1.  Power on/off switch: flip the switch to power the speaker on or off. Always 

power off the unit when not in use. 

2.  AC inlet socket: connect the included power cord here.  AC mains voltage is 

230VAC ±10%/50-60 Hz. The mains fuse is located inside the cabinet and 
must be replaced only with an identical fuse. If the fuse blows up regularly, 
have your unit serviced by a qualified service technician.

3.  RCA input: 2 identical RCA connectors for unbalanced line level signals. The 

line-in and link connector are internally connected in parallel, allowing you to 
link the signal through to one or more active speakers. 

4.  XLR input: male and female XLR connectors for balanced line level signals. The 

line-in and link connectors are internally connected in parallel, allowing you to 
link the signal through to one or more active speakers.

5.  Treble tone control: Center position = neutral. To the left = less treble, to the 

right = more treble.

6.  Bass tone control: Center position = neutral. To the left = less bass, to the right 

= more bass.

7.  Volume: turn clockwise to increase the volume. When turned counterclockwise 

to the limit, the audio signal present at the inputs is muted.

8.  Power LED: lights up green when the power cord is connected to a working AC 

outlet and the power switch is turned to the on position.

9.  Clip LED: this red LED lights up when the internal power amplifier is 

overloaded. Reduce the volume so that the clip LED does not light up during 
use. When the sound is distorted, the signal level at the inputs is too high. 
Reduce the output from your audio source (pre-amplifier) in such cases.

10. Heat sink: keep the heat sink free from dust, do not cover the heat sink and 

ensure sufficient airflow in this area.
