Proceed as follow :
turn the amp off and wait about 3 minutes to
make sure that the circuit
ILP
TM
resets every
parameter.
turn on the amplifier and observe the return
to normal operation with LED ILP returning
fixed.
if the problem persists (LED always blinking)
contact a service center EAMLAB.
Note :
it may happen sometimes, after the
intervention of the circuit
ILP
TM
, which is
switched on again, the LED or LEDs come back
fixed but the amplifier does not emit any
sound.
This means that the circuit
ILP
TM
is working
again and the relay circuit that releases the
load does not detect the DC component in the
output because the circuit
ILP
TM
the block in
advance if it detects abnormalities in the
output stages.
Even in this case, contact the service center.
Instruction :
In any case, do not ever groped to solve the
problem alone, but immediatamnete contact
theservicecenter.
Any
unauthorized intervention by
EAMLAB immediately void the warranty.
THL
TM
thermal overload
The thermal protection system THL
TM
is
activated only in the case in which the
operating temperature of the final stages
exceeds the threshold of 90 °.
The intervention
THL will be signaled by the
fixed LEDs on the front panel (see fig.) these
LEDs will light when the heatsink temperature
reaches 70 ° and the circuit tries to keep it
stable working on current values and
polarization of the power stages.
If the temperature still rise THL
TM
circuit turns
off the relay to speaker at 90 °
If the system THL activates :
1. You can power off the amplifier and
Letting it cool
.
You can reset the amplifier on and leaving him
waiting for the circuit automatically resets the
optimal values.
Notes:
All amplifier control and protection
circuits are explained in the guide
