I tried another computer with the same results. I must have one of the first version 2 to roll off so there may be some growing pains. I will give parts express a call and see if tech support can help.

Thanks Bob

Bob,

Just out of curiosity did you apply the cal file once you downloaded it?

I apologize up front for the question but just checking to see, thanks.

Bob,

Thanks for the reply.

Does that file you downloaded show your mic's serial number in the name? Can you make a copy of that cal file and then go into the copy and see your mic's serial number anywhere? Thanks.

Thanks for the help on this. Here are the first few lines of the text file. My serial number is listed on the first line. Bob

Bob,

Just a few more questions for you.

1) Is this a V2 mic or a recalibrated V1? I am thinking the V2 based off of this statement I just set up my new Omnimic but just want to make sure.
2) What OS are you running?
3) What does the Omni show as in the Control Panel (under the Sound)?

James:

1) This is V2.
2) Window 7 64 and 32 bit (two machines tested)
3) It shows as a microphone under the recording tab ( I did set the format as 2 channel, 16 bit, 48000 HZ) as instructed by the software.

Thanks

Bob,

Unfortunately I am out of ideas as of this point as it appears you have everything setup correctly. Hopefully Bill will see this and have some ideas.

I have checked my TXT file and the sens factor = -4.083, maybe this might be the cause, yours is -45.65, big difference?
post #1542 of 2086
Anyone have a working link to the v3.10 upgrade?

PE's http://www.parts-express.com/pe/show...number=390-790 is broken

thanks

Ok, I checked a few serial numbers above and below mine and all had the high sens factor. I will check with PE, someone must have made a mistake. Although this also gives reason to question every number in the file.

Thanks

Update: I contacted PE and they are aware of the issue, Dayton is looking into it. Hopefully will get a response in a day or two. This might mean another round of recalibration for early adopters of version 2.

Anyone else get a similar email from Parts Express:

"We discovered today that due to a misunderstanding on the side of our factory, your microphone was calibrated to a standard not intended to be used with the V2 software. We imagine you are eager to use your new OmniMic V2 and have shipped a no-charge replacement today. Since your original shipment (invoice #xxxx) is in transit to you, we requested Fed Ex to intercept delivery and route the shipment back to us. In the unlikely event your original shipment is delivered, just let me know and I will send you a postage paid return label.

I hope you will accept our apologies for any inconveniences or disappointment this issue may have created for you."

I have not received an email yet but that is good news that they are taking care of the problem. Too bad for PE, all the QC problems with the last manufacture and then this problem arises during the first few shipments with the new. I will have to give them another call in the morning to see if mine is on the way. -Bob
post #1549 of 2086
All:

First, thanks for your support of the OmniMic system. We appreciate your comments, suggestions, and discussions regarding the applications and use of the system.

As some of you know we made a recent hardware manufacturing switch from the original OmniMic to the recently introduced OmniMicV2. Unfortunately, during the changeover it appears the first batch of microphones were calibrated using a procedure that is not intended for the OmniMicV2 system. We know you are eager to use your new OmniMicV2 so today we are shipping replacement correctly calibrated V2 microphones. Since you may receive two OmniMicV2 please call Parts Express at 1-800-338-0531 so we can verify by serial number which is the right one. We will also be sending a postage paid label for returning the miscalibrated OmnimicV2 We apologize and again want you to know how much we appreciate you and your patience as we correct this problem.

Thank you.

We'll take care of you Bob, just give us a call. We feel that even though we had this initial problem, the hardware and software are solid and function very well together.
post #1551 of 2086
Rich,

Does this in anyway affect the V1 models that were sent back in for a recal? Only asking since I had just sent mine in on the 5th and received an e-mail today that states it is shipping back to me. I am thinking the V2 came into you guys in that manner and it will not affect the V1 but just making sure. Thanks.

Hi All:

I removed the calibration file on my OM-V2 and it works much better for now. Certainly not accurate but at least I can begin to experiment with it while waiting for the fix.

I started with Frequency response using track two sine sweep and I placed the mic in my normal sitting position. I was using two bookshelf speakers with the sub on. Two questions:

1) With each iteration of the sweep, the FR seems to jump around +-2db or so at all frequencies although more in the lower end. Is that normal?

2) I recently upgraded speakers so I decided to see the difference in FR. The attached graph show a plot of both sets. I was surprised how similar the plots are. I expected them to be about the same under the crossover (60Hz) but I expected more differences above. Do small differences translate into large differences when listening? In my listening tests, I found these two sets of speakers more similar than different for sure.

Thanks Bob

wait till u have a working mic.
post #1555 of 2086
I am interested in buying this but should I rather wait until these mic issues are resolved ? I live in South Africa so if there is an issue it won't take a few days to resolve. Just a little apprehensive given the mic story.

Hi Bob good to see you are getting the mic sorted. What sort of connection is on your V2 mic, is it normal USB or Micro USB?

Try increasing your volume, around 75db. This will make the graph more steady due to noise (background). You might think it is very quiet but noise to the ear can be deceiving.

The new mic might give you a different reading, but this anyway.

Normal USB. I will try the increase in volume. Thanks Bob

They should have this sorted out for new orders but I would wait until a few memebers give positive results considering you are from South Africa.

Understood...I would ask PE to calibrated the OmniMic before shipment. BTW, my wife was born and raised in Johannesburg and recently, we went to a wedding in Cape Town...a very, very beautiful country.
