Smart highlevel input
The latest generation of OE car radios incorpo-
rates sophisticated possibilities of diagnosing the
connected speakers. If a common amplifier will be
hooked up failure messages and loss of specific
features (e.g. fader function) quite often appear -
but not with the M FOUR.
The new ADEP circuit (Advanced Diagnostics Error
Protection) avoids all these problems without load
-
ing the speaker outputs of the OE radio during high
volumes unnecessarily.
Start-Stop capability
The switched power supply of the HELIX M FOUR
assures operation even if the battery’s voltage
drops down to 6 Volts during engine crank.
