I'm not at all familiar with microphones, so sorry if this is a very simple issue. I have a Sony XAV-AX1000 headunit in my car and the standard microphone included with the kit. It's very similar to this cheap unit and has a simple 3.5mm TS output. I'm trying to replace it with a Rode Video Micro, a microphone with a 3.5mm TRS output in what the datasheet calls 'dual mono'. When I plug the Rode microphone into the headunit I get no microphone input unless I play with the positioning very lightly and leave it maybe 2mm out from being totally plugged in. It's crystal clear in that position.

How do I fix this and what portions of the barrel do you suspect are connected in this position? Would this work?

TRS

  • \$\begingroup\$ almost sounds like the Rode uses an unconventional pinout...maybe with the ring as ground? shame they don't specify that on the datasheet. \$\endgroup\$ – Tyler Stone Jan 21 at 6:33

@maxmclau The so called dual-mono configuration seems to provide a (sometimes independently controllable) copy of the monoral camera audio output, allowing this to be used for e.g. unforseen strong audio bursts during non-repeatable shot-taking. Likely (no more than that) the 3.5mm TS-TRS-adapter piece can help you out. I suspect that the TRS connection is of the conventional Tip=signal1, Ring=signal2, and Sleeve=ground/screen, with the Rode taking signal1 and signal2 as the two mono outputs. The TS configuration in your car-unit may contain shorting switches which makes a short-circuit between signal1 and/or signla2 to ground. The adapter piece you suggest may overcome this. Give it a try!

  • \$\begingroup\$ So you're thinking the TS jack is making contact with the TRS tip correctly, but then contacting the ring as if it were ground? I'll buy that adapter and report back. \$\endgroup\$ – maxmclau Jan 22 at 3:24
