The SETUP Menu

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.
