This is a kind of noise reduction dolby for magneto bands or tape deck.
The noise is reduced by more than 30 db with a reserve of 10 dB overmodulation.
With a good tape deck, you can compete with a dynamic cd. With a magnetic strip of the kind Revox, we get to 110 db which is higher than the cd and for purists, it remains on pure analog!
It is a device that encodes and decodes the signal so it is imperative to read with the camera recording coded DBX II.
Make sure it works before buying it because an old one that almost nobody knows how to repair or adjust them properly.
Manulen clear and simple configuration but in English.
Is the DBX and it works very well as all the DBX if properly adjusted. No
VU meters, but present on the 224x.
It's old, so when it fails, it's super hard to repair.
