Frequently Asked Questions - AVR-981 DENON

How do I connect my TV to the Denon AVR-981?

Use an HDMI or optical cable. For video, connect the TV's output to one of the video inputs (composite, S-Video, or component) on the receiver. For audio, use an optical or coaxial digital input. Then select the corresponding input source on the receiver.

What type of speakers can I use with the AVR-981?

The receiver supports speakers with an impedance between 4 and 16 ohms. It is designed for a 5.1 surround sound setup: front left/right, center, surround left/right, and a subwoofer. Ensure the total impedance per channel is within the specified range.

How do I set up the surround sound?

Connect your speakers to the corresponding terminals (Front, Center, Surround, Subwoofer). Go to the setup menu on the front panel or via the remote, and run the auto setup or manual test tones to calibrate levels and distances. Select a surround mode like Dolby Digital or DTS from the remote.

Why is there no sound from the subwoofer?

Ensure the subwoofer is connected to the Subwoofer Pre-out jack. Check the subwoofer's power and volume. In the receiver's setup, make sure subwoofer is enabled and the crossover frequency is set appropriately (e.g., 80 Hz). Also verify that the audio source contains a low-frequency effects (LFE) channel.

Can I use the AVR-981 with a universal remote?

Yes, the AVR-981 can be programmed to work with many universal remotes. Use the remote codes from your remote's manual or search online for Denon codes (e.g., 0420, 0449). Alternatively, you can use the learning function if your universal remote supports it.

How do I reset the receiver to factory settings?

Turn off the receiver. Press and hold the POWER button and the SURROUND MODE button simultaneously until the display shows 'Clear'. Then release. This resets all settings to default. Note: this will erase any custom configurations.

The receiver turns off by itself. What’s wrong?

This may be due to overheating (ensure proper ventilation), a short circuit in speaker wires (check connections), or impedance too low. Try reducing volume, improving airflow, or disconnecting speakers one by one to isolate the issue. If persists, consult a technician.

How do I listen to music from my phone?

Connect your phone via a 3.5mm to RCA cable to one of the analog audio inputs (e.g., AUX). Alternatively, use a Bluetooth adapter plugged into an analog or digital input. Then select the corresponding input on the receiver.

What is the difference between Dolby Pro Logic II and Dolby Digital?

Dolby Digital is a lossy compression format that provides up to 5.1 discrete channels, commonly used in DVDs and streaming. Dolby Pro Logic II is a matrix decoding technology that creates surround sound from stereo sources (like TV or music) and can also decode 5.1 from 2-channel material. The AVR-981 supports both.

Where can I find the user manual for the AVR-981?

You can download the manual in PDF format from notice-facile.com or the Denon support website. Search for 'AVR-981 manual' and choose your language. The manual includes detailed instructions on setup, operation, and troubleshooting.

3 CAUTIONS ON HANDLING

- Switching the input function when input jacks are not connected

A clicking noise may be produced if the input function is switched when nothing is connected to the input jacks. If this happens, either turn down the MASTER VOLUME control or connect components to the input jacks.

- Muting of PRE OUT jacks, HEADPHONE jack and SPEAKER terminals

The PRE OUT jacks, HEADPHONE jacks and SPEAKER terminals include a muting circuit. Because of this, the output signals are greatly reduced for several seconds after the power switch is turned on or input function, surround mode or any other-set-up is changed. If the volume is turned up during this time, the output will be very high after the muting circuit stops functioning. Always wait until the muting circuit turns off before adjusting the volume.

Note to CATV system installer:

This reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC which provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

Notes:

- Do not connect two FM antennas simultaneously.

• Even if an external AM antenna is used, do not disconnect the AM loop antenna.
• Make sure AM loop antenna lead terminals do not touch metal parts of the panel.

Connecting the external input (EXT. IN) jacks

• These input jacks are for inputting multi-channel audio signals in high definition MUSE 3-1 format, multi-channel audio signals from an MPEG multi-channel decoder, or future multi-channel sound format, etc.
• When making connections, also refer to the operating instructions of the other components.

