ES503 is the ultimate portable column speaker PA system. Perfect as a portable PA system for live sound as well as playback applications, ES provide a simple yet powerful plug-and-play solution for solo musicians or small bands, and is the must-have sound system in the touring DJ equipment, thanks to a built in digital mixer and a stereo Bluetooth audio receiver. ES503 is a 1000W Power Amp Peak sound system composed by 2 slave 4x 3” full-range tops and 1 master 12” subwoofer. dBTechnologies’s components and design allow an amazing SPL/size ratio: 95x355x137 mm and 1.9 kg for the tops and 465x400x430mm 16,4 kg for the subwoofer for an overall 121 db SPL. The sub hosts a Digipro G3® amp module with auto-range PSU and a 3-channels mixer with Bluetooth connection. A powerful DSP manages all function of the on-board digital mixer, making the ES503 a real gem in terms of sound performance and versatility. 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. This allows ES503 to adapt to any situation, both with a seated or standing audience. 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” 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 power 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 handles (one per side) help easy transport.
