on.

Two parallel 6,mm stereo headphone jacks
for regular headphones. You can connect two
headphones of the same type at the same time.
Please avoid using two different headphones.
This may result in very different levels
3 • Volume knob
Here you can adjust the desired output level.
Turn clockwise to get a higher volume and
counter clockwise to lower the volume.

4 • Line-Input (L/R)
Inputs of the Black Cube Linear Pro XLR sym-
metrical with the following configuration:
XLR-Pin- = hot = + = Signal positive Phase
XLR-Pin- = cold = – = Signal negative Phase
XLR-Pin-1 = ground = Screen
Please use symmetrical connection wherever
possible, throughout your complete installation.
If you have to use unbalanced connections en-
sure the XLR pins 1 &  are connected together.
The maximum level is then reduced the half.
5 • Power switch
This switch separates the primary coil of the
power supply transformer from the mains volt-
age. There is no stand by mode.
6 • Fuse holder
Fuse holder for the primary fuse. In case of
replacement you must use the same type (100V
– 10V AC: 60mA slow or T • 00V – 0V AC
15mA slow or T). Due to the design of the fuse
holder the spare fuse can cause some mechani-
cal noise when moving the unit. This is abso-
lutely normal and no defect!
7 • Mains connector
IEC connector for mains voltage.
