A Versatile Member of the "ES" Family by dBTechnologies
Designed to deliver professional sound reinforcement in a compact format, the ES 1203 combines two passive wooden satellites and an active subwoofer. Its latest generation Digipro G4 amplification and column architecture ensure controlled coverage and excellent intelligibility, while remaining easy to deploy on stage or in installations.
Who Is It For and What Are Its Uses?
The ES 1203 is aimed at mobile DJs, acoustic bands, rental companies, conferences, and venues hosting spoken word events. In stereo on stands or in mono with coupled columns, it adapts to the room and event, from intimate cocktails to live performances requiring extended reach.
Key Technologies and Features
Each satellite houses 4 x 4" drivers aligned in a Logarithmic Curved Column Array, offering asymmetrical vertical coverage and widened horizontal dispersion thanks to dedicated phase plugs. The 56-bit DSP provides guided presets, equalization, near/far modes, and the choice of mono, stereo, or double column via an intuitive OLED screen.
The integrated mixer handles up to three microphones simultaneously via XLR/Jack combos, one MIC/Instrument channel with anti-feedback filter and 3-position gain, plus a stereo Bluetooth channel. The balanced XLR output can serve as a link, auxiliary, or left/right send to a second ES 1203 in double column mode. The package includes a subwoofer bag, tops bag, 35 mm telescopic pole, two 7 m Speakon cables, and power cable for a ready-to-use solution.
