Is there a SIP paging adapter that has 500ohm output

General Help

I am trying to hook up to an existing paging system. The amp has a 500ohm input for the Tel line. Is there a way for me to a way to output to that?

Thank you

600ohm is normal.

The cyberdata model has it.

Thank you. I had original purchased this fanvil, but it looks like its only 4ohm output http://www.fanvil.com/Support/download/id/86.html

You can also use impedance matching gear like this.

Try connecting the Headset output of the Fanvil to the input on your amp. The 32 -> 500 ohm mismatch shouldn’t affect anything and the 1.2V output is safe for the amp.

If it works but you get hum, try also connecting a ground wire between the two devices. Fanvil has a grounding screw; I assume that your amp has similar.

If you still have hum, try connecting the Fanvil Headset output to an RCA input on your amp, if it has one. + to center pin, - to shell.

If still no luck, post results.
