IMPORTANT!
•
Some keyboards teature "stereo outputs" which are
not mono- compatible. The two outputs sometimes
only difter by a phase shifting on the second channel.
This phenomenon is sometimes also referred to as
"quasi-stereophone".
•
As the rotor effects of both inputs are taken into
consideration (summed), this can lead to fluctuating
amplitudes or cancellations of the signal.
•
This situation can be remedied by connecting one
keyboard output with one of the Fx 70 inputs.
•
Always use well-screened audio cables.
•
To avoid loss of trebles, the cables should not be
longer than 10 metres. This especially applies to
those leading to the inputs.
•
Never position the unit directly under or on a power¬
ful amplifier, TV monitor or the like, as the leakage
field of the transformers pertaining to such applian¬
ces can cause hums influence into the electronics of
the Fx 70.
3.4 Position of the Groundlift switch
The groundlift switch serves to avoid hum loops. It must
be positioned appropriately, depending on the operating
mode in question.
UNGROUNDED: If the Fx 70 is operated with other
appliances which have a different earthing potential.
GROUNDED: If the Fx70 is operated together with other
units in a 19" rack.
