Dsp Surround Simulation - Denon avr-2105 Operating Instructions Manual

ENGLISH
Surround parameters w
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
same contents are set for all operating 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):
This sets the level of the LFE (Low Frequency Effect) sounds included in the source when playing program
sources recorded in Dolby Digital or DTS.
If the sound produced from the subwoofer sounds distorted due to the LFE signals when playing Dolby Digital
or DTS sources when the peak limiter is turned off with the subwoofer peak limit level setting (system setup
menu), adjust the level as necessary.
Program source and adjustment range:
1. Dolby Digital: –10 dB to 0 dB
2. DTS Surround: –10 dB to 0 dB
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. This can be set individually for the separate shroud mode other than Direct
mode.
SB CH OUT (Surround Back):
(1) (Multi channel source)
"OFF" ......................Playback is conducted without using the surround back speaker.
"NON MTRX" ..........The same signals those of the surround channels are output from the surround back
channels.
"MTRX ON".............Surround back channel is reproduced using digital matrix processing.
"ES MTRX"..............When playing DTS signals, the surround back signals undergo digital matrix
processing for playback.
"ES DSCRT" ............When a signal identifying the source as a discrete 6.1-channel source is included in
the DTS signals, the surround back signals included in the source are played.
II
"PL x Cinema" ......Processing is performed with the Cinema mode of the PL
Surround Back channel is reproduced.
"PL II x Music" ........Processing is performed with the Music mode of the PL
Surround Back channel is reproduced.
(2) (2ch source)
"OFF" ......................Playback is conducted without using the surround back speaker.
"ON"........................Playback is conducted using the surround back speaker.
NOTE: This operation can be performed directly using the SURROUND BACK button on the main unit's panel.

DSP SURROUND SIMULATION

• This unit is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal
processing to synthetically recreate the sound field. One of 7 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.
Surround modes and their features
The front left channel signals are output to the surround and surround back signal
5CH/7CH left channels, the front right channel signals are output to the surround and
1
STEREO surround back signal right channels, and the in-phase component of the left and
right channels is output to the center channel. Use this mode to enjoy stereo sound.
MONO MOVIE
2 Select this when watching monaural movies for a greater sense of expansion.
(NOTE 1)
Use this mode to achieve the feeling of a live concert in an arena with reflected
3 ROCK ARENA
sounds coming from all directions.
This mode creates the sound field of a live house with a low ceiling and hard walls.
4 JAZZ CLUB
This mode gives jazz a very vivid realism.
5 VIDEO GAME Use this to enjoy video game sources.
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
6 MATRIX
component that provides the sense of expansion) processed for delay are output
from the surround channel.
Select this mode to enjoy a virtual sound field, produced from the front 2-channel
7 VIRTUAL
speakers or headphones.
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" adapter cable to split the mono output to two
outputs, and connect to the L and R inputs.
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.
