How can avoid interference of radio stations in the amplifier?

There could be several potential causes for the issue you described with your Kustom Quad 100 Dfx amplifier. Here are a few possibilities to consider:

1. Power issue: Check the power source and connections. Ensure that the amplifier is receiving stable power without any fluctuations or interruptions. Faulty power cables, loose connections, or inadequate power supply could cause the intermittent cutting out and restarting.
2. Speaker or speaker wiring: Examine the speaker(s) and the wiring connecting them to the amplifier. Loose or damaged speaker cables, faulty speaker connections, or even damaged speakers themselves could lead to the intermittent behavior you're experiencing.
3. Overheating or thermal protection: Amplifiers often have built-in protection mechanisms to prevent overheating. If the amplifier is overheating, it may shut down intermittently to cool off before powering back on. Ensure that the amplifier has proper ventilation and isn't placed in an environment where it's prone to overheating.
4. Internal component issues: There might be a problem with internal components such as transistors, capacitors, or resistors. These components can sometimes degrade or fail over time, causing intermittent issues like the one you described. In this case, it may require professional inspection and repair.
5. Other external interference: Consider any other factors that could be causing interference with the amplifier. Nearby electrical devices, radio frequency interference, or even faulty instrument cables could potentially disrupt the amplifier's performance.

It's worth noting that troubleshooting electronic devices can be complex, and it's often best to consult with a qualified technician or reach out to the manufacturer's support for assistance. They will have the expertise and knowledge to diagnose and resolve the issue specific to your amplifier model.

check that your aerial is in good condition and is properly installed, if you do not have a signal amplifier try fiting one, it may make a difference.
It may be that you are experiencing RF interference from a radio source, something transmitting on the frequency that your signals come in at.
I have the same problem with buses communication with thier controllers at stations, keeps cutting out my signal....A good aerial solved it

follow this steps and fix it. God bless you

blem: I get noise on my car audio system that disappears when I turn the car off.
Possible Cause
Suggested Solution Alternator or ignition noise is being picked up through the power connection. Install a 12-volt noise filter between the power tap and the power input on your car audio. Back to the Troubleshooting Index Problem: The sound distorts at high volume when I play the radio in my car audio system.
Possible Cause
Suggested Solution The radio wattage is too low to drive the speakers. Use a car amplifier to increase the radio's power. Replace the speakers with ones which match the radio's output. Back to the Troubleshooting Index Problem: My car radio only get one station.
Possible Cause
Suggested Solution There is a problem with the wiring. Check the antenna circuit and rewire if necessary. There is a problem with the antenna. Check the antenna and replace if necessary. There is a problem with the radio. If you received more than one station with your previous system and you have already checked the wiring and the antenna, either replace the radio or send it to a service center. Back to the Troubleshooting Index Problem: My car radio keep running hot and blowing fuses.
Possible Cause
Suggested Solution The wires to different speakers have been combined rather than run separately. Make sure that each of the speakers has 2 wires run to it. Combining speaker wires will cause this problem. Back to the Troubleshooting Index Problem: I lose my station memories in my car radio when I turn off the vehicle.
Possible Cause
Suggested Solution The tuner memory wire may not be connected properly. Connect the yellow wire to your vehicle battery's positive (+) terminal or to a fuse that provides a continuous source of 12 volts. This connection provides continuous power for the clock and tuner memory when the ignition is turned off. Back to the Troubleshooting Index Problem: The amplifier stays on for a few minutes, then shuts off, then comes back on, then shuts off again.
Possible Cause
Suggested Solution It is overheating due to power issues. Check your power ratings to be sure they match the amplifier's specifications. There is a problem with the amplifier. If the power ratings are correct, the amplifier needs to be sent to a service center. Back to the Troubleshooting Index Problem: When using two amplifiers, I lose the right channel on one amp.
Possible Cause
Suggested Solution There is a problem in the sound system or wiring. Try swapping amplifiers or bypassing that amp. If the problem persists on the right channel on both amps, check the wiring and sound system. There is a problem with the amplifier. Replace the amplifier that displays the problem or send it to a service center .

You can get a converter like this one.

It's a simple solution and it works.

Complain to the station running the loud adverts!

Try plugging the output to an amplifier that is turned lower and reduce the volume of the TV to almost nil. The amplifier re jigs the recieved waves through a filter better than most tv's.

You can boost the signal range of a WiFi computer network in several ways: Answer:

• reposition your router (or access point) to avoid obstructions and radio interference. Both reduce the range of WiFi network equipment. Common sources of interference in residences include brick or plaster walls, microwave ovens, and cordless phones. Additionally, consider changing the WiFi channel number on your equipment to avoid interference.
  
  
• upgrade the antenna on your router (or access point). WiFi antennas on most wireless base stations can be removed and replaced with more powerful ones.
  
  
• add another access point (or router). Large residences typically require no more than two APs, whereas businesses may employ dozens of APs. In a home, this option requires connecting your primary wireless router (access point) to the second one with Ethernet cable; home wireless routers and/or APs don't normally communicate with each other directly.
  
  
• add a bi-directional WiFi signal amplifier to wireless devices as needed. A WiFi signal amplifier (sometimes called "signal booster") attaches to a router, access point or Wi-Fi client at the place where the antenna connects. Bi-directional antennas amplify the wireless signal in both transmit and receive directions. These should be used as WiFi transmissions are two-way radio communications.
  
  
• add a WiFi repeater. A wireless repeater is a stand-alone unit positioned within range of a wireless router (access point). Repeaters (sometimes called "range expanders") serve as a two-way relay station for WiFi signals. Clients too far away from the original router / AP can instead associate with the WLAN through the repeater.

What you are hearing is ground loop interference. If you have an aftermarket headunit/amplifier this is a common occurrence. A ground loop isolator in line with the low level amplifier inputs should solve the problem. Otherwise, it may be a malfunction of the stock cd unit or amplifier. BMW used a balanced input on some of the stock amplifiers, which would make ground loop interference all but impossible.

Sounds like an internal prob within the reciever, since recievers have radio tuners in em, maybe a prob in the input switching in it. I assume you are running unbalanced rca cables out of the dvd player into the reciever as it probably doesn't have balanced input capability, unbalanced lines are susceptible to R.F.I. ( radio frequency interference ) but I doubt if that's the problem here unless maybe you are running very long cable lengths from the dvd player to the reciever. Try using a different input and see if the problems still there, can use any input other than phonograph really as they are all line level inputs.

I would use sheilded wire on the mic with the least amount of cable. You can relocate the pre amp with aluminum foil wrapped around the pre amp. also turn the gain on the mic down as to eliminate any interference from your strong radio station nearby. Randy
