Notes on speaker system hookup

  • Twist the stripped ends of the speaker cords about 15mm (2/3 inch). Be sure to match the speaker cord to the appropriate terminal on the components: + to + and - to -. If the cords are reversed, the sound will be distorted and will lack bass.
  • If you use front speakers with low maximum input rating, adjust the volume carefully to avoid excessive output on the speakers.
  • The WIRELESS REAR SPEAKER jack is for use with Sony wireless rear speaker systems only, do not connect any other speaker systems or components to this jack.

Speaker System Hookup

Speaker impedance

To enjoy multi channel surround, connect front, center, and rear speakers with a nominal impedance of 8 ohms or higher, and set the speaker IMPEDANCE SELECTOR to "8Ω." Check the instruction manual supplied with your speakers if you're not sure of their impedance. (This information is usually printed on a label on the back of the speaker.)

You may connect a pair of speakers with a nominal impedance between 4 and 8 ohms to the FRONT SPEAKERS terminals, if you set the IMPEDANCE SELECTOR to "4Ω" but you will not be able to enjoy multi-channel surround sound.

Note

Be sure to connect front speakers with a nominal impedance of 8 ohms or higher if you want to select both sets (A + B) of front speakers (see page 23).

Multi-Channel Surround Setup

For the best possible surround sound all speakers should be the same distance from the listening position (A). (However, this unit lets you to place the center speaker up to 1.5 meters (5 feet) closer (B) and the rear speakers up to 4.5 meters (15 feet) closer (C) to the listening position. The front speakers can be placed from 1.0 to 12.0 meters (3 to 40 feet) from the listening position (A).)

SONY STRDE925 - Multi-Channel Surround Setup - 1

Note

Do not place the center or rear speakers farther away from the listening position than the front speakers.

Depending on the shape of your room (etc.), you may wish to place the rear speakers behind you instead of on the side walls. One advantage of this placement is that you can use a pair of large floor standing speakers matching your front speakers.

SONY STRDE925 - Note - 1

Note

If you place the rear speakers behind you, be sure to check the speaker location setting in the SPEAKER SETUP menu when using sound fields from the VIRTUAL 3D genre (see pages 16 and 28~29 for details).

Specifying the speaker types

1 Press I/O to turn on the receiver.
2 Press SET UP to display "SPEAKER SETUP".
3 Press the cursor buttons ( ) to select the parameter you want to adjust.
4 Press the cursor buttons ( ) to select setting you desire. The setting is entered automatically.
5 Repeat steps 3 and 4 until you have set all of the parameters that follow.

■ Front speaker size (FRONT)

Initial setting : LARGE

  • If you connect large speakers that will effectively reproduce bass frequencies, select "LARGE". Normally, select "LARGE".
  • If the sound is distorted, or you feel a lack of surround effects when using multi-channel surround sound, select "SMALL" to activate the bass redirection circuitry and output the front channel bass frequencies from the subwoofer.
  • When the front speaker is set to "SMALL", the center and rear speakers are also automatically set to "SMALL" (unless previously set to "NO").

Center speaker size (CENTER)

Initial setting : LARGE

  • If you connect a large speaker that will effectively reproduce bass frequencies, select "LARGE". Normally, select "LARGE". However, if the front speakers are set to "SMALL", you cannot set the center speaker to "LARGE".
  • If the sound is distorted, or you feel a lack of surround effects when using multi-channel surround sound, select "SMALL" to activate the bass redirection circuitry and output the center channel bass frequencies from the front speakers (if set to "LARGE") or subwoofer.
  • If you do not connect the center speaker, select "NO". The sound of the center channel will be output from the front speakers.

Rear speaker size (REAR)

Initial setting: LARGE

  • If you connect large speakers that will effectively reproduce bass frequencies, select "LARGE". Normally, select "LARGE". However, if the front speakers are set to "SMALL", you cannot set the rear speakers to "LARGE".
  • If the sound is distorted, or you feel a lack of surround effects when using multi-channel surround sound, select "SMALL" to activate the bass redirection circuitry and output the rear channel bass frequencies from the subwoofer or other "LARGE" speakers.

