Acus Phantasma - PREAMPLIFIER WITH PIEZO PICKUP AND MICROPHONE FOR CLASSICAL AND ACOUSTIC GUITAR

(This text is machine translated) The Phantasma project stems from the need for a high quality guitar amplification system that meets the following requirements: Lightweight and as less invasive as possible without controls and battery on board to respect the integrity of the guitar, to avoid blocking vibrations. Inside the guitar there is a microphone capsule and a piezo with a thickness of 0.8mm. Nothing else, 30 grams of total weight. The Phantasma provides the circuitry in an external compact preamp box connected to the guitar via a stereo cable (included). The class A preamplifier takes into account all the constructive characteristics of the instruments and returns to the output an extremely natural sound adjustable by the HPF and LPF filters and by separate mic / piezo volumes. No feedback. The Acus engineering team conducted research on the "zone X" of the resonant frequencies to avoid amplifying them. Its operating principle is based on the combination of harmonics detected by the microphone with ...
