Ecler AMPACK SERIES - Manual (Page 8)

NOTE: it is possible to connect a maximum of 16 inputs to one control potentiometer. It is necessary that
the ground terminals of all amplifiers are connected.
The connection cables can be up to 500m long if a section of 0,5mm

is used.
Consult the available accessories at your ECLER dealer or at www.ecler.com.
4.5. AUTO POWER OFF function
The AUTO POWER OFF function makes the installation of the AMPACK series more flexible
in places with difficult access, because it allows to leave the unit connected to the 220-240V 50/60Hz
supply while this will activate or deactivate itself automatically depending if there is an input signal
present or not.
In case that the level of the signal present on any of the inputs is lower than -22dBV for more
than 2 minutes, the AMPACK will switch automatically into STANDBY mode. This will be
correspondingly indicated by the ON/STANDBY led located on the unit’s upper panel, which switches
from green (ON) to red (STANDBY).
When in STANDBY mode, the power consumption of the AMPACK25 and the AMPACK80 is
lower than 10VA.
When the signal level becomes higher than -22dBV the device will automatically switch to ON
mode.
4.6. Indicators
The SP signal presence indicators (3, 5) light up when the input signal reaches
approximately -40dBV.
The CLIP indicators (2, 6) light up when the output signal for the speakers is -1,5dB below
the actual clipping threshold. This clipping system watches for eventual supply voltage variations,
thus giving always an accurate clipping indication, regardless of mains voltage deviations. It is
normal that when operating at high output power, the CLIP indicators light up in synchronisation with
the low frequencies, which carry the most energy. Nevertheless, you should avoid that the CLIP
indicators are lit continuously.
5. CLEANING
The AMPACK should not be cleaned with dissolvent or abrasive substances because
silk-printing could be damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid
soap; dry it with a clean cloth. Be careful that water never gets into the amplifier through the holes of
the front panel.
