Bespoke Signal Mapping
Meridian Bespoke Signal Mapping utilises digital signal processing to apply tailored crossover filters that are designed specifically for each configuration of drive units within a loudspeaker.
E3 Bass
Meridian E3 Bass uses specifically designed filters to expand, extend and enhance the low-frequency response of the loudspeaker.
Image Elevation
Image Elevation psychoacoustically raises the sound image to the centre of a screen – where the listener would expect to hear it from.
FFA
FFA (Full Frequency Alignment) is a combination of digital filters and delays to correct the group-delay of a loudspeakers. It ensures that all frequencies reach the listener’s ear at the same time.
Pro-Active Bass
Meridian Pro-Active Bass protects the bass drivers from over-excursion, ensuring maximum bass output without damaging the drive units.
Pro-Active Thermal
Meridian Pro-Active Thermal monitors the audio being sent to the mid-range drivers and tweeters and limits the overall volume of the loudspeaker if there is a risk of the drive units getting too hot.
True Time
True Time is Meridian's proprietary Apodising Filter that avoids pre-ringing and cleans up the effects of early filters, converting pre-echo to post-echo.
True Link
Meridian True Link is an encryption method for transferring high-definition digital audio over SPDIF connections. It allows secure movement of digital audio whilst ensuring that the SPDIF clock signal can be transmitted with minimum degradation.
HPA
Meridian's HPA (High Powered Array) processing technology minimises destructive interference between the multiple loudspeakers when used in an array configuration.
Architectural Performance Range
Our Architectural loudspeakers incorporate resolution enhancing technologies for the ultimate listening experience in a large range of installation applications. With virtually no visual impact to the decor, these powerful, full-range in-wall solutions require only a 100mm mounting depth and produce wide sound dispersion over the listening area.
