ES 503

Description

ES503 is a 1000W Peak Power sound system composed of 2 slave 4x 3” full-range tops and 1 master 12” subwoofer. The dBTechnologies components and design enable an amazing SPL/size ratio: 95x355x137 mm and 1.9 kg for the tops and 465x400x430 mm 16.4 kg for the subwoofer for a total SPL of 121 dB. The sub houses a Digipro G3® amplifier module with auto-range PSU and a 3-channel mixer with Bluetooth connection. A powerful DSP manages all functions of the built-in digital mixer, making the ES503 a true gem in terms of sound performance and versatility. The internal design of the tops allows for asymmetrical vertical coverage (thanks to Logarithmic Curved Column Array technology) and a unique “double ringed” phase plug widens horizontal coverage and guarantees perfect speech intelligibility. This allows the ES503 to adapt to any situation, with both seated and standing audiences.

The ES503 is the most eclectic among portable systems, offering 3 different configurations suitable for hundreds of different occasions:

1 MONO MODE: The two satellites are connected top-on-top (thanks to a quick and easy slide connection system) and placed on the subwoofer via a D25mm pole.

2 STEREO MODE: each satellite is placed on a tripod

2b STEREO MODE: 1 Satellite on a pole, 1 on a tripod

3 DOUBLE COLUMN MODE: an ES503 system in mono mode becomes the master for a second ES503 that feeds the signal thanks to the integrated balanced output channel. In this way, both systems are controlled by the on-board mixer of the master and each setup is guided by the master’s OLED display.

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

The bass-reflex subwoofer houses a 12-inch woofer and the amplifier module. In addition to the input connectors and user interface controls, there are two Speakon outputs and a VDE power connector. The enclosure, sturdy and stylish, is made of birch plywood coated with a durable scratch-resistant black layer, making it truly road-ready. Two handles (one per side) ensure easy transport.
