User Manual

User's Guide MADIface XT © RME

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.
