Know before you buy
No, the Relay Xo is a switcher, not a splitter. It routes your signal to either output A or output B, but it cannot send the signal to both destinations simultaneously.
No, the unit does not support phantom power. If you are using a condenser microphone that requires phantom power, you will need to use an external preamp or a mixer to provide power before the signal reaches the switcher.
The Relay Xo is designed to work with a standard latching or momentary footswitch, depending on your specific routing needs. It provides a simple, reliable way to toggle between your two outputs hands-free.
The Relay Xo is built with a high-quality, passive signal path designed to maintain the integrity of your balanced audio. Because it is an analog device, it does not add digital artifacts or coloration to your signal.
While the unit is designed as a 1-in, 2-out switcher, it can technically be used in reverse as a 2-in, 1-out selector. However, please note that switching between active signals may cause audible pops or clicks depending on your gain staging.
