About these instructions

The operation described here mainly refers to the use of the remote control handset (R/C).

Buttons with same or similar marking at the main unit have the same function like those of

the remote control (R/C).

Preparation for turning on

Place of erection

For setting up the unit please choose a location with sufficient air circulation around. That

prevents overheating. Don’t expose the unit to direct sunlight or other heat sources.

Do not pile up other units on top of your receiver. That would block the vent holes and

cause the device to overheat.

Before using the remote control

1. Please open the battery compartment.

2. Insert two batteries (1,5 V, size AAA). Please

make sure the polarity matches the marks

inside the compartment. Otherwise the r/c will

not work and may be damaged. Replace the

cover.

3. Please point the r/c towards the main unit when

operating its buttons.

The r/c works properly in a distance below 5m

and in an angle of up to 60° of the front of the

unit. No obstacles may stand in the way

between r/c and infrared sensor.

Should the r/c start to work unreliably replace

both batteries. We recommend using alkaline

batteries.

Batteries should not be disposed by

ordinary refuse disposal. Please lead empty batteries towards appropriate

collecting points. Never throw batteries into fire.

If you won’t use the r/c for some time, please remove the batteries from the

compartment, to prevent damage by leakage.

Connecting the antenna

For being able to receive radio programmes, connect the enclosed FM-projection

antenna for FM-reception and the AM-loop antenna for medium wave reception.

FM-antenna

For the FM-reception, please wind off the enclosed

projection antenna completely. Please push the

plug of the antenna on the central pin of the FM 75

ohm terminal. If your device is later working in

FM-operation, pass the antenna in such a way that

you achieve an optimal, noise-free reception.

If you connect an outside antenna, this antenna

must be grounded against lightning strikes. It is

essential that you discuss this matter with an

antenna expert. Never try to install an outside antenna on the roof of a house on

your own. This is very dangerous and may only be done by qualified service

experts.

AM-antenna

In order to install the enclosed medium wave antenna on a flat plane, assem-

ble it onto the stand as described in the following picture:

Connect the two connection wires of the medium wave antenna with the “AM

LOOP” terminals on the rear side of the receiver. Determine the optimal recepti

on position of the antenna.

Tips:

In order to avoid disturbing noises during medium wave reception, please keep the loop

antenna away from speakers and other technical equipment.

You can also connect the cable network of the Telekom to the FM 75 ohm terminal. In

most cases, it transmits radio programmes as well.

Connecting speakers

Important information

All shown or mentioned connection cables or not included in the delivery, they are

available in specialised trade.

Please switch off all involved devices before establishing the connections.

In order to prevent the development of humming and ambient noises, never pass the

connection cables together with speaker or power cords.

BEFORE connecting the speakers, check their impedance. Connect only speakers having

an impedance of 4 - 8 ohm or more.

On the red cable terminal, the positive speaker signal is present, on the black terminal,

the negative signal is present. When connecting the boxes you have to make sure that

you always connect the positive speaker signal with the positive (+) input and the

negative signal with the negative (-) input of the box.

We have installed 2 outputs for the subwoofer signal in your receiver: one speaker

output for connection a passive subwoofer and one line output for controlling an active

subwoofer. An active subwoofer has its own, installed amplifier, a passive one not. If you

already have a subwoofer but if you are not quite sure whether it is active or passive,

simply check if it has a power cord or a mains connection. If yes, it is active, if not, it is

passive. We only wanted to offer you both connection alternatives. It is not necessary to

simultaneously connect an active and a passive subwoofer.

For connecting the cables, remove ca. 10mm of the insulation

and twist the strands. Unscrew the desired connection terminal.

On the top and on the bottom you can now see openings in

which you can insert the denuded ends of the cable. Now

tighten the clamp again. Pay attention that blank ends of

already connected speaker cables never get in touch with each

other during operation. Otherwise, the device is damaged by

this short circuit.

Connecting audio und video devices

Video connection

In this section, you will learn how to connect DVD-players, tape decks or similar devices.

When establishing these connections, the device must also necessarily be switched off, as

otherwise voltage peaks may damage your speakers.

For the connection of DVD-players, satellite receivers and TVs, both S-Video and Video

inputs and outputs are available. If both connection possibilities are available, we

recommend you to use the S-Video connection as it provides higher picture quality. If you

connect, however, more video devices, it simplifies later operation if you connect all video

devices with the same kind of connection to the inputs of the AV-receiver. Otherwise, you

have to connect the TV via a video and S-Video cable. You also had to switch the input at the

TV if you switch to another video device at the receiver.

In brief:

Signals reaching the receiver via a video input can only reach the TV via the output

“Video-Monitor-Out”.

Signals reaching the receiver via a S-Video input can only reach the TV via the output

“S-Video-Monitor-Out”.

