Enjoying Surround Sound

Automatically decoding

the input audio signal

(AUTO DECODING)

In this mode, the receiver automatically detects the type of audio signal being input (Dolby Digital, DTS, standard 2 channel stereo, etc) and performs the proper decoding if necessary. This mode presents the sound as it was recorded/encoded, without adding any surround effects.

If you connect an active sub woofer

When the audio signal is 2 channel stereo or if the source signal does not include a LFE signal, the receiver generates a low frequency signal for output to the sub woofer.

Press AUTO DEC.

“AUTO DECODING” appears in the display and the receiver switches to the AUTO DECODING mode.

Tip

In most cases AUTO DECODING provides the most appropriate decoding. However, when playing software encoded in the Dolby Digital EX format, you may want to use SURR BACK DECODING (page 39) to match the input stream to the mode you prefer.

Using only the front

speakers

In this mode, the receiver outputs the sound from the front L/R speakers only. There is no sound from the sub woofer.

“2CH STEREO” appears in the display and the receiver switches to the 2CH STEREO mode.

Note

No sound is output from the sub woofer in the

2CH STEREO mode. To listen to the 2 channel stereo sources using the front L/R speakers and a sub woofer, set to the AUTO DECODING mode.