SONY STRDE925 - Rear speaker size (REAR) - 1

About speaker sizes (LARGE and SMALL)

Internally, the LARGE and SMALL settings for each speaker determine whether or not the internal sound processor will cut the bass signal from that channel. When the bass is cut from a channel, the bass redirection circuitry sends the corresponding bass frequencies to the subwoofer or other "LARGE" speaker. However, since bass sounds have a certain amount of directionality it best not to cut them, if possible. Therefore, even when using small speakers, you can set them to "LARGE" if you want to output the bass frequencies from that speaker. On the other hand, if you are using a large speaker, but prefer not to have bass frequencies output from that speaker, set it to "SMALL".

If the overall sound level is lower than you prefer, set all speakers to "LARGE". If there is not enough bass, you can use the equalizer to boost the bass levels. To set the equalizer, see page 34.

Rear speaker position (REAR PL.)*

Initial setting: BEHIND

This parameter lets you specify the location of your rear speakers for proper implementation of the Digital Cinema Sound surround modes in the VIRTUAL 3D genre. Refer to the illustration below.

  • Select "SIDE" if the location of your rear speakers corresponds to section A.
  • Select "MIDDLE" if the location of your rear speakers corresponds to section ⑥.
  • Select "BEHIND" if the location of your rear speakers corresponds to section ⑥.

This setting only effects the surround modes in the VIRTUAL 3D genre.

SONY STRDE925 - Rear speaker position (REAR PL.)* - 1

Rear speaker height (REAR HGT.)*

Initial setting : LOW

This parameter lets you specify the height of your rear speakers for proper implementation of the Digital Cinema Sound surround modes in the VIRTUAL 3D genre. Refer to the illustration below.

  • Select "LOW" if the location of your rear speakers corresponds to section A.
  • Select "HIGH" if the location of your rear speakers corresponds to section B.

This setting only effects the surround modes in the VIRTUAL 3D genre.

SONY STRDE925 - Rear speaker height (REAR HGT.)* - 1

  • These parameters are not available when "Rear speaker size (REAR)" is set to "NO".

SONY STRDE925 - Rear speaker height (REAR HGT.)* - 2

About the rear speaker position (SIDE, MIDDLE, and BEHIND)

This setting is designed specifically for implementation of the Digital Cinema Sound modes in the VIRTUAL 3D genre. With the Digital Cinema Sound modes, speaker position is not as critical as other modes. All of the modes in the VIRTUAL 3D genre were designed under the premise that the rear speaker would be located behind the listening position, but presentation remains fairly consistent even with the rear speakers positioned at a rather wide angle. However, if the speakers are pointing toward the listener from the immediate left and right of the listening position, the VIRTUAL 3D modes will not be effective unless the rear speaker position parameter is set to "SIDE". Nevertheless, each listening environment has many variables, like wall reflections, and you may obtain better results using "BEHIND" or "MIDDLE" if your speakers are located high above the listening position, even if they are to the immediate left and right.

Therefore, although it may result in a setting contrary to the "Rear speaker position" explanation, we recommend that you playback multi channel surround encoded software and listen to the effect each setting has on your listening environment. Choose the setting that provides a good sense of spaciousness and that best succeeds in forming a cohesive space between the surround sound from the rear speakers and the sound of the front speakers. If you are not sure which sounds best, select "BEHIND" and then use the speaker distance parameter and speaker level adjustments to obtain proper balance.

Sub woofer selection (WOOFER)

Initial setting: YES

  • If you connect a subwoofer, select "YES".
  • If you do not connect a subwoofer, select "NO". This activates the Dolby Digital (AC-3) bass redirection circuitry and outputs the LFE signals from other speakers.
  • In order to take full advantage of the Dolby Digital (AC-3) bass redirection circuitry, we recommend setting the sub woofer's cut off frequency as high as possible.

