Learn how the Rode MINIJACK to XLR adapter with power convertor lets you connect 3.5mm mics to XLR inputs and fix common power and wiring issues.
Quick answer
Use the Rode MINIJACK to XLR adaptor with power convertor when you need to plug a 3.5mm mic into an XLR input that provides phantom power. It converts 12–48V phantom power down to 3–5V plug-in power, so mics like the VideoMicro or HS2 receive the bias voltage they need without a separate battery.
Why a plain 3.5mm-to-XLR cable often fails
A simple passive cable only changes the connector shape; it does not supply plug-in power. Many 3.5mm mics need a small bias voltage to operate, so they stay silent or very weak when connected to an XLR input that only offers phantom power.
The Rode adaptor solves that by converting phantom power down to the 3–5V range those mics expect. If your XLR source cannot provide phantom power, the adaptor has nothing to convert, so the mic will still not work.
When the adaptor is the wrong tool
If your 3.5mm mic is a dynamic mic that does not require plug-in power, or if your XLR input has no phantom power, a passive adapter may be sufficient and less expensive. Also, the adaptor does not convert a mono mic into a balanced XLR signal; it only handles power and mechanical connection.
For critical recording, check that the mic's plug-in power requirement falls within the 3–5V range the adaptor provides. If your mic needs a different voltage, this adaptor is not the right match.
Diagnose your connection problem
- Symptom: No sound at all: Confirm the XLR input is supplying phantom power (12–48V) and that the adaptor is fully seated. Check that the 3.5mm plug is pushed all the way into the adaptor's socket. If phantom power is off, turn it on; if it is on and still silent, test the mic on another device.
- Symptom: Very low level or distorted audio: Verify the mic requires plug-in power in the 3–5V range. If it does, the adaptor should work; if the level is still low, check the recorder's input gain and the mic's own sensitivity. If the mic needs more than 5V plug-in power, this adaptor is not suitable.
- Symptom: Hum or interference: Ensure the XLR cable is balanced and in good condition. Keep the adaptor away from power cables. If hum persists, try a different XLR input or cable. If hum continues with known-good cables, the issue may be the mic or the adaptor; test with another mic.
- When to stop and choose another option: If your XLR source cannot provide phantom power, or your mic requires a different bias voltage, do not use this adaptor. Instead, use a powered 3.5mm input or a dedicated wireless system. Match the adaptor to both the mic's power needs and the XLR input's phantom power capability.
Product facts
- Rode MINIJACK TO XLR ADAPTOR WITH POWER CONVERTOR: The VXLR+ is a 3.5mm female TRS socket to male XLR adaptor that converts 12–48V phantom power down to 3–5V plug-in power. This lets you power Rode on-camera mics and self-worn mics like the HS2 from an XLR input without extra batteries.
