Review: A VERY WELL PRESENTED ISOLASTOR
Review: Dynavox GLI 2.1 - Nel mio caso è stato miracoloso togliendo ronzii causati da loop di massa quindi altamente consigliato però solo se il problema è questo..quindi come già detto da altri utenti controllate che il problema sia legato ad un anello di massa.. il suono dopo l'intervento del dynavox non ha subito grosse variazioni in negativo anzi sembra più aperto e dettagliato anche se leggermente meno dinamico...

## Features

- Metal casing
- Elimination of interference signals and hum loops
