The device must only be connected with an electric installation carried out in compliance with the IEC-
standards. The electric installation must be equipped with a Residual Current Device (RCD) with a maximum
fault current of 30 mA.
STARTING UP
Make sure to power-up before your power amplifier is turned in order to avoid loud transients which could
damage your speakers or annoy your audience.
System test
After connecting all cables, you should carry out a system test. Press all four Mute-buttons in order to mute
all outputs.
Activate the HF-outputs first. In case of wrong cabling, HF-signals will come out of bass-speakers that cannot
be harmed this way. Vice versa, the LF-signals would destroy your HF-speakers.
