It is possible to connect up to 2 inputs in the input and control section at the back of the speaker. Following are
only few examples of conguration used (1 input and 2 inputs).
CH1 (1): it is possible to connect a source through a cable with balanced or unbalanced connector (TRS, XLR).
Select the input type using the Input Sensitivity Switch. In particular, in case of microphone input, select "MIC".
CH2 (2): it is possible to connect a source through a cable with balanced or unbalanced connector (TRS, XLR).
Select the input type using the Input Sensitivity Switch. In particular, in case of input with high impedance, such as
the one of a guitar or a bass guitar, select "Instr". Instruments or devices with line impedance (such as a keyboard
or a stereo player) require instead a "LINE" setting.
Adjust the level of each connected channel.
Once inputs are connected, select the correct DSP preset (1).
In case of problems related to ground loops, it is possible to solve the problem by setting the relevant selector (3)
to the correct position, as shown below.
