At low volume it is fine after you get to about 20 on the volume it starts to crack,pop and distort very bad what is making this happen


Your speakers may say 350 watts but that is the peak wattage at which they blow up and not a wattage they can sound distortion free at. Look for the RMS wattage which is probably around 40 watts. If you look at the specs on your receiver you will see it will put out a maximum of about 50 watts but the distortion on the receiver is above 1 percent at anything over 22 watts. That means they are going to start distorting at around half volume. The other thing you might check for is a impedance mismatch between the speakers and the receiver. Is the receiver set up for an impedence output of 8 ohms but your speakers are 4 ohms impedance.

Transmit audio has a warble distortion


you will be better off taking this to a tech considering it is a ham radio also. he can set the freq and put it on a distortion meter also to find out the problem.

Receiver turns off at volume of about 45 to 50 when watching blu ray movies


It is picking up DISTORTION and is going in to shutdown mode.... (protecting your system) play it at 44 or less... not because it's BLEURAY that it's perfect, the level and quality varies from one recording to another... think of a cuttoff just like a car engine when someone tries to go over the dangerous level of RPM's... the engine cutt's off...

Why my wireless mic has distortion?


If it is the mic that is overloading, the audio meter on the front of the receiver will be going into the red. If this is the case, turn down the gain on the handheld transmitter. If the meter on the receiver is not going into the red, then the distortion is occurring after the microphone, probably in the mixer.

Tv picture is distorted


If the picture is the only thing distorted meaning audio sounds good and clear. It would be the connects between ur tv and reciever.

I want to know the power output, the watts


It has 100 wats/channel into 6 ohms theoretically.But it doubt it will drive the speakers simultaneusly at the rated power just like most of the receivers-not enough power in the power circuitry/transformer and cause distortion.I think it can handle 30-40 wats/ch without distortion.

How many total watts does this system have


Well... It consumes 240 watts of electrical power total so take the audio power specifications with a huge grain of salt, as no audio device puts out in audio power anywhere near what it consumes in electrical power. Heat produced is power consumed, too and nothing is 100% efficient.

In the specs below the only information useful for comparison is in the line I highlighted with >>> <<<<'s as it conforms the closest to the industry standard practice of using:

"X watts into 8 ohms (standard load) from 20 - 20000 hz plus or minus Y db at no more than .0Z% distortion"

The better amps specify vanishingly low distortion specs (0.0x% vs 0.x%) at the cost of being able to claim higher wattage. But they guarantee cleaner sound at the claimed levels.

JVC is being tricky with their choice of a 40 hz lower limit. THAT is the power hungry end of the spectrum. 20 hz is normally the lower limit stated.

"Output Power .............At Stereo operation
Front channels .............55 watts per channel, min. RMS, driven into 4 ohms at 1 kHz, with no more than 0.9 % total harmonic distortion. (IEC268-3/DIN) 30 watts per channel, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.9 % total harmonic distortion. (IEC268-3/DIN)

>>>>> 30 watts per channel, min. RMS, driven into 8 ohms, 40 Hz to 20 kHz, with no more than 0.8 % total harmonic distortion. <<<<<

At Surround operation
Front channels .............50 watts per channel, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.8 % total harmonic distortion.

Center channel .............50 watts, min. RMS, driven into 8 ohms at 1 kHz, with no more than 0.8 % total harmonic distortion.

Rear channel .................50 watts, min. RMS, driven into 8 ohms at 1kHz, with no more than 0.8 % total harmonic distortion."

I have distortion coming out of my front right channel of my AVR


Yes, sounds like your DSP chip has an issue. Not an inexpensive repair if that's the culpret. Around 400-500 to replace the chip. It's an awesome receiver and worth 300-400 in repair, however, a 3800 or 1800 can be had for 600-800 depending where you look. If you need more help, post a comment and I can help you some more.

Sound distortion on beomaster 3300


There is a defect in the pre-amp section of the unit. Without seeing it and taking a few measurements, I can't give you any particulars. A rough estimate for a repair wouldbe about $10-$25 in parts plus the local labor rate.
