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. The unit can use the same high quality D-type cables as for the unbalanced BBR1, but these are not supplied as there are too many different types of termination (1/4" TRS, XLR male, XLR female, 25-way D-type, etc.).
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.
Balanced i/o via 6 x 25way D-sub connectors. Lower row - inputs; Upper row - outputs. (TASCAM analogue format, cable looms not supplied)
