Summary

[edit]
Description
Italiano: Circuito ad altissime prestazioni Ibrido nel Preamplificatore Microfonico Ant-Telefunken V672D . La scelta di affidarsi alla tecnologia dei Circuiti Ibridi nasce dalla necessità di disporre di un modulo dalle prestazioni e dall’affidabilità veramente eccezionali. La tecnologia dei Circuiti Ibridi utilizza infatti un substrato ceramico (base per i componenti) sul quale vengono depositati, per serigrafia e successiva sinterizzazione, materiale conduttivo, dielettrico e resistivo che nel loro insieme formano la parte passiva del circuito. I resistori serigrafati vengono tarati al laser per ottenere con grande affidabilità e precisione (sia in rapporto che in valore assoluto) qualsiasi valore desiderato. Sulla base ceramica vengono montati i transistor SMD. Al collaudo finale è possibile effettuare anche una Taratura Funzionale al laser del circuito stesso, questo aspetto evita l’utilizzo dei trimmer e garantisce così una maggiore stabilità nel tempo del dispositivo
English: The V672D is the 2-channel version of the V672a multi purpose amp. It was designed by Telefunken in the 1960s and built by Telefunken and later (after Telefunken had quit broadcast equipment business) by ANT in many versions. The ANT V672D is a dual channel discrete and transformer balanced amp with 43dB of gain for each channel. In microphone preamp configuration it can give up to 60dB of gain with linear frequency response. Most audio components are placed on a hybrid IC (center).
