INPUT SELECT (AUTO, ANALOG, DIGITAL)
The INPUT SETUP menu allows the selection of two audio
connector types - one analog, one digital. INPUT SELECT specifies
how these connectors interact. The following settings are available:
• The DIGITAL setting forces the unit to utilize the DIGITAL
IN connector for the Main Zone. If an ANALOG IN
connector is also selected, it will be ignored. The unit will
mute when an invalid digital audio input type is received.
Valid digital audio input types include PCM, Dolby Digital,
and dts(-ES). The DIGITAL setting will automatically be
selected when the ANALOG IN parameter on the INPUT
SETUP menu is set to NONE (see page 3-6).
• The ANALOG setting forces the unit to utilize the selected
ANALOG IN connector for the Main Zone. If a DIGITAL IN
connector is also selected, it will be ignored. The ANALOG
setting will automatically be selected when the DIGITAL IN
parameter on the INPUT SETUP menu is set to NONE (see
page 3-5).
• The AUTO setting allows the unit to switch between the
selected DIGITAL IN and ANALOG IN connectors. The
DIGITAL IN connector is utilized when a valid digital audio
input type is present. When invalid digital audio input
types are received, the unit automatically switches to the
ANALOG IN connector. INPUT SELECT will automatically
be set to AUTO when a connect or selected for both the
DIGITAL IN and ANALOG IN parameters. This setting is
recommended for input sources that utilize both digital
and analog audio input types, such as a laser disc player.
Note:
Some sources supply valid digital audio input types
that remain active even when no audio is present in
the signal. Because the unit recognizes these as valid
digital audio input types, it will not switch to the
ANALOG IN connector. For these sources, it is
recommended to configure two different inputs - one
for digital audio input types, and a second for analog
audio input types.
ANALOG BYPASS (ON, OFF)
ANALOG BYPASS allows analog input types to bypass analog-to-
digital conversion and internal processing. When set to ON, the
unit passes the analog input signal to the corresponding analog
outputs.
For stereo analog sources, the input is sent to the FRONT L/R
outputs. For a 5.1-channel analog source, the (L) input is sent to
the FRONT L output. The (R) input is sent to the FRONT R output.
The (C) input is sent to the CENTER output. The (SUB) input is sent
to the SUBWOOFER L/R and LFE outputs. The (LS) input is sent to
the SIDE and REAR L outputs. The (RS) input is sent to the SIDE and
REAR R outputs.
Note:
It is not possible to record from an analog input
source on the S/PDIF outputs when the Main Zone is
utilizing the 5.1-channel analog input.
