loop is made every time two components have their chassis
connected to the electric net’s earth (mid hole of wall outlets)
and an electrical continuity is present between their chassis and
their circuit’s ground: as all system’s components ground are
connected together, a closed loop is made in which a disturbing
current flows and it generates a spurious signal: the hum.
To minimize this effect it can be useful to reduce the loop area
at a minimum by connecting all components to the same power
distribution strip, avoiding the use of wall outlet which are
physically far from each other.
NEVER TRY to open the loop by altering the earth
connection of one or more components. The connection
between earth and components’ chassis is mandatory for
user’s safety and is imposed by laws! Every change to the
connection between earth and Talia’s chassis or to the
connection of any other component of your system
exposes you to great risk of electric shock, and it
increases the possibility of causing damages to the
components

Partenope is provided with four single-ended inputs (that is
unbalanced, phono input included) and a balanced input. It’s
provided both with pre single-ended and with pre balanced
outputs. Both outputs are operative, no matter the selected input:
thus, it is possible to connect the power amplifier to Partenope
via the balanced connection and to listen to any single-ended
source, and vice versa. This is made possible by the intrinsic
auto-balancing feature of Partenope.
Usually, a single-ended connection between a source and
Partenope or between Partenope and the power amplifier is
perfectly satisfactory, but it may happen that a balanced
connection is preferable. For example, when a source or a power
amplifier is provided with balanced XLR connectors only, the
balanced connection is required (this is often true with
professional or professional-derived components).
Another common instance in which a balanced connection
between Partenope and a power amplifier is preferred is when
the power amplifier is far from Partenope. This happens usually
when the sources are placed close to the listening “sweet spot”,
while the Partenope is close to the speakers to minimize length
of the power cables and to maximize the dynamic performance
of the system. A long unbalanced interconnect can pick-up noise
despite its shielding. Instead, a balanced interconnect offers
greater rejection to disturbances and is therefore recommended.