When connecting a high definition (MUSE 3-1 format) component, use a separately sold mono/stereo cable if the surround channel output is monaural.

Monaural. Front Surround Subwoofer Center LINE OUT

Decoders with 6-channel analog outputs, etc.

Speaker system connections

• Connect the speaker terminals with the speakers making sure that like polarities are matched ( with , with ). Mismatching of polarities will result in weak central sound, unclear orientation of the various instruments, and the sense of direction of the stereo being impaired.
• When making connections, take care that none of the individual conductors of the speaker cord come in contact with adjacent terminals, with other speaker cord conductors, or with the rear panel.

NOTE: NEVER touch the speaker terminals when the power is on. Doing so could result in electric shocks.

Speaker Impedance

• Speakers with an impedance of from 6 to 16 /ohms can be connected for use as surround and center speakers.
• Speakers with an impedance of 6 to 16/ ohms can be connected for use as front speakers.
• Be careful when using two pairs of front speakers (A + B) at the same time, since use of speakers with an impedance of less than 8 Ω/ohms will lead to damage.
• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower than the specified impedance are connected.

• Precautions when connecting speakers

If a speaker is placed near a TV or video monitor, the colors on the screen may be disturbed by the speaker's magnetism. If this should happen, move the speaker away to a position where it does not have this effect.

Protector circuit

- This unit is equipped with a high-speed protection circuit. The purpose of this circuit is to protect the speakers under circumstances such as when the output of the power amplifier is inadvertently short-circuited and a large current flows, when the temperature surrounding the unit becomes unusually high, or when the unit is used at high output over a long period which results in an extreme temperature rise.

When the protection circuit is activated, the speaker output is cut off and the power supply indicator LED flashes. Should this occur, please follow these steps: be sure to switch off the power of this unit, check whether there are any faults with the wiring of the speaker cables or input cables, and wait for the unit to cool down if it is very hot. Improve the ventilation condition around the unit and switch the power back on.

If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around the unit, switch off the power and contact a DENON service center.

Note on speaker impedance

- The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower than the specified impedance (for example speakers with an impedance of lower than 4 Ω/ohms) are connected. If the protector circuit is activated, the speaker output is cut off. Turn off the set's power, wait for the set to cool down, improve the ventilation around the set, then turn the power back on.

NOTES:

• The on-screen display signals are output with priority to the S-VIDEO MONITOR OUT jack during playback of a video component. For example, if the TV monitor is connected to both the AVR-2801/981's S-Video and video monitor output jacks and signals are input to the AVR-2801/981 from a video source (VDP, etc.) connected to both the S-Video and video input jacks, the on-screen display signals are output with priority to the S-Video monitor output. If you wish to output the signals to the video monitor output jack, do not connect a cord to the S-VIDEO MONITOR OUT jack. (For details, see page 22.)
• The AVR-2801/981's on-screen display function is designed for use with high resolution monitor TVs, so it may be difficult to read small characters on TVs with small screens or low resolutions.
• The setup menu is not displayed when "HEADPHONE ONLY" is selected.

Enter the setting.

When "Front" is set to "Large" and "Subwoofer" is set to "Yes" the set switches to the subwoofer mode.

NOTE:

- Select "Large" or "Small" not according to the actual size of the speaker but according to the speaker's capacity for playing low frequency (approximately 80 Hz and below) signals. If you do not know, try comparing the sound at both settings (setting the volume to a level low enough so as not to damage the speakers) to determine the proper setting.

- Parameters

Large..... Select this when using speakers that can fully reproduce low sounds of below 80 Hz.

Small..... Select this when using speakers that cannot reproduce low sounds of below 80 Hz with sufficient volume.

When this setting is selected, low frequencies of below 80 Hz are assigned to the subwoofer.

None..... Select this when no speakers are installed.

Yes/No.... Select "Yes" when a subwoofer is installed, "No" when a subwoofer is not installed.

* If the subwoofer has sufficient low frequency playback capacity, good sound can be achieved even when "Small" is set for the front, center and surround speakers.

