Multiple surround speakers
Movie theater sound field
Listening room sound field
In this case it is important to achieve the same
sense of expansion as in a movie theater with
the surround channels.
To do so, in some cases the number of
surround speakers is increased (to four or
eight) or speakers with bipolar or dipolar
properties are used.
• Other types of audio These signals are designed to recreate a 360° sound field using three to five
speakers.
In this case the speakers should surround the listener from all sides to
create a uniform sound field from 360°. Ideally the surround speakers
should function as “point” sound sources in the same way as the front
speakers.
These two types of sources thus have different properties, and different speaker settings, particularly for the
surround speakers, are required in order to achieve the ideal sound.
The AVC-A1SR’s surround speaker selection function makes it possible to change the settings according to
the combination of surround speakers being used and the surrounding environment in order to achieve the
ideal surround sound for all sources. This means that you can connect a pair of bipolar or dipolar surround
speakers (mounted on either side of the prime listening position), as well as a separate pair of direct radiating
(monopolar) speakers placed at the rear corners of the listening room.

ADDITIONAL INFORMATION
Optimum surround sound for different sources
There are currently various types of multi-channel signals (signals or formats with more than two channels).
2 Types of multi-channel signals
Dolby Digital (EX), Dolby Pro Logic, DTS (ES), high definition 3-1 signals (Japan MUSE Hi-Vision audio), DVD-
Audio, SACD (Super Audio CD), MPEG multi-channel audio, etc.
“Source” here does not refer to the type of signal (format) but the recorded content. Sources can be divided
into two major categories.
Types of sources
• Movie audio Signals created to be played in movie theaters. In general sound is recorded to be played
in movie theaters equipped with multiple surround speakers, regardless of the format
(Dolby Digital, DTS, etc.).
SL: Surround L channel
SR: Surround R channel
SB: Surround B (back) channel
