    Hiss is independent of volume but more noticeable when sound is low or when the movie is quiet.

This is usually caused by a faulty electrolytic capacitor on the Output side of the audio amplifier.

How do I fix........Getting rid of background noise coming from my JVC KWV21BT?


You have described a grounding issue. This "hiss" is due to one or more speakers &/or the radio itself not grounded properly which is producing the "hiss". I would take it back to the installer and have him correct this problem. They have a responsibility to make sure it's working 100%.

My Fender Supersonic 60w head is getting zero sound thru my speaker. Not even the usual ground level hiss. Checked/replaced all tubes. The fuses are good. Cables are good.


Next is to check if the speaker is open circuit. Check with ohmeter or plug in a radio/hifi at low volume to the speaker.

If speaker is OK, next suspect is power supply. This will be over 400 volts so not safe for the unwary. I assume filaments are lighting up.

HOW DO YOU TURN DOWN THE HISSING NOISE


You can cut the treble gain some BUT most importantly is to send adequate signal to this speaker so volume level does not have to be set high when sending LINE LEVEL signals to it. Hissing noise is a product of the statistical noise that occurs in electronics. Running any device at high gain invariably brings up the hiss level. Managing thee signal levels is the responsibility of the sound engineer.

ALSO feed ALL interconnected equipment from the same receptacle or power source, even if it means running a power cable to a mixer alongside the snake. ALWAYS USE BALANCED audio cables whenever possible.

RADIO SHOWS STATIONS BUT NO SOUND FROM SPEAKERS


if no sound from both speakers check fuse,
if some hissing or humming on full volume then its a fault in oscilator section
if there is no hiss or hum at full volume its a breakage in the wires of speakers, if one speaker is ok its aagain a wire open problem in out put section
open up the speakers and just apply 1.5 volts dc for fraction of second to the speaker leads , if theres crackling the speaker is ok
also see for torn out cones or stuck cone or speaker coil open.

Microphone hissing sound


That sounds alot like the microphone booster in control panel. Depending on what version of windows your are using, you can just open the sound control from the taskbar and go to the advanced settings and uncheck the setting "microphone booster". Adjust microhpone volume accordingly.

Speakers have hissing noise coming out of them


Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.

Logitech x530 hissing noise


I had the same problem for the longest time with my set of Logitech 540 5.1 speakers. Turns out the solution was pretty simple. All I did was open the Master Volume controller and mute the Microphone. Hissing went to zero. Sound is great now.

Left Speaker Stopped Working


I think I had a similar problem. My speakers were brand new and after a while I lost my front left and rear left speaker. I'm not sure about you guys but after fiddling around with the settings it worked after I changed the "S/PDIFoutput sample rate" from 48 to 96 khz. I have no clue what I did, but it worked for me. I am running logitech something or rather speakers with VIA HD audio deck drivers

Buzzing sound thru speaker even with volume down to zero


maybe some filter capacitors of the amplifier has been drying out! check for the main filter capacitors and output capacitors of your amplifier. replace them if necessary with a higher capacitance but the same voltage rating!
