Used as a donor preamp
Unsoldered the electret and its supporting components, I already have them fitted in my application. I just needed a very high gain amplifier with good solid output for speech. Works a treat, used as 40dB amplification.

Satisfait de cet achat.
Manque une notice technique en ligne pour expliquer toutes les fonctions.par ex, l' AGC ... aucune info...Pas de document papier évidemment, mais en ligne se serait bien.Le prix est juste Top.

Funciona muy bien.
Mucha ganancia, sonido claro, dimensiones reducidas, salida protegida contra cortocircuitos. Recomendable.Falta el condensador de salida para aislar la tensión continua de salida del amplificador. Lo tuve que añadir exteriormente. 4,7 uF/10 V.

Funziona ma l'auto guadagno é un disastro
Ha un buon chip di amplificazione ma quando scatta l'auto guadagno il noise prodotto in uscita é notevole. In poche parole se lavora con forti intensitá sonore ok, ma se il segnale é debole il rumore é sovrastante .
