XLR switcher based on relay switches is one of the best solutions for applications requiring low audio distortion. The relay switches with gold plated contacts ensure high reliability. The bistable relays also sustain its state during device power off state. The low insertion loss of mechanical relay switches makes the LinkBone 1-to-15 switch perfect for of low level microphone signals.

The following picture shows an connection example with up to 15 signal sources and one receiver using XLR switcher.
The LinkBone XLR switcher routes signal bidirectionally. This means that the device can be used also for signal distribution. E.g from one source to multiple signal receivers as proposed in the following connection example:
XLR Switcher connection diagram
The following diagram shows the connection diagram of internal XLR switcher network. There are fifteen ports from A to O which can be connected to common node P. The user can configure state of each individual port via touch screen on device front panel or remotely.
XLR Switcher remote control via Web interface
All LinkBone switches have an 10/100 Ethernet interface. The XLR switcher can be controlled remotely via Web interface shown on the following figure:
Additionally the device can be used for test automation by using an command line telnet interface. The list of commands supported by XLR switcher:
- off <port> – turns off the specified port
- on <port> – turns on the specified port
- reset – disconnects all ports
- mode <mode> – sets the mode of the switches
<mode> parameter can have two values:
single – only one port can be connected at the time. The device operates as a multiplexer.
multi – multiple connections are allowed to common port P.
