Mic In 1 and 2 have these additional entries:
Pre Amp Gain
Sets the current gain/amplification. Choices are 0 dB, and +9 up to +60 dB in steps of 3 dB.
+48V
Activates phantom power for condenser microphones or special accessories (Alva Test Plug).
Phantom power should only be activated when condenser microphones that require such a
power supply are used, and only in the specific channel. Additionally always make sure the
microphone is plugged in first before the phantom power is switched on. The MADIface turns on
the phantom power smoothly (soft start). Connecting and disconnecting microphones while
phantom power is active causes a high voltage surge, which can destroy the sensitive micro-
phone input stage.
Phantom power is only applied to the XLR socket, the inner TRS contacts do not carry any volt-
age.
AutoSet Gain
Automatic overload protection by gain reduction in case of overload.
AutoSet
tries to keep a
headroom of 6 dB. Levels higher than -6 dBFS will permanently reduce the gain. To check set
the channels to a high gain and apply an input signal. The displayed gain will quickly decrease
to a gain that is appropriate. While AutoSet in the XT is not exactly the same as in the RME
Micstasy (with extreme overloads distortion will occur for the fraction of a second before the
level is set correctly), it works quite well in real-world applications and will prevent distorted
recordings reliably.
AutoSet can be activated in CHANNEL as well as on the Mic
Gain screen: a push on encoder 1 and 2 activates AutoSet. The
label AS in the display changes from light gray to black.
To avoid shifts in panorama AutoSet should work in stereo mode
(ganged), so that gain changes of one channel are also applied
to the other one. This function is activated by setting
Channel
Type
to
Stereo
. Other than all other channels Mic will still have
two entries. But TotalMix FX changes to a stereo channel, and
AutoSet is linked between both channels.
As soon as AutoSet reduces the gain the label AS, shown in the Mic Gain screen, changes its
color from black to blue.
All output channels have these additional entries:
Volume
Sets the output level from -64 dB up to +6 dB, in steps of 1 dB.
Mute is also available.
Balance
Adjustable from -1 (left) through 0 (middle) to +1 (right). Greyed
out on mono channels
FX Return
Amount of Reverb/Echo mixed to the current output.