* For the majority of speaker system configurations, using the SMALL setting for all five main speakers and Subwoofer On with a connected subwoofer will yield the best results.

Setting the subwoofer mode

1

Select the bass signal playback mode.

Subwoofer Mode LFE : LFE +Main

2

Enter the setting.

The System Setup Menu reappears.

NOTES:

• In the Subwoofer mode screen, you have the flexibility to choose how bass information is distributed to your speakers if you have large front left and right speakers and a subwoofer as part of your home theater speaker system.
• By selecting the "LFE + Main" option, you will be sending the same bass frequencies to both the front left, front right, and the subwoofer speakers simultaneously. Depending upon your room size and shape, this can create a more evenly distributed bass around the room or sometimes actually decrease the amount of bass in the room due to low frequency cancellations.
• If the "LFE" option is selected, bass from the large front left and front right speakers goes only to the front left and front right speakers. Bass going to the subwoofer comes from the LFE signal and any speakers which you have designated as "Small." This selection is preferred as it reduces the chances of bass cancellations in the room.
• Once you have positioned all of your speakers in the room, choose the option which gives you the most solid sounding bass.
• When the subwoofer is set to "Yes", bass sound is output from the subwoofer regardless of the subwoofer mode setting in surround modes other than Dolby/DTS.

Setting the delay time

Input the distances from the listening position to the speakers and set the surround delay time.

Preparations:

Measure the distances from the listening position to the speakers (L1 to L3 on the diagram at the right).

L1: Distance from center speakers to listening position

L2: Distance from front speakers to listening position

L3: Distance from rear speakers to listening position

NOTES:

• Set the center speaker so that the distance to the front speakers (left and right) or the subwoofer is the same (L2 = L1) or so that the difference in the distance (L2 - L1) is 5 feet (1.5 meters) or less.
• Set the surround speakers (left and right) so that the distance to the front speakers (left and right) or the subwoofer is the same (L2 = L3) or so that the difference in the distance (L2 - L3) is 15 feet (4.5 meters) or less.

The "Channel Level" screen reappears.

Press the ENTER button again, the "System Setup Menu" screen reappears.

* To cancel the settings, select "Level Clear" and "Yes" on the "Channel Level" screen, then make the settings again.

The level of each channel should be adjusted to 75 dB (C-weighted, slow meter mode) on a sound level meter at the listening position. If a sound level meter is not available adjust the channels by ear so the sound levels are the same. Because adjusting the subwoofer level test tone by ear is difficult, use a well known music selection and adjust for natural balance.

NOTE: When adjusting the level of an active subwoofer system, you may also need to adjust the subwoofer's own volume control.

* When you adjust the channel levels while in the SYSTEM SETUP CHANNEL LEVEL mode, the channel level adjustments made will affect ALL surround modes. Consider this mode a Master Channel Level adjustment mode.
* After you have completed the SYSTEM SETUP CHANNEL LEVEL adjustments, you can then activate the individual surround modes and adjust channel levels that will be remembered for each of those modes. Then, whenever you activate a particular surround sound mode, your preferred channel level adjustments for just that mode will be recalled. Check the instructions for adjusting channel levels within each surround mode on Page 36.
* You can adjust the channel levels for each of the following surround modes: DIRECT, STEREO, 5CH STEREO, DOLBY/DTS SURROUND, ROCK ARENA, JAZZ CLUB, VIDEO GAME, MONO MOVIE, and MATRIX.

Notes on Batteries

- Use R6P/AA batteries in the remote control unit.

• The batteries should be replaced with new ones approximately once a year, though this depends on the frequency of usage.
• Even if less than a year has passed, replace the batteries with new ones if the set does not operate even when the remote control unit is operated nearby the set.

• When inserting the batteries, be sure to do so in the proper direction, following the "⊖" and "⊖" marks in the battery compartment.
  • To prevent damage or leakage of battery fluid:

• Do not use a new battery together with an old one.

• Do not use two different types of batteries.
• Do not short-circuit, disassemble, heat or dispose of batteries in flames.

- Remove the batteries from the remote control unit when you do not plan to use it for an extended period of time.

