Sound quality of the nano headphones output

Is it just my unit, or does everyone hear a lot of modulated hiss (the kind of noise similar to weak FM broadcast) when monitoring both live HD-SDI embedded audio (from EX1), and playing back clips recorded on the nano?

This is not present in the clips' audio when put on the NLE timeline.

I don't. Well, did not the couple times I used it with headphones.

I can't seem to be able to find it in the manual; how do you adjust embedded audio level during recording?

I mean - on headphones monitoring, that is...

Piotr,

Use the up and down arrows on the unit's interface. Not documented (as far as I know) but confirmed by Dan a couple of weeks ago.

I thought I remembered Dan mentioning the up/down arrows, so I tried those first - don't seem to work.

Dear Dan,

Could you please remind me how one can attenuate the headphone output level during recording?

Also - playing with the buttons - I noticed that pressing the Play button for a couple of seconds, toggles "Autoplay" mode on/off; just what this mode is?

The headphone volume is full on, always. The level can not be adjusted.

If that's indeed the case, then it sounds like an urgent feature wish for the coming firmware releases, Dan!

I record classical music performances, and the current loudness of my headphones is definitely too high for even trying to use in an auditory....

I've already verified this is correct. I was advised to get myself an inline headphone volume control

Dear Piotr and Aaron,

In the Flash XDR, the volume is not currently adjustable. This is expected to change.

In the nanoFlash, the volume is adjustable.

Dear Dan,

I'm currently on the Public Beta, and the arrow buttons do not adjust the volume.

How is it supposed to work?

Hi Piotr. I assumed that since the volume is stuck on full output for the XDR, the same was true for the nanoFlash. I've always thought the features between the two units were identical. Sorry for not verifying this specifically for the nanoFlash.

From now on, I'll leave the nanoFlash questions to the guys who actually have one, since these units obviously have more differences than size and a couple CF slots.

Dear Aaron,

As far as I know, this is just a temporary difference.

The audio circuitry between the nanoFlash and Flash XDR are quite different.

Some time back, I asked if we could implement the headphone volume control on the Flash XDR. The answer was yes. We just have not done it yet.

Hey Dan,

My audio guy is complaining that he can't turn the nano headset volume down low enough. He is using those ubiquitous Sony headphones (MDR-7506?). Anyone else seen/heard this?

Thanks!

Yep - confirmed with my Sennheiser HD 25-1 mk II; definitely too loud!

Dan - this definitely is a problem that needs fixing; recording quiet events like e.g. solo guitar recital needs audio monitoring, but its loudness must be adjustable so that I'm not disturbing the audience.
