Featured Alpine ILX-w-770 microphone echo

[Woopigsooie00]

I have a 2001 corvette convertible with the Alpine ilx-w770 and hidden Alpine R2-W12D2 in the back. I can not get my microphone to stop picking up the talker from the speakers. It is causing an echo that only they can hear.
There is no microphone gain setting that i have found yet. I have reached out to Alpine and they have no idea.My microphone is on the top of my a pillar on the driver side. Anyone have this issue?

It sounds like you're experiencing feedback issues with your microphone picking up sound from your speakers, which can definitely cause an echo effect. Here are a few suggestions to help mitigate this issue:

1. **Microphone Placement**: Ensure that your microphone is as far away from the speakers as possible. Installing it lower or at a different angle can help reduce the direct pickup of sound.

2. **Microphone Type**: Check if your microphone is a directional type. Directional microphones pick up sound primarily from one direction and can help reduce background noise and feedback.

3. **Sound Settings**: While you mentioned that there’s no microphone gain setting, check again for any audio settings related to echo cancellation, noise reduction, or similar features within the head unit's settings.

4. **Volume Levels**: Reducing the volume of the speakers during calls can help minimize how much sound is picked up by the microphone.

5. **Use of DSP or Equalizer**: If your Alpine unit supports it, you can try adjusting DSP settings or equalizer settings to reduce the frequencies that cause feedback.

6. **Installation Checks**: Make sure that all connections for the microphone and head unit are secure, as loose connections can sometimes cause signal issues.

7. **Consult Forums/Communities**: Since you've reached out to Alpine without resolution, consider checking car audio forums or user groups for shared experiences and solutions from other users with similar setups.

If these suggestions don’t resolve the problem, you might look into upgrading your microphone or even purchasing an external noise-canceling mic specifically designed for vehicle use.

You said elsewhere that you solved the problem by moving it to the pillar. Did things go south again?

Does that model have auto volume that compensates for external noise by auto-adjusting?
Maybe it's creating a feedback loop?

You're using a microphone to talk to your clients or persons on the other side. The microphone goes through the same radio OP AMP and frequencies as that of the radio. Only difference is that the microphone when turned on switches to use one AM or FM frequency. When that happens it draws excess amounts of current or volts to send the signal across via a phone line. AM or FM frequency. This excess volts blocks off the AM or FM station and uses one station from the radio to signal to the other guy on the other side. This excess volts into the radio then causes the other guy to hear an loud echo. The radio is still on, just that the microphone takes over the circuit and uses the OP AMP instead to relay the message. The phone conversation. The microphone and radio uses two different levels of ampere rating. Microphone on a higher voltage reading. This would be one cause of the echo. How to solve? Basically cannot. The volts are needed to transmit the message across and the radio also to transmit with the acquired voltage. So to solve it, place the microphone on another hotline. Voltage line different from that of the radio. Another receiver. That would do it.​

I've never seen that issue before. Have you tried turning down the speakers?

Yes i thought I did by moving the microphone from the center rearview mirror to the driver side a pillar and the volume low. But it was hard to hear them talking and the echo was still very faint on their end. The microphone i am using using is the stock one by alpine.

These are the only settings I can find for the microphone.

Maybe try knocking the mic level down so it's not picking up as much ambient noise, and speak just a hair louder to compensate?

Another trick might be adjusting the aim of the mic so the output of the speakers is "behind" it, like they do with stage monitors at live performances, to reduce feedback

Far less convenient might be swinging all audio to the driver's side speaker when making a call (unless that unit retains fade/balance settings for each input used?)

I think that T1000's directional microphone is a good idea. I think the radio itself is the issue. When reading about these issues for the Pioneer Appradio, the manual stated the unit has a logic circuit that picks up the speaker's "voice" and eliminates/attenuates it. You may want to test another phone or carrier just for shits and giggles. I know the old Cricket Wireless had lots of echo issues, so any carrier may have them as well.

The Pioneer's I've dealt with didn't have this issue. Maybe try a different mic. I have cheapie Amazon mic and don't have this issue.
