Each of the four Movie modes is slightly different, and the
best way to find if one of them suits your taste, the
recording and the specific acoustic conditions of your
listening room is to try them all, using Dolby Pro Logic as
a baseline for comparison. Nothing will be “hurt” or
damaged by trying the different modes.

Similar is with all four Music modes, but feeding each
Center signal to both left and right Front speakers. Thus
the Center channel is not used in these modes.

Applicable Mode Groups: The Movie modes are available
only in the Movie mode group, the Music modes only in
the Music mode group.

NOTE: The Movie and Music modes are available only
when an analog or PCM digital source is playing. If you
attempt to select one of these modes when a Dolby
Digital source is playing, the front panel 

will flash to remind you of the mismatch. At the

same time, the 2.0 will automatically select an appropriate
mode. The suggested mode may be identified by pressing

x

and viewing the on-screen display.

When you are playing an older monaural recording or
movie and wish to listen to it in its pure state without any
enhancement or processing, select Mono. This mode will
combine all audio channels and send them to the center
channel speaker only. Moreover it will turn the tuner to
mono receiving only.

Applicable Mode Groups: The Mono mode is accessible by
pressing the 

mode group button until the 

M o n o

mode name appears in the 

and on-

screen status reports.

The Stereo mode activates a Smart Stereo circuit to
calculate which type of stereo is best suited to the current
input source. Regardless of the input, pressing 
the 

mode group button 

y

will combine all

available input channels and funnel them into the front
left and right speakers only.

Smart Stereo is an intelligent agent that looks at the 
input signal, and creates the stereo sound from Dolby
Digital, PCM Digital stereo or analog stereo without 
any further intervention.

When an analog input is selected and 

y

is

pressed, the 2.0 turns off all digital signal processing for
the cleanest possible sound. This is a unique feature of the
2.0, rarely found even in high-end audio equipment.

Applicable Mode Groups: The Stereo mode is accessible
only by the 

button. Since Stereo is the only mode

available in this group, the 

button acts as a toggle

on/off selector. One press of the button will put the 2.0 in
the Stereo mode, and the next press returns you to the
previously selected mode.

Playing a single-channel, monaural recording does not
mean that you have to sacrifice availability of surround
sound. The Mono + mode is NOT a single-channel mode,
but rather a specially designed surround mode that takes
incoming signals and creates a multichannel audio
presentation. Through the magic of the 2.0’s processing
circuits, one channel becomes five. If you wish 
to play a selection in single-channel “true” mono, choose
the Mono mode, which may be accessed by pressing the

mode group button 

y

until the 

Mono

mode

name appears in the front panel 

and

the on-screen status messages.

The Mono + mode is only available when analog or PCM
Stereo input source is selected. Pressing the 

button when a Dolby Digital source is playing

selects the Dolby Digital Mono mode, a “true mono”
mode which is described above. Mono + is not available
when a Dolby Digital source is selected.

Applicable Mode Groups: The Mono + or Dolby Digital
Mono modes are accessible only by pressing 

.

Since either is the only mode available in this group,

acts as a toggle on/off selector. One press of the

button will put the 2.0 in the 

mode, and the next

press returns you to the previously selected mode.
