Theater; Active Speaker Chart - Sony STR-DE845 Training Manual

Theater

There are four theater sound fields:
1) Night theater: Retains theater-like sound characteristics while listening at a low volume level, ideal for
late night movie viewing.
2) Mono Movie: Creates theater-like sound characteristics from movies with mono soundtracks.
3) Stereo Movie: Creates theater-like sound characteristics from movies with stereo soundtracks.
4) Headphone theater: Retains theater-like sound characteristics while listening through a pair of
headphones.
NOTE: Mono Movie and Stereo Movie modes do not convert input signals to Mono or Stereo signals.
They are strictly used for optimal playback of analog 2ch movie soundtracks.
Music
Nine different sound fields reproduce the acoustical characteristics of nine different venues. Each one of these
sound fields is designed for a 2-channel stereo input (e.g. from a CD, DAT, TV Broadcast, etc.). Some of these
sound fields are designed to perform better with certain types of music (e.g. Jazz Club with Jazz, Rock music
with Live House and so on). These sound fields are listed below:
Small Hall
Large Hall
Opera House
Jazz Club
Disco Club
Video Games
Game: This sound field is designed to be used with video game software and a stereo input. This mode will
produce dynamic audio while playing video games.

Active Speaker Chart

With so many sound fields and software formats, it can be very difficult to know which speakers are active (actual
audio applied to them by the receiver) for the software while in a particular sound field mode. Chart 2-1 on the
following page shows Sound Fields on its vertical axis and Software Formats on the top horizontal axis. It
indicates which speakers are active with the chosen Sound Field and Software Format. This chart also indicates
when Virtual Speakers are present. To get the same results as this chart at any location, the following conditions
must be met:
Conditions
1) The input device (e.g. DVD, CD etc.) must be set up properly to output the desired Software Format (e.g.
AC-3, DTS etc.).
2) The proper input on the receiver must be used to receive the desired Software format.
a. Optical and Coax Inputs: Dolby Digital (AC-3), DTS, Dolby Prologic, Dolby Surround and PCM
b. Analog Inputs: Dolby Prologic, Dolby Surround, Stereo and Mono
c. 5.1 Channel Input: This input bypasses all surround sound processing of the receiver. Note:
This is a good input to use to test if all the speakers in the system are receiving audio. The
input device must have a 5.1 Channel output.
