SDR – Micro registratore a forma di Memoria SD

Descrizione

Il più piccolo registratore audio ad alta tecnologia… a forma di scheda di memoria SD. Piene funzionalità di memoria SD, dotata di microfono SiSonic MEMS by Knowles.

Nessun accessorio necessario – nessun software, nessun driver, nessun cavo.

Tutto ciò di cui avete bisogno è l’SDR e il suo manuale.

L’SRD è incredibilmente facile da utilizzare.

E’ sufficiente inserirlo nel PC per riprodurre o copiare i files.