Specifying the speaker distances

1 Press SET UP to display "SPEAKER DISTANCE".
2 Press the cursor buttons (A) to select the parameter you want to adjust.
3 Press the cursor buttons ( ) to select setting you desire. The setting is entered automatically.
4 Repeat steps 2 and 3 until you have set all of the parameters described below.
5 Press SET UP to exit the set up mode.

■ Front speaker distance (FRONT)

Initial setting: 5.0 meter

Set the distance from your listening position to the front (left or right) speaker (A on page 14).

  • Front speaker distance can be set in 0.1 meter (1 foot) steps from 1.0 to 12.0 meters (3 to 40 feet).
  • If both speakers are not placed an equal distance from your listening position, set the distance to the closest speaker.

Center speaker distance (CENTER)

Initial setting: 5.0 meter

Set the distance from your listening position to the center speaker.

  • Center speaker distance can be set in 0.1 meter (1 foot) steps from a distance equal to the front speaker distance (A on page 14) to a distance 1.5 meters (5 feet) closer to your listening position (B on page 14).
  • Do not place the center speaker farther away from your listening position than the front speakers.

Rear speaker distance (REAR)

Initial setting: 3.5 meter

Set the distance from your listening position to the rear (left or right) speaker.

  • Rear speaker distance can be set in 0.1 meter (1 foot) steps from a distance equal to the front speaker distance (A on page 14) to a distance 4.5 meters (15 feet) closer to your listening position (C on page 14).
  • Do not place the rear speakers farther away from your listening position than the front speakers.
  • If both speakers are not placed an equal distance from your listening position, set the distance to the closest speaker.

SONY STRDE925 - Rear speaker distance (REAR) - 1

About speaker distances

This unit allows you to input the speaker position in terms of distance. However, it is not possible to set the center speaker farther away than the front speakers. Also, the center speaker can not be set more than 1.5 meters (5 feet) closer than the front speakers.

Likewise, the rear speakers can not be set farther away from the listening position than the front speakers. And they can be no more than 4.5 meters (15 feet) closer.

This is because incorrect speaker placement is not conducive to the enjoyment of surround sound.

Please note that, setting the speaker distance closer than the actual location of the speakers will cause a delay in the output of the sound from that speaker. In other words, the speaker will sound like it is farther away.

For example, setting the center speaker distance 1 2m (3-6 feet) closer than the actual speaker position will create a fairly realistic sensation of being "inside" the screen. If you cannot obtain a satisfactory surround effect because the rear speakers are too close, setting the rear speaker distance closer (shorter) than the actual distance will create a larger soundstage.

Adjusting these parameter while listening to the sound often results in much better surround sound. Give it a try!

Distance unit (DIST. UNIT)

Initial setting : METER

Lets you select either feet or meters as the unit of measure for setting distances. 1 foot corresponds to a 1 ms difference.

Adjusting the speaker volume

Use the remote while seated in your listening position to adjust the volume of each speaker.

Note

This unit incorporates a new test tone with a frequency centered at 800Hz for easier speaker volume adjustment.

1 Press I/O to turn on the receiver.

2 Press TEST TONE on the supplied remote.

You will hear the test tone from each speaker in sequence.

3 Adjust the volume level so that the volume of the test tone from each speaker sounds the same when you are in your main listening position.

  • To adjust the balance of the front right and front left speakers, use the BALANCE control on the front of the receiver.
  • To adjust the balance of the rear right and rear left speakers, use the REAR BALANCE parameter in the SURROUND cursor mode (see pages 33 and 34). (The rear balance can also be adjusted from the remote.)
  • To adjust the volume level of the center speaker, press the LEVEL CENTER + / - buttons on the remote.
  • To adjust the volume level of the rear speakers, press the LEVEL REAR + / - buttons on the remote.

4 Press TEST TONE on the remote again to turn off the test tone.

SONY STRDE925 - Press TEST TONE on the remote again to turn off the test tone. - 1

You can adjust the volume level of all speakers at the same

Rotate MASTER VOLUME on the main unit or press MASTER VOLUME + / - on the remote.

