Review: Great Quality Item - Bought to switch between two separate mixing desks at our small theatre. One is a small simple mixing desk used by outside groups, the other a larger more complicated digital mixing desk. I'm really pleased with it and there is no discernible cross talk/grounding issues. It silently switches and does exactly what we needed it to do. It could also be used to switch between different active speakers or anything with XLR connectors.

### ⭐⭐⭐⭐⭐ Does a excellent job
*by K***T on 27 January 2026*

Using this for a high end HiFi set up where I need to switch between two sets of XLR’s into a high end headphone amp. My set up is very clear and detailed so was initially concerned about any potential negative impacts but fortunately no issues. So incredibly good value for performance and build quality.
