210 Chapter 10 Working With Instruments and Effects
Before continuing, there are three main things you need to know about audio or
instrument channel strips: the channel input format, the Pan control, and the Level
fader.
Setting the Channel Input Format
The channel input format determines the mono, stereo, or surround status of the
channel.
Software instrument and external MIDI channels do not have a format button.
The chosen input format has an impact on two things:
 The plug-ins shown on the channel strip will be available as:
 Mono to mono or mono to stereo versions on mono channel strips
 Stereo to stereo versions on stereo channel strips
 Surround or multi-mono versions on surround channel strips
 The Pan control determines the position of the channel signal in the stereo field.
 On mono channels (this includes left and right input format channels), the Pan
control determines the left/right position of the signal.
 On stereo channels, the Pan control determines the balance between the left and
right channel signals.
Note: To access the surround panner, you must first set the channel output format, via
the Output menu on the channel strip.
