Auto-standby function
The AUTO STANDBY
function (idle or low consumption mode) means you can install the
eCA120DN / eCA120HZDN in inaccessible places and leave the device connected to the
mains power supply permanently because when no signal is detected, it automatically
goes into standby mode, saving energy.
To enable the AUTO STANDBY mode, the switch labelled "
AUTO STBY
" on the rear
panel has to be in the ON position. When it is enabled and after 2 minutes or more
without any audio signal at the audio input of
the device (or a very weak signal, lower
than the activation threshold), the
eCA120DN / eCA120HZDN will automatically switch
into standby mode, lighting up the red
ON/STBY LED
located on the front panel of the
device. When a valid audio signal is detected in any of the inputs, the amplifier leaves
standby mode and starts operating normally again and the ON/STBY LED goes green.
When enabling the
AUTO STANDBY
mode with the front panel switch
(
ON
position),
one of the 2 following assumptions may occur:
a)
There is NO audio signal in the inputs. Result: the amplifier immediately goes
into AUTO STANDBY mode.
b)
There is an audio signal in the inputs. Result: the amplifier stays active.
LED indicators
•
SP
: The signal presence or
SP
LED indicator shows that there is a signal in the
amplifier input. This lights up when the input level reaches the established
detection threshold.
•
CLIP
: The saturation
(or cut off)
CLIP
LED indicator comes on when the signal
delivered to the speakers is close to the amplifier's clipping or saturation level.
Input signals should be set to ensure the CLIP indicators never stay on, but that they
do so at most to the beat of the lowest sound frequencies. Otherwise the powered
signal will be distorted with low quality and low intelligibility.
Note
: If the input signal is too high, the CLIP indicator lighting up very frequently
over a short time interval (a few seconds), the amplifier may go into protection
mode, being muted to return to normal operation in a short time.
•
ON/STBY
: The green light comes on when the equipment is in normal operating
mode and it goes red
when it is in standby or low consumption mode (STANDBY).
