Unique Features of the PP 82DSP
Power Save Mode
The Power Save Mode is incorporated in the ba-
sic setup. It allows to significantly reduce the power
consumption of the PP 82DSP (or any additional
connected amplifier) once there’s no input 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 therefo-
re the PP 82DSP 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 82DSP 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
Class HD and P³S power supply technology
For the first time the PP 82DSP combines the ad
-
vantages of a Class H technology with the principle
of a class D amplifier. The result is an unsurpassed
efficiency, which easily outperforms any conventio
-
nal class D amplifier.
The new P³S power supply technology controls the
internal supply voltage for the output stages as a
function of the amplitude of the input signal. Thus
the average power dissipation of the amplifier is
dramatically reduced.
Like all other MATCH amplifiers the PP 82DSP is
perfectly prepared for cars with start-/stop feature.
Please note:
Nevertheless the PP 82DSP 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) in order
to avoid any further discharge of the car’s battery.