• If the battery fluid should leak, carefully wipe the fluid off the inside of the battery compartment and insert new batteries.
• When replacing the batteries, have the new batteries ready and insert them as quickly as possible.
• The learned remote control signals may be cleared if no batteries are in the remote control unit for about 5 seconds.

The factory-installed codes are in permanent memory, however.

Using the remote control unit

Approx. 7 m/22 feet 30° 30°

• Point the remote control unit at the remote sensor on the main unit as shown on the diagram.
• The remote control unit can be used from a straight distance of approximately 7 meters/22 feet from the main unit, but this distance will be shorter if there are obstacles in the way or if the remote control unit is not pointed directly at the remote sensor.
• The remote control unit can be operated at a horizontal angle of up to 30 degrees with respect to the remote sensor.

NOTES:

• It may be difficult to operate the remote control unit if the remote sensor is exposed to direct sunlight or strong artificial light.
• Do not press buttons on the main unit and remote control unit simultaneously. Doing so may result in malfunction.
• Neon signs or other devices emitting pulse-type noise nearby may result in malfunction, so keep the set as far away from such devices as possible.

Learning function

• If your AV component is not a DENON product or it cannot be operated with the preset memory codesets, you can "teach" the AVR-2801/981's remote control to "learn" the codes from the component's original remote control.
• The buttons that can be "learned" are the CD, DECK and CDR/MD system buttons (see page 24) and the DVD, VDP, VCR and TV system buttons (see page 27). (For the CD, CDR/MD, DVD, VDP and TV, the A block buttons can also be "learned", and for the DVD and TV, the B block buttons can also be "learned".)

1 Press the USE/LEARN selector button with the tip of a pen etc., to set the learn mode. Both the START and LEARNED/TX indicators flash.

6 Once the START LED turns off and the LEARNED/TX LED lights, release the button on the other remote control unit.

The two LEDs start flashing again. Light

7 To "learn" other buttons, repeat steps 2 to 6.

8 Once the learning operation is completed, press the USE/LEARN selector button again. The two LEDs stop flashing and the learning mode is cancelled.

NOTES:

• Up to 26 codes can be "learned", but this number may be lower if the codes are long.
• If a non-learnable button is pressed or two or more buttons are pressed at once, the two LEDs will once again light when the button(s) is released.
• If the codes could not be stored, the LEARNED/TX LED does not light after the START LED turns off. For limited number of models, codes cannot be stored in RC-881.
• If the two LEDs start flashing rapidly after the START LED lights, this means that the memory is already full, and the code you have just attempted to store was not stored.
  To "learn" that code, first perform the resetting operation. (See page 31.)

Input mode selection function

Different input modes can be selected for the different input sources. The selected input modes for the separate input sources are stored in the memory.

① AUTO (auto mode)

In this mode, the types of signals being input to the digital and analog input jacks for the selected input source are detected and the program in the AVR-2801/981's surround decoder is selected automatically upon playback. This mode can be selected for all input sources other than PHONO, CDR/TAPE and TUNER. The presence or absence of digital signals is detected, the signals input to the digital input jacks are identified and decoding and playback are performed automatically in DTS, Dolby Digital or PCM (2 channel stereo) format. If no digital signal is being input, the analog input jacks are selected.

② PCM (exclusive PCM signal playback mode)
Decoding and playback are only performed when PCM signals are being input.
③ DTS (exclusive DTS signal playback mode)

Decoding and playback are only performed when DTS signals are being input.

④ ANALOG (exclusive analog audio signal playback mode)
The signals input to the analog input jacks are decoded and played.
⑤ EXT. IN (external decoder input jack selection mode)
The signals being input to the external decoder input jacks are played without passing through the surround circuitry.

NOTES:

• Note that noise will be output when CDs or LDs recorded in DTS format are played in the "PCM" (exclusive PCM signal playback) or "ANALOG" (exclusive analog audio signal playback) mode. Select the AUTO or DTS (exclusive DTS signal playback) mode when playing signals recorded in DTS from a laser disc player.
• Noise may be generated at the beginning of playback and while searching during DTS playback in the AUTO mode. If so, play in the DTS mode.
• In some rare cases noise may be generated when you preform the operation to stop playback of a DTS-CD or DTS-LD.

