Crescendo 8
Eight-Channel Microphone Preamplifier with 120V technology
Crescendo 8 combines the precise sound that German Rundfunk-Technik is famous for with the innovative SPL 120V technology. The internal operating voltage of 120 volts allows Crescendo microphone preamplifiers to break completely new ground. This results in microphone preamps that sound detail-rich, vivid and equally honest.
Crescendo 8 lets microphones shine in a whole new light – because they have never been amplified like this before.
The Undistortable
Thanks to the SPL 120V technology, it is almost impossible to overdrive this microphone preamplifier.
Crescendo 8 is an eight-channel microphone preamplifier with 120V technology.
All eight channels feature the same range of functions. Besides phantom power (48 V) for condenser microphones, polarity reversal and a PAD switch, they provide the possibility to adjust the VU meter to display very high levels. The gain can be adjusted comfortably and precisely via a high-quality potentiometer. Two outputs per channel allow the signal to be sent to two different devices in parallel. In addition to the extensive feature set and the outstanding technical characteristics, Crescendo 8 convinces with a sonic authenticity that is second to none.
