Description
ES is a portable -amped stereo sound system composed by two passive tops and one
" subwoofer. The sub hosts a W peak power amp module with auto-range PSU
and a -channels mixer with Bluetooth® connection. A powerful DSP – controlled through
an advanced user-interface with an OLED display – manages both the coverage of the
entire system and all functions of the mixer, making the ES a real gem in terms of
sound performance and versatility.
The ES Series is the result of experience gained from dBTechnologies in the acoustic
design of vertical array systems like DVA T Series and MINI. The components of the top
are aligned mechanically (Logarithmic Curved Column Array) so as to increase the
coverage of the vertical beam. Furthermore, there is a special "double-ringed phase
plug" that increases the horizontal coverage and gives a rich and crystal clear sound to
the system.
The bass-reflex subwoofer houses a generous " woofer and the amplifier module. In
addition to the input connectors and controls of the user-interface, there are two Speakon
outputs and a VDE Mains connector. The enclosure, sturdy and stylish, is made of plywood
coated with a durable scratch-resistant black coat, which makes it truly road-ready. Two
recessed handles (one per side) help easy transport. Finally the metal grid with foam, in
addition to protecting the woofer and give a very elegant and professional look, helps
the reflex effect. The lower part of the grid, placed right on the reflex ports, have in fact
holes with a larger diameter to enhance air flow.
ES System Configurations
Fast Speaker Connection
The enclosure of the two satellites embeds a slide
connection system, which assures perfect top-to-top
matching without the risk of incorrect assembly. It also
includes the electrical connection between the two tops. The
letters A and B marks these two speakers respectively,
making them easily identifiable. The "A" satellite receives
the powered signal from the subwoofer through a -poles
male Speakon™ connector and relaunch the audio through
the quick connection system on top of its cabinet. The "B"
satellite is both equipped with the Speakon™ connector and
the quick connection system, but in case of stacked use its
position must be over the "A" speaker. In other words, both
tops can be used on speaker stands or poles, but in case of
vertical array the default setup must be respected.
The ES bundle is composed by subwoofer, two tops, a Dmm pole and a
Speakon/Speakon cable to connect the sub to the first top. The speaker pole is splittable
in two segments for easy transport. The system also provides a large group of accessories,
such as Dmm speaker stands, two mm tripod stands with transport bag, speakon-
speakon cable kit, wheel trolley, a bag for the ES tops and the Dmm pole, and a bag
for the " subwoofer.
