10-16 Audio Mode Buttons
The five buttons (10, 13, 14, 15, and 16)
select one of the Audio + Video Standard's
audio modes.
The Audio + Vid~.o Standard automatically
selects which di~al decodingformat to use,
based on the input signal it receives.
When a silent digital signal .is present, the
Audio+Video Standard will automatically
mute its output until program material
resumes and the Audio+Video Standard
identifies the correct processing mode. This
occurs while changing laser, DVD or com-
pact discs, and between tracks on a cd.
Mute protects your syste ,m by preventing the
Audio + Video ~Standard from playing back
digital data in an incorrect format. If the Audio
+ Video Standard is going to be used as a
digital to analog converter for music play-
back, this
muting may seem awkward
because the beginning of each track may be
affected. You can change the format auto-
sensing to eliminate this muting, if you wish.
To do so, switch the unit into standby. Press
the DTS button (13) on the front panel and
switch the Audio+Video Standard out of
standby to power on (operate). This will dis-
able the automatic muting feature of the
Audio+Video Standard and will alter the way
in which the automatic format sensing oper-
ates. For best results, select DTS prior to lis-
tening to any DTS encoded material and be
careful to select the proper format for each
piece of softWare played through the. digital
inputs.
To re-engage the automatic muting feature,
switch the Audio+Video Standard into stand-
by and toggle the main power switch (38)
the rear panel to the off position. When. you
restart your Audio + Video Standard, the
automatic muting feature will be active. Be
sure to turn all amplifiers off when switching
the main power switch on and off.
