DB Technologies ES 503 - 1000W Portable Column Array PA System with 95 x 65-Degree Coverage in Black Finish

The dB Technologies ES503 is an exceptionally versatile and portable 1000W column array PA system, designed to deliver high-performance audio in a compact and easy-to-use setup. Ideal for solo musicians, small bands, DJs, and even live sound or playback applications, the ES503 offers a plug-and-play solution with impressive sound quality and adaptability. This all-in-one system includes two full-range satellite speakers and a powerful 12" subwoofer, making it suitable for a wide variety of environments, whether for intimate gatherings or medium-sized events.

The ES503 features a 1000W peak power Digipro G3 Class-D amplifier, delivering an impressive maximum SPL of 121 dB, ensuring loud and clear audio projection even in larger venues. The subwoofer is equipped with a 12" woofer housed in a durable bass-reflex enclosure, while each of the two tops includes four 3" neodymium drivers. The tops employ Logarithmic Curved Column Array technology for asymmetrical vertical coverage, ensuring sound distribution remains consistent for both seated and standing audiences. A specially designed phase plug further enhances horizontal coverage, providing crystal-clear voice intelligibility from every listening position.

This system stands out due to its built-in DSP, which controls the three-channel on-board digital mixer and includes factory presets as well as user-defined settings. The OLED display interface allows for easy navigation and control of the system, making adjustments straightforward during live performances. Additionally, the ES503 includes a stereo Bluetooth receiver, allowing users to stream audio wirelessly from mobile devices, adding further flexibility for DJs or event hosts.

One of the most notable features of the ES503 is its versatility in terms of setup configurations. Users can choose between Mono Mode, Stereo Mode, or Double Column Mode, depending on the needs of the event. Mono Mode allows for the two satellite speakers to be connected top-to-top and mounted on a pole above the subwoofer, while Stereo Mode separates the satellites, positioning one on a tripod and the other on a pole. Double Column Mode expands the system by linking two ES503 units, allowing for larger setups controlled from a single master unit.

The system's robust build makes it highly portable, with the subwoofer made from durable 15mm birch plywood and finished with a scratch-resistant black coating. Integrated handles on the subwoofer ensure easy transport, while the compact size of the tops ensures that the entire system remains lightweight and portable.
