The Secret Society of Lathe Trolls

Hi there,

I just bought a grampian lathe. With this lathe comes a SC99 and VC200

What is the maximum cutting level with this cutting head and this poweramp.

I'll have certainly other few questions in this same topic later.

Thanks in advance to you Smile

Hello, can you post photos of your Grampian lathe ?
About your amplifier,you have a power of 68Wper channel.
The frequency response of cutterhead is of 20hz to 18khz with deep bass and clear sound.
Cheers.

I'd have to say, it's the loudest you cut before it blew..

This is a pretty pro setup and some cutting rooms use the sc-99 for mastering, you have a good setup..

my first test are really good. Level is very good too.

I got some other little problems there have to be solved.
For example, the space betwen grooves at the start of cutting is really too big.
I have too find a solution for that.
The speed of the plate at 33rpm is a little bit higher than normal should be.

I will post some pics next days. Maybe some of yours could help me.

ask to Andre http://www.vinylium.ch/

he is a good men and i believe dont have any problem for send you all documentation about

for lathe things...its a 60hz or 50 hz turntable motor? ask to your salesman for adjust

with good sound processing you can cut PRO levels

you're probably listening the sound with reverse riaa and this is the cause because your sound is more clear compared to the original input sound.

ok, so this fact remember me a system that was used in the cassette tape decks of 70-80 years that mounted 3 head built in permalloy material.
When I hear the sound just recorded a moment before, I can play a sound more clear than the input sound, this because permalloy load on the tape an extended dynamic.
I think that a similar thing can happen in your cutterhead, because the sc99 has the magnets of high quality.

Sorry, but that's impossible.
You can hear a sound that you like better that has altered frequency response or a type of distortion that adds color to the harmonics of the sound that you like but the recorded output of any device can't sound better than the input unless the input is for some reason being altered, in which case you are repairing a deficient sound. An example would be a source recording lacking bass which when put through a recording process that ends up boosting the bass the end result is "better" because one compensates for the other. As to dynamics, they get played with all the time through compressors etc. Almost all analog recording devices compress (and distort) sound when driven to and past their designated maximum recording levels on peaks. I never have heard of anything but an expander box giving increased dynamic range. Even then it is artificial - making up for compression somewhere else. Sometimes with things like Dolby if you turn it on when it was not recorded with it it can make the recording sound artificially expanded.
Although we do things with computers and boxes and recorders to make sounds we like better, we are not making them more like the original than the original. If it sounds good going into the microphone and everything else does not degrade or change the sound, you can only make it different in a way that sounds better to you. Not flatter than flat or lower distortion than none.
