Theoretically - you USED Dobbly A like this: You send a vocal into it - where it is encoded and recorded to tape. The encoding BOOSTED high end as the vocal got quieter.

(ALL this was un-done when decoding on playback. This made Playback tape hiss go down when the vocal was re-EQ'd back to normal.)

If you get a Dolby A unit now - feed any signal into it - the HF eq will get boosted as things get quieter, and the louder the sound is, it will get darker. This works GREAT on acoustic guitars or pianos at times (listen to Doobie Bros gtr tracks). It's cool on room mics sometimes, maybe a little on a lead vocal, but not much. You can use it as an effects Send or run the signal right through it. To taste...

Picture a sound with dynamic EQ - brighter on the quiet parts, darker on the loud parts. Useful?
