Headphone Compatibility.

[ivanll]

My Gold Bug Pro is NOT compatible with the AUVIO 33-283 Portable Digital Wireless Stereo Headphones.
Loud sound at switch on, then it drops to a very very low audio.

However the headphones work real well on my F75 and other detectors,................. just not on the GB-Pro.

There is a impedance mismatch between the auvio transmitter and the GB Pro. There is one of two options to make it work. You either need to increase or decrease the resistance between the detector and the transmitter. Some people have used an in line volume control to increase the resistance to get theirs to work(Radio shack should have these).
My Auvio 33-283 did not initially work for either of my two older Garretts or my 1266X. increasing the resistance did not work for my old analog detectors. I had to reduce the resistance which I did by adding resistance in parallel(which reduces the total resistance) I made a 1/4" to 1/8" adapter and placed a resistor in parallel between the tip and ring(the two connections on the plug) Now my headphones work with all 3 detectors

Info much appreciated, Thank you.

A little experiment is coming up.

ivanll, I'm glad that it worked for you...This works on many older detectors especially analog machines. If you've tried using an in-line volume control and that didn't work.. this should..

How much resistance are you applying in parrell on the plug?
