plugging the power cord into the wall outlet, use the same fuse as marked on
the fuse holder at the AC power connection. The mains connection of the

is made by using the enclosed mains cord and a standard IEC receptacle.

It meets all of the international safety certification requirements.

connecting to the mixing console's main inserts, or on an entire mix "in-line" between
a mixing console's outputs and a power amplifier. The defective wiring may degrade

following section to be the real master of your own unit. Not paying attention
enough to the input signal level, to the routing of the signal and the assignment
of the signal will result in unwanted distortion, a corrupted signal or no sound
