SG Intl - TV Globo, Brazil
This is a custom 4-way splitter with 56 inputs and no returns. Outputs are via Whirlwind W4 MASS connectors. The Main and Direct outs are both direct from the XLR inputs. ISO 1 and ISO 2 outputs (see below) are isolated via Whirlwind TRSP-2 transformers.
Each channel features three switches for lifting the ground to each split output.
This is part of a system designed and built for TV Globo in Brazil.
The isolated outs are color coded to match their respective fanouts by applying colored laminate around the W4s.
