Connections - Ecler AMBIT108 Bedienungsanleitung

•
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
100W RMS and 93dB SPL at 1W 1m is difficult to equal in enclosures with the same features and
price.

4. CONNECTIONS

The AMBIT108 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 AMBIT108 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 7,5W or 15W position. If sound intensity should be high, place the
switch at 30 or 60W.
The fifth switch position corresponds to low impedance operation with a maximum power
capacity of 100W. 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
4Ω 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 AMBIT108 are shipped from factory with the switch in 100V/60W 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
8Ω/100W position, it will be severely damaged.
Always respect polarity. All connections are on spring-loaded terminals.
