Introduction
If you are not familiar with equalisers, the best thing to do before
first turn-on is to put all controls in their central position. When the
unit is not powered or the power supply fails, the fail-safe relay of
the equaliser links input and output. By putting the controls in their
central position, you make sure that the overall gain of your system
is not changed when the fail-safe relay activates. This is a good
starting point for the exploration of the equaliser’s functions.
Once all mains and input and output connections are made
correctly, switch the unit on by pressing the “power” switch. After
app 0,2 seconds the fail-safe relay will activate and thereby link the
unit in the signal path.
The graphics on the equaliser’s front panel illustrate the different
functions of the unit and make it ergonomically pleasant to work
General operating instructions
The level control is preceding the filter section of the equaliser and
levels the input signals of the filter section. The input stage of the
equaliser is located before the level control. The level control has
thus no effect on the levels in the input stage. In case the overload
led illuminates and decreasing the level with this control has no
effect, it probably means that the input stage is in overload. The
only solution to this problem is lowering the signal level at the input
of the unit by lowering the output of the driving equipment or by
adding an external loss pad to the input wiring.
Of course the power switch is for turning the unit on and off, but if
the system is set up well (LEVEL at 0dB...), it can be used as a
bypass for the complete equaliser, making use of the fail-safe
