Small in size, huge in sound!
High tech in compact dimensions – despite its size, the HELIX DSP MINI is crammed with state-of-the-art technology. A 64 Bit Audio DSP of the latest generation in combination with a sampling rate of 96 kHz and a High Resolution audio bandwidth up to more than 40 kHz provides phenomenal sound quality. In addition, the DSP MINI offers unique DSP sound features like the ”Augmented Bass Processing”, the “StageXpander” or the “RealCenter“ function which open new possibilities to tweak your audio system.
But not only in terms of sound quality the DSP MINI heralds a new era in signal processor technology. An extraordinary powerful 32 Bit CoProcessor (ACO) for all monitoring tasks provides a decisive speed increase particularly in data communication with our DSP PC-Tool software, but also when switching between different sound setups. Furthermore, it supplies 10 internal memory locations for sound setups instead of the usual two.
As if that weren’t enough – the highlevel input with ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation), the Auto Remote switch, an optical input as well as the HELIX Extension Card slot (HEC slot) for system add-ons like Bluetooth® Audio Streaming or High Resolution Audio Streaming via USB are, of course, part of the basic equipment.
The DSP MINI presents itself in the HELIX-typical, clean look – far too beautiful to hide it “somewhere” in the vehicle due to its small dimensions. Naturally, the HELIX DSP MINI can be configured as easy as usual thanks to the professional and particularly user-friendly DSP PC-Tool Software V4. Who said that size matters?
