dB Technologies ES 503 array set

Beschrijving

ES503 is a 3-amped stereo sound system composed by two passive tops and one 12” subwoofer. The sub hosts a 1000W power amp module with auto-range PSU and a 3-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 ES503 a real gem in terms of sound performance and versatility.

Acoustic Coherent Coverage

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.

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 4-poles male Speakon™ connector and relauch 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.

User-Friendly Interface

The ES503 is incredibly simple to set up and comes with an intuitive wizard that guides the user step-by-step and automatically configures the system according to the application. The advanced graphical interface allows to enter the heart of the system, allowing you to recall the configuration presets, adjust levels, EQ and create a post/post gain mix for different purposes. The OLED display, visible even in the sunlight, is mounted behind an elegant smoked screen and provides all the necessary information to the total system control. All editing operations are carried out through a single rotary encoder with switch, making them extremely easy and error-free.

On-Board 3 Channels Mixer

The ES503 is equipped with a three-channel
mixer controlled by a smart DSP. The first channel features a MIC/instrument
balanced/unbalanced combo connector with impedance compensation, notch-filter
with selectable frequency and adjustable gain with 3 positions (0, +10, +
30dB). The second and third channels are LINE inputs with balanced/unbalanced
combo connector. There is a 3-band EQ that, depending on the configuration
preset, works as an overall EQ or channels EQ. A preset storable by the user is
also available.

AUX/MIX Output

The balanced AUX/MIX XLR output can be used
as a simple mono link connection, to relaunch part of the stereo mix to another
speaker system (e.g.: right output to a second ES503), or to create a new mono
mix with independent levels for stage monitoring or recording purposes. This
output is also provided with a second notch filter with selectable frequency.

Integrated Audio Bluetooth^® Module

The ES503 is equipped with built-in Bluetooth^® stereo streaming, which allows the connection of any device (such as mobile
phones, tablets or audio players) with Bluetooth^® connection. We can consider
them as 2 more inputs (for a total of 5), even though levels are common to line
inputs.

The integrated USB B-type port allows the
user upgrade the firmware of the ES503, ensuring that the system is always
updated to the latest version (download from www.dbtechnologies.com).

12” Bass-reflex Subwoofer

The bass-reflex subwoofer houses a generous
12” 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 birch 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

ES 503 System Configurations

The ES503 bundle is
composed by subwoofer, two tops, a D25mm 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 D25mm speaker stands, two 25mm tripod stands with transport bag,
speakon-speakon cable kit, wheel trolley, a bag for the ES tops and the D25mm
pole, and a bag for the 12” subwoofer.

Three configurations are available:

• Option 1: Single column mode, 1x stand pole
• Option 2: Single stereo mode, 2x tripod or
  1x stand pole and 1x tripod
• Option 3: double column mode, 2x ES 503 in
  single column mode

Option 1: single column mode, 1x stand pole

In the first option the two satellites are
connected top-on-top and are placed on the subwoofer through the supplied D25mm
pole. The system is used in mono so all inputs are routed to both outputs in
mono. Of course the user can adjust volumes, 3-band EQ and send a second mix
with different levels to the AUX/MIX output.

Option 2: SINGLE Stereo mode, 2x tripods or
1x stand pole and 1x tripod

This second option implies the use of two
tripods and two optional Speakon-Speakon cables to connect the subwoofer to the
tops placed on tripods. The system is in stereo: The Mic/Instrument input is
assigned to both channels; CH1/LINE L (and Bluetooth^® L) is assigned to Output
L; CH2/LINE R (and Bluetooth^® R) is assigned to Output R. Of course the user can
adjust pan, volumes and EQ. He can also prepare a second mix with different
levels for the AUX / MIX output.

Option 3: DOUBLE COLUMN mode, 2x ES 503 in
single column mode
