CONNECTIONS

Partenope offers numerous options for connection to different
sources, to loudspeakers and to a power amplifier.
The absolute phase of the signal (that is the relationship between
Absolute phase
the phase of the incoming signal from the source and that of the
signal sent to the power amplifier) can either be maintained or
inverted on each channel, depending on the source polarity and
on the phase of the recording.
The selected input maintains the absolute phase when the color
of the related indicator is blue; it inverts the phase when the
color of the related indicator is red. The phase setting of the
selected input can be changed by pressing button No5 on the
remote control (see "Remote Control").
The phase setting for each input is stored on a non-volatile
memory, thus the setting is restored at turn-on and it's not
necessary to use this command every time power is cycled.
Many loudspeakers give better performance when driven in bi-

wiring. This technique requires the use of a pair of cables to
drive the low frequency section of the loudspeaker and another
pair of cables to drive its mid-high section. To implement this
technique it is necessary for the speakers to be provided with
two pairs of binding posts.
Because of its small dimensions Partenope is provided with a
single pair of output binding posts, it is necessary to connect
two cables to each post. It is advisable to choose cables with
terminations that don't apply excessive strain to the posts of the
amplifier. A good choice could be using bananas for one cable
pair and spades for the other, such as to use both connection
modes offered by the posts.
If you wish to use an amplifier other than Partenope (passive

multiamping, p. 36) this must be connected to the pre out output
of Partenope (see p. 23, n.8/9). The external amplifier will be
able to drive for instance low frequencies while Partenope
amplifying section will be able to drive the high frequencies
(passive bi-amping). In order to avoid unbalances it is important
that the external amplifier has the same current gain as
Partenope.
If you have an electronic crossover (adjustable or customized to

preamplifier and the power amplifier of Partenope after having
