Description
ES503 is a 1000W 3-amped sound system
composed by 2 slave 4x 3” full-range tops and 1
master 12” subwoofer. The sub hosts a Digipro
G3® amp module with auto-range PSU and a
3-channels mixer with Bluetooth connection.
The internal design of the tops allows an
asymmetrical vertical coverage (thanks to the
Logarithmic Curved Column Array technology)
and a unique “double ringed” phase plug widens
the horizontal coverage and guarantees a
perfect voice intelligibility.
The 3 elements composing the system (2 tops and
1 sub) can be congured in 3 different modes:
1 MONO MODE
2 STEREO MODE
3 DOUBLE COLUMN MODE
The enclosure of the two satellites embeds a
slide connection system, which assures perfect
top-to-top matching without the risk of incorrect
assembly and includes the electrical connection
between the two tops. The “A” satellite receives
the powered signal from the subwoofer through a
4-poles male Speakon™ connector (included in the
box) and relaunch the audio to the “B” top.
The ES503 is equipped with a three-channel
mixer controlled by a DSP.
The rst channel features a MIC/instrument
balanced/unbalanced combo connector with
an adjustable anti-feedback lter, impedance
compensation and microphone gain with 3
positions (0, +10, + 20dB). The second and
third channels are LINE inputs with balanced/
unbalanced combo connector. The system is
provided with several preset equalizations, and
each user can create and save its own custom
equalization.
The balanced AUX/MIX output can be used as a
direct link, or, alternatively, as an AUX output. In
this case, you can actually feed a stage monitor or
another speaker for which a custom separate mix
is needed. In addition to that, a dedicated notch
lter is available in order to avoid any feedback.
The system is equipped with a built-in extended
range Bluetooth® stereo module, which receives
audio from devices such as mobile phones,
tablets or any other audio device with a
Bluetooth® connection.
ES503 comes with an intuitive wizard that guides
the user step-by-step and automatically congures
the system according to the application. The
advanced graphical interface allows to, recall
conguration presets, adjust levels, EQ and create
a pre/post gain mix for different purposes. A
rotary encoder with button allows to control any
operation easily and quickly.
The bass-reex subwoofer houses a 12” woofer
and the amplier module. In addition to the
input connectors and controls of the userinterface, there are two Speakon outputs and a
VDE power connector. The enclosure, is made
of birch plywood coated with a durable scratchresistant black coat.
