QA490 for over-ear headset

1

Hi,

I’m interested in the QA490 in-ear monitor tester.
But we need to test over-ear headsets.
Can you tell me if you have an adaptor available, or application note, or recommendation to test this kind of headsets?

Thanks,
Leo.

Hi @LeoSandler, there isn’t currently a project planned for over the ear testing. I don’t think an adapter would work because the coupling would likely introduce its own frequency response that would be hard to separate from the DUT.

OK, thanks.
I would like to order one QA490.
Can you tell me if it is available for ordering? and how I put an order.

Thanks.

Hi @LeoSandler, like everything else, the QA490 is currently backordered due to silicon shortages (again, the SN6505B part among others).
