Unique Features of the UP 7DSP
Class HD technology
The UP 7DSP combines the advantages of a
Class H technology with the principle of a class D
amplier. The result is an unsurpassed efciency
which easily outperforms any conventional Class D
amplier.
By varying the internal supply voltage depending on
the amplier’s amplitude of the input signals, idle
losses are signicantly reduced and overall efcien-
cy is close to maximum at any time.
Smart highlevel input ADEP.3
Modern, factory-installed car radios incorporate so-
phisticated possibilities of diagnosing the connect-
ed speakers. In particular the latest generation of
car radios are equipped with additional monitoring
functions so that failure messages and loss of spe-
cic features (e.g. fader function) quite often appear
if a common amplier will be hooked up - but not
with the UP 7DSP.
The new ADEP.3 circuit (Advanced Diagnostics
Error Protection, 3rd Generation) avoids all these
problems without loading the speaker outputs of the
OE radio during high volumes unnecessarily.
Start-Stop capability
The switched power supply of the MATCH UP 7DSP
assures a constant internal supply voltage even if
the battery’s voltage drops to 6 Volts during engine
crank. If the supply voltage drops below 10.5 Volts
for more than ve seconds the amplier goes to
“Protect mode” (Status LED lights up red) in order
to avoid any further discharge of the car’s battery.
Automatic Digital Signal Detection
Switching from analog input to the digital input is
done automatically as soon as a signal is detec-
ted on the Optical Input. This feature can be deac-
tivated in the DSP PC-Tool software. Alternatively
you can use an optional remote control for manual
switching between analog and digital inputs.
Power Save Mode
The Power Save Mode is incorporated in the ba-
sic setup. It allows to signicantly reduce the power
consumption of the UP 7DSP and potentially con-
nected ampliers once there’s no input signal pres-
ent for more than 60 seconds. Please note that in
many up-to-date cars with “CAN” or any other in-
ternal bus structures it may happen that the radio
remains “invisibly” turned on for up to 45 min. even
after locking and leaving the car! Once the “Power
Save Mode“ is active the remote output and there-
fore the connected ampliers will be turned off. The
MATCH UP 7DSP will reactivate the remote output
within a second if a music signal is applied. It is pos-
sible to either modify the turn-off time of 60 sec. or
completely deactivate the “Power Save Mode” via
the DSP PC-Tool software.
