Downmix affects the following:
ON:
1) Toslink output will downmix 5.1 (DVD etc) channels down to 2 channels.
2) Analog Center channel is active on all sources and will output a proper mix or dedicated center channel on
DTS or Dolby sources.
3) All other Analog Channels are active on all audio sources and are derived for the Left/Right channels or from
the dedicated 5.1 channels when applicable.
OFF:
1) Toslink output will NOT downmix 5.1 (DVD etc) channels down to 2 channels, only LF/RF channels are
streamed.
2) Analog Center channel is active ONLY when a 5.1 (e.g. DVD) source is playing. The Center channel WILL NOT
PLAY normal, 2-channel stereo sources.
3) All other Analog Channels are active on all sources and are derived from the Left/Right channels or from
the dedicated 5.1 channels when applicable.
Regardless of the downmix setting, the analog center channel output will always be active during a phone call
or when a 5.1 source, like a DVD, is being played. If a center channel speaker is NOT installed in the aftermarket
installation, phone calls will come from the left and right front speaker only, instead of the left, right and center.
However, if a center channel speaker is not installed, you MUST USE the Downmix ON setting to be able to hear
vocals on 5.1 encoded sources.
