5.2.8 Connection to the mains
AC CONNECTION
Connect the supplied power unit here. Use the mixer only with the supplied OMINTRONIC power unit.
Always disconnect the mains connector when you wish to change connections or move the device to a
different place.
POWER SWITCH
Press this button to start operation.
6. INSTALLATION
Install the device on a solid, plane, anti-slip, vibration-free, oscillation-free and fire-resistant surface.
Make sure that the power switch is set to OFF. Before you connect the devices, all units have to be switched
off.
A good cable run improves the sound quality remarkably. Input cables should be short and direct, since high
frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that a longer cable may
lead to humming and noise trouble. If long cable runs are unavoidable, you should use balanced cables.
In order to obtain highest sound quality, only use high-quality cables for connecting the devices. Make sure
that the cables are properly fixed.
At the mono input channels, the microphone signals are connected via the XLR-sockets, the line-signals via
the jack sockets.
Please note that for the mono channels, you can only use either the microphone or the line input. Never
use both simultaneously.
You can also run a stereo channel in mono by connecting only the left input socket.
