Unique Features of the PP 52DSP
Power Save Mode
The Power Save Mode is incorporated in all car-
specific setups as well as in the basic setup of the
PC-tool software. It allows to significantly reduce
the power consumption of the PP 52DSP (or any
additional connected amplifier) once there’s no in
-
put signal for more than 60 seconds. Please note
that in many up-to-date cars with “CAN” or any
other internal bus structures it may happen that the
radio (and therefore the PP 52DSP as well) remains
“invisibly” turned on for up to 45 min. after leaving
the car!
Once the “Power Save Mode is active the output
stages of the PP 52DSP and its “Remote Output”
will be turned off, thus reducing current draw to less
than 250 mA. The amp will turn again to full operati-
on within 2 sec. if a music signal is applied.
It is possible to either modify the turn-off time of
60 sec. or completely deactivate the “Power Save
made” via the PC-tool
MCM power supply technology
This technology delivers a perfectly stabilized supp-
ly voltage for the internal amplifier stages indepen
-
dent on any fluctuation of the battery voltage, even
during cranking the car’s engine.
Like all other MATCH amplifiers the PP 52DSP is
perfectly prepared for cars with start-/stop feature.
Please note:
Nevertheless the PP 52DSP has an undervoltage
protection. If the supply voltage drops below 9.6
volts for more than 5 seconds the amplifier goes to
“Protect mode” (Status LED lights up red).
MicroSD
The microSD card reader allows to easily configure
the DSP inside the amplifier without the need of
directly connecting a personal computer. A large
number of car-specific setups is available for free
on www.audiotec-fischer.com. Simply download
your desired setup and copy it to any microSD card.
Finally insert the microSD card into the PP 52DSP
and the copy process will start automatically. After
that the amplifier is perfectly programmed to drama
-
tically upgrade the sound quality of your car factory
audio system.