Tip:

When purchasing your AV-receiver, you watched out for quality. Do the same when

selecting your speaker and audio cables. Cross-section and conducting material play an

important role when it comes to music pleasure.

Analogue and digital connections

Many video components have analogue and digital outputs (e.g. DVD-players). We

recommend you to select the digital connection if possible, as only then can you enjoy DTS

and Dolby Digital Surround. With an analogue connection, your receiver can only operate in

the operation modes DOLBY PRO LOGIC II, MUSIC,

THEATER, HALL or 5 Stereo.

We have provided your receiver with connections of both

digital formats (coaxial and optical). These inputs are

named COAXIAL DIGITAL INPUT and OPTICAL DIGITAL

INPUT. If your video devices have coaxial and/or optical

digital outputs, connect them here.

Tip:

As a protection against dust, there is a cap on the optical

digital input. If you want to use the connection, remove the cap carefully. Keep it thoroughly

so that you can put it on again if you remove the optical cable from this connection again.

Audio connections

In addition to the digital inputs, your AV-receiver has

analogue audio inputs as well: AUX / VIDEO 1 / VIDEO 2 /

DVD. Here, you connect the analogue audio outputs of

your audio and video devices via RCA cable. In order to

connect an audiotape or cassette device, please use the

TAPE terminals. For a better overview and in order not to

interchange the stereo channels you should always

connect the white plug of the cinch cable with the white socket (left channel) and the red

plug with the red socket (right channel).

Tips:

We want to emphasis that the digital inputs of your AV-receiver can also be used for

connecting pure audio devices.

Please plug the connector firmly in the socket so that a reliable contact is established.

Positioning the boxes

For really enjoying the sound experience “Surround-Sound”, you should position the

speakers approximately like this:

1. TV monitor 2. Left front speaker 3. Subwoofer

4. Center speaker 5. Right front speaker 6. Left surround speaker

7. Right surround speaker 8. Listener’s position

The front speakers reproduce the front stereo effect, the center transmits in most of the

cases the performers’ dialogues. The surround speakers create the three-dimensional

sound impression by reproducing ambient noises complying with the scene. The subwoofer

produces the acoustic base and completes the sound experience.

The speaker arrangement cannot always be implemented optimally, the following points

should, however, always be considered when positioning the speakers:

The following applies to the front and center speakers:

Position these speakers all on the same level with each other, best on the listener’s ear

level.

These speakers should radiate in the direction of the listener.

The speakers should all have the same distance to the listener’s position.

The following applies to the surround speakers:

These speakers should exceed the listener’s ear level by approximately 1 meter.

The following applies to the subwoofer:

In the ideal case, the subwoofer should be situated between the two front speakers. If

this is not possible, experiment with the arrangement until you have the optimal overall

impression of your system. In many cases, the positioning in the corner of the room

assists in the sound propagation.

On the operation

Switching on/off

Connect the plug of the power cord with a properly connected 230V~ household mains

socket.

Press the power switch POWER in order to switch on the device. It is now in standby

mode and the blue indicator lamp is illuminated.

Press one of the input keys (Tape, AUX…DVD) or the POWER key of the remote control in

order to switch on the device.

If you want to switch off the device to standby operation, press the POWER key of the

remote control.

If you want to switch off the device completely, press the POWER switch at the device. In

standby operation, the receiver consumes some energy. Thus, you should switch it off if

you don’t use if for some period of time.

Volume control, muting

In the middle of the front panel, you find the VOLUME controller with which you can

control the volume. Turn the controller clockwise in order to increase the volume. Turn

the controller counter-clockwise in order to decrease the volume. The display shows you

the so-called attenuation in dB (decibel): Full volume means a signal attenuated by 0 dB.

So the display shows 0 dB (or MAX VOL). The lowest volume, -80 dB (or MIN VOL) means

the maximum attenuation of the signal. Alternatively, you can control the volume using

the VOL +/- keys of the remote control.

Press the MUTE key of the remote control if you want to mute the tone. Press the key

once again if you want to switch the tone on again.

Selecting inputs and operation modes

Press the key of the desired input channel TAPE, AUX, TUNER, VIDEO 1, VIDEO 2 or

DVD.

If you have selected the DVD or the Video 1 /

2-input, you must select if you want to

activate the respective analogue or digital

input. For doing so, press the DIGITAL IN

key.

Tips:

Via the input keys, the audio and video signals are switched. If you choose an input that

has no video connection (= Tape / AUX / TUNER), the device does not provide a picture at

the video or S-Video output.

We recommend you to reduce the volume before switching to other inputs and to then

increase it again slowly. This protects you from sudden volume fluctuations.

In the display, the incoming audio format is shown.

