Compatibility & preservation
Keep approved DC supply with device; check polarity/rating before replacement. Label balanced cable wiring and selected digital input; retain the non-BT model’s driver package.
- Photograph the model/revision label, connector panel, and installed/bundled accessories before service.
- Retain manufacturer manuals, original driver/firmware packages, and known-working configuration notes with the hardware.
- Use the specified signal level, connector wiring, and power requirements; connector fit alone does not prove compatibility.
