Nembrini Audio The Voltour 2 Channel All Valve Enhancer plugin is based on Thermionic Culture The Culture Vulture* unit. BIAS • T Triode valves and is good for just “warming up” a sound. • P1 Pentode mode to add odd harmonic which make the sound more aggressive, but retaining that valve character. • P2 Very unusual way of configuring a valve, even giving an extra octave at higher bias settings. Extended the possibilities of the original hardware: • Mix parameter used for parallel processing • Continuous Filter parameter • Phase parameter to blend the dry signal with the reversed phase wet signal • Auto wet output leveling • Link parameter allows for perfectly matched stereo imaging Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect Legal Disclaimer: The Culture Vulture is a registered trademark of Thermionic Culture Ltd.
