Unique Features of the UP 7BMW
Class HD technology
The UP 7BMW combines the advantages of a
Class H technology with the principle of a class D
amplifier. The result is an unsurpassed efficiency
which easily outperforms any conventional Class D
amplifier.
By varying the internal supply voltage depending on
the amplifier's amplitude of the input signals, idle
losses are significantly reduced and overall efficien-
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
BMW car radios are equipped with additional mon-
itoring functions so that failure messages and loss
of specific features (e.g. fader function) quite often
appear if a common amplifier will be hooked up -
but not with the UP 7BMW.
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 7BMW assures a constant internal supply volt-
age even if the battery's voltage drops to 6 Volts
during engine crank. If the supply voltage drops be-
low 10.5 Volts for more than five seconds the am-
plifier 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 significantly reduce the pow-
er consumption of the UP 7BMW and potentially
connected amplifiers once there's no input signal
present 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 amplifiers will be turned off. The
MATCH UP 7BMW 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.
