Hi Everyone.

My old Fender Passport seems to be giving up the ghost. :cry: I use it in my bar for Karaoke and the small house band we have. Few issues over the years but patched up and served us well.

For about a month I hear this odd sound coming through. Like a Poing. Actually a bit like a deeper version of the sound you get from the old Pong game.

It didn't happen very often and I honestly thought it was an artifact on a coupe of the Karaoke tracks I had. Then last night it was very frequent. I am no technician but it really sound like some kind of discharge happening within the unit. Maybe a capacitor or a transistor ????? releasing a charge.

Has anyone experienced this? does anyone know exactly what it could be? I have someone who can take a look but need a few pointers.

Thanks

Staylong

I've never heard anything like this from either of my Passports, but I wonder, do you have the reverb cranked up? For Karaoke, I could see that as a possibility. Just as a step in troubleshooting, when it's happening, you might try turning the reverb up and down to see if that makes a difference.

If reverb is important to you, it might not make a difference in terms of thinking the unit needs repair, but at least you'd have a head start on figuring out what is or is not involved in the problem. If not the reverb, then tweak the EQ and see if that makes a difference. Do the LED lights that indicate signal level do anything in response to the sound? Does it only happen at high input volume levels? Do the individual channels turn red when this happens?

If the latter is true, try turning the input volume level lower and turn the master volume higher. Basically, you need to find which knob or switch makes the problem better or worse. Without that, troubleshooting will be really hard.

Thanx for the response.

Sad to say its not that. I don't use the reverb for Karaoke as I go from a separate small mixer into a line in on the Fender. No effects on Fender. Everything centre. No extra bass nothing. Been using it like this for years. None of this poing sounds.

I also use for small duo/band which is basically keyboard in - no effects, guitar own effects and three vocal mics with small reverb.

Both Karaoke and band set-ups used for 6 Plus years. Same settings.

It's really only last couple of months we started to hear this odd sound every so often. Was two three times a night. Over say four hours. Now the sound is coming every four minutes so its a definite deterioration and that is why I am thinking a component.

Lucky for me I have just brought a new system in. With an Allen Heath Zed mixer with effects and two QSC K10's. It will kick butt. So I am setting that up tonight and the Fender will be honorable retired after eight years of good service and abuse.

In saying that I want it retired working for use in the odd party or BBQ.

So solutions still sought.
