This is a 1U mains powered subrack. It houses 3 identical circuits.
Each circuit has a balanced analogue audio XLR in and out, a 2 wire circuit (on XLR) and a 4 wire circuit (balanced on XLRs). A front panel switch routes the analogue audio XLR in and out between the 2 wire and 4 wire circuits.
This unit was originally designed for one of Glensound’s customers to use alongside the GS-FW005 desktop talkback unit. Like this unit the GS-FW005 has both 4 wire and 2 wire I/O. The customer works with their OB trucks across a number of venues with pre-installed cables, some venues only have a single XLR cable for talkback and other a pair of XLRs. The GS-FW006 provides a very quick and easy solution to interafce their trucks comms system between the 2 wire and 4 wire circuits that they need to work with.
The 2 wire interface in the GS-FW006 was designed to work with Glensound products, it works with the GS-FW005 and also the GS-FW004, it can also work with the GS-FW021.
