3. IMPORTANT NOTE
Congratulations! You are the owner of a carefully designed and manufactured
equipment. We thank you for trusting in us and choosing our AMBIT Series
loudspeaker cabinets.
In order to get the optimum operation and efficiency from this unit, it is VERY
IMPORTANT - before you plug anything - to read this manual very carefully and
bear in mind all considerations specified within it. We strongly recommend that its
maintenance be carried out by our Authorized Technical services.
4. INTRODUCTION
The AMBIT range is more than just a line of acoustic cabinets for sound
reproduction. AMBIT is the outcome of a study on the present and immediate
future needs with respect to background music and announcements. Stores, large
mall centers, schools, conference halls, hotels, industries, offices, museums,
meeting rooms, hospitals, games areas... are just some of the most obvious places
in which the AMBIT line can be directly applied. However, the Ecler design group
has decided to go even further and, fully aware of the great variety of areas and
situations in which acoustic cabinets can be used, has finally managed to fulfill the
desires of the increasingly demanding installers and decorators:
A series of discreet cabinets that will go unnoticed, blending into their
surroundings. In this sense, the special shape of the AMBIT106/103, with
their rear parts in the shape of a cut-off pyramid, enables the box to be
installed flush with the wall in corner assemblies. Also, the box looks a lot
smaller from the front than it actually is, as the back part is hidden from view.
A unique product. No other similar box exists. The design is an exclusive
Ecler design that is out of the ordinary, distinctive and, what is even more
important, extremely adaptable to all kinds of situations. A two-way system
with a treble loudspeaker that is concentric with the medium bass
loudspeaker. The result is a square box that can be mounted in the most
suitable position in terms of operation and aesthetics.
Configurable. The AMBIT106 and 103 models have a switch that enables the
cabinet to be configured depending on the purpose for which it is to be used.
All the cabinets operate at high or low impedance and in this case, at different
powers. Simple, fast and versatile.
The AMBIT packaging contains everything you need to anchor the boxes in
the required position.

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.
5. 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.

ATTENTION: The AMBIT103 are shipped from factory with the switch in 100V/15W
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/25W position, it will be severely
damaged.
Always respect polarity. All connections are on spring-loaded terminals.
6. PLACEMENT AND MOUNTING
Consider following general rules:
Place the acoustic enclosures on solid and firm surfaces.
No obstacles should stand between the enclosures and the audience.
Although the speakers can be used outdoors, they should not be directly
exposed to sunlight or rain.
Always adjust the output sound pressure levels to the reproduction
requirements. Despite their small size, they can produce significantly higher
pressure levels than home speakers.
The AMBIT packaging contains everything you need to install the enclosure:
Two brackets.
Allen screws to anchor the box.
Miscellaneous screws and rawlplugs for the wall.
Safety runners.
One L-shaped Allen wrench.
Speaker cables can be hidden from view by choosing an adequate mounting
orientation. Although the inconspicuous AMBIT logo suggests mounting the unit
with the input connectors on the upside and the selector switch on the downside,
the enclosure can be mounted in any orientation because the high frequency driver
is concentric and the adhesive logo can be positioned anywhere.

The following diagram shows you how to install the AMBIT103 using the accessory
supplied, so that it can be oriented both vertically and horizontally.
NOTE: As a general safety rule, remember to put the runner in place and also that
the screw marked “1” should be placed at the upper part of the support, so that if it
becomes loose, it will not fall.
Other installation possibilities:
The AMBIT103 has 4 nuts inserted in the rear at a standard diagonal distance
of 60mm, to permit the safety sling screw to be housed and to be coupled to a
standard bracket.
Ecler offers a wide range of mechanical accessories that can be used to group
several AMBIT, thus enhancing their versatility even more. Please refer to
your Ecler distributor or visit www.ecler.com for all existing possibilities.
