Rolls HR261 Stereo Sonic Exciter

Description

The Rolls HR261 Stereo Sonic Exciter is a two channel frequency compensation device designed to add life and animation to your sound. The frequency range that a human ear can detect is roughly 20 Hz to 20 kHz. However, the frequency response a normal speaker can effectively reproduce is actually much less. Additionally, speakers add distortion and phase changes that make the sound different from that of the original material.

A sonic exciter restores clarity and presence to the processed signal by correcting phase changes and harmonic structure differences. In other words, it puts the components of the sound back where they belong. All of this is done by the use of all-pass filtering, frequency compensated gain adjustment, and frequency compensated domain delay. What this means is the elements of sound are fanned out like a deck of cards, making each sound more audible and distinct, reducing the need for higher volumes and radical equaliser adjustments. This is designed to make for a more realistic and pleasing sound.

Key Features:

• Sub-Woofer output.
• Both XLR and RCA inputs and outputs.
• Restores the signal’s clarity and definition which were lost in previous electronic devices.
