What frequency is this? H8?

We have 12 of these in several frequency ranges - H9 and H10 mostly. When you purchase your system, it should allow you to select the frequency range that you want. None of our mics/instruments in our ranges have been affected by interference from outside sources, which is typically one of the biggest reason to select a specific range. Best of luck to you. Let me know if you have any other questions.

Is the j10 compatible with my beta 58a @ 589.025mhz? thanks for confirming.

Hi Rick,Yes, Shure states that this operates at the J10 frequency range (548-608 mHz). This should work for your setup.If this was helpful, please consider purchasing from us. We can help with support after the sale as well. We have it in stock and ready to ship. - Pixel Pro Audio

when you order this receiver I supose that we will receive the adapter also??

Yes... It includes the power adapter.

Is this receiver compatible with the PG58 wireless hand held mic?

Am using the PG58 with BLX2 Transmitter on H8: 518-542 MHz with a BLX-4:H8 receiver. It works very well. No problems at all.
