Enjoying Dolby Digital and DTS surround sound

(A.F.D. mode)

The A.F.D. (Auto Format Direct) mode allows you to listen to higher fidelity sound and select the decoding mode for listening to a 2 channel stereo sound as multi-channel sound.

A.F.D.

Press A.F.D. repeatedly to select the sound field you want.

For details, see “Type of A.F.D. mode” (page 73).

You can also select “A.F.D.” in the Sur Settings menu. For details, see “Settings for the surround sound (Sur Settings menu)” (page 61).

Notes

•This function does not work in the following cases.

–MULTI IN is selected.

–Input signals of which the sampling frequency is more than 48 kHz are being received.

–The multi-channel PCM signals are received via an HDMI IN jack.

•If you set up the sound field during DTS 96/24 signal reception, it will play back only at 48 kHz.

•NEURAL SURROUND is activated as a PCM signal of which the sampling frequency is less than 48 kHz or a 2 channel analog signal. The NEURAL SURROUND processing will be turned off automatically when another type of signal is input. The beginning of the sound may be dropped out when the SURROUND processing is turned on/off.

Tips

•We usually recommend “A.F.D. AUTO,” however sometimes it may be better to use “SB DECODING” (page 62) to match the input stream to the mode you prefer.

•You can identify the encoding format of DVD software, etc., by looking at the logo on the package.

– : Dolby Digital discs

– : Dolby Surround encoded programs

– : DTS Digital Surround encoded programs

•Only Dolby Pro Logic IIx decoding is effective, when a multi-channel signal is input.

At this time, the setup of “SB DECODING” and “SB DEC MODE” in the Sur Settings menu becomes invalid. When you select decoding modes other than Dolby Pro Logic IIx, multi-channel sound (being encoded) is output.

If you connect a sub woofer

This receiver will generate a low frequency signal for output to the sub woofer when there is no L.F.E. signal, which is a low-pass sound effect output from a sub woofer to a 2 channel signal. However, the low frequency signal is not generated for “Neo:6 Cinema” or “Neo:6 Music” when all speakers are set to “LARGE.”
