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.
With the audio controls in certain positions, the overall impedance of the loudspeaker may
decrease at certain frequencies. It is therefore always recommended to use high quality cables
(low resistance and low reactance per linear metre) and power amplifiers with high output
current.
