dB Technologies ES 503 Column PA System

The dBTechnologies ES 503 is a top-tier portable column PA system, perfect for live performances, DJ sets, and playback applications. Designed as a powerful plug-and-play solution for solo musicians, small bands, and touring DJs, the ES 503 features a built-in digital mixer and stereo Bluetooth™ receiver, making it an all-in-one system for any occasion.

Compact System with Remarkable Power

The ES 503 delivers an impressive 1000W peak power and consists of two 4 x 3” full-range satellite tops and a 12” bass-reflex subwoofer. Together, they produce a powerful 121 dB SPL, offering exceptional sound quality in a compact, easy-to-transport system. The subwoofer houses a Digipro G3® amplifier module with an auto-range power supply and a 3-channel mixer with Bluetooth™ connectivity, allowing seamless control over audio sources and settings.

Precision Sound with Wide Coverage

The ES 503’s satellite tops utilise Logarithmic Curved Column Array (LCCA) technology, providing asymmetrical vertical dispersion for consistent sound coverage. A unique double-ringed phase plug further enhances horizontal coverage, ensuring clear, intelligible audio across any space. Whether for seated or standing audiences, the ES 503 delivers pristine sound quality in all environments.

Multiple Configuration Options for Maximum Flexibility

The ES503 offers 3 versatile configurations to adapt to various applications:

• Mono Mode: The two satellite tops connect in a top-on-top configuration via a slide connection system and mount securely on the subwoofer using a 25mm pole.
• Stereo Mode: Each satellite is placed on a tripod (sold separately) for true stereo sound.
• Double Column Mode: A mono-configured ES 503 system can act as the master for a second ES 503 (sold separately) via the balanced output channel. In this setup, both systems are controlled by the master’s onboard mixer and OLED display for synchronised performance.

Advanced DSP and Intuitive Control

The ES 503 is powered by a cutting-edge DSP module that precisely manages crossover, frequency response, limiter functions, and phase alignment, ensuring optimal audio performance. The onboard digital mixer allows for complete control of audio sources, while the built-in Bluetooth™ module supports stereo audio streaming from mobile devices such as smartphones, tablets, or other Bluetooth-enabled equipment.

Durable, Road-Ready Design

Built to withstand the demands of touring and live performances, the ES 503’s 12” bass-reflex subwoofer is encased in a durable birch plywood enclosure, coated with a scratch-resistant black finish. Two recessed side handles make transportation effortless, while the sturdy metal grille with foam lining protects the woofer and enhances airflow through the reflex ports for deeper bass response. The rear panel includes two Speakon outputs and a VDE power connector for easy setup and reliable performance.

All-in-One Solution for Any Event

Whether used as a standalone system or paired with another ES 503 in double column mode, this versatile and powerful PA system adapts effortlessly to a wide range of events. From intimate gigs and conferences to high-energy club performances, the dBTechnologies ES 503 guarantees exceptional sound quality, ease of use, and reliable performance every time.
