The BLACKBOX RECORDER with Balanced i/o enables audio capture via a mixing console with balanced insert points or direct outputs. The three lower 25-way female D-type connectors are used as balanced inputs and the three upper 25-way female as balanced outputs.
In the same manner as the Unbalanced model, the BBR1B loops the inputs directly to the outputs via relays when in record or stop so that even a power failure on the BBR cannot affect the audio through the PA. Other BlackBox Recorder features remain unchanged.
The Balanced i/o interface uses high quality balancing receivers and transmitters and has been designed specifically for the BLACKBOX RECORDER to be fully transparent.
