Ready to Power on
After making all connections correctly we are
ready to turn on the amplifier.
You just made, the amplifier performs some
set in the reset to ensure a safe operation, this
is true both in power-on switch-off.
As sometimes happens the major problems of
high power amplifiers take over at power on
or
power down.
Our amplifiers HA series are designed not to
lie
in this unfortunate situation.
Pressed the power switch on the front panel,
the two LEDs
ILP
TM
(see fig. A) will flash for
about 3 seconds and then stay on steady.
These LEDs indicate the operating status of
the protections that serve different functions
listed below:
ILP
TM
(intelligent lock power):
At Power on:
1 - connect the speakers out after about
3 seconds (delay antibump). The LEDs
become fixed after about 3sec.
2- resets the parameters of current and
voltage of the output stages to ensure
maximum efficency
3- immediately disconnects the load in case of
failure of the transistors
4 - disconnect the load in the event of a short
circuit on the output stages
5 - disconnect the load in the event of a short
circuit on the power cables
6 - disconnect the load in the event of
prolonged clipping without damaging the
speakers.
At the power off
1 - immediately disconnects the outputs from
the load
If the LEDs flash always :
In remote eventually that something can
impair circuit
ILP
TM
quickly intervene
immediately disconnecting the load and
blocking the amplifier. The LED or two LEDs
(the 2 channels have 2 independent circuits
ILP) will flash warning that something went
wrong during the operation.
note : the circuit ILP
TM
also intervenes when
the DC output offset should increase coming
from the parameters set in the factory.
