SETUP - Gain
Generally about the Gain Display
Whenever you touch one of the Input gain encoders on the front,
the Gain display will appear, and disappear after a few seconds.
If you don’t want the display to go back automatically, you can
set the Auto Pages parameter on the Utility display to OFF.
Gain
At the left of the display, there are two “knobs” showing the
analog input gain. The inner circle indicates the position of the
Input encoders on the front panel, and the indications on the
outer circle along with the dB value below, shows you the
amplification of the input. If the input gain is set to +18dB, you
must have an input signal at -18dBu to get 0dB output.
After a Total Recall or an Auto Gain Set, the two indicators may
not be linked, in which case, it’s the outer indication along with
the dB value that is actual. Turn the input encoders on the front
until the indicators link, so that manual adjustment of the gain
becomes possible again.
Auto Gain Set
The Auto Gain Set option enables you to automatically set the
optimal mic or line input levels.
16
Note: The 60 dB PAD is not used at Auto Gain Set, this may
cause the message Too Much Level to show up even though it’s
possible to set optimal gain with the 60 dB PAD. If possible
switch to Line inputs and run the Auto Gain Set again.
Select
Selects what channel(s) you are working with: Ch.1, Ch.2, Ch.1
and Ch.2 or Stereo. The difference between Ch. 1 + Ch. 2 and
Stereo is that in the former you’ll get two independent
measurements at the same time, and in the latter, you will get the
lowest gain on both inputs.
Headroom
Here you select what headroom the Auto Gain Set should give
the input signal or how far should maximum peak be from 0dB.
Auto Gain ENTER
Press ENTER and the measuring will begin. Whenever you want
you can press Enter again. The measuring will stop and the
optimal input gain will be set automatically.
NOTE: If maximum gain isn’t enough to reach the headroom
level, the message: “Insufficient level” will show up.
The Gain Display
On this page you can set and adjust the gain of the analog inputs, and use the Auto Gain Setting option, which helps
you get the best results when you are doing recordings.
To view the Gain page press the SETUP button, if you are not already there, and use the < > Menu keys to select GAIN.
Basic operation is accomplished by using the Parameter wheel to change cursor position and the value wheel to change values.
