Recently picked up the H4 whilst I await arrival of the R-44 and I have to say I am pleased. The unit records very well taking a signal from the FP-33 with multiple channels.
That's very good. I seem to have lost my H4 in a Customs grab, so I may have to make up my mind again on what to buy now. And I will probably feed this unit with an external mixer, like the FP33s I already have or an SD Mixpre.
The unit does seem very 'toy' in its look and handling. Feels like I would break it if I pressed a button too hard.. but it does have XLR inputs which is a tremendous plus on this unit. The price, in comparison to other units, also played a factor
Having XLR and full phantom IS the major point in the H4. Only the Fostex, costing a bit more, seems to improve on it... but it seems quite larger too.
For that price, other recorders, like the Tascam or the Edirol R-4pro, step in as interesting options.
I am waiting for the R-44 in which the H4 will become a neat, little backup unit.
The R44 looks very interesting and more reliable than the R4, as it may stand rough portable handling better, not having an internal HDD as the latter has.
Now the question are the R-44 mic preamplifiers, as it would be a pity having 4 mic channels and not being able to use them because quality is poor.
Pity you can't put it in your pocket, as you can with the H4!
