output on that channel when present. There is one exception to this rule: rear center (RC)
content is switched from channel 5 to 7 whenever rear left (RL) content is simultaneously
present. To simplify this, RC content is thus treated as if it were two different types of
content: RC5 and RC7. When RL content is not present, RC content is output on channel
5 as RC5 content. When RL content is present, RC content is output on channel 7 as RC7
content.
Setting DAXA will automatically set
value (see table below). However, this method should not be used to gate channels.
Instead, DAXG should be used after all of the available channels have been selected.

Note: If DAXA is set to a value not found in the table above, then other parameters will not
be automatically set and an error will be generated if the format is loaded while this
condition exists.
