6. PAN
The setting of the PAN control defines the input signal’s position within the stereo image. When set to its center position, the audio signal is fed with equal levels to the left and right master busses. The PAN section’s design ensures that the overall relative level of an audio signal is maintained, no matter to what position within the stereo image the PAN control is set.
7. FX1/2
Using the FX1/2 control lets you route the corresponding input signal to the integrated digital effects units FX1 or FX2 at variable levels. In this way assigning special effects to musical instruments or vocals is fairly simple. When establishing an
8. MUTE
Engaging the MUTE button mutes the audio signal of the corresponding input channel.
9. PFL
Engaging this button assigns a channel’s audio signal to the PFL bus. For monitoring the PFL bus signal via headphones slide the PHONES MIX fader in the direction “PFL”. Simultaneously assigning more than one channel to the PFL bus is possible, while the individual channel’s volume fader setting is not recognized (PRE FADER LISTEN). Once a PFL button is pressed, the master display automatically enters PFL/PGM mode (yellow LED below the display lights). The right
10. 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 “setting instructions”, 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 blinks frequently or 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
