Standard Connection (Single Wiring); Multichannel Audio Systems; Audio Controls - Lumina Sonus Faber Manuel Du Propriétaire

The loudspeaker connection terminals allow you to connect cables terminated with stripped cable, forks or
banana plugs.
Loudspeaker systems with bi- or tri-wiring connection are equipped with jumpers that allow you to implement
various connection schemes. Depending on which scheme you intend to adopt, these jumpers may have to be
removed.
Proper tightening and periodic verification of the terminals will help to obtain and maintain optimal performance.

3.4.1 STANDARD CONNECTION (SINGLE WIRING)

It consists in running the loudspeakers (usually a pair) with a single stereo amplifier, or with a pair of monophonic
amplifiers, using only one bipolar power cable for each channel. Complete the connection as shown in the
relative illustration.
3.4.2 BI-WIRING CONNECTION (ONLY FOR LOUDSPEAKERS EQUIPPED WITH SEPARATE INPUTS FOR
LOW AND MEDIUM-HIGH FREQUENCIES).
This scheme allows the bipolar power cables, to be connected to the Low sections and the Medium-high
sections of the loudspeakers, to be differentiated. It consists in running the loudspeakers (usually a pair) with a
single stereo amplifier, or with a pair of monophonic amplifiers, using separate bipolar power cables for each
input section of the loudspeaker. Remove the jumpers and complete the connection as shown in the relative
illustration.
3.4.3 BI-AMPING CONNECTION (ONLY FOR LOUDSPEAKERS EQUIPPED WITH SEPARATE INPUTS FOR
LOW AND MEDIUM-HIGH FREQUENCIES).
This scheme is an evolution of the Bi-wiring connection and also allows the amplifiers to be connected to the Low
sections and the Medium-high sections of the loudspeakers to be differentiated. Loudspeakers (usually a pair)
are run with two distinct stereo amplifiers, or with two pairs of monophonic amplifiers, using separate bipolar
power cables for each input section of the loudspeaker. Remove the jumpers and complete the connection as
shown in the relative illustration.

3.4.4 TRI-WIRING CONNECTION (ONLY FOR LOUDSPEAKERS EQUIPPED WITH SEPARATE INPUTS FOR
INFRA-LOW AND MEDIUM-HIGH FREQUENCIES).
This connection scheme is an extension of the Bi-wiring scheme for loudspeakers with three separable input
sections. It consists in running the loudspeakers (usually a pair) with a single stereo amplifier, or with a pair of
monophonic amplifiers, using separate bipolar power cables for each input section of the loudspeaker. Remove
the jumpers and complete the connection as shown in the relative illustration. By keeping the jumpers between
two pairs of input terminals (normally medium-low and medium-high), it is however possible to implement a
bi-wiring scheme).
3.4.5 TRI-AMPING CONNECTION (ONLY FOR LOUDSPEAKERS EQUIPPED WITH SEPARATE INPUTS FOR
INFRA-LOW, MEDIUM-LOW AND MEDIUM-HIGH FREQUENCIES).
This connection scheme is an extension of the Bi-amping scheme for loudspeakers with three separable input
sections. Loudspeakers (usually a pair) are run with three distinct stereo amplifiers, or with three pairs of
monophonic amplifiers, using separate bipolar power cables for each input section of the loudspeaker. Remove
the jumpers and complete the connection as shown in the relative illustration. By keeping the jumpers between
two pairs of input terminals (normally medium-low and medium-high), it is however possible to implement a
bi-amping scheme).
3.4.6 MULTI-CHANNEL AUDIO SYSTEMS
The above also applies similarly in the case of multi-channel systems. Obviously, the connection scheme
becomes quite complex as the number of amplifiers increases with the number of channels.

3.4.7 AUDIO CONTROLS

Top range loudspeakers give the user the possibility to adjust the acoustic output at low and/or high frequencies.
The extent of the recommended adjustment depends on the taste of the listener and on the specific peculiarities
of the environment, i.e. the absorption of the room and the diffusion of the low frequency sound components.
