4-channel Class A/B analog amplifier with 6-channel Full HD audio DSP

With the sophisticated CRE400.4DSP, Crunch offers an exceptional 6-channel sound processor with pre-installed presets that integrates a 4-channel analog power amplifier into an extremely compact housing. Thanks to the integrated Bluetooth module, the device also enables wireless music streaming – a real highlight in this category. In short: the mini DSP amp offers the possibility of driving front and rear systems, while an additional RCA output allows the connection of another amplifier for a subwoofer via the DSP – all at an unbeatable price!

The Crunch DSP impresses with its unparalleled audio quality, made possible by the integrated analog-to-digital converters from the renowned luxury manufacturer AKM – components often only found in much more expensive devices. With an extremely low THD value of only 0.03%, the amplifier guarantees crystal-clear sound reproduction. Thanks to a slope of up to 48 dB per octave and integrated time correction, precise adjustments are possible for an absolutely perfect sound experience. The 31-band parametric equalizer offers maximum flexibility to shape the sound exactly to your own preferences.

Ingenious - Crunch offers three solutions for DSP programming: The classic method is carried out as usual via a PC using Windows software. Alternatively, the sound processor can also be programmed wirelessly using the DSP MASTER APP software for iOS or Android. This means you can quickly make changes to the DSP or call up presets on the go, without having to connect a PC every time.

Pre-installed presets - suitable for all tastes
The DSP amplifier already has 9 presets pre-installed. They have been designed to fit three different vehicle sizes (S, M, and L) and three individual listening preferences (Beats, Flat, and Pop). Simply choose the preset that best suits your needs. The pre-installed presets can be selected via the DSP Master app as well as the DSP Master PC software.
