The versatility of these boxes together with a large program of mechanical accessories
make it possible to install systems by grouping together from two to as many boxes as are necessary
to deal with virtually every need related to the reproduction of ambient music and announcement
broadcasting.

Reliability and Quality. Above all, AMBIT cabinets have a surprisingly good quality in terms
of sound considering their dimensions. This is possible thanks to their special shape, which enables
a higher volume to be achieved than what could be imagined. A power capacity of 50W RMS and
93dB SPL at 1W 1m is difficult to equal in enclosures with the same features and price.
4. CONNECTIONS
The AMBIT106 admits operation as high or low
impedance. A 5-position switch is positioned at the back
of the speaker and allows the selection of the operating
mode. The first 4 switch position are to be used in
conjunction with a 100V line. Using a 100V speaker
distribution system has various advantages regarding
installation flexibility. First, different types of loudspeakers
(different power handling or impedance) can be used
simultaneously as required in different zones. On the other hand, the 100V line system minimizes
power loss due to cable resistance, as usually long cable runs are required in large installations.
The AMBIT106 has 4 power handling levels for the 100V line. Depending on the intended
use, the speaker output can be attenuated more or less. In the zones where sound intensity should
be low, place the switch in the 5W or 7,5W position. If sound intensity should be high, place the
switch at 15 or 30W.
The fifth switch position corresponds to low impedance operation with a maximum power
capacity of 50W. When operating at low impedance you should always consider the limitations of the
power amp when connecting several low-impedance speakers together. Impedances lower than 4
Ω
should be avoided. At low impedance operation and with long cable runs, the cables between the
amplifier and the speakers should be as short as possible and have good quality.
ATTENTION
The AMBIT106 are shipped from factory with the switch in 100V/30W position. If it is
connected to a low-impedance amplifier, the speaker will not be damaged, but will perform
way below its full potential. If the speaker is accidentally connected to a 100V line in the
8
Ω/50W position, it will be severely damaged.
Always respect polarity. All connections are on spring-loaded terminals.
