The HELIX DSP.3S is the new definition of the standard for digital signal processors. Continuously refined, this 8-channel DSP presents numerous improvements in detail. Besides the obligatory optical digital input, an additional coaxial digital input now provides the best conditions for connecting high-resolution signal sources with a sampling frequency of up to 192 kHz.

Features

Extremely powerful 64 Bit “fixed point” Audio DSP with 1.2 billion MAC operations per second
High Resolution audio bandwidth up to more than 40 kHz for unrivalled sound quality
A/D and D/A signal converters from BurrBrown
Advanced CoProcessor (ACO) for extended feature set

Input Signal Analyzer (ISA) and InputEQ
DSP Sound Effects (SFX) such as the “Augmented Bass Processing” which dynamically optimizes the bass response of the subwoofer, the “StageXpander” that significantly widens the stereo perspective, the “RealCenter” function, which allows a perfectly focussed sound staging for both driver and co-driver and much more
10 internal memory locations for sound setups

Smart highlevel input with ADEP.3 circuit and Auto Turn-On function
Optical (max. 96 kHz) and coaxial (max. 192 kHz) digital input in SPDIF format
Compact, future-proof Smart Control Port (SCP)
HEC slot for system expansions for additional input / output modules like Bluetooth^® Audio Streaming, High Resolution Audio Streaming via USB etc.
Freely definable signal routing with separate matrices for line, SPDIF and HEC/AUX
Optimal signal path and power supply for further improved sound quality
“Ground lift” switch to avoid ground loops
Compact dimensions for easy integration into the vehicle
Easiest configuration via the intuitive DSP PC-Tool V4 software
