(two-channel) movie and music audio into five playback channels of
full-bandwidth surround sound. A matrix surround decoding technology, Dolby
Pro Logic II detects the directional cues that occur naturally in stereo
content and uses these elements to create a five-channel surround sound
playback experience. You can choose from the following Dolby Pro Logic II
formats - Movie, Game or Music.
- Dolby Pro Logic IIx: Pro Logic IIx expands any
existing stereo- or 5.1-channel audio for a 6.1- or 7.1- channel playback,

high sound quality playback in 5.1-channels with a sampling frequency of 96
kHz and 24 bit quantization of DVD-video.
- Digital Cinema Sound (DCS): Digital Cinema Sound is the
concept name of the surround technology for home theater developed by Sony.
DCS uses the DSP (Digital Signal Processor) technology to reproduce the
sound characteristics of an actual cinema cutting studio in Hollywood. When
played at home, DCS will create a powerful theater effect that mimics the
artistic combination of sound and action as envisioned by the movie
director. The DCS soundfields used in this receiver include:
- Cinema Studio EX A: reproduces the sound
characteristics of the Sony Pictures Entertainment "Cary Grant Theater"
cinema production studio, great for watching most any type of movie
- Cinema Studio EX B: reproduces the sound
characteristics of the Sony Pictures Entertainment "Kim Novak Theater"
cinema production studio, ideal for watching science fiction or action
movies with lots of sound effects
- Cinema Studio EX C: reproduces the sound
characteristics of the Sony Pictures Entertainment scoring stage, ideal
for watching musicals or films where orchestra music is featured in the
soundtrack
- Portable: reproduces a clearer sound image from
your portable audio device; ideal for MP3 and other compressed music
- Hall: reproduces the acoustics of a classical
concert hall

300-seat live concert house
- Headphone Sound Fields: When
headphones are connected, you can select the following sound fields:
- Headphone 2CH: outputs the sound
in stereo, 2-channel sources bypass the sound field
processing, multi-channel surround formats are downmixed to 2 channels
- Headphone Direct:
outputs analog
signals with no sound field or tone processing
- Headphone Theater (Digital Cinema
Sound): allows you to experience a theater-like environment
- Multi-Channel Stereo: Outputs 2-channel left/right signals from all speakers.
- Analog Direct: The direct feature amplifies the source without any processing, only the volume
and front speaker balance adjustments are active.
- Two Channel Stereo Mode:
The 2 channel button sets the receiver to power only the front left and right
speakers, no surround and no subwoofer. Two-channel sources bypass the sound
field processing and multi-channel sources are down-mixed to 2 channels.
Surround Back Decoding: This function lets you select
the decoding mode for the surround back signals of the multi-channel input
stream. When you select "SB Auto" and the input stream contains 6.1-channel
information, the appropriate decoder is applied to decode the surround back
signal (Dolby Digital EX, DTS-ES Matrix, or DTS-ES Discrete decoder). When you
select "SB On", Dolby Digital EX is applied when the output channel is 6.1 and
Dolby Digital EX or Dolby Pro Logic IIx is applied when the output channel is
6.1. When "Off" is selected, no surround back decoding is performed.
Auto Format Direct: The Auto
Format Direct (A.F.D.) mode presents the sound as it was recorded or encoded
without adding any surround effects. When you select A.F.D. Auto, the receiver automatically
detects the type of audio signal being input (Dolby Digital, DTS, or standard
2-channel stereo) and performs the proper decoding if necessary. You can also
select Pro Logic, Pro Logic II Movie, Pro Logic II Music, Noe:6 Music, Neo:6
Cinema, or Multi Stereo to apply the appropriate decoding for movies or normal stereo sources such
as CDs. The receiver will generate a low frequency signal for
output to the subwoofer when there is no LFE signal.
Auto Calibration: The STR-DG720 is equipped with Digital
Cinema Auto Calibration Technology which uses the included microphone to
automatically check the speaker connections, adjust the speaker output levels,
and calculate the distance from each speaker to the listening position. The
microphone has an 18' cord attached that plugs into the microphone input on
front of the receiver and has a threaded insert on the bottom so it can be
mounted to a tripod.
Note: The auto calibration feature does not measure or
adjust the subwoofer level output.
Test Tone Level Adjustment: The receiver
also employs a test tone with a
frequency centered at 800Hz which allows you to adjust the speaker levels and
balance manually while listening to the audible tone from your listening position. You
can adjust speaker and the subwoofer level and the balance of just the front
speakers from left to right.

+8, Center Balance, Right +1 to +8 (17 steps)
