Description
Entering a new dimension
The name says it all – the new HELIX DSP ULTRA is anything but another signal processor with just more channels. Rather, it is the next technological milestone that impressively demonstrates Audiotec Fischer's expertise in the field of DSP technology.
Features
- TwinDSP Power – two extremely powerful “fixed point” Audio DSPs with 64 Bit resolution and 2.4 billion MAC operations per second
- State-of-the-art 32 Bit AD and DA signal converters from AKM
- Virtual Channel Processing (VCP) allows even more flexible configuration for highly complex sound systems
- ACO – Advanced 32 Bit CoProcessor platform for numerous new system and DSP features like:
- ISA (Input Signal Analyzer) and InputEQ for easy analysis and compensation of input signals
- SFX (DSP Sound Effects) – Augmented Bass Processing, StageXpander, RealCenter & Co.
- 10 internal memory locations for sound setups
- HELIX Extension Card slot (HEC) for additional input / output modules like Bluetooth® Audio Streaming, High Resolution Audio Streaming via USB etc.
- Smart 8-channel highlevel input with ADEP.3 circuit
- Start-Stop capability down to 6V supply voltage
- “Ground lift” switch to avoid ground loops
- Control input for connecting remote controls and accessories
- Time alignment with up to 20 ms delay time per channel, additionally reverse time alignment for in-phase summation of the inputs
- Freely definable signal routing with separate matrices for line, SPDIF and HEC/AUX
- Inputs: 8 x RCA/Cinch, 8 x Highlevel, 1 x optical SPDIF and 1 x coaxial SPDIF
- Outputs: 12 x RCA/Cinch with max. 8 Volts output voltage
