Apparently, some people are not happy with the sound of Metasonix modules. Which “aren't loud enough”. Or something. So, we created the R-57. It's loud enough.
It replaces the R-51 VCA. However, if the R-51 could be compared to a rose-scented roll of premium extra-soft serviettes, by comparison the R-57 is a double wall of 20-grit sandpaper. Rose-scented, even.
“This goes to eleven” my ass. This goes to heaven, and hell.
It's a dual VCA. Each channel can also be used as an instrument/mic preamp with up to 50+ dB of gain available. It can be set for a sweet and happy clean sound, it can do some meaty tube distortion, or it can be set to rip your scalp off and pound your balls into a nice sausage meat to add to your lovely omelette. Plus, the INVERT switch sets channel 2's CV to operate its VCA oppositely to channel 1. That allows the R-57 to be used as a lovely stereo panner/crossfader.
Beware. This is not intended to be a nice, neat, clean, sweet and virginal VCA. It is what it is. It has a few warts and it will not reward idiotic usage. Big hug!
• +-12v dc
• 300 mA after warmup (800-850 mA cold startup is required for 3-5 seconds).
Tiptop uZeus and "Happy Ending" power supplies cannot run the R-57 and are not recommended. Most Doepfer(tm), Monorocket(tm), Analogue Systems(tm) and other third-party cabinets should have no trouble powering the R-57.
