Setting the Channel Input Format
The channel input format determines the mono, stereo, or surround status of the
channel.
To set the channel strip input format for the selected audio track:
m Click-hold the button directly below the level meter on the Arrange channel strip, and
choose the desired input format from the menu.
The symbol on the button indicates the current status as follows:
 Mono: One circle represents a mono input format. The level meter shows a single
column.
 Stereo: Two interlocked circles represents a stereo input format. The level meter
divides into two independent columns when a stereo input format is chosen.
 Left: Two circles, left one filled, indicates a left channel input format. When this input
format is chosen, only the left channel of a stereo audio file is played back. The level
meter shows a single column.
 Right: Two circles, right one filled, indicates a right channel input format. When this
input format is chosen, only the right channel of a stereo audio file is played back.
The level meter shows a single column.
 Surround: Five circles indicates the surround channel input format. The level meter
divides into multiple linked columns (the number matches the project surround
format) when the surround input format is chosen.