If you have activated one of the digital inputs, you can, depending on the incoming sound

material, select between 5.1-channel operation and 2-channel operation (=stereo with

subwoofer). Press the DTS / DOLBY DIGITAL key for 5.1-operation and the STEREO key

for 2-channel operation.

If your sound material is analogue, press the SURROUND MODE key and you can produce

a realistic, three-dimensional stereophonic sound which creates distances, movements and

relative positions and thus invests your cinema experience with an impressing presence. If

SURROUND MODE is activated (Movie or Music), the blue ring surrounding this key is

illuminated. In order to deactivate the surround mode, press the 2CH-key.

Or you select the function DOLBY PRO LOGIC II via the remote control. In this mode, the

5 output channels are decoded out of the stereo input signal.

Experiment with these settings until you have found a setting that is in your opinion

optimal. Orientate yourself always by the format of the present audio material. Information

on this can in most cases be found on the case of the data medium.

Phones output

On the left front side of the device, you find the phones jack PHONES. Connect here stereo

phones with a 6.3 mm jack plug. The speakers are switched off. We recommend you to

switch to STEREO so that you don’t miss anything in phones operation.

Display key

Press the DISPLAY key while the device is processing external signals in order to have the

format of the input signal shown.

Dimmer

If the brightness of the display disturbs you, press the DIMMER key in order to dim the

display in 2 steps.

The speaker configuration

In order to receive the best sound result with your AV-receiver, the correct configuration of

the speakers is absolutely necessary. The AV-R500 is indeed flexible enough for being able

to produce multi-channel surround sounds even without center speaker, for an optimal

result at the decoding of Dolby Pro Logic II, DTS and Dolby Digital, you need, however, at

least 5 speakers (left, right, center, back left, back right). In addition, we recommend

urgently using a subwoofer so that you are able to enjoy the entire sound range modern

DVD-films offer.

BASS mode

Using the key BASS MODE, you can select the bass mode suitable for the size and

capability of your front speakers. Mode 1 is designed so that no frequencies under 80 Hz are

released to the front speakers. If your front speakers are, however, large and powerful,

select Mode 2 so that the whole frequency spectrum is sent to the front speakers, as well.

Simply press the BASS MODE key repeatedly, the selected mode is shown in the display.

Switching off the subwoofer

If you have selected BASS mode 2 and if the device is not in the SURROUND mode, you can

switch the subwoofer on or off using the SUBWOOFER ON/OFF key. If you have

deactivated the subwoofer, the blue ring surrounding the SUB ON/OFF key goes out.

Delay time

For the Dolby Digital / Dolby Pro Logic II operation, you can set propagation delays in ms

(milliseconds) for the center and the surround speakers. Thus, the stereoscopic impression

can be intensified.

If you set the delay time in Dolby Digital operation, 15 ms are automatically added to the

surround channels in Dolby Pro Logic operation. The current setting appears in the display.

Press the DELAY TIME key of the remote control in Dolby Digital operation. In the display,

the speaker channel that is to be set is shown: “S” for the surround speakers, “C” for the

center speaker. Now press the +/- key in order to set the desired delay time for the

surround channels to 5,10 or 15 ms and for the center channel to 1, 2, 3, 4 or 5 ms.

In Dolby Pro Logic operation, the following delay times are available: for the surround

channels 10, 15, 20 or 25 ms and for the center channel 1, 2, 3, 4 or 5 ms.

In the surround operation modes, playback via the speakers that have been set like this is

now slightly delayed compared with the front speakers. Please determine the setting that is

optimal for your situation by changing the different parameters.

Dynamic compression

Using the DYNAMIC key, you can set the dynamic compression of the sound. By

“Dynamic”, we mean the difference in volume between very loud and very quiet passages,

that means between explosions and whispering e.g. if you have sensible neighbours or if

you like to watch action films during the night, you should set a preferably high compression

(DRC = 4/4). With the setting DRC = 0/4, you receive full dynamic. Simply press the

DYNAMIC key repeatedly. The respectively set value is shown in the display.

Tipp:

For programme sources in DTS-format, no dynamic compression is possible.

Test tone

Using the test tone, you can determine the volume proportion of the single speakers to each

other in Dolby Digital or Dolby Pro Logic II operation. Once the found balance is set, you

don’t have to change it again unless you change the position of the speaker boxes.

1. Set the normal overall volume.

2. Press the TEST TONE key repeatedly. Now, each speaker reproduces the test tone

alone, one after another, and you can control its volume using the VOL +/- keys. The

speaker that is currently active is shown in the display. It is the goal to set a volume in all

speaker channels that you consider as being almost equal.

Tip:

You have to call every speaker; only then are the settings saved.

Adjusting channels during operation

If you prefer adjusting the volume proportion of the single speakers using the audio signals

during operation, press the CH SELECT key. “L 0 DB” appears in the display. You can now

increase or decrease the volume of the left front speaker by +/- 10 dB using the VOL +/-

keys. Press the CH SELECT key again to set all remaining speakers accordingly.

