DB Technologies ES-503 Compact Pa System

Whether you're looking for a portable PA system for live sound purposes, or a high-quality stationary system for installation purposes, the ES-503 Compact PA system could well be the one for you. This simple-yet-powerful plug-and-play live sound reinforcement solution is perfect for solo musicians, small bands and even touring DJ's.

Two Mid-to-Hi Frequency "Tops" and a Low-Frequency "Subwoofer" in one package

This amazing sound-system contains a powerful 1000 Watt peak Power Amp comprising of 2 slave 4x3" full-range tops and 1 master 12" subwoofer. This awesome combination can output a total of 121 dB SPL, features a 3-band on-board digital mixer, and bluetooth connectivity for your mobile devices to connect to.

The setup allows for three different configuration options (with one optional extra needing a second system):

  • Mono Mode: both satellites are stacked and affixed to a D25mm pole protruding from the subwoofer
  • Stereo Mode 1: Each satellite is placed on its own tripod
  • Stereo Mode 2: 1 Satellite on a tripod, one on the afore-mentioned pole attachment
  • Double Column Mode (Optional): This mode features two complete ES503 systems arrayed in Mono Mode. System 1 is set as the Master for the second ES503 system, and feeds the audio signal via the integrated balanced output channel, with system 2 acting as the slave.

This rugged, well-made compact PA system is as versatile as you need it to be, and is available at a competitive price. If you have any queries regarding this product, please feel free to contact our online sales team directly.
