The AUDEO103 and 106 models allow for
operation at high or low impedance. To this end, there
is a five-position switch on the rear panel that allows
you to select the operating mode. The first four switch
positions allow the system to operate in high-
impedance mode and the fifth, in low-impedance
mode. (*)
The four 100 V power line switch positions allow you to set the maximum power that will be
used by each unit. Thus, in areas where a low sound level is required, the lower positions are used
(5 or 7.5 W for the AUDEO106 / 2.5 or 5 W for the AUDEO103), while in areas in which a higher
level is required, the higher positions are used (15 or 30 W for the AUDEO106 / 7.5 or 15 W for the
AUDEO103).
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 corresponds to operation in low impedance (8 Ω) and a maximum power
of 50 W for the AUDEO106 and 25 W for the AUDEO103. In the case of adopting this configuration,
the amplifier limits must be considered when connecting several speakers to its output, especially if
the impedance of the system falls below 4 Ω. In addition, it is important for the cable connecting the
amplifier and speaker outputs to be of good quality and as short as possible; this is particularly
important if large distances are to be covered and 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 considerably lower section than is normally used in low-
impedance installations with minimum power loss.
CAUTION:
The AUDEO106 and 103 are supplied in origin with the switch in the 100V/30W or 100V/15W
position, respectively. If you accidentally hook the system up to a low-impedance amplifier,
no damage will be done to the speaker, but it will perform far below its real capabilities. If you
accidentally connect the speaker to a 100 V network in the 8 Ω position, this will cause
serious damage to the speaker.
