A/C amplifier with wireless microphone
by Patth9 - 7/26/12 8:54 PM
An A/C amplifier is plugged into the wall socket.
The amplifier has wireless options to accommodate wireless microphone.
The feedback, which is not high, high pitched, but a lower pitch, happens even if there is no wireless mic connected.
The amplifier is connected by a 1/8 connecting cord to a cell phone which holds mp3s. The wire headset microphone is also played though the amplifier along with the mp3s, that is until the feedback must be stopped.
Where is the feedback coming from? Could it be caused perhaps from a wireless device outside of the building? Please forgive if my question lacks information.
Thanks for any and all help.
