- Descrizione
- Specifiche
Il microfono a condensatore Beta 87A permette di utilizzare sul palcoscenico una qualità tipica di uno studio di registrazione. Risposta in frequenza lineare permette una ripresa delle voci precisa, dettagliata e calda.
Caratteristiche Tecniche:
- Modello di ripresa polare supercardioide a tutte le frequenze
- Shock mount pneumatico
- Risposta in frequenza: 50 – 18.000 Hz.
Specifiche Tecniche
