Audiotec Fischer introduces HELIX P SIX DSP 6-channel amplifier with integrated digital 8-channel signal processor
The 6-channel amplifier HELIX P SIX DSP not only delivers loads of clean power and a top-notch digital signal processor, it also comes with a completely new output stage concept that combines the benefits of class D amplifiers with the sound quality of class AB technology. Audiotec Fischer’s unique “Class Ultra D” concept eliminates the negative influence of the indispensable output filters with a revolutionary concept that incorporates an analog feedback path back to the digital domain. The result: Incredible damping factor (up to 1,000) even at 20 kHz, no load dependency of the frequency response and lowest possible THD for unparalleled sound quality.
Almost needless to mention the numerous input options including SPDIF optical input, a HEC (HELIX Extension Card) slot for e.g. Bluetooth® audio streaming and even more additional functions. The P SIX DSP incorporates the same state of the art “fixed point” Audio DSP with 64 Bit resolution and outstanding processing power as the HELIX DSP PRO. Two additional RCA outputs allow extending the system with external amplifiers up to eight processed channels. Six speaker outputs with up to 215 Watts RMS into 2 Ohms, six RCA and six highlevel inputs with up to 20V RMS input sensitivity round up the P SIX DSP. Despite this impressive bundle of engineering know-how the P SIX DSP shows up with a typical, clean design that has remained very compact for easiest integration.
