dBTechnologies ES 503 Portable Active PA System is a portable 3-amped stereo sound system composed by two passive tops and one 12” subwoofer. 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.

Acoustic Coherent Coverage 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.

Fast Speaker Connection 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 Speakonconnector and relauch the audio through the quick connection system on top of its cabinet. The “B“ satellite is both equipped with the Speakonconnector 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.

User-Friendly Interface 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. On-Board 3 Channels Mixer The ES503 comes complete 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.

AUX/MIX Output The balanced AUX/MIX XLR output can be used as a simple mono link connection, to relaunch part of the stereo mix to another speaker system (e.g.: right output to a second ES503), or to create a new mono mix with independent levels for stage monitoring or recording purposes. This output is also provided with a second notch filter with selectable frequency.

Integrated Audio Bluetooth Module The ES503 is equipped with built-in Bluetooth stereo streaming, which allows the connection of any device (such as mobile phones, tablets or audio players) with Bluetooth connection. We can consider them as 2 more inputs (for a total of 5), even though levels are common to line inputs. The integrated USB B-type port allows the user upgrade the firmware of the ES503, ensuring that the system is always updated to the l
