Choosing the input signal

You need to hook up a component to both analog and digital inputs on the receiver to select between input

The table below indicates when you will hear the surround back channel when playing various kinds of sources. ( =Sound plays through surround back speaker(s))

signals.1

STATUS	SIGNAL SEL	SBch	STEREO
MULTI OPE	THX	STANDARD	ADV.SURR

SHIFT PHASE MCACC S.DIRECT

RECEIVER

•Press SIGNAL SEL (SIGNAL SELECT) to select the input signal corresponding to the source component. Each press cycles through the options as follows:

•AUTO – This is the default setting. The receiver selects the first available signal in the following order: DIGITAL; ANALOG.

•ANALOG – Selects an analog signal.

•DIGITAL – Selects an optical or coaxial digital signal.

•HDMI – Selects an HDMI signal.2

•PCM – Only PCM signals are output.3

When set to DIGITAL or AUTO, 2 DIGITAL lights with Dolby Digital decoding, DTS lights with DTS decoding, and WMA9 Pro lights to indicate decoding of a WMA9 Pro signal.

Using surround back channel processing

• Default setting: SBch ON

You can have the receiver automatically use 6.1 or 7.1 decoding for 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES), or you can choose to always use

6.1or 7.1 decoding (for example, with 5.1 encoded

material). With 5.1 encoded sources, a surround back channel will be generated, but the material may sound better in the 5.1 format for which it was originally encoded (in which case, you can simply switch surround back channel processing off).

STATUS	SIGNAL SEL	SBch	STEREO
MULTI OPE	THX	STANDARD	ADV.SURR

SHIFT PHASE MCACC S.DIRECT

RECEIVER

•Press SBch (SBch PROCESSING) repeatedly to cycle the surround back channel options.

Each press cycles through the options as follows:

•SBch ON – 6.1 or 7.1 decoding is always used (for example, a surround back channel will be generated for 5.1 encoded material)

•SBch AUTO – Automatically switches to 6.1 or 7.1 decoding for 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES)

•SBch OFF – Maximum 5.1 playback

Using the Virtual Surround Back mode

When you’re not using surround back speakers, selecting this mode allows you to hear a virtual surround back channel through your surround speakers. You can choose to listen to sources with no surround back channel information, or if the material sounds better in the format (for example, 5.1) for which it was originally encoded, you can have the receiver only apply this effect

to 6.1 encoded sources like Dolby Digital EX or DTS-ES.4

The table indicates when you will hear the virtual surround back channel. ( =Virtual surround back channel is active)

•Press SBch (SBch PROCESSING) repeatedly to cycle the virtual surround back channel options.

Each press cycles through the options as follows:

•VirtualSB ON – Virtual Surround Back is always used (for example, on 5.1 encoded material)

•VirtualSB AUTO – Virtual Surround Back is automatically applied to 6.1 encoded sources (for example, Dolby Digital EX or DTS-ES)

Note

1• This receiver can only play back Dolby Digital, PCM (32 kHz to 96 kHz), DTS (including DTS 96 kHz/24 bit) and WMA9 Pro digital signal formats. With other digital signal formats, set to ANALOG (the MULTI CH IN, TUNER and iPod functions are all fixed to ANALOG).

•You may get digital noise when a LD or CD player compatible with DTS is playing an analog signal. To prevent noise, make the proper digital connec- tions (page 15) and set the signal input to DIGITAL.

•Some DVD players don’t output DTS signals. For more details, refer to the instruction manual supplied with your DVD player.

2When the HDMI option in Setting the AV options on page 61 is set to THROUGH, the sound will be heard through your TV, not from this receiver.

3• This is useful if you find there is a slight delay before AUTO recognizes the PCM signal on a CD, for instance.

•When PCM is selected, noise may be output during playback of non-PCM sources. Please select another input signal if this is a problem.

4• You can’t use the Virtual Surround Back mode with headphones, or with the THX, STEREO or Stream Direct modes.

•You can only use the Virtual Surround Back mode if the surround speakers are on and the Surr Back setting is set to NO in the Speaker Setting on page 42.

•Depending on the input signal and the listening mode, the Virtual Surround Back mode may not be effective.
