Helix DSP MINI MK2 | 6-channel digital signal processor

.

The smallest HELIX signal processor gets a worthy successor with the DSP MINI MK2. Like its predecessor, this compact DSP is a real technology package.

A powerful 64-bit audio DSP and BurrBrown converter, combined with a 96 kHz sampling rate and a high resolution audio bandwidth of over 40 kHz, ensure exceptional sound quality. The MK2 also presents itself at a top level in terms of measurement technology - a higher maximum output voltage of 6 volts, significantly increased signal-to-noise ratios and reduced distortion values ensure the perfect sound.

Of course, the DSP MINI MK2 is based on the ACO platform with 32-bit CoProcessor, which not only handles all control tasks with speed, but also enables proprietary sound effects such as Augmented Bass Processing or RealCenter and, last but not least, a channel-separated input EQ including input signal analyzer (ISA). .

Seamless integration and maximum control even in the tightest spaces

The space for installing sound systems in modern vehicles is becoming increasingly limited. This makes it more difficult to connect individual components and puts strain on plugs and cables. The Smart Control Port (SCP) of the DSP MINI MK2 allows the multifunctional connection of accessory products and now even takes over their complete power supply. The solid construction and the snap-in function guarantee a stable connection, prevent cable and connector damage and thus facilitate space-saving installation concepts.

Everything on board

The equipment package makes it clear that the name of the DSP MINI MK2 only refers to the dimensions. Because when it comes to functionality, compromises are absolutely taboo!

Our intelligent high-level input with ADEP.3 circuit (Advanced Diagnostics Error Protection, Generation 3), the "Auto Remote" switch and an optical digital input are just as obvious as the HELIX Extension Card Slot (HEC Slot) for system expansion with e.g. Bluetooth® HD or High Resolution Audio Streaming via USB.
