Frequently asked questions
Is XLR always better than RCA?+
Not automatically. XLR is useful for balanced longer runs, while RCA is common and appropriate for many short home connections.
Can I plug TRS into a TS socket?+
Physical fit does not guarantee the intended signal. Check both device manuals and use the connection type they specify.
