Key Features

Universal Sound Processor - Pioneer DEQS1000A-I

pastingThe DEQ-S1000A is Pioneer's Universal Sound Processor, designed for upgrading the sound quality of your factory vehicle stereo and speakers. Since the originally fitted stereo does not need to be replaced, installation* is simple. Due to it's compact size, it can be installed out of sight, adding to a cleaner installation.

The DEQ-S1000A incorporates Pioneer's full custom high performance 48-bit dual-core DSP for high quality premium sound reproduction. An internal clock and pattern are optimally tuned. Sound degradation from jitter noise is thoroughly eliminated.

When used along with Pioneer's Sound Tune app, you can bring high end audio to the basic factory speakers. All operations are performed easily through a compatible smartphone and a wide range of settings are accessible from live simulation settings to 31-band custom equaliser settings via the Sound Tune app.

(*Optional vehicle specific cables may be required, sold separately).
