So I just need to replace my 4-pole adapter with a 3-pole and it should work fine?

Just check the compatibility chart, there are some differences depending on specific camera manufacturer.

I bought the SEscom cable and when inserted in my GH1 the actual plug on the 2.5mm end makes a poor connection with the GH1 socket. All other 2.5 plugs inserted are fine including adapters. Maybe I just got a bad SEscom cable, the connection is intermittent, seems like a poor fit when inserted. The alcheapo inline headphone volume control works best, go figure.

So I got my 3 plug adapter and it works correctly now. The only issue I have now is that the audio is extremely quiet and I have to up the DB in after effects. Am I right in saying that if I bought the Sescom cable it would resolve this issue?

Thanks for your helps guys

I plug the cable from Line in to the adapter then the adapter into the GH2

@spacewig thanks for noticing that! :)

@hakosuka If you are connecting one input to another input you're not gonna get too far. Usual setup would be to connect your audio recorder's output to GH2 input. Since there are no dedicated balanced outputs on consumer audio recorders, people connect headphone output to mic input. Headphone output is usually to hot for mic input, and causes recorded audio on your camera to clip. Therefore an attenuator cable, or some kind of resistor/potentiometer should be placed in between to lower the level of your audio.

I can't figure how did you succeed to record anything out of line IN.

@inqb8tr When you say headphone output is too hot, you mean charged?

I want to use my Tascam DR40 with GH3 by running a 3.5mm male to male cable between headphone/line out of DR-40 and run it into GH3 mic input. When I do this, i get a permanent hiss and the audio is not usable. DR-40 records fantastic sound but I hate post sync.... is this attenuator cable the answer?

Any help would be very much appreciated.

Well, when you raise audio level in post, you also raise the inherent noise level called the noise floor, and quality of your recording progressively deteriorates, to the point where bothering with additional audio recorder is pointless.

I am not sure how your level has gotten so low, since it should be the opposite - to high.

There are these things that strike my mind,

• volume level on zoom's headphones/line out, or input gain control in GH2 - set too low.

• bad cable / adapter, but that most likely wouldn't just lower the volume but rather introduce other unwanted electronic hiss or noises like cold solder noises or similar.

The GH3 has a dedicated Headphone socket and with the right settings you can monitor what level is actually being recorded. So I really need just a straight 3.5 to 3.5 i think.

Any suggestions, struggling to find one in the uk for under £30 which seems a bit extreme.

Any idea which Sescom cable to get for the GH3? I see they sell models for the GH1/GH2, but I'm not sure which is appropriate for the GH3.

BTW, I would be using this with either the Tascam DR-40 or DR-680. Monitoring off the GH3 has latency, (real time audio monitoring doesn't seem to work with hdmi output) so I may opt for the Secom cable with the headphone monitor tap. If anyone know which Sescom part number to order, I'd appreciate it.

thanks!

All must be ok, but sound can be distorted (due to clipping) if level is too high.
