S3125A
10. Ventilation – Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the appliance and to protect it from overheating, and these openings must not be blocked or covered. The openings should never be blocked by placing the appliance on a bed, sofa, rug, or other similar surface. The appliance should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided. There should be free space of at least 20 cm (8 in.) and an opening behind the appliance.
11. Power Sources – The appliance should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your appliance dealer or local power company.
12. Grounding or Polarization – The appliance may be equipped with a polarized alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
13. Power-Cord Protection – Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
14. Outdoor Antenna Grounding – If an outside antenna or cable system is connected to the appliance, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna-discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See Figure 1.
15. Lightning – For added protection for the appliance during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the appliance due to lightning and power-line surges.
16. Power Lines – An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.
17. Overloading – Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in a risk of fire or electric shock.
18. Object and Liquid Entry – Never push objects of any kind into the appliance through openings as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any kind on the appliance.
19. Servicing – Do not attempt to service the appliance yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
20. Damage Requiring Service – Unplug the appliance form the wall outlet and refer servicing to qualified service personnel under the following conditions:
A. When the power-supply cord or plug is damaged,
B. If liquid has been spilled, or objects have fallen into the appliance,
C. If the appliance has been exposed to rain or water,
D. If the appliance does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the appliance to its normal operation,
E. If the appliance has been dropped or damaged in any way, and
F. When the appliance exhibits a distinct change in performance – this indicates a need for service.
21. Replacement Parts – When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
22. Safety Check – Upon completion of any service or repairs to the appliance, ask the service technician to perform safety checks to determine that the appliance is in proper operation condition.
23. Wall or Ceiling Mounting – The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer.
24. Heat – The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat.

Positioning speakers
This unit has two sets of speaker system terminals (for
SPEAKERS A and SPEAKERS B).
Before connecting the speakers, place them correctly by consulting the instruction manuals that came with them.
For surround playback, the configuration and placement of your speakers are very important.
Standard speaker system for reproducing surround sound
• Front right and left speakers
• Center speaker
Produces a rich sound image by serving as a sound source for the front right and left speakers and enhancing the sonic movement.
• Surround right and left speakers
Adds three-dimensional sonic movement and produces environmental sound associated with the background and effect sound for each scene.
• Subwoofer
Produces powerful and heavy bass.
Speaker placement
Ideal speaker placement varies depending on the size of your room and the wall coverings. Here, only typical example of speaker placement and recommendations are shown.
Important points regarding speaker placement
Front left and right speakers and center speaker
• Place these three speakers at the same height from the floor.
• Place each speaker so that sound is aimed at the location of the listener’s ears at the listening position.
• Install the left and right front speakers at the same distance from the listening position.
Surround left and right speakers
• Place these speakers so that their height is 1 meter (3.3 feet) higher than that of the listener’s ears.
Subwoofer
• The subwoofer can provide a similar sound effect regardless of the installation position, provided that it is installed within the room containing the listening position.
If the subwoofer and center speaker are not available
The sound recorded for the center speaker and the subwoofer will be properly distributed to the front right and left speakers for optimized surround playback.

For the front right, front left, center, surround right and surround left speakers, the output levels can be adjusted between –12 to +12 dB. The subwoofer can be adjusted between –30 to +12 dB.
The volume levels from the speakers reproducing MULTI
CHANNEL INPUT are independent from the speaker levels set using the test tone (page 21). These settings are not applied to speakers reproducing MULTI CHANNEL INPUT.
Notes:
• MULTI CH cannot be selected when FM, AM or PHONO is selected as the input source.
• The surround mode cannot be selected when MULTI CH is selected. Also, if MULTI CH is selected during use of a surround mode, it is canceled automatically.
• If the speaker level is set to +1 dB or higher, the maximum level indicated in the display will change if you raise the volume level.
• Regardless of the speaker configuration, the input signal will be output to each corresponding speaker. For example, even if the speaker configuration is set to 2 ch, sound comes from all speakers.

