Ultra HD Class D amplier technology with
96 kHz sampling rate
The HELIX P SIX DSP MK2 is the rst Class D am-
plier with integrated DSP on the market that runs
at 96 kHz sampling rate. Therefore the audio band-
width is no longer limited to 22 kHz, but allows an
extended frequency response to more than 40 kHz.
The higher sampling rate has only been possible
by implementing the latest DSP and amplier chip
sets.
The result: a Class D-amplier with an unprece-
dented sound quality.
Ready for 24 V
It is possible to operate the P SIX DSP MK2 with a
supply voltage of 12 Volts or 24 Volts (e.g. as usual
in trucks) without the need to make any changes
to the unit.
In both operating modes the amplier will have
equal performance characteristics. This guarantees
maximum exibility for numerous applications.
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 P SIX DSP MK2 and connected
ampliers 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 internal
bus structures it may happen that the radio remains
“invisibly” turned on for up to 45 min. even after
leaving the car! Once the “Power Save Mode“ is
active the remote output (Rem Out) and the inter-
nal amplier stages will be turned off. The HELIX
P SIX DSP MK2 will reactivate the remote output
and the internal amplier stages within a second if a
music signal is applied. It is possible to either mod-
ify the turn-off time of 60 sec. or completely deacti-
vate the “Power Save Mode” via the DSP PC-Tool
software.
Start-Stop capability
The switched power supply of the HELIX
P SIX DSP MK2 assures a constant internal supply
voltage even if the battery’s voltage drops to 6 Volts
during engine crank.
Automatic Digital Signal Detection
Switching from analog input to the digital input is
done automatically as soon as a signal is detect-
ed 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.
Smart highlevel input
The latest generation of OE car radios incorpo-
rates sophisticated possibilities of diagnosing the
connected speakers. If a common amplier will be
hooked up failure messages and loss of specic
features (e.g. fader function) quite often appears -
but not with the P SIX DSP MK2.
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.
