Technology / ACIV

Introducing the latest in sound processing technology: Clarion’s AC Processor IV. For vibrant, dynamic sound that’s straight out of a movie theatre or concert hall, Clarion’s newest version of its spatial analysis technology puts you in total control. Engage Clarion’s Time Alignment Control to adjust the time delay of each speaker, or correct irregular reflection and polarisation with the Virtual Space Enhancer. Source units equipped with this technology also offer a Parametric EQ for extreme system customisation, as well as Clarion’s exclusive ADF audio enhancer.

ADF (Anti Distortion Filter) is a newly developed equalising system, which is designed to match the peaks of the frequency curve with the original one. Conventional tone control or loudness is effective for emphasising bass/ treble sound, however, due to phase discordance, it sometimes damages the original sound. Thanks to Clarion’s latest sound technology, ADF is able to reinforce bass/treble sound without causing such distortion, so that the original sound can be lively reproduced after equalisation. Three preset patterns and one user memory are provided.

Virtual Space Enhancer digitally compensates for irregular reflection, polarisation, and other acoustical problems associated with a vehicle’s interior design.

Dolby Pro Logic II is a matrix sound decoding technology developed by Dolby Laboratories that decodes any two-channel audio source, such as a CD or radio broadcast, and outputs it as virtual 5.1-channel sound. Clarion was the first to incorporate this innovation, which brings the sonic experience of a live concert right into the car. And since it’s equipped with a Centre-Width Control and a Matrix Mode that simulates the centre-channel speaker using the front L/R speakers, you can reproduce a virtual 5.1-channel surround sound effect from a standard four-speaker setup. Users also have additional modes to choose from, all of which were created to enhance the listening experience inside your vehicle.

With Clarion’s Parametric EQ users can precisely adjust the centre frequency position and level, as well as the steepness of the equalising curve. Users can also switch to professional sound control for additional system flexibility. So, for sound that’s customised to your musical tastes, give Clarion’s Parametric EQ a try.

Calibrate your sound system so you’re sitting in the “seventh row, centre” spot (optimum listening position) of your vehicle. Because music content is recorded so that imaging is in the centre of the right and left speakers, Clarion’s Time Alignment Control allows users to adjust the speaker acoustics so that the same effects can be heard in any listening position inside the car. This feature also allows you to optimise your system to account for the number of passengers inside your vehicle’s interior cabin.

Allowing maximum system performance, Clarion’s built-in crossovers separate the sound spectrum so tweeters reproduce only high-range frequencies, and subwoofers reproduce only low-range frequencies. Users can also tailor the system to support future upgrades by individually adjusting the crossover frequency, filter, slope and phase.
