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 ONE.
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 ONE
assures operation even if the battery’s voltage
drops down to 6 Volts during engine crank.
Unique Features of the HELIX M ONE
In series
Two subwoofers with one voice coil (single voice coil)
or one subwoofer with dual voice coil are connected in
series.
Note:
The connection of two voice coils in series will re
-
sult in doubling the impedance!
Maximum output power of this configuration:
Two subwoofers with 1 x 2 Ohms
correspond to a total
impedance of 4 Ohms: 240 / 480 Watts
One subwoofer with 2 x 2 Ohms
also corresponds to a
total impedance of 4 Ohms: 240 / 480 Watts
Two subwoofers with 1 x 1 Ohm
correspond to a total
impedance of 2 Ohms: 410 / 820 Watts
One subwoofer with 2 x 1 Ohm
also corresponds to a
total impedance of 2 Ohms: 410 / 820 Watts
Note:
The connection of subwoofers with 4 Ohms in
series results in a low output power of the amplifier!
One subwoofer with
a dual voice coil
Two subwoofers with
a single voice coil
