THE REDCLOUD 8810U8ERS is a compact 8-channel balanced attenuator pack. It was born out of necessity for recording engineer Don Smith, aka Redcloud (Rolling Stones, Tom Petty, Stevie Nicks), who liked lots of gain on his mic pre amps but needed a simple, flexible way to attenuate the post mic pre line level signals. Plug the Redcloud into your db25 modular patch bay and patch it in anywhere you need high-quality passive attenuation.
