SPL Crescendo 8 - Eight-Channel Microphone Preamp
SPL Crescendo 8 - Eight-Channel Microphone Preamp
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.
Built-in Output Splitter
All eight microphone preamps have two parallel outputs each. This allows the signal to be sent to two different devices in parallel. One output each is available as XLR line output. The respective second outputs are available as a DB25 jack. These can for example be ideally connected to a multi-channel AD converter, with the for this kind of device type typical DB25 input. An additional external signal splitter for back-up systems during a recording session is therefore no longer necessary.
