The versatility of these cabinets 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, AMBIT103 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 25W RMS and 87dB SPL at
1W 1m is difficult to equal in enclosures with the same features and price.

CONNECTIONS
The AMBIT103 admits operation as high or low impedance. A 5-position switch is
located at the back of the speaker and allows the selection of the operating mode.
The first 4 switch positions 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 AMBIT103 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 2,5W or 5W position.
If sound intensity should be high, place the switch at 7,5 or 15W.
The fifth switch position corresponds to low impedance operation with a
maximum power capacity of 25W RMS. 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
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.
