72 ARTEMIS Digital Broadcast Production Console Processing Audio
Frequency
Each band has a full frequency range
from 20Hz to 20kHz. This is controlled by
the 2nd Control cell row from the bottom.
Response
Pressing the RESP button for any band
in the top row of Control cells allows
the rotary control to scroll through the
available response types. The button
will be lit during this process. Once
the response has been chosen it can
be selected by pressing the button a
second time. When the RESP button is
not pressed, the rotary doubles as the Q
control. Fig 2 shows the Response Types
and parameters.
EQ curve display
The TFT touchscreen above the Control
cells shows a graphical representation
of the current EQ curve for the assigned
channel with it’s band markers, numerical
values and response type.
Note that a thumbnail view of the EQ
curve is also made available in the
PROCESSING-EQ button cell selector.
