dB Technologies ES 503 Column PA System

The ES503 is a 1000W (Peak) sound system consisting of 2 slave 4x 3 ”broadband tops and 1 master 12” subwoofer. The components and design of dBTechnologies enable an amazing SPL / size ratio: 95 x 355 x 137 mm and 1.9 kg for the top and 465 x 400 x 430 mm, 16.4 kg for the subwoofer with a total of 121 dB SPL. The sub contains a Digipro G3 amplifier module with PSU with automatic range and a 3-channel mixing console with Bluetooth connection. The powerful DSP controls all the functions of the built-in digital mix, making the ES503 a real gem in terms of sound performance and versatility. The internal design of the top allows for asymmetrical vertical coverage (thanks to Logarithmic Curved Column Field technology) and the unique double-ring phase connector expands the horizontal coverage and ensures perfect voice intelligibility. This allows the ES503 to adapt to any situation, whether with a sitting or standing audience.

The ES503 allows 3 different configurations suitable for hundreds of different occasions:

• MONO MODE: The two satellites are connected from the top to the top (thanks to a quick and easy sliding connection system) and are placed on the subwoofer via a D25 mm rod.

• STEREO MODE: Each satellite is placed on a tripod
• STEREO MODE (2): 1 satellite on a pole, 1 on a tripod

• DOUBLE COLUMN MODE: The ES503 system in mono mode becomes the main ES503 for the second time, which delivers a signal thanks to the integrated balanced output channel. In this way, both systems are controlled by the master's mixing console and any settings are made through the main OLED display.

The ES503 is equipped with a three-channel mixing console and a built-in Bluetooth stereo module that receives sound from devices such as mobile phones, tablets or any other audio device.

The bass-reflex subwoofer includes a 12 ”subwoofer and an amplifier module. In addition to the input connectors and user interface controls, there are two Speakon outputs and a VDE power connector. The solid and stylish cover is made of birch plywood covered with a durable black scratch-resistant coating, making it truly road-ready. Two handles (one on each side) facilitate transport.
