OPERATION AND USAGE
7.1. Start up
Start up the eCA120HZ by connecting the equipment to an external power source to
which the
DC 24V
connector of the eCA120HZ has already been connected. The LED
indicator
ON/STBY
immediately lights up on the front panel. We recommend you turn
on all the devices in the following order: sound sources, mixer, equalisers, active filters
and processors and, finally power amplifiers. Powering off should be done by following
the exact reverse sequence. Following this order, the introduced noise due to turning on
or switching off the devices will not affect those further on in the chain and will be
inaudible.
Once turned on, the front volume control (VOLUME) and the controller connected to the
REMOTE port (if any) may be used to set the output volume of the signal amplified by
the unit.
7.2. AUTO STANDBY Function
The
AUTO STANDBY
function (idle or low consumption mode) means you can install
the eCA120HZ 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 jumper labeled "AUTO STBY" on the front
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 eCA120HZ will automatically switch into standby mode, lighting
up the amber
ON/STBY
LED located on the front panel of the device. When a valid audio
signal is detected in any of the inputs, the eCA120HZ 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 jumper (
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