NOTES:

• When "Default" is selected and the cursor button is pressed, "CINEMA EQ." and "D.COMP." are automatically turned off, "LFE" is reset and the tone is set to the default value.
• With this model, Dolby Digital encoded signals can only be played in the Dolby Pro Logic, Dolby Digital, DIRECT and STEREO mode. Other surround mode buttons will not function during the Dolgy Digital signal playback.
• With this mode, DTS signals can only be played in the DTS Surround, DIRECT and STEREO mode. Other surround mode buttons will not function during the DTS signal playback.

Surround parameters 1

CINEMA EQ. (Cinema Equalizer):

The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright.

This function only works in the Dolby Pro Logic, Dolby Digital and DTS Surround modes.

D.COMP. (Dynamic Range Compression):

Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). (This only works when playing program sources recorded in Dolby Digital or DTS.) Select one of the four parameters ("OFF", "LOW", "MID" (middle) or "HI" (high)). Set to OFF for normal listening.

LFE (Low Frequency Effect):

Program source and adjustment range

1. Dolby Digital: -10 dB to 0 dB
2. DTS Surround: -10 dB to 0 dB

* When DOLBY DIGITAL encoded software is played, it is recommended that the LFE LEVEL be set to 0 dB for correct DOLBY DIGITAL playback.

* When DTS encoded movie software is played, it is recommended that the LFE LEVEL be set to 0 dB for correct DTS playback.

* When DTS encoded music software is played, it is recommended that the LFE LEVEL be set to -10 dB for correct DTS playback.

TONE:

This adjusts the tone control. (See "Surround parameters ②" on page 43 and page 44)

- The AVR-2801/981 is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal processing to synthetically recreate the sound field. One of six preset surround modes can be selected according to the program source and the parameters can be adjusted according to the conditions in the listening room to achieve a more realistic, powerful sound. These surround modes can also be used for program sources not recorded in Dolby Surround Pro Logic or Dolby Digital.

Surround modes and their features

1	ROCK ARENA	Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming from all directions.
2	JAZZ CLUB	This mode creates the sound field of a live house with a low ceiling and hard walls. This mode gives jazz a very vivid realism.
3	VIDEO GAME Use this to enjoy video game sources.
4	MATRIX	Select this to emphasize the sense of expansion for music sources recorded in stereo. Signals consisting of the difference component of the input signals (the component that provides the sense of expansion) processed for delay are output from the surround channel.
5	5CH STEREO	In this mode, the signals of the front left channel are output from the left surround channel, the signals of the front right channel are output from the right surround channel, and the same (in-phase) component of the left and right channels is output from the center channel. This mode provides all speaker surround sound, but without directional steering effects, and works with any stereo program source.
6	MONO MOVIE (NOTE 1)	Select this when watching monaural movies for a greater sense of expansion.

* Depending on the program source being played, the effect may not be very noticeable. In this case, try other surround modes, without worrying about their names, to create a sound field suited to your tastes.
NOTE 1: When playing sources recorded in monaural, the sound will be one-sided if signals are only input to one channel (left or right), so input signals to both channels. If you have a source component with only one audio output (monophonic camcorder, etc.) obtain a "Y" adaptor cable to split the mono output to two outputs, and connect to the L and R inputs.

NOTE:

Only the DIRECT mode can be used when playing PCM signals with a sampling frequency of 96 kHz (such as from DVD-Video discs that contain 24 bit, 96 kHz audio). If such signals are input during playback in one of the other surround modes, the mode automatically switches to DIRECT.

Personal Memory Plus

This set is equipped with a personal memorize function that automatically memorizes the surround modes and input modes selected for the input different sources. When the input source is switched, the modes set for that source last time it was used are automatically recalled.

* The surround parameters, tone control settings and playback level balance for the different output channels are memorized for each surround mode.

