20 Most Recent Anchor Audio/PA Systems: Liberty Sound System Package Microphone Questions & Answers

My personal suggestion would be to go for these repair catalogs. I know this website reliable-store.com that i used to buy them from, and they have online it was very good manual. Go ahead, I bet.

I don't have a fix for this mine does the same thing I turn on and speak and it turns off then I have to turn back on.does battery need replaced or will it play with just the ac plug.

Could be internal wiring, could that the diaphram is shot. Low Z or high Z?

I need to connect my microphone to my computer can you help me please

As I remember the Anchor has a removable metal back plate that is used to mount the volume control and 1/4" or XLR connectors. Before you start disassembling the unit....are you a qualified repair person? Other than a bad speaker, broken wire or connector there's not much "user servicable" parts inside.

I would suspect that the internal battery may need replacing as it cannot produce enough output to sustain the system at high power.
There is a lot of support available on this website (including video of how to replace the battery)

Hi please find above your manual, it maybe of some help? to obtain the schematic you would need the service manual, I have been unable to locate one? perhaps a direct approach to the manufacturer will allow you to obtain one?

Hello
i assume your running through some kind of mixer.First mark all the microphones or intruments on the mixing board...mic 1 mic 2 guitar 1 whatever your using identify it.Use masking tape and a black marker.

Next.try 1 microphone say #1 mic.Check that the mute button is not down or any presets such as echo or reverb are running through input #1.

Maybe you have a main volume on the board that is turned down? The power amp also needs to be turned up.
From what you have said it could also be a miswiring from the power amp to the board,recheck your input and output from amp to board.

you should be looking for the audio out socket from the tv as the signal is going out from the set to your speakers the other sockets are for input when connecting dvd or video into the tv. hope this helps ..A

You don't say what's at the other end of that cable. It's a player in this scenario, too.

Here is the link to the manual if you don't have one:http://www.google.com/search?hl=en&q=Anchor+Liberty+4500+PA+system+battery+power+replacement&btnG=Search&aq=f&oq=&aqi= It appears as if you have to remove the entire control panel to replace the two batteries. You probably have to use exact replacements. THe link to the company is in the manual and they can probably give you more information. Hope this helps.
