Recording Studio Patch Bays
The patch bays in the recording studios are a combination of Miniature Bantam and B-Gauge, dependent upon what the connections are being used for.
In general, the larger B-Gauge connections are used for microphone tie lines and pathways that may carry 48V phantom power. Connections between outboard devices within a studio are carried on Miniature Bantam, which prevents accidental cross-connection and increases the number of devices that can be connected to a single patch bay.
Technical Information
B-Gauge
To avoid confusion, please note that B-Gauge is often referred to as 'GPO', which is a reference to 'General Post Office'. These type of connections were routinely used in telephone exchanges and switchboards, which were run by the Post Office before the existence of British Telecom.