Notes

  • The rear balance, center level, and rear level are shown in the display during adjustment.
  • Although these adjustments can also be made via the front panel using the CURSOR MODE menu SURROUND parameters (when the test tone is output, the CURSOR MODE switches to the SURROUND parameters automatically), we recommend you follow the procedure described above and adjust the speaker levels from your listening position using the remote control.

SONY STRDE925 - Notes - 1

When setting the volume levels for each speaker

Let's assume that you have matched the sound levels of all the speakers using the test tone. Although this lays the foundation for high quality surround sound, it may be necessary to make further adjustments while listening to playback of actual software. This is because most software contains center and rear channels recorded at slightly lower levels than the two front channels.

When you actually playback software recorded in multi channel surround you will notice that increasing the center and rear speaker levels produces a better blend between the front and center speakers and greater cohesion between the front and rear speakers. Increasing the level of the center speaker about 1 dB, and the rear speakers about 1 2 dB is likely to produce better results.

In other words, in order to create a more cohesive soundstage with balanced dialog, we recommend that you make some adjustments while playing your software. Changes of only 1 dB can make a huge difference in the character of the soundstage.

Before You Use Your Receiver

Before turning on the receiver

Make sure that you have:

  • Turned MASTER VOLUME to the leftmost position (0).
  • Selected the appropriate front speakers (see "SPEAKERS selector" on page 23).
  • Set BALANCE to the center position.

Enjoying Surround Sound

This chapter describes how to set up the receiver to enjoy surround sound. You can enjoy multi channel surround when playing back software encoded with Dolby Digital or DTS.

You can take advantage of surround sound simply by selecting one of the receiver's pre-programmed sound modes. They bring the exciting and powerful sound of movie theaters and concert halls into your home. You can also customize the sound modes to obtain the sound you desire by changing the various surround parameters. The sound modes are divided by type into four basic groups called "genres". The following is a basic explanation of each genre. For information about the sound modes available in each genre, see page 28~30.

CINEMA

The sound modes in this genre are designed for use when playing back movie software (DVD, LD, etc.) encoded with multi channel surround sound or Dolby Pro Logic. In addition to decoding the surround sound, this genre also includes sound modes that provide the reflections and reverberation typically found in movie theaters. The sound modes in this genre have little effect on two-channel stereo sources (CD, MD, etc.).

VIRTUAL 3D

This genre contains compelling applications of the Sony Digital Cinema Sound digital signal processing technology. These sound modes shift the sound away from the actual speaker locations to simulate the presence of several "virtual" speakers. Like the CINEMA genre, this genre is most effective when playing back movie software encoded with multi channel surround sound.

MUSIC etc.

The sound modes in this genre are designed for use with standard audio sources (like CD) and TV broadcasts. These modes add reverberation to the source signal to create powerful soundfields that make you feel as if you were in a concert hall or stadium (etc.). Use the sound modes in this genre with two-channel sources and stereo broadcasts of sports programs or musical concerts.

A.F.D.

This genre contains the "Auto Format Decoding" sound mode which presents the sound exactly as it was encoded, without adding any reverberation (etc.).

To fully enjoy surround sound, you must register the number and location of you speakers. See "Multi-Channel Surround Setup" starting on page 14 to set the speaker parameters before enjoying surround sound.

SONY STRDE925 - A.F.D. - 1
CURSOR MODE

Brief descriptions of buttons used to enjoy surround sound

CURSOR MODE button: Press repeatedly to light up the SURROUND or EQUALIZER indicators to customize a sound field.

Cursor buttons ( / ) < 后 er pressing the CURSOR MODE button or SET UP button, use these buttons to make the actual setting.

GENRE button: Press to select the desired sound field group (genre).

SOUND FIELD ON/OFF button: Turns the sound field on or off.

MODE button: Press to select the specific sound field from the selected genre.

EQ ON/OFF button: Turns the equalizer on or off.

Selecting a Sound Field

You can enjoy surround sound simply by selecting one of the pre-programmed sound fields according to the program you want to listen to.

