incoming signal, only a limited number of surround modes are available. Although there is never a time when all of the AVR 354’s surround modes are available, there is usually a wide variety of modes available for a given input.
Multichannel digital recordings usually are found in the

or 96kHz, and 5.1 or 7.1 multichannel PCM.
When a digital signal is received, the AVR 354 detects the encoding method and the number of channels. The number of channels encoded will appear briefly in the
The first number indicates the number of front channels in the signal:
“1” represents a monophonic recording, usually an older program that has been digitally remastered or, more rarely, a modern program for which the director has chosen a special effect.
“2” indicates the presence of the left and right channels, but no center channel.
“3” indicates that all three front channels (left, right and center) are present.
The second number indicates whether any surround channels are present:
“0” indicates that no surround information is present.
“1” indicates that a matrixed surround signal is present.
“2” indicates discrete left and right surround channels.
“3” is used with
“4” is used with
The third number is used for the LFE channel:
“0” indicates no LFE channel.
“.1” indicates that an LFE channel is present.

When a PCM signal is received, the PCM message, followed by the sampling rate of the signal (32kHz, 44.1kHz, 48kHz or 96kHz), will appear in the
In addition, the Speaker/Channel Input Indicators will indicate the number of channels discretely encoded in the signal by displaying a letter inside that channel’s speaker box. A line will connect the SBL and SBR boxes when a

When only two channels – left and right – are present, the analog surround modes may be used to decode the signal into the remaining channels.
If you would prefer a different surround format than the native signal’s digital encoding, press the Surround Modes Button to display the Surround Modes menu (see Figure 62).
The Auto Select option (the first line) uses the native signal’s digital encoding, e.g., Dolby Digital or DTS. For
Each line is set to a default surround mode:
•Virtual Surround: Dolby Virtual Speaker Reference
•Stereo:
•Movie: Logic 7 Movie
•Music: Logic 7 Music
•Video Game: Logic 7 Game
You may change each line’s setting to a different surround mode. The choice of new modes depends on the number of speakers in your system.
•Virtual Surround: Dolby Virtual Speaker Reference or Wide
