Claus,

I did some testing in the last few days lying timecode down as audio via the external mic input.

The inability to turn off auto gain or set the input levels manually was a huge pain, and almost stopped this working.

There are some other options if you want headphone monitoring.

1) Go out from the a/v out into a dvd player mounted on the side with headphone out. This is a cheap larger screen option for tripod work, and then you have headphones.

2) Get a rolls PM50sOB. Might be overkill for what you want, but you can use to plug headphones into the line level out. $66 isn't too bad though...

I use a XLR-BP Pro to take xlr external mics (onboard and boom) into the 3.5mm, but it does not have a headphones jack on it.

Incidently the only device I found that seems to power the external MZ-48U whilst in this xlr-bp pro (which does not supply it power) was the all601 lanc logger. Total overkill for normal use, but nice bonus if you are laying down tc.

I notice the new models (not the hd7) have a headphones jack :). They are not as good as the hd7 in many respects for my use, so wouldn't swap because of that.

For info the levels on the hd7 and the lights represent roughly the following (based on taking outputted files into soundtrack pro, and checking the levels whilst playing).

Lights - level
5.5 - -23db
6 - -21db
7 - -18db
8 - -16db
9 - -13db
10 - -6.2db

For me to get my timecode laid down between -20db and -10db based on my input from an ALL601 set to -24db was 5.5-6.5 lights. So it seems that is the real sweet spot of the range.

Cheers,

Kieran
