HELIX COMBO

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 add-ons like Bluetooth® HD 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
