Here's what Golden Age Project say about the Active Ribbon Microphone
The R 1 Active MKIII is a very cool mic that combines the best of two worlds; the warmth of a ribbon and the stability of a F.E.T. buffer ampilier. This means that you can use the R1 Active MKIII with long cables and virtually any pre-amp featuring 48V phantom power.
A clean and clear sound, yet warm and punchy is what the R1 Active MKIII will deliver in most cases. We love it on drums, as an ambience mic or in pairs for O.H. pickup, but it sounds great on most instruments.
The R1 Active MKIII is in fact a very versatile mic even suitable for some sensitve vocal recording! And even more so now when the mk3 version includes switches for low cut and 10dB pad.
