Unique features of the HELIX DSP ULTRA
TwinDSP Power
The DSP ULTRA contains two of the most powerful
64 Bit audio signal processors from Analog Devices
with the outstanding overall calculating power of 2.4
billion MAC operations per second.
The TwinDSP Power concept makes the twelve
separately processed channels and the numerous
new sound features in combination with the extend
-
ed sampling rate of 96 kHz (resulting in an audio
bandwidth of more than 40 kHz) possible.
ACO – Advanced 32 Bit CoProcessor
The HELIX DSP ULTRA incorporates an extraordi
-
nary powerful 32 Bit CoProcessor of the latest gen-
eration for all monitoring and communication tasks,
both internally and externally. In opposite to the
8 Bit predecessor generation this MCU achieves
way higher speeds with respect to setup switching
and data communication with our DSP PC-Tool
software. A further significant advantage is the in
-
tegrated, native boot loader of the CoProcessor. It
allows software upgrades of all components of the
DSP in order to adjust the microcontroller-controlled
ADEP.3 circuit for example at future modifications /
changes in the diagnostic system of factory radios
or if the device will be extended with additional inter
-
faces. In addition, thanks to the new flash memory,
the ACO offers 10 memory locations for sound set
-
ups instead of the common two.
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-
cific features (e.g. fader function) quite often appear
if a signal processor will be hooked up – but not with
the DSP ULTRA.
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 HELIX DSP UL-
TRA assures a constant internal supply voltage
even if the battery’s voltage drops to 6 Volts during
engine crank.
Power Save Mode
The Power Save Mode is incorporated in the basic
setup. It allows to significantly reduce the power
consumption of the amplifiers that are connected to
the HELIX DSP ULTRA 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
HELIX DSP ULTRA will reactivate the remote out
-
put within a second if a music signal is applied. It is
possible to either modify the turn-off time of 60 sec.
or completely deactivate the “Power Save Mode”
via the DSP PC-Tool software.
Automatic Digital Signal Detection
Switching from analog input to one of the digital in-
puts is done automatically as soon as a signal is
detected on the
Optical
or
Coax Input
. This feature
can be deactivated in the DSP PC-Tool software.
Alternatively you can use an optional remote con
-
trol for manual switching between analog and digital
inputs.
