These four processes: EQ, dynamics, balance and gain are controlled from the internal menu
associated with the SELECT button on the main screen of the Control and Monitoring section.
2.1.1.6. ON-AIR LED
Under the lights of active processes is located the ON AIR warning light. This light is ON when
the audio signal present at the input of the channel is sent to any of the outputs previously
described. For further details refer to section 3.4.3.1.3.2 ROUTING MENU of this manual.
For this, two conditions must be met simultaneously:
• Channel fader is located in any position except at minimum of travel of the
fader.
• Channel ON key has to be activated.
ON AIR Indicator
2.1.1.7. Fader
100mm conductive plastic fader. The fader travel is printed with 11 bands, the maximum output
level +24 dB corresponding to the last, and the third band from above to +4 dB or nominal
operating level. Both of these marks are differentiated in size from the rest.
100mm fader calibration
The response mode of the fader is logarithmic, producing great attenuation of the level at the
bottom of the fader travel and less adjustment the top.
The bottom position of the fader travel, triggers gain - ∞ dB or absence of signal, which is also
reflected in the channel ON AIR indicator – off. There is around 20db of reserve gain from
nominal +4dB operation level and +24 maximum operation level.
