5.1
Rack installation
Install the unit on a plane surface or in your rack. For 19" (483 mm) rack installation, 1 unit is required. When
mounting the unit into the rack, please make sure that there is enough space around the device so that the
heated air can be passed on. Steady overheating will damage your device. You can fix the unit with four
screws M6 in the rack.
5.2 Connecting audio devices
All connections have to be made or changed only if the unit and all audio devices connected to it is/are
switched off!
The inputs and outputs of the
