LINE OUTPUT AND ZONE 2 OUTPUT
Line output is a 2-channel version of the selected input with fixed output level. This can be
used with a headphone amp which has its own volume control.
Zone 2 has its own volume control and can be used two ways:
- For independent source selection, connect the source using analog input, or optical/
coaxial input as long as the source is 2-channel PCM. This connection can be used in
conjunction with HDMI connection for the main zone.
- For similar operation as Line Output but with volume control, set Follow Main to Always
in the setup menu (setup is explained later).
OPTICAL AND COAXIAL DIGITAL AUDIO
If HDMI audio from a Dolby Digital, DTS, or 2-channel PCM source is problematic or takes
too long to switch, use of coax/optical audio connection is recommended (HDMI video can
still be used). Older cable and satellite AVM/MRXs often benefit from this.
The optical output provides a passthrough of coax/optical input.
