Loud bang from speakers

When I lift LP record off the TT, a very loud sound (60-100 Hz) comesout of speakers. So I always reduce the volume considerably to changethe record. The tonearm wire is properly grounded to the phono preampground terminal. I also tried to ground the chassis by connecting awire from tonearm base to ground receptacle of AC plug. All failed tosolve the problem. I think it is a static induced problem. The worst part is there is a very loud pop once in awhile during the play especially in winter. The humidity in the room is60 - 65%. I'd appreciate your suggestion.

I would suggest that you check the condition of the stylus, because the sound could be prouduced when the needle is lifted and the diamond tip is damaged so it makes a loud noise, normally a loud crack.

Music volume low when digitizing vinyls


The software itself should come with an sound imput level control. But if you can't find it or it's on full then there are ways round it. However it depends on how the turntable is connected to your computer. Most turntables require in an amp to have a magnetic cartridge pre-amp to boost the level to that say of a tape. Rather than mess around sometimes it's better to get one of these pre-amps and have that between the turntable and the computer. Then the sound should be the same level as a tape signal. You will have to bypass that pre-amp if you are recording anything else such as tapes to your computer. Or you will get a noisy loud signal!
Just search for a "magnetic cartridge pre-amp" on the web.

Califone 1815 k turntable. Loud hum from the speaker when powered on. sounds like a grounding issue. How do I ground the unit?


If it stays loud reguardless of volume it could mean the main Electrolytic Capacitor has failed in the power supply. This will be a big one around 4700UF in value.

Got record and it is not loud. never had any problems with other vinyl records sound quality. I want the songs to be converted to MP3 but the sound on them is so flat. other records I have converted sound...


Hi, maybe the record is worn and that's why the sound is low. By using third party audio editing software (i.e. cool edit [paid] or audacity [free]) you can improve quality and volume of digital sound.

Have a Sony PS-T2 direct drive TT. The tonearm drops in the middle of the LP rather than the lead-in groove and I can't get it to work right.


It sounds like it's been set up to play 7 inch records, check to see if there anything in the instructions on record size selection.

I suddenly heard alot of distortion when playing the Pioneer PL-990 turntable. Wonder if replacing the needle may take care of the problem.


Depends on the circumstances. Is it only when you play it loud? Air- or room-borne vibrations will feed back through the TT to the speakers. Keep the volume down to avoid it.

If you call the stylus a 'needle', replacing it maybe beyond your capabilities. There are lots of reasons for TT sound to be less than perfect and arbitrarily replacing things can do more harm or introduce new problems. Take it to someone experienced and equipped to evaluate the issue.

Tonearm balance, antiskating, dirty stylus, feedback.

I recently bought the below record player; http://www.robertopiecollection.com/Application/Products/steepletone/record-players-GB.asp thinking buying a brand new player would mean having no problems with...


Sounds like a bad ground loop or open shield to the signal path, or feedback from its own speaker or motor. The output of the stylus is so tiny that any electromagnetic noise can easily loom large if it leaks into the signal path.

Be advised that turntables and speakers should never coexist on the same platform or speaker vibration will feed back into the stylus, get amplified again and eventually overdrive the electronics and maybe blow the speaker, which begs the question - how did they get away with it back then? One answer is that there was never any real bass from one of these things.

Try it with minimum volume and work your way up. With the tonearm lifted and the platter turning, listen for audible hum coming from the mechanism itself. If you can hear it, so will the stylus when it's on the platter.

Got a pl990 turnrtable alot of distortion and terrible sound


Describe the circumstances. Only when played loud or always? What's the proximity of the TT to your speakers. It is NOT immune to airborne sound vibrations.

Ion ittusb turntable interference


Please describe the conditions under which the noise happens. Is it always the same place? Whic is it - static or some other kind of interference? Read the following. If you're using high speaker volume to monitor while recording you could experiment with identifying it as the casue by cranking it up to see if you can make it worse.

As with any turntable the following advice for this one will apply:

The tonearm setup is critical for proper tracking. Do it again with extreme care if mistracking is your problem.

I found one model online and a review with some sample of music. Quite interesting...

http://www.everythingusb.com/ion_ttusb10_usb_turntable_13231.html

The author complained about some things that clearly mark him as a stranger to finer turntables. Complaining about having to assemble and position the 'rubber band', aka the drivebelt, and the tonearm counterweight shows that he underestimates the precision required for a mechanism to rotate at a constant precise speed while properly tracking the microscopic undulations of the groove without skipping into the air or gouging it to death.

Some basics when recording from a turntable...
1) Place the turntable as far from speakers as possible on a solid surface that you will not touch during the recording
2) Keep the volume low enough that airborne sounds don't cause mistracking of the stylus *
3) Avoid anything that will cause vibration or movement of the turntable. (Tip toe)
* If you have a subwoofer, turn it off.

Some advice after reading the article: don't try to save recording time by playing the discs at 45rpm. The best tracking of the disc and recording of the minute details in the grooves will be at the nativespeed of the recording. Digital manipulation later only gloms up the accuracy you probably want.

In general, the fewer the conversions steps in the analog domain, the better; and the fewer the bit rate conversions in the digital domain, the better.

Have a B&O RX-2 with mcc4 and loud hum


Possibly check the wires on the cartridge, make sure none of them are touching and are not bent to badly, are all the connections tight? some cartridges require plastic sleeves over the connections, this insure they don't touch and
avoids resistances between them. Also some cartridges are not compatible with certain model turn tables.Is it universal? Also you my need a mixer most turntables don't work with amps alone. Mine don't. Usually most models you attach the ground wire to the mixer. A mixer boosts table power and take stress off the amp. Hope this helped! good luck!
