dB Technologies ES503 Column PA Stereo System

Description

The ES503 from dB Technologies 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 configured 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 first channel features a MIC/instrument balanced/unbalanced combo connector with an adjustable anti-feedback filter, 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 filter 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 configures the system according to the application. The advanced graphical interface allows to, recall configuration 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-reflex subwoofer houses a 12” woofer and the amplifier 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.
