MC-02 Frequency Response and Noise Profile

MC-02 Frequency Response and Noise Profile

We've had a few people ask for more audio examples from our MC-02 lathes, specifically to hear the noise profile and to listen to cuts made by someone other than ourselves. So, we've produced some public examples showcasing both the sound and the frequency response of the cutterhead using pink noise for full transparency. This way you have audio to hear, and stats to look at.

Users of lathes with inline motors where the feedscrew is mounted with the motor in the lathe overhead will be familiar with the common issue of motor noise during lead in grooves or track markers. This happens because the feedscrew is directly mounted to the motor, making such noise difficult to avoid and is an issue we get asked about a lot.

With the MC-02, we use a stepper motor and have gone to great lengths to decouple it mechanically where possible. As demonstrated in our audio samples, lead in grooves and track markers are silent. While the lead out groove has some low level noise, the full cut includes a needle drop, a 0 VU pink noise cut, and a clear representation of the noise floor for context.

Below is our pink noise profile and noise floor example cut by us, an image of the frequency spectrum of the pink noise cut, along with further details for this specific cut and what happens and when.

- Stylus Lowered
- Then a 3 second LEAD IN groove
- At 4 seconds the PINK NOISE cut starts (with frequency mapped head EQ)
- At 20 seconds is a TRACK MARKER
- At 24 seconds the LEAD OUT groove

Alongside our music example cut by us some time ago, we have now added a test cut made by a MC-02 user who is not a mastering engineer like us and is simply learning the machine to our folder. They created their own frequency mapping for the cutterhead, and we had no involvement in the audio or cutting process.

Hopefully this helps with some of your questions.