1 Press SOUND FIELD ON/OFF to turn on the sound field.

The current sound field is indicated in the display.

2 Press GENRE repeatedly to select the sound field group (genre), then press MODE repeatedly to select the sound field you want.

See the table starting from page 28 for information on each sound field.

The receiver memorizes the last sound field selected for each program source (Sound Field Link)

Whenever you select a program source, the sound field that was last applied is automatically applied again. For example, if you listen to CD with STADIUM as the sound field, change to a different program source, then return to CD, STADIUM will be applied again. With the tuner, sound fields are memorized separately for AM, FM, and all preset stations.

You can identify Dolby Surround-encoded software by looking at the packaging

Use discs with the In order to enjoy Dolby Digital (AC-3) playback you must use discs bearing this logo.

Note

When using sound fields, do not select both speaker systems (A + B) with the SPEAKERS selector.

Customizing Sound Fields

By adjusting the surround parameters and the equalization of the front and center speakers, you can customize the sound fields to suit your particular listening situation.

Once you customize a sound field, the changes are stored in memory indefinitely (unless the receiver is unplugged for about one week). You can change a customized sound field any time by making new adjustments to the parameters.

See the table on page 36 for the parameters available in each sound field.

To get the most from multi channel surround sound

Position your speakers and do the procedures described in "Multi-Channel Surround Setup" starting on page 14 before you customize a sound field.

Adjusting the surround parameters

The SURROUND menu contains parameters that let you customize various aspects of the current sound field. The settings available in this menu are stored individually for each sound field.

1 Start playing a program source encoded with multi channel surround sound.
2 Press CURSOR MODE repeatedly until the SURROUND indicator lights up.
3 Press the cursor buttons (A) to select the parameter you want to adjust.
4 Press the cursor buttons ( ) to select setting you desire. The setting is entered automatically.

EFFECT LEVEL (EFFECT)

Initial setting: (depends on sound mode)
This parameter lets you adjust the "presence" of the current digital cinema sound surround effect.

WALL TYPE (WALL)

Initial setting: midpoint When sound is reflected off soft material, such as a curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly effect the frequency response of the reflected sound. This parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (S) or harder (H) wall. The midpoint designates a neutral wall (made of wood).

REVERBERATION (REVERB)

Initial setting: midpoint Before sound reaches our ears, it is reflected (reverberated) many times between the left and right walls, ceiling, and floor. In a large room, sound takes more time to bounce from one surface to another than in a smaller room. This parameter lets you control the spacing of the early reflections to simulate a sonically larger (L) or smaller (S) room.

The reverberation can be adjusted ± 8 from S (small, -8) to L (large, +8) in 17 steps.
- The midpoint (0) designates a standard room with no adjustment.

LFE (Low Frequency Effect) MIX LEVEL (LFE MIX)

Initial setting: 0 dB

This parameter lets you attenuate the level of the LFE (Low Frequency Effect) channel output from the sub woofer without effecting the level of the bass frequencies sent to the sub woofer from the front, center or rear channels via the Dolby Digital (AC-3) bass redirection circuitry.

  • The level can be adjusted in 1 dB steps from -20 dB to 0dB (line level). 0dB outputs the full LFE signal at the mix level determined by the recording engineer.
  • Selecting MUTING mutes the sound of the LFE channel from the subwoofer. However, the low frequency sounds of the front, center, or rear speakers are output from the subwoofer according to the settings made for each speaker in the speaker setup (page 15).

Customizing Sound Fields

DYNAMIC RANGE COMPRESSOR (D.RANGE COMP)

Initial setting : OFF

Lets you compress the dynamic range of the sound track. This may be useful when you want to watch movies at low volumes late at night.

  • OFF reproduces the sound track with no compression.
  • STD reproduces the sound track with the dynamic range intended by the recording engineer.
  • 0.1 0.9 allow you to compress the dynamic range in small steps to achieve the sound you desire.
  • MAX provides a dramatic compression of the dynamic range.

Note

Dynamic range compression is not possible with DTS sources.

