LAB - Dummy Head Microphone
Amadeux Dummy Head Binaural Mic Project
 Progetto Testa microfonica Amadeux #1 per Registrazione Binaurale
testi e immagini a cura di Marco Stefanelli, Ph.D.
 Avviato nel gennaio 2021 il progetto per la realizzazione di una testa microfonica professionale per registrazione binaurale a basso costo su ispirazione e modello della Neumann KU100.
 Prototipo #1 funzionante in silicone e polistirolo
 Prototipo #2 funzionante in PVC e schiuma poliuretanica
 Apertura posteriore e uscita jack 3.5 stereo
 Interfaccia jack 3.5-XLR phantom stereo
 Rack outboard per i vari test
  Silicon ear dummy
