what to do cordless phone amplifier problem

Hi,

I have mono amps where one of the two mono amps has intermittent interference from static which comes out of one of the speakers. I did a variety of tests to rule out as the source of the problem: the speakers, the preamp, the cd player, the speaker cable, and the interconnect cable. I also tried grounding the amplifier as well as power conditioner. I sent the amplifier back to the manufacturer and the manufacturer says the amp works fine.

Today, my wife tried to use the cordless phone in the downstairs bedroom and instead of getting a dial tone she got the sound of my stereo blaring through the cordless phone receiver. She then noticed that this same thing happened on the kitchen cordless phone too.

I assume that the problem with phone picking up my stereo signal is linked to my intermittent static issue.

Since its happening on two separate cordless phones on two different floors of the house(same phone number though), should I be calling a electrician or the phone company to check out the phone lines?

The problem does not occur continuously. The phenomena lasted for about 10 minutes.

Any thoughts?

KennyT,

I did switch the amplifier but the static remained coming out of the same speaker. When I sent the one amplifier back to the manufacturer, in the interim I ran the remaining mono amplifier and an old mono amplifier I had lying around and never had the static problem. Now the mono returned from the manufacturer and the problem returned.

All the problem phones are 5.8GHz.

So do people think I should call a electrician or someone to look at the phone wires in the wall?

This is not your first post regarding your static problems. I have no idea whether it's related to your phone system or not, but I would recommend that you contact a few local recording studios and find out who does their electric work and have your house wiring thoroughly inspected. Most electricians haven't a clue about audio equipment. Maybe an electrician who has worked on studios will at least be more open to your concerns.

Have you tried unplugging the A/C on the phones? You may need a line conditioner or better ground to eliminate this. Are your phone plugs 3 prong? Try a cheater (3 prong to 2 prong adaptor) to avoid ground loops. Your phone system may be grounding itself in the same place as your electricity???
Even relocating the phone bases to the other side of the house to utilize circuits on the other side of you fuse box may do the trick.
My electrician would be lost if you called him with this problem...

Good point. If you unplug all your phones from the wall power, and you still have this problem, then the issue has nothing to do with your phones.

Last year, we had a problem with our phones (both cordless and corded). We would often not have a dial tone, and on more than one occasion would pick up only to hear neighbors conversations (even on wired phones). After several calls to our phone provider they agreed to come out--turns out there was a problem with the common connection for the cluster of houses that was related to a bad ground of the phone circuit. Since your issue seems "internal" it might be worth just checking the integrity of the connections between your house and the incoming phone interface. Ours is outdoors and subject to the elements which is never a great environment for connections.
