Read the security advices on page 6!
2
Read the installation instructions of the included external
power supply on page 8.
3
Make sure that the Power switch on the rear is set to O
(O = out position / ON = in position).
4
Connect the included power supply to the DC input and
an appropriate mains socket outlet.
5
Connect your speakers to the Speaker Outputs.
You can connect two pairs of active stereo speakers – A and B. The A
Speaker Output has a dedicated Sub Output for an active subwoofer.
6
Connect your headphone to the headphone output.
7
Connect your analog sources to the Line Inputs.
8
Connect the Line Out to your analog audio device.
The Line Out plays back the signal from Line Input 1, Line Input 2 or
Line Input 1 and 2 summed – depending on the Line input switch.
The level is unity gain, thus independent of the volume control.
91
Set the dip switch to your needs.
Dip switch 1 on/down = attenuate the speaker outputs by 10 dB.
Dip switch 2 = n.c. (not connected).
10
Turn down speaker and headphone volume.
11
Switch the on Control One by pressing the Power button.
12
Choose speaker output A or B.
13
Select a monitoring mode: stereo, mono or L/R swapped.
14
Set the volumes and the crossfeed to taste.
15
Playback your music from the Line Inputs.
16
For playback switch between the Line Input 1, 2 or the
sum of Line Input 1 and 2.
17
Have fun!
