Question about Gem Sound DJ-2100 Turntable

Recording one channel only

I have a "GemSoubd Gem-USB" turntable. When I record, only the LEFT channel is being recorded. Nothing is being recorded on the right channel. The result is I am unable to record anything in stereo.

The unit is new. Is the problem a faulty stylus? What steps should I take in order to record both channels?

    Thanks guys, I appreciate the responses.

    My problem is I am not using RCA cables. The cable is a USB from the turntable directly to the computer. Radio Shack sells the cable for a ridiculously high price. When I posed the question about the cable, the salesperson at Radio Shack told me that the cable, in his opinion, was not the answer and advised me not to purchase a replacement.

    Any thoughts on this?

    Hi Freak1c,

    Unfortunately I am afraid you have the correct answer.

    As a aside, I have a number of LP's from the 50's that I am trying to put on an MP3. I have the BIAS SoundSoap software to remove the noise, but, with the turntable I presently have, I am unable to convert the LP's.

    Again, I really appreciate your input.

If you are using audacity, then you have to go into preferences and tell it to record in stereo by default....if not then I think it records mono by default. If you are recording on a stereo track and only the left is coming in (and you are using USB) then you might want to check the wiring on the cartridge. I am working on this unit for a friend and I can't get anything but static to come through.

I had the same problem on a turntable and it was the cable, those rca cables are notorious for breaking inside at the plug end. The stylus cartridge not being completely plugged in may cause it too I imagine. I'd bet it's the right rca cable broken inside at the plug end.

    You can get rca cables at radio shack or probably k-mart, etc.
    Get good quality beefy ones with gold plugs if you can, gold plugs are oxidation resistant, the better quality cables will have stronger plug ends than the original.
    The cable sets they sell for audio/ video connections are rca cables but they come with 3 cables, 2 for audio and one for video, you can just peel off one of them and use those if you want to.
    Take off the bottom of the turntable and you'll see where the cables connect inside the turntable, you may be able to just plug new ones in if there are rca jacks they are connected to in there, if not you'll have to cut em and splice the new ones on or solder new ones in.
    Of course this is all assuming the problem is the cable in the first place, but it's a place to start troubleshooting and cheap to do, and cables are always usual suspects.

    Bizarre, I didn't even know they were plugging turntables into computers via usb these days.
    If you are'nt getting signal on both channels at the input stage of whatever program you're plugging the turntable into the computer then the problems with the turntable, could replace the cartridge and see if that helps, if it's a quality cartridge and costs a bit of money and would be about the  same price as having the turntable looked at by a repair tech though, I would just have a tech look at it because if it's not the cartridge or the cable then it must be an internal problem in the turntable, probably the wiring because there really isn't much to a turntable on the inside.

Getting lidl silvercrest turntable / audacity to transfer records to computer

Assuming you've installed the Audacity software, first check your recording device. If you use Windows, first check the Audio Control Panel. For Windows 7, click Start > Control Panel > Hardware and Sound. Under Sound, click on the Manage Audio Devices link. In that window, click on the Recording tab. Select the USB option and make it the active device.

In Audacity, you may also need to make sure that this is the recording device that is active. That should be the third drop down from the left in the Device Toolbar. (If it isn't visible, click View > Toolbars and check it.) The Device Toolbar is right above the recording trace section in my version of Audacity.

Now click Record (the red circle) and start your turntable. Do you see a change in the trace? You should see a flat line for up to 10 seconds and then see this change to a set of high and low values.

If you don't get this, check if your USB ports are working. If you use a USB hub, try a direct connection. Check the device manager under Universal Serial Bus for a triangle with a red x or a yellow triangle. Try updating the driver by right clicking on the device. Also check Windows Update (for an optional update) or your computer manufacturer site for a new driver.

Unfortunately with the USB, you can't hear the recording as it is made. Do a short recording and then stop it. Then play back the selection. Adjust the input volume level lower if your trace is hitting the top of the box. This is clipping and your recording won't include the full signal from your record.

I've used Audacity for recording cassettes through the line in port. You can do this with some turntables if you add a pre-amplifier and use RCA to 3.5 mm adapter. Connect to the line in on the back of the desktop (blue).

If you could not install Audacity, go to to get a version that works on your computer's OS.

I hope this helps.

After recording lots of music from my Ion Contour LP I have suddenly lost output from one channel??

First disconect the wires to the cartridge. With you amp on, touch each wire one at a time. You should hear a buzz on two of the wires (one one each channel) and nothing on the other two. If you do hear the buzz on both channels the cartridge has failed or the connection to it is poor. If you are still missing a channel then the problem lies in either what connects the two devices, or the magnetic cartridge pre-amp inside the amp.

It sounds like you've connected it to the computer's MIC input instead of LINE IN input.
Check your sound card connectors. The icon for LINE IN will be an arrow pointing in to three curved lines. More-or-less like this:
