got the replacement H2 today...1st one had only left channel on line-in.
well, i tested the line in now on the new H2 with my mics+preamp, all fine.
then i tested it with my bbox+mics =>bingo, same fault again.
seems my SP-SPSB-9 12V bbox is killing the right channels on edirol r-09 and zoom H2s......
after that i tried it 1 more time with my preamp, same fault...only left channel recording.
had no problem with this bbox on my former iriver and my sony mz-rh1 recorders.
IF my 12v bbox causes the fault, HOW the hell can that happen technically?
well, i won´t send it in for replacement a 2nd time...my intention is to use the internal mics only.....
Get a voltmeter and see if your SP battery box is OUTPUTTING DC into the right channel.
Just connect the voltmeter to ground and the output pin of the box's output connector (not connected to anything else)
It should measure at or near 0 volts. Some decks have a DC decoupling capacitor that helps protect the input from applied DC, but maybe H2 has too little protection if given too much unexpected DC power input?
i just measured the output with a connected 3.5mm cable plugged in.
the TOP-ring of the plug shows: 150mV
the middle ring shows: 80mV
Well, the plot thickens as NO help from this.
Middle ring usually the right channel, which is lower than tip-left channel voltage. Either is low enough to only cause a pop sound in the audio, never a 'smoke' problem to anything.
Do make sure everything (mic/power/preamp) is connected up and powered working to be recording, except no deck connection, just voltmeter to read output plug. If not electrical, then mechanical is most suspect.
SO MAYBE THIS IS A MECHANICAL STRESS ISSUE like R-09? Usually by wiggling a broken input you can sometimes get the audio back if holding plug in some position. Maybe try this with phones on?
If you can hear the audio come back momentarily in the phones while in REC/standby, then mechanical failure (PCB board/input connector) is most likely.
I am also 'proud owner' of a H2 deck and never had a problem in just over a month, maybe only because
still inside an unopened box waiting for review time. Now you got me thinking 'somebody' should open one up and see what's up?
Just maybe the input jacks are like R-09 just 'waiting'
for an excuse to break?
Suggest seeing this through with
getting another trying not giving it an excuse, like using straight in plugs or long handled right angle types, especially with stiff cord.
And is there more gluing down input jacks in our future for the opportunity to own a
really cheap deck
that still works?
Or is the specter of another parade of broken jacks
just a mirage. Say it's so!
Roland's refusal to get the correct jacks installed after more than a year seems intention to making decks with break-away jacks a good practice!
And now maybe Zoom H2 has followed to spoil the party.
This would be more humorous to me, but because I think these tiny, inexpensive decks are fun to use; more or less produce very satisfying quality audio especially with enhancing accessories,
but shouldn't we be expecting most of us having two years trouble-free ride?