LFE Trim

If you reproduce a Dolby Digital or DTS 5.1 signal via one of the digital inputs,

“LFE” appears in the display. Press now the LFE TRIM key on the remote

control. Using the VOL +/- keys, you can now decrease the volume of the

low-frequency effect channel by up to –10dB. (If you don’t press any key for

5 seconds, the device exits the LFE TRIM setting.).

Available surround modes

The surround functions create a live atmosphere in your living room that you can otherwise

only experience in cinemas, stadiums and concert halls.

Select the appropriate surround mode according to the programme source. Please keep in

mind that all surround speakers must be connected so that you are able to enjoy the DTS,

DOLBY DIGITAL, Dolby Pro Logic surround functions. We recommend using the center

speaker for the DTS, DOLBY DIGITAL, Dolby Pro Logic surround operation.

Press the DOLBY DIGITAL key if the programme reaches the receiver via the digital inputs.

Only the digital connection transmits the encoded digital data.

Activate the DOLBY PRO LOGIC or DTS operation if you operate the device in analogue

mode. If a signal in Dolby Digital format is present, the surround mode switches to DOLBY

DIGITAL automatically.

DTS Digital Surround Mode

This device is equipped with the DTS Surround Mode. This mode

enables you to enjoy 5.1 (=6) different output channels with

high-quality digital signals bearing the DTS-brand, as well as DVDs,

Compact Discs etc. This leads to an extraordinarily transparent

stereoscopic sound experience of real 360°. Thus, DTS-programmes

should always be reproduced in DTS-mode. (DTS is a trademark of

DTS Technology, LLC. Produced under licence of the DTS Technology,

LLC.)

DOLBY DIGITAL Mode

This operation mode, as well, enables you to enjoy 5.1 (=6) different

output channels with digital surround sound from Dolby Digital

programme sources.

If you connect a DVD-player with a DOLBY DIGITAL output to the digital input (coaxial or

optical) of your surround receiver and if you play a correspondingly encoded disc, you will

experience excellent sound quality, accurate spatial representation and an optimal dynamic

range. This results from 5 independent audio channels with full frequency range as well as a

subwoofer channel that is called “LFE” (Low Frequency-only Effects channel). This

3-dimensional reproduction of the sound in the room with all its movements and relative

positions is reached by the complete independence of the 6 audio channels from each other.

In this way you are presented surprisingly real and impressive sceneries.

Some Dolby Digital programmes contain information that allows you to compress the

dynamic range of the soundtrack without compromising the sound quality. This results in

“softer” sound effects that are possibly appropriate if you want to watch movies late at

night. You will find more information on the dynamic function on page 17.

Radio operation

Your AV-receiver is equipped with a high-quality FM / medium wave (AM)

receiver with RDS-function. RDS (Radio Data System) is a system for the

additional information transmittal with the FM-radio programme. RDS

radio tuners are able to filter this information out of the transmitted signal

and make it useful for different functions, e.g. for showing the station’s

name in the display or for searching for stations with certain programme

contents. Not all FM-stations transmit RDS-information.

Searching for channels

1. Press the TUNER/BAND key at the device or the TUNER key of the

remote control. In the display, the abbreviation of the frequency band (FM

or AM) as well as the currently set receiving frequency appears.

2. In order to switch to the other frequency band, press the TUNER/BAND key

at the device or the BAND key of the remote control again.

3. Using the AUTO/MANUAL key of the remote control, you can switch

between manual and automatic channel search.

In automatic channel search (= “AUTO” can be seen in the display), press

the TUNING + or – key slightly in order to make the device search for

the next channel having a higher or lower frequency and a sufficiently

strong signal. Then the search stops and the found channel is played. In

manual channel search, you press the TUNING + or – key repeatedly in

order to change the receiving frequency upwards or downwards and to

adjust the desired channel.

Tip:

This procedure lends itself if the signal of the desired channel is not strong enough

for being perceived by the automatic channel search.

4. Press the STEREO key at the device or the ST/MONO key of the remote

control during FM-operation in order to switch between stereo and mono

operation. In stereo operation, the stereo sign “ ” is illuminated in the

display.

Tipp:

If the reception of a FM-stereo programme appears to be too noisy, switch to mono

in order to reduce the noise.

Storing channels

Your AV-R500 has 15 presets for FM and 15 presets for AM that you can occupy

automatically or manually with your preferred channels.

Automatic channel storing

1. Choose the desired frequency band – FM or AM.

2. Then press the APS key so that the device automatically saves the 15

channels with the strongest reception on the presets.

Manual channel storing

1. Choose the desired frequency band – FM or AM.

2. Set the first channel that you want to save.
