Description

The Crunch CRE400.4DSP is an exceptional 6-channel audio processor with built-in presets. It integrates a 4-channel analog power amplifier into an ultra-compact chassis. Thanks to its integrated Bluetooth module, it also allows wireless music streaming, a major asset in its category. In short, this mini DSP amplifier can power front and rear speaker systems, while an additional RCA output allows connecting another amplifier for a subwoofer via the DSP – all at an unbeatable price!

The Crunch DSP delivers unparalleled audio quality, made possible by the integrated analog-to-digital converters from the renowned manufacturer AKM – components usually found only in much more expensive devices. With an extremely low total harmonic distortion (THD) of just 0.03%, the amplifier ensures crystal-clear sound reproduction. Thanks to a slope of up to 48 dB per octave and integrated time alignment, precise adjustments are possible for an absolutely perfect sound experience. The 31-band parametric equalizer offers maximum flexibility to adapt the sound exactly to your preferences.

Crunch ingeniously offers three solutions for DSP programming: the classic method is via a PC using Windows software. The sound processor can also be programmed wirelessly using the DSP MASTER app for iOS or Android. The latter allows quick modification of the DSP or recalling presets on the go, without having to connect a PC each time.

The Crunch CRE400.4DSP-ISO kit offers the possibility to easily connect the amplifier to many car radios thanks to the included one-meter ISO cable.
