The Secret Society of Lathe Trolls

Hi guys I have cut a silent groove.

I had no audio source from cuttersmp (off) and the sound was completely gone..

Souri said it's earth loop I'm going to hope the behringer box fixes it!

I'll be in touch

Just bought a Behringher HD400.. Ill let you all know how i GO..

Thanks Theo! Ill look into this!

Thanks all.. I am told by Souri that it is an earth/ground loop..

I will pull everything apart as suggested and start from scratch until I get to the source of the noise!

Appreciate everyones suggestions on here!

What is the purpose of that terrible little mixer other than to switch from pickup to cutting diamond?

The volume i adjust on the audio source anyway so I don't require the volume slider...

When you guys have done away with it., have you replaced it with anything or just bypassed altogether?

Mark that is fantastic and I will try each and every step you have mentioned!

You will hear back from me in a week!

OK.. Silent groove, cut a test cut.. Moved the groove speed controller dial, technics pick up - NO PITCH MOTOR SOUND..

So it is an audio signal, not mechanical from the motor.. .

What's next? Process of elimination..

Really appreciate everyones help here..

Thanks Mark - No I have not tried this yet and I thank you for this advice.

So I will remove the two leads that go into the cutter head - that isolates the audio input.

Brilliant! I'll try this in a minute and get back to you. .

Thanks for your replies folks. Surely I don't have to live with this sound?? It's more prominent when cutting, for example Acoustic music, at 45rpm where I change the groove speed during quiet moments to save on vinyl disc space. I just can't accept this as a thing to live with.. Any other VR users ...

OK.. So I had a very cluey mate come over and he plugged his oscilloscope into one of the leads that comes out of the groove speed control unit. The signal was smooth and not a PWM as we had originally thought. We tried several different things, like bypassing the Main units EQ, but still the groove...

ps: Cable routing? I have it standard as per Souri setup, i just replaced his ordinary RCA cords with gold plated ones. Wish the rig wasn't RCA's.

Thanks for the reply!

So when you say the 12v power supply - you mean the "Blue wave" box that Souri supplies as standard?

I'm presuming as the leads come out of that, it controls the voltage to the groove speed motor?

May I ask what you purchased to replace it please?

Hi ALL .. I am after some advice as I have tried everything to resolve this issue, and call upon your wisdom please! I'm getting a "whine" through my record cuts (obviously more prominent during quiet stages of the tracks) The whine noise is 100% from the Groove speed motor, so I have isolated it aw...

All good folks, disregard!

Hey all.. My order was messed up and now I dont have sufficient picture disc blanks to fulfil an important order. Does anyone have 20 x 12" pic disc blanks they could sell me? Happy to pay extra. Will need them asap please. Thanks in advance. oh.. must be able to cut on Vinylrecorder with VR Diamond...

Souri is great. We got along well during training session and he replies to all my emails within a day. My VR is fantastic and we have an awesome relationship. I have German grandparents who told me before I went over that is just the way they are over there - straight to the point and it may seem a...

Wow.. That's fantastic Thanks Snug Music!

Hi all. I really hope this has not been discussed previously as I did a good search on here for it and could not find a thing. I have the Vinyl Recorder and have created myself a "Groove speed" template (both 33 and 45 rpm) This is to tell me roughly what groove speed I should dial in for specific t...

Wow! I'm a little overwhelmed by the support from all you folks! Very much appreciated. I have some time tomorrow so I will perform a test cut and put up a video of my process onto youtube. I have been cutting since 2013 now, but this noise is really bothering me! I am cutting 33rpm no more than 0db...

I will certainly give that a try!

I have avoided stylus heating due to Souri making me nervous about applying it to the diamond.

I guess its time to start experimenting. .
