CRT monitors in a recording studio

[Headbanger]

Hi.
I am playing my git/bass in front of
my PC, since I am artist and engineer
and everyone else in my little studio.
So a lot of noise from the (2) CRT
monitors gets on the recording.
I just can't afford TFTs at the time.
Is there a trick, does anyone know ?
Thank you.

* more distance from the monitor
* the noise is directional, tweak your mics and/or monitors to minimize the noise
* some mics are more susceptible to monitor noise (in my radio station studios the noise was magnetic, no electric, field noise)
* get a noise-reduction plugin
* get more $$$ and dump the CRTs. Remember, a 15" LCD is equivalent to a 17" CRT. LCDs are dropping in price

It's the pick-ups, not the mic.
The mic is silent, all good.
If I point the guitar straight at the
CRT, it's almost bearable.
You are right, I have to get more
$$$, and buy flats.
I have to buy wood first, though.
Winter is coming..

But isn't there a electric field in
the first place, and a magnetic one
at a right angle over it ?
The thing is shooting with electrons,
no ?

Thanx,

You get one field, you get the other field. Some things pick up E field, others H field.

Yes, you are getting electromagnetic radiation from your CRT's. And a 15" LCD is not equivilant to a 17" CRT. Different resolutions. I'll take a 17" CRT over a 15" LCD any day (with the exception of the EMR).

Just a few.

^^^ Having replaced a 17" CRT with a 15" LCD, I'll never go back. My ProTools system at the station uses two 17" very narrow bezel NEC LCDs - 2560 x 1024 resolution, 8 mS response, etc.

LCD monitors simply own. It's like Porsche - there is no substitute.

I just turn mine off while tracking and turn it back on when I need to see something on the screen. Most of the time I just jot down my location points like chorus,verse 1,ect...and then hit F5 on the keyboard, which is my GO TO shortcut, and type in the measure I want to start from. Hit enter, then record.

The electrons is a minor problem. The source is primarily the coils that divert these electrons to spread them over the screen. I bought my flat 15" when they were still in the upper five hundreds but never regreted even though I understand what Cory means.

BTW I didn't know there's still "West"Germany" ;)

Thank you, everyone.

Got to save some money.
Maybe I'll do the turn on/off-trick
until the CRTs give up.

Right, Hynek, there is no West-Germany.
If there was, I bet I could afford
the two flats.. ;-)

There is one good thing about it.
If I play my parts standing,
I rock more.

Thanks for the links, Champ.

Having worked in studio for more years than I ever intended I can recall the days when CRT was the only choice, and we just had to deal with the issues created... The easiest is to move away from the CRT... the other is to build a box around the CRT (leaving only the screen side open) that is lined with a radiation blocking material...

We usually just used 1/4" chicken wire (wire screening with a 1/4" square weave) Solder a gound wire to the screen mesh and earth ground it... This will stop about 80% of the magnetic and electrical field radiation from the CRT...

If you look at pictures of control rooms from the late, 80's and early 90's you will see plenty of CRT monitors in the control room, 90% of them boxed in the methods described above. Many of them were set into the soffit above and behind the console.
