This sounds like a bad ground or short in a wire somewhere.

My Ibanez acoustic electric has very weak volume and makes a constant white noise hiss when plugged into an amp or sound system. Batteries are new as is the pre-amp and under saddle piezo. Ideas?


It will be either the saddle pickup or the guitar pre amp. If you unplug the pickup and the hiss is gone, there was your fault. Otherwise fit a known good pre amp.

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%.

I feel that the 'normal' background hiss is a problem that I would like to minimize with the sennheiser IEM 300. I'm currently using the IE 4 ear phones. Would a different/better earset with maybe a...


No, that will not help. The his is a function of the receiver NOT receiving a signal from the transmitter as they apparently do NOT have a "squelch" circuit to mute the receiver noise when no signal is being received. The noise level when no signal is received is pretty high and apparently the volume control is not enough to reduce the hiss.

To solve this, LEAVE the transmitter ON and make yourself a switch at the receiver. DO this using one of those little in line lamp switches that fit on zip cord. Make one on a short length of zip cor with mating connectors to fit the received jack and the headphone plug. Don't worry about unshielded wire as the impedance is very low. Then you use this switch to mute the headphones when you want to. There are other switch types you can use, I am just suggesting what might be readily available to you.

Sennheiser SHOULD have include a mute switch on their unit as turning the power off on the receiver would be a pain. They could have used a volume control with switch to kill the audio line out... simple solution... oversight on their part.

Technics sx-pr604 piano makes a constant loud hissing noise when on, everything else works fine. Is this hard to fix?


This could be many things. It is most likely noise from a defective chip in the unit. If sounds are normal except for the hiss, then test if the volume control reduces it. IF not, then problem is in the power amp section. If it does vary the loudness, then problem is likely between the D-A convertor and the volume control.

I would first try to isolate this by cooling selected parts with circuit cooler mist to see if you can find one that reduces the hiss when you cool it... Spray, then wait ten seconds before moving to the next on.

USUALLY semiconductors cause this, but rarely a bad resistor or cap can as well.

I recently hooked up my dtv box, tuned the antenna and have a great picture. On every channel I have background noise. Sounds like bacon frying, hissing noise. I also set up someone else's tv, very simple....


If there is a volume control on the remote that came with the converter box, use it to make sure the box volume is set to its maximum. Many models allow you to control the volume out from the box to the TV, and the levels are set about halfway. When you turn up the volume on the TV cause it's too low, you can get the kind of audio problem you describe. Make sure you turn the volume down on the TV first before starting with the box.

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.

Hissing


Sounds like you're connected to a cable, satellite, or DVR box ("set top box"). Many times these units have their own volume controls.

Try reducing the volume of the set top box to 80% or below, preferrably somewhere between 50% and 70%. When the volume is set too high, the background noise will be amplified as well, which then gets amplified by your receiver and becomes audible.

You will need to adjust the volume level of your receiver to compensate for the lower input level, and keep in mind that some channels may have more noise than others. It'll be a balance between having all your input sources are relatively-similar input levels (so you don't have to adjust the volume a lot when switching between sources) and how much noise you can hear or ignore.
