanding audio signals. This type

of design is more expensive to manufacture, but it is better for the music.

The printed circuit boards (PCB) are designed with Symmetrical Circuit

Traces. This ensures that the precise timing of the music is maintained and

faithfully recreated. The circuitry uses metal lm resistors and polystyrene

or polypropylene capacitors in important signal paths. All aspects of this

design have been examined to ensure the most faithful music reproduction.

The main functions of the A14 are easy to install and use. If you have

experience with other stereo systems, you shouldn’t nd anything perplexing.

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 unit 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 amplier in anything other than the original packing

material may result in severe damage to your amplier.

If included in the box please ll 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 amplier

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 amplier 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 airow through

the installation location, to prevent the amplier from overheating.

Remember the weight of the amplier 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 analog audio

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

the chance of the analog 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-AX1400 Remote Control

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

supplied RR-AX1400 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 nd that the remote is conicting

with other Rotel ampliers, you can change to remote code 2 with the

following steps.

1. From the remote control press Tuner

I

and 2

M

at the same time for 5

seconds, to set the remote control to send Audio Code 2.

2. Point the remote at the unit and press 2

M

button for 14 seconds. The

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

3. Repeat the above procedure and press “1” key 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 keys labeled

GHMN

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.

Remote Control Batteries

Two AAA size batteries (supplied) must be installed before the remote control

can be used. To install the batteries, remove the cover on the back of the

RR-AX1400. Install the batteries as shown in the illustration in the battery

well. Test the control for proper operation, then replace the cover. When the

batteries become weak the remote control won’t operate the A14 consistently.

Installing fresh batteries should eliminate the problem.

AC Power and Control

AC Power Input

s

Your unit is congured 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 conguration 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,

it should be plugged directly into a polarized wall outlet using the supplied

cable or other compatible cable as recommended by your authorized Rotel

dealer. 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 amplier 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

amplier (as well as other audio and video components) while you are away.

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 A14. In Standby mode the power

LED is red, but the display is turned OFF.

12V Trigger Connection

u

See Figure 5

Some audio components can be turned on automatically when they receive

a 12V turn on signal. The two 12V Trigger Outputs of the A14 unit provide

the required signal. Connect compatible components to the amplier with a

conventional 3.5mm mini plug cable. When the unit is in standby mode or

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

2

The amplier has both thermal and over-current protection circuitry that

protects the amplier 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

amplier if temperatures exceed safe limits.

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

should a faulty condition arise, the amplier will stop playing and will

display “AMP PROTECTION“ on the front panel. The power indicator 2

on the front panel will turn red.

If this happens, turn the amplier 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 amplier back on, the protection

circuit will automatically reset and the power indicator 2 should turn blue.

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

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

-

and Ground Connection (GND)

0

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

=qw

The CD, Tuner, and Aux inputs of the amplier 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

]

See Figure 4

There are two sets of digital inputs labeled 1 and 2 for COAXIAL and

OPTICAL respectively. Connect the COAXIAL or OPTICAL outputs of your

source component into these sockets. The digital signals will be decoded

and played by the amplier. The unit is capable of decoding PCM signals

up to 24 bit, 192kHz.

Preamp Output

[

The amplier has a set of preamp outputs labeled PRE OUT. The currently

selected source input is available from this output. Typically the PRE OUT

output is used to provide a signal to another integrated amplier or power

amplier, 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 Output.

Speaker Outputs

\a

See Figure 3

Speaker Selector Switch

5

The amplier has two sets of speaker outputs, labeled “SPEAKER A”

\

and

“SPEAKER B”

a

. The speaker outputs are controlled by the A-B speaker

selector buttons

5

on the front panel or J on the remote control.

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.

13

Polarity and Phasing

The polarity - the positive/negative orientation of the connections - for every

speaker and amplier 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 amplier connection.

Speaker Connection

Turn off all the components in the system before connecting the speakers.

The amplier 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 amplier 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

rmly in place.

Troubleshooting

Most difculties in audio systems are the result of incorrect connections, or

improper control settings. If you encounter problems, isolate the area of the

difculty, check the control settings, determine the cause of the fault and

make the necessary changes. If you are unable to get sound from the unit,

refer to the suggestions for the following conditions:

Power Indicator Is Not Illuminated

The Power Indicator and the basic items in the Display window should be

illuminated whenever the unit is plugged into the wall power outlet and the

Power button is pushed in. If it does not illuminate, test the power outlet with

another electrical device, such as a lamp. Be sure the power outlet being

used is not controlled by a switch that has been turned off.

Fuse Replacement

If another electrical device works when plugged into the power outlet, but

the Power Indicator still will not illuminate when the unit is plugged into

the wall outlet, it indicates that the internal power fuse may have blown.

If you believe this has happened, contact your authorized Rotel dealer to

get the fuse replaced.

No Sound

Check the signal source to see if it is functioning properly. Make sure the

cables from the signal source to the amplier inputs are connected properly.

Be sure the Input Source is set to the proper input. Check the wiring between

the amplier and the speakers.

fabriquer des maillons Haute Fidélité sans compromis aucun.

Depuis sa création, cette passion est restée intacte, et cette famille s’est

xée comme objectif de proposer à tous les audiophiles et mélomanes

les meilleurs appareils possibles, quel que soit leur budget. Une volonté

partagée par tous les employés de Rotel.

Les ingénieurs Rotel travaillent comme une équipe très soudée, écoutant,

peaunant chaque nouveau modèle jusqu’à ce qu’il atteigne exactement

leurs standards – très élevés – de musicalité. Ils sont libres de choisir des

composants en provenance du monde entier, an de concevoir le meilleur

produit possible. C’est ainsi que vous trouverez dans nos appareils des

condensateurs d’origine britannique ou allemande, des transistors japonais

ou américains, tandis que les transformateurs toriques sont toujours fabriqués

dans nos propres usines Rotel.

Nous sommes tous concernés par la qualité de l’environnement. Et, comme de

plus en plus de produits électroniques sont fabriqués puis éliminés quelques

années plus tard, il est désormais essentiel qu’un constructeur fabrique tous

ses produits en veillant à ce qu’ils aient un impact minimum sur la planète.

Chez Rotel, nous sommes très ers d’apporter notre pierre à ce nouvel édice.

Nous avons réduit la teneur en plomb de nos électroniques, en utilisant

notamment des composants et une soudure spéciale ROHS. Nos ingénieurs

travaillent en permanence pour améliorer le rendement des alimentations de

puissance sans compromettre leur qualité. C’est ainsi qu’en mode Standby,

les appareils Rotel consomment moins pour se conformer aux exigences

de la « Standby Power Consumption » qui limite la consommation en veille

des appareils électroniques.

L’usine Rotel participe également de façon active à la protection de

l’environnement au travers d’un processus de fabrication général amélioré

et toujours plus écologique et plus propre.

Tous les membres de l’équipe Rotel vous remercient pour l’achat de cet

appareil. Nous sommes persuadés qu’il vous offrira de nombreuses années

d’intense plaisir musical.
