Term

an interface that adapts instrument signals for a mixer input
It also isolates the ground path between instrument and mixer, reducing hum on long cable runs.
How to verify it
Play representative content, check both channels, listen for hum and prove the spare adapter or alternate input.
Facts to record
- Source connector and signal level
- Active or passive DI and pad setting
- Stereo or mono channel count
