Operation with a Computer
The USB port allows transmission of digital audio signals in both directions between the mixer and the
computer. As soon as the mixer is connected to a computer, it will be recognized as a standard USB audio
device and the required drivers are installed.
1
You can control the mixer using the standard audio interface controls in the Mac and Windows
operating system. For data transmission from the mixer to the computer the USB interface of the mixer
must be selected as the recording device. For data transmission from the computer to the mixer the
USB interface of the mixer must be selected as the playback device.
2
Open your playback/recording software to make the required adjustments for audio playback via the
mixer or for audio recording from the mixer.
3
With the selector switch TAPE/USB TO MIX, the audio signal coming from the computer can be
switched to the master channels. With the selector switch TAPE/USB TO CTRL RM/PHONES it can
monitored via headphones and a monitor system.
4
For recordings with the computer, the USB port sends the digital master signal.
Note: If the mixer is connected to both a computer and to a unit grounded via the mains cable (e.g.
amplifier), noise interference may occur due to ground loops. To eliminate this interference, a ground
isolator (e. g. OMNITRONIC LH-082) may be used to connect the mixer to the unit.
Adjusting the Effect Send Way
Connect the effect unit to the output AUX SEND and to the input STEREO AUX RETURN of an input.
1
To make sure that the subsequent effect adjustments are audible, first set the control MASTER AUX
SEND to mid-position.
2
Use the controls AUX SEND to add the signals of the input channels to the effect way. The signal will
be picked up after the level control LEVEL, i. e. the effect part of a channel is always proportional to the
channel level adjusted.
3
Use the control AUX SEND MASTER to adjust the total level for the output signal of the effect way
which is sent to the input of the effect unit. The signal received from the effect unit is added to the
master signal via the jacks STEREO AUX RETURN.
Monitoring via Headphones and Monitor System
1
When the button TAPE/USB TO CTRL RM/PHONES is not pressed, the master signal adjusted with the
master level control is indicated by the LED level indicators and can be monitored via the outputs CTRL