To enjoy Surround mode
The TX-DS494’s surround sound enables you to enjoy the presence of a movie theater or concert hall in your room.
Before using a surround mode, make sure the speaker setup has been set (refer to page 21).
The configuration of the speakers are very important for the surround sound. Refer to “Positioning speakers” on page 16 and
“Connecting speakers” on page 17.
Surround modes
DOLBY DIGITAL Surround, DTS (Digital Theater
System) Surround
This 5.1-channel digital surround format enables you to individually record and play five full-range (20 Hz-20 kHz) channels (left and right front, center, two surround channels) plus an LFE channel
(Low Frequency Effect) for the low-range effect sound. It will create a realistic sound that could be heard in the theaters and concert halls.
DOLBY DIGITAL: Select this option when you play a DVD video that has a mark.
DTS: Select this option when you play a DVD player, laser disc, or CD that has a mark.
DOLBY PRO LOGIC II surround
This is a 5-channel surround system of a new generation, casting a bridge between the previous 4-channel (Left/Right Front, Center and monaural surround channels) Pro Logic surround and 5.1channel Dolby Digital surround. Dolby Pro Logic II provides the
MOVIE mode optimized for viewing movies and the MUSIC mode optimized for listening to music. In the MOVIE mode, the surround channel, which has been monaural and based on narrow band, is reproduced in stereo so that the feeling of movement in the played movies is more enhanced. In the MUSIC mode, the surround channel reproduces natural sound field even with 2channel music sources.
The MOVIE mode allows you to enjoy VHS and DVD software carrying the marking as well as some of TV broadcast programs. The MUSIC mode allows you to enjoy stereo music from CD, etc.
Analog/PCM (Pulse Code Modulation) surround
Analog sources include the audio records, AM/FM broadcasting and cassette tapes. The PCM (Pulse Code Modulation) signal is a kind of digital audio signal, which is recorded directly on CD or
DVD without being compressed. When an analog or PCM source is played, you can enjoy unique surround modes to Onkyo as listed below.
ORCHESTRA: This mode is suitable for classics and opera music. The center channel is cut and the surround channels are emphasized to widen the stereo image. It will simulate a natural reverberation that can be created in a large hall.
UNPLUGGED: This mode is suitable for acoustic instrumental sounds, vocals, and jazz music. By emphasizing the front stereo image, it will simulate the acoustics in front of the stage.
ALL CH ST: This mode is useful for background music. The front and surround channels will create a stereo image.
Notes on DTS
• If you play a CD or LD that supports DTS when the
“ANALOG” setting is selected on the TX-DS494, the DTS encoded signal will not be decoded and noise will be output.
This noise could damage the amplifier and speakers.
Therefore, be sure to select “AUTO” and use the DIGITAL
INPUT jacks (OPTICAL/COAXIAL) to connect the DTS source. (Refer to “Setting the input signal format” on page 23.)
• If you play a CD or LD that supports DTS when the “AUTO” setting is selected, you may hear a noise for a short while until the DTS decoder recognizes the DTS encoded signal and starts operating. This is not a malfunction.
• If you press the pause or skip button on the player while playing a DTS source, a short noise may be heard. This is not a malfunction.
• The DTS indicator on the TX-DS494 lights up while it plays the DTS source. When playback concludes and the DTS signal transmission stops, the TX-DS494 remains in DTS mode and the DTS indicator remains lit. This prevents noise when you operate the pause or skip button on the player. Therefore, if the source switches from the DTS signal to the PCM signal immediately, the PCM signal may not be played. In this case, stop the playback of the source on the player for about 3 seconds, then resume playback.
• Some CD players and LD players may be unable to play DTS sources correctly even if you connect the player to the
TX-DS494 digitally. This is because the digital signal has been processed (such as the output level, sampling frequency, frequency response, etc.), and the TX-DS494 cannot recognize the signal as DTS data. Therefore, you may hear noise when you play a DTS source while processing the signal.
• The TAPE OUT or VIDEO 2 OUT jacks of the TX-DS494 output analog audio. Do not record CDs or LDs that support
DTS using these jacks. Otherwise, you will record a DTS encoded signal as noise.

Late Night function
Since the audio in movies produced for theaters has a big difference between the highest and lowest levels (dynamic range), it is sometimes necessary to increase the volume to a very high level when you want to listen to low-level audio such as environmental sounds and low human voices. In such a case, switch the Late Night function to ON to reduce the dynamic range so that even low-level audio can be identifiable without increasing the overall listening volume.
This function is especially convenient when you have to view a movie at a low volume in the night time, etc.
During Dolby Digital surround playback, press the
DSP button.
Each press of the button switches the Late Night function ON and
OFF alternately.

Pre-programming remote controller (North American models only)
Pre-programming code is only available on the RC-444M remote controller for TX-DS494 North American model.
Learning a pre-programming code
You can make RC-444M remote controller to operate a product from other brand than Onkyo by storing the pre-programming code of the brand in the RC-444M.
1. Find the 2-digit number for the brand name of the component that you want to operate in the table on page 33.
2. Turn on the component that you want to operate
(i.e. DVD, satellite tuner, or television).
3. While holding down the MODE button on the
RC-444M that you want to program, press the
LEVEL 5 button, and then release both buttons.
4. Within 30 seconds, enter the 2-digit code number.
To enable entry of the 2-digit code number, some of the remote controller keys become the numeric keys with the assignment as shown in the figure.
5. Press some operation buttons for the component that you want to operate to check if the system operates properly.
If the system operates properly, the code is correct. If the component does not operate properly, return to step 3.

Controlling a DVD player
Buttons with programmed usage and operations are the same as the operational buttons on page 31.
When entering the code of Onkyo DVD players
There are three SETTING numbers. Choose the SETTING number according to how you will be using the DVD player.
No. 02/03: These codes are for operating the Onkyo DVD player by pointing the remote controller directly at it, either because it does not have an z connector, or it does but you are not using an z cable and connecting it. First enter 02 and if it does not operate properly, enter 03.
No. 01: This code is for Onkyo DVD players that have an z connector that you are connecting to the TX-DS494 with an z cable. You will then operate the DVD player by pointing the remote controller at the remote control sensor on the TX-DS494.
You do not need to enter this code because it is factory preset.
However, if the code has been changed to 02 or 03, then you will need to change it back to 01.
