Crackling audio / quiet on left side

I get fainter / tinby / crackely audio out of the left speaker channel, However when CD Direct is on the sound is pretty good (this must be bypassing the dodgy circuit, also the audio crackles when you turn the bass/treble adjust so I'm guessing it's to do with this circuit. I tried to get this repaired professionally, but the agent I was using was unable to get service info from the manufacturer please Help... UK, Surrey / London area, Thanks

Hi Gareth - I saw you answered a question on an ARM 32-bit Cortex V3.00 barcode scanner earlier and I'm looking for someone to help use one to scan barcodes into a spreadsheet. Sorry for answering off-topic but I'm new to fixya and wasn't sure how to get in touch!

Left speaker not working, system crackles if left side is active, alright when left side shut down.

Get a meter and check the resistance on the speaker. Looks like a speaker may be blown but with the description of the crackle noise from the slide controls you might have a bad pot in the unit or the pot has come loose from the board. This could explain why the speaker blew out

Left speaker is very quiet

This may be a capacitor problem, evaluate and replace if bad.

Crackling and scratching

Your speaker may be blown take out the speaker that is hooked up and attach another one a house speaker would even work, and i bet your speakers are blow if not check the wires and make sure you have them connected properly if not check the wires going to the harness and to the speaker and if not i think the radio is fried you can also take a long speaker wire take radio out the dash and run it to the speaker if it does still the radio is fried take it back before 90 days is up!

The sound on one of my speakers is breaking up and crackling terribly, especially on songs with more bass. What can I try?

try to exchange your left and right speaker to confirm. where the cracking noise come? it could be from speaker or your amp itself. 1.if after exchange speaker, it still happen on same speaker then is your speaker already damage could be the cone edge or the coil.
2.If happen on same side from your amp, then that channel output is damage from amplifier.

Yamaha stereo only works on Pure Direct

It sounds to me like an audio enhancement filter is malfunctioning. The pure direct on / off is a sound filter to alter the sound performance of the receiver. There is a rare possibility that there is something wrong with one of your speakers- causing certain circuits in the receiver to malfunction. A way to check for this is to connect only one speaker and an audio source. test each channel first(without pure direct) by connecting the speaker to a channel and then disconnecting it, and connecting it to a different channel repetedly, until you have gone through all of the channels. If you really wanted to pinpoint such an anomaly, then you would need to do it with every speaker through all of the channels to make cetain that this is not the case. But then again this is not very likely. I would personally just use the mode that seems to work, because something is obviously malfunctioning, or possibly burned out. And repairing it is most likely costly! I hope that you can get something out of my answer! sorry! Good Luck!

Left side crackling noise Blown channel?

Would check your balance settings. Make sure your not balanced more to left than right. Next i would try to swap over one of the speakers from right side to left to see if it crackles. If not replace left side speakers.

Channel 2 crackles

Make sure your speaker wiring does not come close to the 12v power cable running for your amplifier. If your amplifier's 12v power cable runs on the drivers side of the vehicle, run your speaker cables on the passengers side and make sure your tweeters have a high pass filter to stop any pickup of engine sound (When you are driving you *WILL* notice it at high RPM. a HPF (High Pass Filter) will also stop those nasty hissing sounds on S's.

Noisy channel of receiver

Generally, crackling noises come from anyplace there is a mechancial connection for the sound signal. The volume control, main/remote speaker switch and possibly the headphone jack. That is where the contacts must be cleaned, but it requires dissassembly. Try operating the main/remote speaker switches, and plug/unplug a headphone several times. I am assuming there is still audio behind that crackling. Are you using both main and remote speakers simultaneously?

No output from left channel after crackling sound

Marantz SR 5200/6200 lost audio or crackling on left or right channel except in mode s-direct is now fixed !
The root cause is a defective inegrated circuit on DSP board (the one with digital inputs). To fix it change the chip CS4391 by a new one or better by the improved version CS4392. On my device a capacitor was cut close to this IC : replace one 1uF after changing the IC. For any question search me with my callsing "F5RCT"; i have a spare IC for the one who is able to change it !
I'm amateur radio and engineer
