Electronic Loudspeaker Imaging Simulating Amplifier
The acoustic illusion that transforms your headphones into a sound system
Listening with headphones has always meant sacrificing the three-dimensionality of sound. The sources seem in fact positioned between the ears or even 'inside the head,' making the listening experience less natural, less realistic.
With ELISA, this limit is overcome.
Thanks to an exclusive scientific approach and a patented technology, the ELISA circuitry reconstructs the ambiance, depth, and soundstage of a true Hi-Fi system in your headphones, thus offering an immersive experience never felt before.

Operating diagram of the ELISA technology
The ELISA circuitry recreates the three-dimensionality of listening from a speaker system in your headphones, by processing the stereo signals through a network of controlled delays and crossovers.
The result is a spatially coherent sound image, with instruments and voices positioned in front of the listener, in a virtual acoustic environment adjustable via the STAGE and ANGLE controls.
Beyond the listening experience, inside the technology
The principles that make the ELISA effect unique
Reprocessing of the right and left channels
ELISA does not simply 'reproduce' the sound like any amplifier would do. It reprocesses sound, by mixing part of the right signal into the left channel (and vice versa), and simulates what actually happens when listening to a sound system inside a room.
The system introduces controlled, delayed, and balanced crosstalk, based on an analysis of environmental acoustic phenomena. This allows the sound wave behavior to be recreated in a three-dimensional space, while maintaining phase coherence and tonal clarity.
Soundstage control: STAGE & ANGLE
With ELISA, you can adjust the sound width (Angle) and depth (Stage), tailoring the soundstage to your preferences.
STAGE: controls the intensity of the simulated environmental effect.
The 'Room' and 'Arena' modes adjust the degree of spatialization.
ANGLE: manages the width of the stereo image, from more focused ('Narrow') to very wide ('Wide').
Simulation of the listening environment: the 'room' effect
ELISA reconstructs in headphones the spatial perception normally experienced in a listening room, by making the sounds 'exit' the head and positioning them in front of the listener, with their depth and width.
This effect is achieved through a network of calibrated delays and attenuations that simulate a real listening environment. This creates a virtual soundstage where each instrument has its own position in space.
Restoration of natural coherence
When listening with ELISA, the instruments seem positioned in real space, and no longer flattened between the ears. The sound becomes natural, open, and immersive.
ELISA acts on interaural time delay (ITD) and interaural level difference (ILD) to produce a response that is consistent with human auditory perception, while maintaining the integrity of the musical message.
