MP3 Server - Sound Distortion
Sound Distortion

New MessageMP3 Server - Sound Distortion (modified 0 times) Loughr
I have a question that I wonder if someone can answer, I have the WebSurfer all setup and running Windows 98 on a 3.5" drive with the correct Audio and Video Drivers. I have the system hooked up to my 27" TV and Home Stereo (Phono RCA Jacks). when I turn the system on I get a continous humming sound coming out of the Stereo speakers. The sytem is incredibly loud, I have to keep the volume down around 1 otherwise the thing is just to loud (if that is possible). the Websurfer is currently sitting ontop of my Stereo receiver, has anyone else expereinced this type of problem with the humming, I am going to move the WS off the Receiver when i get home today in the event 1 of the 2 electronic devices is emitting a small electronic field causing this sound. Any other suggestions??????

Well, if the thing happens to be WAY loud, you should probably turn down the wav volume in the mixer. It's probably too high. The receiver is expecting line level input which it then amplifies.

well I went home and moved the WS off the top of the receiver and that didnt help. I then decided to move the RCA jacks on the back of the receiver to a differnt device, I chose a Tape device this time (Tape1). For some reason this worked, it appears that the phono jack is amplified and this was the reason for the exteremly high volume and Hum, there is a very low hum now, but not noticible when playing MP3's.....

if it sounds like a 60Hz Hum (probably) you may have a ground loop problem between the unit and the receiver. check your connections, perhaps switch out the cable that you're using.

If you're plugging it into a Dolby Digital/DTS receiver (with digital inputs) you can get yourself a seperate sound card that has Digital SP/DIF outputs on it. OEM versions of the Vortex 2 chipset can be had for about $49.00- most have coax output but some have the optical TOSLINK output on them. Way cool! The extra benefit is that you're using the high quality D/A converter in the receiver instead of the cheezy & noisy one in the computer.

NEVER EVER put anything other than a phonograph (a record player, those funny black disks that are about 12 inches wide) into a phono input. these inputs have a preamplifier and will distort anything.

Here's a simple lesson on audio equipment.

Ground loops are evil, any good audiophile will run a ground wire from device to device.

Phono is for Phonograph... if you dont know what it is dont plug it in there.

Computer equipment is NOT high end audio equipment.. you need audio equipment to make it work right.

Isolation transformer patch cords are your friend... buy one at radio-shack NOW.

turn on your cdplayer, play something and then switch back and forth balancing the audio out of your
player to MATCH that of your cdplayer. setting it higher than the other components doenst make it louder it makes it sound crappier.

If you have an equalizer remember... it's an EQ not an AMPLIFIER. in other words dont make it louder with the EQ, be sure to remove some sound level from other places so that what you add is taken away elsewhere (NOTE: Low end consumer stuff does this for you now. Protects the consumer from themselves.. Any EQ that cost less than $400.00 is low end)

When you thinks something sounds bad, assume that you messed it up, and check the settings again. 99.9% of the time the user has screwed a setting up so badly (By cranking all levels up to max) that distortion is present in large quantities.
