Live 24 Channels Recorder 

Based on JoeCo's award-winning BlackBox Recorder technology, the new BlueBox Workstation  Interface Recorder range is a new concept in recording. There are currently two models in the BlueBox range: the BBWR24MP and the BBWR08MP, the former providing 24 channels of switchable mic/line inputs and the latter providing 8 channels of mic line input and 16 channels of dedicated balanced line inputs. The mic channels on both units incorporate JoeCo's clean high-quality mic preamp designs. In a studio environment the BlueBox can be used as a low latency audio interface device providing a full 24 channel interface at 24bit/96kHz both to and from a workstation simultaneously utilising the on-board recording function as a backup device. For live work, the unit's in-built high-quality mic preamps can be used as a stand-alone, live, multi-channel audio acquition recorder using the low latency 24 channel, 24 bit, 96kHz workstation interface to a computer for backup recordings.
