4. CONNECTIONS

The NEST106 can operate in high or low impedance. To
this end, there is a five-position switch on the front panel behind the
protective grille. This switch allows you to select the operating
mode. The first four switches allow the system to operate in high-
impedance mode and the fifth, in low-impedance mode. (*)
The four positions with a 100V/70V power line allow you
to set the maximum power that will be used by each unit. That
means that you will use the 5 or 7.5W/2.5 or 3.75W positions for areas where you would like a lower
level of sound and 15 and 30W/7.5 and 15W in areas where you would like the sound to be louder.
Note: If you use the speaker in 70V installations, the power for the 100V position will be
half the amount shown on the switch. When used in 50V installations, it will be a fourth of the
amount.
The fifth position is for low-impedance (8 Ω) mode and a maximum power of 60 W. If you
use this configuration, you should keep in mind the limits of the amplifier when several speakers are
hooked up to it, especially if the impedance of the overall installation is lower than 4 Ω. Also, it is
important that the cable used to connect the output jacks on the amplifier to the speakers is good
quality and as short a possible; this is especially important in the case of longer distances when the
impedance of the speakers is low.
(*) N.B.: The system of distributing the speakers on a 100V/70V line has historical origins in the need
to mix speakers with different impedances and/or power capacities on the same line or amplification
channel without having to worry about the total impedance of the resulting system. Also, this solution
allows you to use longer lengths of cable with a sensibly lower section than is normally used in low-
impedance installations with minimum power loss.
¡ATTENTION!:
The NEST106 is delivered with the switch in the 100V/70V position. If you accidentally hook it
up to a low-impedance system, no damage will be done to the speaker, but it will perform far under its
real capabilities. If you accidentally connect the speaker to a 100V/70V network in the 8 Ω position, this
will cause serious damage to the speaker.