16 ADDITIONAL INFORMATION

Speaker setting examples

Here we describe a number of speaker settings for different purposes. Use these examples as guides to set up your system according to the type of speakers used and the main usage purpose.

(1) Basic setting

Use this setting if your main purpose is to listen to movie music and when using one set (two speakers) of regular single-way or two-way speakers as the surround speakers.

Front speakers Monitor Center speaker, Subwoofer 45° 120° Surround speakers

As seen from above

• Set the front speakers with their front surfaces as flush with the TV or monitor screen as possible. Set the center speaker between the front left and right speakers and no further from the listening position than the front speakers.
• Consult the owner's manual for your subwoofer for advice on placing the subwoofer within the listening room.
• If the surround speakers are direct-radiating (monopolar) then place them slightly behind and at an angle to the listening position and parallel to the walls at a position 60 to 90 centimeters (2 to 3 feet) above ear level at the prime listening position.

Front speaker Surround speaker 60 to 90 cm

As seen from the side

(2) Using diffusion type speakers for the surround speakers

For the greatest sense of surround sound envelopment, diffuse radiation speakers such as bipolar types, or dipolar types, provide a wider dispersion than is possible to obtain from a direct radiating speaker (monopolar). Place these speakers at either side of the prime listening position, mounted above ear level.

Surround

The AVR-2801/981 is equipped with a digital signal processing circuit that lets you play program sources in the surround mode to achieve the same sense of presence as in a movie theater.

Dolby Surround

(1) Dolby Digital (Dolby Surround AC-3)

Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories.

Dolby Digital consists of up to "5.1" channels - front left, front right, center, surround left, surround right, and an additional channel exclusively reserved for additional deep bass sound effects (the Low Frequency Effects - LFE - channel, also called the ".1" channel, containing bass frequencies of up to 120 Hz).

Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound information, from the lowest bass, up to the highest frequencies – 22 kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging, and Dolby Digital offers tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.

■ Dolby Digital compatible media and playback methods

Marks indicating Dolby Digital compatibility:

The following are general examples. Also refer to the player's operating instructions.

Media Dolby Digital output	jacks Playback method (reference page)
LD {VDP}	Coaxial Dolby Digital RF output jack *1	Set the input mode to “AUTO”. (Page 32)
DVD	Optical or coaxial digital output (same as for PCM) *2	Set the input mode to “AUTO”. (Page 32)
Others (satellite broadcasts, CATV, etc.)	Optical or coaxial digital output (same as for PCM)	Set the input mode to “AUTO”. (Page 32)

*1 Please use a commercially available adapter when connecting the Dolby Digital RF (AC-3RF) output jack of the LD player to the digital input jack.

Please refer to the instruction manual of the adapter when making connection.

*2 Some DVD digital outputs have the function of switching the Dolby Digital signal output method between "bit stream" and "(convert to) PCM". When playing in Dolby Digital surround on the AVR-2801/981, switch the DVD player's output mode to "bit stream". In some cases players are equipped with both "bit stream + PCM" and "PCM only" digital outputs. In this case connect the "bit stream + PCM" jacks to the AVR-2801/981.

(2) Dolby Pro Logic

Dolby Pro Logic is a multi-channel signal playback system developed by Dolby Laboratories which decodes sources recorded in Dolby Surround into four channels: front left, center, front right and surround (the surround channel is monaural, but is played through two surround speakers). Here, "sources recorded in Dolby Surround" are sources on which surround signals (three channels or more) are recorded onto two channels using Dolby Surround encoding technology. Dolby Surround recording is possible for all two-channel signal sources, including soundtracks on DVDs (*), LDs or hi-fi VCRs (for which stereo signal recording is possible), stereo FM, TV and satellite broadcasts, stereo CD, MD and analog cassette tape recordings. Sources recorded in Dolby Surround are compatible with stereo playback, so they can be played in stereo on regular stereo equipment and in surround with Dolby Pro Logic processing. (DTS and Dolby Digital require special decoders to be played.)

