This flux will create, by induction, a current in the two audio cables. The
voltage, at the end of each of these cables, will superimpose itself
unfortunately onto the signal coming from the cartridge. By removing one of the
jumpers, the loop is broken, and the current is prevented from being
generated. From this experience we can see that it is beneficial to keep the two
signal cables as close together as possible.
In principle the connection “X” between the two chassis has no effect in this
case. However, this will create a sensitive loop which could induce hum on the
channel which is connected to ground.
C1. The tone-arm is mounted separately and
the outputs are floating
In this third case, both the jumpers are
installed and the link between the two
chassis “X” is obligatory.
For those who have a high-output MM
cartridge fitted to the tone-arm, you
can bypass the input transformers if
desired (see jumpers section). If this is
the case you lose the facilities of
floating solutions mentioned above.
