made to individual levels prior to completing a switch by pressing the TAKE button.

To perform a special stereo switch:

2. Press MENU.
The MENU button will light in red and the Preset window will display the message “1 AUDIO.” The level windows
show the audio mode for each audio channel. In Figure 6−108, both audio channels are set to “Normal.”
