21. SIGNAL / PEAK indicator
The Signal / Peak indicator provides optical information of a channel’s actual signal level
at all times. As already mentioned in the chapter “GAIN”, the “signal present” LED should
blink in the rhythm of the incoming signal. If this is not the case, increasing the input level
using the gain control is necessary. On the other hand, if the PEAK LED lights constantly,
the corresponding channel is likely to enter clipping and you have to reduce amplification
using the gain control. The “signal present” LED lights at levels 30dB below clipping while
the peak LED lights at a level of 8dB below the occurrence of overdrive. To prevent the
mixer’s input channels from clipping, which for instance may be caused by increasing
volumes, keeping an eye on these indicators during operation is a good idea, too. Of course,
engaging a channel’s PFL-button allows monitoring that channel’s level via the display in
the master section. Be sure to only engage the PFL-key of the channel that you are about
to adjust. The channel’s level is displayed in the master display’s left LED-chain. Here as
well, make sure that the red LED (+12dB) lights only briefly during dynamic peaks.
22. CHANNEL FADER
Stereo Fader for setting the volume of a stereo channel.
Different from the fader function of the MIC input channels, here, the audio signal is not
amplified when a channel fader is set to its maximum position. To be sure to use the mixer’s
entire dynamic capacity, set the CHANNEL FADER during playback to its maximum
position.
