Vinyl to MP3 Conversion...No Bass

Hello All… New to this forum and this is my first post.

I have an AudioTechnica LP60, I have it set to Mono, I am running through a preamp and I use RCA>aux to USB to hook this up to my computer. I can record in Audacity without problems and it sounds absolutely amazing through my powered speakers that are hooked up to my computer. I convert the files to MP3, using the highest setting which I know is not necessary. When I put the MP3 on my phone, it sounds great through headphones but when I hook my phone up to my Truck or my soundbar, there is almost no bass. The high end notes still sound amazing and if I touch my sub, I can feel it rumble a tad but there is almost no bass there. What am I doing wrong?? I have tried adjusting the bass effect which again, makes it have more bass in audacity and through headphones but there is still no bass in truck or on my soundbar. Any help I can get is greatly appreciated.

Note - I cannot use the Mic input on my computer and I have to use the Aux to USB… I am running Windows 10…I know very little about Audacity so please dumb things down for me. Thanks again everyone.

Puzzled looks all around. That’s an odd place for it to be dying.

There’s two. AT-LB60XBT and AT-LP60USB.

Why set it to mono? In Audacity do you get one wiggly blue timeline or two?

It’s not. “Low quality” MP3s have other problems, not sucky bass.

How? I can’t visualize that.

The phone may only have one speaker, so it effectively mixes to mono,
which can cause anti-phase (bass) signals to cancel out.

One of the channels may be inverted. The most likely way for that to happen is a mis-wired phono cartridge. It can also sometimes happen with a broken ground connection.

If one channels is inverted, that will cause the bass to be canceled when left & right are mixed acoustically or when mixed to mono electrically or digitally. (You’ll also get a “vocal removal” effect if the “center” is canceled electronically/digitally.)

Here’s how to check that -

  1. Record in stereo.

  2. There is a little drop-down arrow to the left of the waveforms/ Click that and select Split Stereo to Mono. That allows you to edit the left & right channels independently.

  3. Select/highlight one of the channels and then Effect → Invert.

  4. Click the little drop-down arrow for the top track and Make Stereo Track. (Skip this step if you want mono.)

  5. Export and check to see if the bass comes back.

Your turntable has a mono switch?

Is Audacity recording in true-mono (one waveform) or in “dual mono” (separate-identical left & right waveforms)?

That’s OK, the mic input is wrong anyway. You can use line-in on a regular soundcard as long as you have a phono preamp.

That caught my eye on the first read. Sound on a vinyl record doesn’t have any bass. It doesn’t fit, so the record burning system backs it down and it depends on the Phono Preamp to boost it back up. No bass is a very common complaint from someone who got their phono preamp wrong (or missing).

But that’s not your problem because yours is dying in the wrong place.

I’m with the mono-stereo cross crowd. Something happened at the playback step that only shows up later.

I recorded a short stereo voice track that is intentionally damaged. See what happens when you play it in your system. Choose the first one. LRMonoPhase4.wav
