Reliability - Protection function
This amplifier has many protecting functions that give to this product a great reliability.
These protections prevent damages either to amplifier or to loudspeakers.
1. Clip / limiter
When the amplifier output appears to be clipped, to avoid damages to the speakers, a built-in
clip/limiter automatically limits too high input signals. This function can be activated by the switch
placed on the amplifier’s rear panel (PX3600+ and PX5000+ only)
2. Over-heat protection
This equipment works at a rated temperature range (see page 15). If the environment’s temperature
exceeds the rated values or the user employment is not correct, it will cause an internal temperature
increase. In this case, output power is automatically limited until the temperature will be again into its
normal range values.
3. VHF protection (PX3600+ and PX5000+ only)
If a non-musical signal, exceeding audio range, occurs in the input, the amplifier will limit output power
to protect itself and the speakers. Normal output power will be automatically recovered when the VHF
signal is cut off.
4. Short-circuit protection
When a short-circuit occurs on the amplifier’s output (protection limit is below 1 ohm), the amplifier
will limit its output power. It will be automatically recovered as soon as the short-circuit is
removed.
5. VLF protection
If a continuous long-period non-musical signal (VLF), occurs in the input, the amplifier will
automatically attenuate the input signal and limit the output power in order to protect itself
and the speakers. Normal output power will be automatically recovered when the VLF
signal is cut off.
6. DC protection
If the output signal exceeds a rated DC voltage, an output protection function disconnects the load,
to protect the speakers.
7. Automatic “Fade-in” function
When the amplifier starts up or automatically restarts up in consequence of a protection releasing,
the amplifier output level will grow gradually, either to protect the amplifier and speakesr or to allow
the ears’ adaptation.

Maintenance
1Application range
1.1 This user manual is suitable only for DAD manufactured PX Series products.
1.2 PX amplifiers are suitable for live performances, band performances, discos, night clubs, etc...
4 Maintenance and troubleshooting:
Here you are some simple tips to check wether the equipment is damaged or not.
4.1 No output
If the signal LED lights up, then the amplifier should be ok, so , check whether the output
connection is well connected or not.
4.2 Low signal output
If the signal LED lights up and clip LED too, then check whether the output is short-circuited or not.
If the signal LED lights up and the protect LED too, then the amplifier should be in the protection status.
There are two possibilities: the former is that maybe the protection from overheating is active, the
latter is that maybe the VHF protection is active (PX3600+/PX5000+only).
If you take the signal off, then you can test whether it is the VHF protection or not.
If the amplifier case temperature is very hot, it probably should be the overheat protection.
4.3 If after the above mentioned check-up, the problem is still not solved, please return the equipment
to a qualified service centre.
Users must clear the amplifiers regularly, about one time each month. The best way is to use an high pressure
air pump (about 0.8-1.0CBM) and blow air through the air entrance on the front panel or through air exit on
rear panel. Please note that you must never turn the amplifier upside down.
5 Ordinary maintenance
3 Replacing a fuse
3.1 If the equipment appears affected by a low-grade malfunction and the fuse burns up, after having solved
the problem, replace it with another one of the same type. If the equipment appears affected by severe
damages and causes the fuse to explode, DO NOT replace it, or more severe damages might occur.
In this case, please return the equipment to your dealer for an effective repair.
2 Use circumstances
2.1 The room temperature shall be kept around 25 degree while used indoor. It can't be used in
