25.7.4 Aux Devices
The RME OctaMic XTC is a highly flexible hi-quality 8-channel microphone, line and instrument
preamp with integrated AD-conversion to ADAT, AES/EBU and MADI, plus 4 channels of DA-
conversion for monitoring. It can be used as universal front-end for the Fireface 400 and other
interfaces.
To simplify operation the most important
parameters of the XTC (gain, 48V, phase,
mute, AutoSet) can be controlled directly
from the TotalMix FX input channels. This
special remote control uses MIDI of any
format (DIN, USB, MIDI over MADI).
TotalMix FX version 0.99 or higher will
show the panel Aux Devices which has all
the settings to activate remote functionality.
Device Settings
¾ Digital Channels. Select where the
OctaMic XTC sends its 8 analog
channels to. With the Fireface 400 this
will be the ADAT channels 1-8.
¾ Device. At this time only the OctaMic
XTC is supported and can be chosen.
MIDI Settings
¾ MIDI In. Set the currently used MIDI
connection to OctaMic XTC.
¾ MIDI Out. Set the currently used MIDI
connection to OctaMic XTC.
¾ Device ID. Default 0. This setting
relates to the current choice in Digital
Channels.
The screenshot to the right shows what happens as
soon as the above settings have been confirmed
with OK. The ADAT channels show new elements
for phantom power, Inst/PAD, Gain and AutoSet.
Control operates bidirectional, so changing the gain
at the unit will be mirrored in the TotalMix channels.
Changing the gain in TotalMix FX will set the gain in
the unit, which is also shown on the unit’s display.
For the remote to work the XTC’s currently used
MIDI I/Os have to be set to Control. More details
are found in the manual of the OctaMic XTC.
