Gain Here the microphone input gain can be set. The gain is indicated by the blue
bar graph and in the Gain field; it is adjusted with the rotary encoder below
the field.
The Gain value displayed is depending on the systems reference line level
for 0dBFS. As a default, the reference level (Maximum Level) is set to +15
dBu, resulting in a displayed mic Gain range of –11 to +75 dB.
For installations where analog line levels other then +15 dBu are used, it is
necessary to specifiy this Maximum Level level in the Configuration Tool.
See chapter 6.5.14. The displayed microphone input gain value will then
automatically be adapted to match this specified Maximum Level.
Here are a few examples - as reference levels typically are depending on the
geographical region of the broadcast station :
Maximun Level (Ref) = 0dBFS Mic Gain range typically used by Region
+ 15 dBu
-11 .. +75 dB Belgium, Germany, Switzerland
+ 18 dBu
-8 .. + 78 dB
EBU R68, most european coun-
tries, BBC
+ 22 dBu
-4 .. + 82 dB Japan, France
+ 24 dBu
-2 .. + 84 dB USA, Australia
Please note that there is no relation between the gain setting and the config-
ured headroom, since the headroom setting is only used for the level meters’
0 dB indication at nominal level.
Note: The mic clip limiter on/off button that was found on the CHAN - Input pages
of microphone inputs with SW versions below 3.0 was moved; this function
can now be accessed via the configuration tool. Refer to chapter 6.5.1.
Shared Microphone Inputs Since the microphone input parameters +48 V (phantom power on/off), HPF,
Mic Insert and Gain are realized on the physical microphone input card
rather than in the DSP channel, they are unique for all sharing logical inputs.
In case of split desk, A/B desk, or I/O sharing operation, these parameters
are accessible only by one system at a time. Access to the microphone input
parameters must be requested in the CHAN - Input page of the user GUI; the
corresponding Mic Control Access button is visible only if the microphone
input is shared. (For information on A/B and split desk configurations refer
to chapter 7; on I/O sharing refer to chapter 6.5.22).
In case of split desk mode, the secondary desk usually has no screen for dis-
playing the user GUI; so the access to mic parameters has to be controlled
from the primary desk.
A user requesting access to the mic input parameters can do this only if nobody
else has done so already on another system within the same network, the Mic
Control Access button is gray and indicates FREE, as shown below.
