Clip Detector
The clip detector above the level meter shows you the headroom of a track in dB.
When a signal clips, the clip detector will turn red; the value indicates the amount that
the signal needs to be reduced, in order to prevent clipping.
Up to + 6 dB will be shown. If a track clips now and then, it doesn’t really matter—as
long as the master doesn’t clip. Clicking on any clip detector will reset all clip detectors.
The Clear Overload Flag in Audio Channel Display key command has the same effect.
Pre Fader Metering
Activation of Audio > Pre-Fader Metering ensures that the level displayed by the level
meters is measured pre fader (pre pan/balance), but post Equalizer and inserts. This
guarantees the display of track levels, even if the fader is dragged all the way down.
Adjusting the Level
The fader on each Track Object sets its playback level. The recording level is not set in
Logic. It is set at the source (the device supplying the input signal). You cannot adjust
the level on the digital input. Logic’s fader is only used to control the monitoring level.
The level meter of the Audio Objects and aux sends can be shown in decibels (dB)
(default), or MIDI controller values. To change the scale, select the appropriate Object,
and alter the “Val as” parameter. A MIDI volume of 90 is equivalent to 0 dB.
The maximum boost is + 6 dB. You can reset the volume fader to 0 dB (90) by Option-
clicking on it.
When multiple Audio Objects are selected, changing their level by moving one fader is
dB-proportional. The mixing ratio of the selected channels remains constant.
An independent monitoring level is available when a Track Object is record enabled.
After arming the track, set the fader to the desired level. The original level will be
restored when the Object is disarmed. This feature is not available when using TDM
hardware, due to technical reasons.
The global Toggle (Mute) Audio Tracks key command switches the levels of all Audio
Objects between two different values. Each Object may be set to any value for both
toggle positions, allowing you to quickly switch between two basic mixes.
