Adjusting Mixer Parameter Controls
You can adjust some parameter controls on several channel strips simultaneously.
To adjust the Volume fader on all selected channel strips
µ
Drag the Volume fader of any selected channel strip.
All level changes are relative and logarithmic. Movements are dB-proportional, with the
mix ratio of the selected channel strips remaining constant. For example, if channel strip
1 is set to 90 dB and channel strip 2 is set to 60 dB, reducing either Volume fader will
retain the relative distance between the channel strips:
• At half the original level, channel strip 1 will be at 45 dB and channel strip 2 at 30 dB.
• At a quarter of the original level, channel strip 1 will be at 22.5 dB and channel strip 2
at 15 dB; the mix ratio thus remains constant until both channel strips simultaneously
arrive at 0 dB.
• When either channel strip is returned to its original value, the 60/90 dB relationship in
this example is restored.
To adjust knobs on all selected channel strips
Do one of the following:
µ
Drag the Pan/Balance knob on any selected channel strip.
All Pan or Balance knobs change accordingly (the changes are relative).
µ
Drag the Send level knob on any selected channel strip.
All Send level knobs change accordingly (the changes are relative).
To adjust buttons on all selected channel strips
Do one of the following:
µ
Click the Mute or Solo button on any selected channel strip.
The buttons of all selected channel strips mirror the status of the clicked button.
µ
Click the Record Enable button on any selected channel strip.
