Yamaha O2R Manual Do Utilizador

Auxiliary Channels

Input channels 1 through 16 are mono inputs. The stereo input channels 17 
through 24 are paired together and handle two signals: left and right. 
Before feeding a stereo input signal to the auxiliary level controls, the left 
and right signals are summed to form a mono L+R mix.

The auxiliary sends can be turned on or off for quick A-B comparisons by 
using the [ON] button in the AUX group of the SELECTED CHANNEL 
controls. When the send for a channel is turned off, the send level icon for 
that channel continues to show the current level setting for the channel, but 
the text underneath the icon switches to “OFF” giving you a quick visual 
indicator of the channel send status:

The LED inset in the [ON] button is illuminated when the send for a 
channel is turned on.

The auxiliary sends can be configured as pre-fader or post-fader. This 
setting can be changed by selecting a channel with a [SEL] button or the 
CURSOR buttons and pressing the [ENTER] button for that channel.

If you select a channel with a [SEL] button or the CURSOR buttons and 
double-click the [ENTER] button, all channels will be set to the same 
pre-fader or post-fader status as the selected channel.
