dB Technologies ES1203 Stereo Column PA System

The dB Technologies ES1203 is a powerful three-channel amplified column PA system designed for live music, mobile DJs, events, presentations and professional entertainment.

The system combines two passive wooden array tops with an active semi-horn-loaded subwoofer containing two 12-inch drivers. Its 2400W peak Class D amplifier, 132dB maximum sound pressure level and 35Hz to 20kHz frequency range provide the output and coverage required for a wide variety of venues.

A built-in five-channel digital mixer, Bluetooth audio streaming and comprehensive DSP allow microphones, instruments and music sources to be connected directly. Mono, stereo and double-column configurations make the ES1203 suitable for everything from compact performances to expanded two-system setups.

Dual 12-Inch Active Subwoofer

The active subwoofer contains two 12-inch low-frequency drivers with 2.5-inch voice coils. Its semi-horn-loaded design delivers powerful and controlled bass reproduction for live music and recorded material.

A 2400W peak Digipro G4 Class D amplifier powers the complete system. Three amplified channels separately manage the subwoofer and two satellite outputs, allowing the ES1203 to operate as a genuine stereo column PA system.

The plywood enclosure features a full metal grille and durable scratch-resistant coating, providing a road-ready construction for regular mobile and venue use.

Two Compact Column Array Tops

Each satellite contains four 4-inch neodymium mid and high-frequency drivers. Together, the two tops provide eight 4-inch drivers for clear reproduction of vocals, instruments and music.

Logarithmic Curved Column Array technology creates asymmetrical vertical coverage, while specially designed phase plugs widen the horizontal dispersion. This helps distribute sound consistently across the audience while maintaining vocal intelligibility.

The satellites can be operated separately for stereo sound or locked together to form a taller mono column. Their compact wooden enclosures weigh only 3.3kg each, making them easy to handle and position.

Mono, Stereo and Double-Column Configurations

The ES1203 provides three system configuration modes to suit different applications.

In mono mode, the two tops connect together to form a single extended column above the subwoofer. The integrated locking system provides both physical and electrical connection between the two satellite sections.

For stereo operation, the tops are positioned separately on suitable speaker stands and connected to the subwoofer using the supplied speaker cables. This configuration is particularly useful for DJs, live performers and events where stereo music reproduction and wider placement are required.

Double-column mode allows a second ES1203 system to be connected through the balanced output. The two systems can then receive the appropriate left and right signals for greater coverage and output.

Integrated Five-Channel Digital Mixer

The built-in mixer provides three physical input channels plus a separate stereo Bluetooth channel.

Channel one features a balanced and unbalanced XLR and 6.35mm combination input for microphones or instruments. It includes impedance compensation, an adjustable anti-feedback filter and selectable microphone gain.

Channels two and three use XLR and 6.35mm combination connectors that accept microphone or line-level sources. This allows up to three microphones to be connected directly when required.

Bluetooth provides convenient stereo audio streaming from compatible phones, tablets and other devices. A balanced XLR AUX/MIX output can feed a stage monitor, additional powered speaker, recording system or second ES1203.

56-Bit DSP and OLED Control

The integrated 56-bit DSP is controlled using an OLED display and rotary encoder on top of the subwoofer. Its graphical interface guides the user through system configuration and provides access to input levels, equalisation, output routing and stored presets.

Digital steering settings allow the column coverage to be adjusted for different audience positions and room layouts. Peak, RMS and thermal limiters protect the system during demanding use.

Complete Portable PA Package

The ES1203 is supplied with a protective cover for the subwoofer, a padded bag for the two array tops, one telescopic pole, two 7m speaker cables and a power cable.

The modular design separates into manageable sections for transportation and storage. An optional magnetic transport dolly is also available for moving the subwoofer more easily.
