Thank you for choosing a dB Technologies Product!
ES503 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.
1) Unpacking:
The box contains:
N°1 ES 503 Top A Satellite
N°1 ES 503 Top B Satellite
N°1 ES 503 Sub
N°1 Speakon Cable
N°1 Power Cable
N°1 Telescopic M20 Pole
2) Easy Assembly:
The 3-piece system is light enough to be carried in a
single trip and can be configured in 3 different modes:
Option 1: Mono column mode, 1x stand pole
The two satellites are connected top-on-top and are
placed on the subwoofer through the supplied D25mm
pole. The system is used in mono mode so all inputs are
routed to both outputs in mono.
Option 2: Stereo mode, 2x tripods or 1x stand pole
and 1x tripod
This implies the use of two tripods and two optional
Speakon-Speakon cables to connect the subwoofer to
the tops placed on tripods. The system is in stereo: The
Mic/Instrument input is assigned to both channels;
CH1/LINE L (and Bluetooth
®
L) is assigned to Output L;
CH2/LINE R (and Bluetooth
®
R) is assigned to Output R.
The user can adjust pan, volumes and EQ and can also
set up a second mix with different levels for the AUX /
MIX output.
Option 3: DOUBLE COLUMN mode, 2x ES 503 in single
column mode
Two ES 503 systems in single column mode: one system
becomes the master for the other, feeding the signal
thanks to the integrated balanced output channel.
In this way, both system are driven by the master’s on-
board mixer and any setup is guided through the
master’s OLED display.
