Whether you're upgrading to a premium multi-channel sound system or even designing a completely new sound configuration, HELIX V PROPER DSP is an all-in-one tool for anyone with insatiable sound system goals. This multi-purpose DSP sets new standards for the improvement and implementation of highly complex sound systems.

The new 32-bit ACO platform allows you to do everything fast, but it also does a lot more. Key features include signal analysis and automatic response straightening of OEM audio sources. This compensates for the input signal distortion often introduced in OEM equipment to compensate for poor quality original speakers.

HELIX V PROPER DSP installs seamlessly into the back of any OEM audio source ADEP.3 The 4-32 volt input sensitivity of the speaker-level input allows installation on the rear of OEM amplifiers in cars where removal from the rear of the player is impossible.