With Dolby Pro Logic, the signal levels of the different channels of the source recorded in Dolby Surround are monitored, channels with higher signal levels are emphasized and the level of the other channels is decreased in order to reinforce the directivity and achieve an effective surround sound.

* DVDs recorded in Dolby Surround include sources recorded in PCM and sources recorded in 2-channel Dolby Digital. For 2-channel Dolby Digital DVD sources, the DVD player's audio mode is 2-channel Dolby Digital, and the AVR-2801/981's surround mode is Dolby Pro Logic.

■ Dolby Pro Logic compatible media and playback methods

Mark indicating Dolby Pro Logic compatibility:

When playing in Dolby Pro Logic, select the input signal according to how the player is connected to the AVR-2801/981, in the same way as selecting the stereo signal (see page 20). Set the surround mode to "DOLBY SURROUND" (see page 37) to play in Dolby Pro Logic.

DTS Digital Surround

Digital Theater Surround (also called simply DTS) is a multi-channel digital signal format developed by Digital Theater Systems.

DTS offers the same "5.1" playback channels as Dolby Digital (front left, front right and center, surround left and surround right) as well as the stereo 2-channel mode. The signals for the different channels are fully independent, eliminating the risk of deterioration of sound quality due to interference between signals, crosstalk, etc.

DTS features a relatively higher bit rate as compared to Dolby Digital (1234 kbps for CDs and LDs, 1536 kbps for DVDs) so it operates with a relatively low compression rate. Because of this the amount of data is great, and when DTS playback is used in movie theaters, a separate CD-ROM synchronized with the film is played.

With LDs and DVDs, there is of course no need for an extra disc; the pictures and sound can be recorded simultaneously on the same disc, so the discs can be handled in the same way as discs with other formats.

There are also music CDs recorded in DTS. These CDs include 5.1-channel surround signals (compared to two channels on current CDs). They do not include picture data, but they offer surround playback on CD players that are equipped with digital outputs (PCM type digital output required).

DTS surround track playback offers the same intricate, grand sound as in a movie theater, right in your own listening room.

■ DTS compatible media and playback methods

Marks indicating DTS compatibility:

The following are general examples. Also refer to the player's operating instructions.

Media Dolby Digital output	jacks Playback method (reference page)
CD	Optical or coaxial digital output(same as for PCM) *2	Set the input mode to “AUTO” or “DTS” (page 37).Never set the mode to “ANALOG” or “PCM”. *1
LD (VDP)	Optical or coaxial digital output(same as for PCM) *2	Set the input mode to “AUTO” or “DTS” (page 37).Never set the mode to “ANALOG” or “PCM”. *1
DVD	Optical or coaxial digital output(same as for PCM) *3	Set the input mode to “AUTO” or “DTS” (page 37).

*1 DTS signals are recorded in the same way on CDs and LDs as PCM signals. Because of this, the un-decoded DTS signals are output as random "hissy" noise from the CD or LD player's analog outputs. If this noise is played with the amplifier set at a very high volume, it may possibly cause damage to the speakers. To avoid this, be sure to switch the input mode to "AUTO" or "DTS" before playing CDs or LDs recorded in DTS. Also, never switch the input mode to "ANALOG" or "PCM" during playback. The same holds true when playing CDs or LDs on a DVD player or LD/DVD compatible player. For DVDs, the DTS signals are recorded in a special way so this problem does not occur.
*2 The signals provided at the digital outputs of a CD or LD player may undergo some sort of internal signal processing (output level adjustment, sampling frequency conversion, etc.). In this case the DTS-encoded signals may be processed erroneously, in which case they cannot be decoded by the AVR-2801/981, or may only produce noise. Before playing DTS signals for the first time, turn down the master volume to a low level, start playing the DTS disc, then check whether the DTS indicator on the AVR-2801/981 (see page 38) lights before turning up the master volume.
*3 A DVD player with DTS-compatible digital output is required to play DTS DVDs. A DTS Digital Output logo is featured on the front panel of compatible DVD players. Recent DENON DVD player models feature DTS-compatible digital output – consult the player's owner's manual for information on configuring the digital output for DTS playback of DTS-encoded DVDs.
