ASC – Amplifi er Status Controller Unit
ASC handles all the amplifi er functions, except sound.
It has a microprocessor and through its Status Display, it permits to visualise working functions and possible anomalies
both of the amplifi er and of the whole system. It drives VUmeter for output power visualisation, it controls protection and
adjusts the temperature of various parts by controlling fans activation and speed.
LEFT PEAK – RIGHT PEAK (orange)
It detects the amplifi er distortion.
It is generally on when VUmeter is
completely on and shows maximum
power instantaneous attainment. It can
occasionally switch on; if it switches
on more often and persistently, you
need to decrease power. If it switches
on when VUmeter is not completely
on, it indicates anomalous distortion;
applied load may have some problems
or impedance may be too low.
POWER ON (green)
The amplifi er is on. HI POWER (green)
Dual Power is in Hi Power
confi guration.
If it is off, confi guration is Hi
Current.
FAN ON (green)
It indicates that cooling system
is working.
TEMP GOOD (green)
Flashing: wait for the best
listening conditions.
Always on: optimum listening
temperature.
LEFT CH (orange)
It shows left fans speed (4
speeds).
Fixed: minimum speed.
Flashing: intermittence
indicates the fans speed.
RIGHT CH (orange)
It shows right fans speed
(4 speeds).
Fixed: minimum speed.
Flashing: intermittence
indicates the fans speed.
BATT PRT (red)
Protection activates if power
supply voltage is lower than
11V or higher than 16V.
THERM PRT (red)
It indicates thermal protection
intervention at 90°C (194°F).
CHECK SPK (red)
Short circuit between an output
and the car chassis. Check
speakers and cables.
SAFETY PRT (red)
It indicates the intervention
of any protection. In order to
fi nd the cause of the problem,
check the following indicators:
LEFT CH, RIGHT CH; BATT PRT;
THERM PRT; CHECK SPK.
CHECK FAN (red)
One of the four fans of the side
heat sinks or the driver central
fan has stopped. Check fans
and air ducts.
SERVICE (red)
The amplifi er is broken; contact
a service centre.
VUmeter LEFT-RIGHT (green)
It shows there is signal on
LEFT and RIGHT outputs. It
starts to work at intermediate
power levels.