SONY STRDE925 - Note - 1

About the Dynamic Range Compressor

This parameter allows you to compress the dynamic range of the soundtrack based on the dynamic range information included in the Dolby Digital signal. "STD" is standard compression, but because many sources have only light compression, you may not notice much difference when using 0.1 0.9

Therefore, we recommend using the "MAX" setting. This greatly compresses the dynamic range and allows you to view movies late at night at low volumes. Unlike analog limiters, the levels are predetermined and provide a very natural compression.

REAR BALANCE (REAR)

Initial setting : center

Lets you adjust the balance between the rear left and right speakers.

  • The balance can be adjusted ± 8 dB in 1 dB steps.
  • This setting can also be adjusted directly using the supplied remote. See "Adjusting the speaker volume" (page 18).

REAR LEVEL (REAR)

Initial setting: 0 dB

Lets you adjust level of the rear (left and right) speakers.

The level can be adjusted in 1 dB steps from -10dB to +10dB .
- This setting can also be adjusted directly using the supplied remote. See "Adjusting the speaker volume" (page 18).

Initial setting: 0 dB

Lets you adjust the level of the center speaker.

The level can be adjusted in 1 dB steps from -10dB to +10dB .

SUB WOOFER LEVEL (WOOFER)

Initial setting: 0 dB

Lets you adjust the level of the sub woofer.

  • The level can be adjusted in 1 dB steps from -10 dB to +10 dB.

Adjusting the equalizer

The EQUALIZER menu lets you adjust the equalization (low, mid, and high frequencies) of the front and center speakers. The equalizer settings are stored individually for each sound field.

Receiving Broadcasts

This chapter describes how to receive FM or AM broadcasts and how to preset selected stations.

You can tune in stations on this receiver in the following ways:

Direct Tuning

You can enter a frequency of the station you want directly by using the numeric buttons (see page 38).

Automatic Tuning

If you don't know the frequency of the station you want, you can let the receiver scan all available stations in your area (see page 39).

Preset Tuning

After you have tuned in stations using Direct Tuning or Automatic Tuning, you can preset them to the receiver (see page 39). Then you can tune in any of the stations directly by entering its 2-character code (see page 40). Up to 30 FM or AM stations can be preset. The receiver will also scan all the stations that you have preset (see page 40).

Before you begin, make sure you have:

  • Connected FM and AM antennas to the receiver (see page 5).
  • Selected the appropriate speaker system (see page 23).

Glossary

Surround sound

Sound that consists of three elements: direct sound, early reflected sound (early reflections) and reverberative sound (reverberation). The acoustics of the surrounding space affect the way these three sound elements are heard. Surround sound combines these sound elements in such a way that you actually can sense the size of the venue, as well as its type.

Transition of sound from rear speakers

SONY STRDE925 - Surround sound - 2

Dolby Pro Logic Surround

As one method of decoding Dolby Surround, Dolby Pro Logic Surround produces four channels from two-channel sound. Compared with the former Dolby Surround system, Dolby Pro Logic Surround reproduces left-to-right panning more naturally and localizes sounds more precisely. To take full advantage of Dolby Pro Logic Surround, you should have one pair of rear speakers and a center speaker. The rear speakers output monaural sound.

Dolby Digital (AC-3)

This sound format for movie theaters is more advanced than Dolby Pro Logic Surround. In this format, the rear speakers output stereo sound with an expanded frequency range and a subwoofer channel for deep bass is independently provided. This format is also called "5.1" because the subwoofer channel is counted as 0.1 channel (since it functions only when a deep bass effect is needed). All six channels in this format are recorded separately to realize superior channel separation. Furthermore, since all the signals are processed digitally, less signal degradation occurs. The name "AC-3" comes from the fact that it is the third audio coding method to be developed by the Dolby Laboratories Licensing Corporation.

Digital Cinema Sound

This is the generic name of the surround sound produced by digital signal processing technology developed by Sony. Unlike previous surround sound fields mainly directed at the reproduction of music, Digital Cinema Sound is designed specifically for the enjoyment of movies.
