The dB Technologies ES503 Portable PA System is a portable all-in-one compact PA system that delivers a whopping 1000W of crystal clear audio despite its lack of size. It is ideal for the travelling musician, conference speaker or the space conscious DJ and offers a variety of different set up options ensuring users are never limited or boxed in by their purchase and product choice. Other related accessories (purchased separately) include speaker stands, cases and a transport trolley showcasing the fact that no detail has been spared by dB Technologies when it comes to the practicality of this product.

Whether it is performed or streamed music, the high quality of sound is projected from two passive top speakers and one 12" subwoofer housed within a road ready solid birch shell.

The sub hosts a 1000W power amp module with auto-range PSU and a 3-channels mixer with Bluetooth® connection. A powerful DSP - controlled through an advanced user-interface with an OLED display - manages both the coverage of the entire system and all functions of the mixer, making the ES503 a real gem in terms of sound performance and versatility.

The ES Series is the result of experience gained from dBTechnologies in the acoustic design of vertical array systems like DVA T Series and MINI. The components of the top are aligned mechanically (Logarithmic Curved Column Array) so as to increase the coverage of the vertical beam. Furthermore, there is a special "double-ringed phase plug" that increases the horizontal coverage and gives a rich and crystal clear sound to the system.

The enclosure of the two satellites embeds a slide connection system, which assures perfect top-to-top matching without the risk of incorrect assembly. It also includes the electrical connection between the two tops. The letters A and B marks these two speakers respectively, making them easily identifiable. The "A" satellite receives the powered signal from the subwoofer through a 4-poles male Speakon™ connector and relauch the audio through the quick connection system on top of its cabinet. The "B" satellite is both equipped with the Speakon™ connector and the quick connection system, but in case of stacked use its position must be over the "A" speaker. In other words, both tops can be used on speaker stands or poles, but in case of vertical array the default setup must be respected.

The ES503 is incredibly simple to set up and comes with an intuitive wizard that guides the user step-by-step and automatically configures the system according to the application. The advanced graphical interface allows to enter the heart of the system, allowing you to recall the configuration presets, adjust levels, EQ and create a post/post gain mix for different purposes. The OLED display, visible even in the sunlight, is mounted behind an elegant smoked screen and provides all the necessary information to the total system control. All editing operations are carried out through a single rotary encoder with switch, making them extremely easy and error-free.

The ES503 is equipped with a three-channel mixer controlled by a smart DSP. The first channel features a MIC/instrument balanced/unbalanced combo connector with impedance compensation, notch-filter with selectable frequency and adjustable gain with 3 positions (0, +10, + 30dB). The second and third channels are LINE inputs with balanced/unbalanced combo connector. There is a 3-band EQ that, depending on the configuration preset, works as an overall EQ or channels EQ. A preset storable by the user is also available.
