Thank you for choosing a dB Technologies Product!
ES802 is a portable bi-amped sound system composed by two passive tops and one 12" subwoofer. The sub hosts a
1200 W power amp module with auto-range PSU and a mixer. A powerful DSP manages both the coverage of the entire
system and all functions of the system, making the ES802 a real gem in terms of sound performance and versatility.
Unpacking:
The box contains:
N°1 ES Top A Satellite.
N°1 ES Top B Satellite.
N°1 ES 802 Sub.
N°1 Speakon Cable.
N°1 Power Cable.
N°1 Telescopic M20 Pole.
Easy Assembly:
The 3-piece system is light enough to be carried in a
single trip.
Mono column mode on stand pole
The satellite 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.

Ready in less than a minute:
The speakers in this series use a latest generation
digital amplifier. This highly efficient amplifier provides
high power with limited weight and dimension.
Thanks to the low power dissipated, the cooling of the
amplifier module does not require a fan. The digital
preamplifier with DSP (Digital Signal Processing)
controls
the
audio
components, the frequency response, the limiter, and
the phase alignment.
The correct switch on of the amplifier is guaranteed by
an initialization procedure; during this test stage the
LEDs ("LIMITER" and "ON/SIGNAL"), located on the
amplifier module, stay on together for approx. 2 sec. At
the end of the switch on procedure, on the amplifier
module, the "ON/SIGNAL" green LED flashes slowly,
when there is signal absence.
During normal operation the "ON/SIGNAL" green LED
serves as Vu-meter monitoring the audio level
reproduced. The "LIMITER" red LED lights up to indicate
that the internal limiter circuit has tripped to prevent
amplifier distortion and protects the speakers against
overloads. Thermal control is provided by the internal
DSP, by means of one sensor, controls the temperature
of the amplifier, avoiding overheating by limiting the
overall volume. In case of overheating (> 90°C) the
volume decreases proportionally to the temperature
increase, making the change unnoticeable. The correct
volume and all the functions are automatically restored
when standard operating temperatures are reached.
