GSSL HELP THREAD!!!

[mathflan]

Hi

I have already asked this question, don't know if it's the right place but I need some advice od Good sound engineers..

I like to use my SSL comp for mastering but I'am hesitate the place where I have to put the SSL ine the sidechain.

EQ PLUGS -> C4-.... -> SSL COMP

or

SSL COMP -> EQ -> C4....

What do you think about that??

thanks

 

[Purusha]

I would go with the second order :thumb:

...or maybe even the EQ in the beggining.

 

[mathflan]

I'll try that...

 

[Greg]

Generally, I'm a compression then EQ type of guy, but not always...

 

[mathflan]

I will try to use this sidechain:

EQs->Multiband compressor->SSL->limiter.

BUt I'am afraid to compress a lot...

I'am worried too, because I will have to Re-digitalize the signal for use my SSL.

As this is an error-fixing thread (and big enough already as is), it'll probably be better to discuss uses of the clone in the Brewery..

[mathflan]

yes, gyraf you 're right

:shock:

Hi all,
just a quick question...I'm changing my ssl bypass from original version to hardwire bypass with relays, but i'm not sure where (or how) to get 12v DC for bypass relay?
I tried several solutions but i'm getting hum...I made a relay board using a test board (i had that one at home and it was faster ot do it;i saw people doing it that way). I think RoogerFoote is not using extra regulators on his boards. I tried to use an extra rectifire using just one secondary and 12v regulator to take it down to 12v...Bypass worked always but i keep getting hum. There is no hum in bypassed mode... I'm missing here something. Just a wiring problem, ground loops?
thanks
well i think i got it...there is still some hum with make up gain all the way up

 

[suprughetto]

well, i fixed it; everything ok and working :grin:

Hello,

I'm debugging my SSL clone and I need some suggestions.
Here's what I have done so far:
When I put a 1KHz 1Vptp sine at the input, I measure a 1KHz 20Vptp square wave at the output. Moving the make-up gain pot, threshold pot, or bypass switch doesn't make a difference.
After several hours of IC swapping and measuring, I came to the conclusion the sidechain is causing the trouble. I discovered I could make a nice clean sine wave, instead of a square wave, appear at the output by removing the TLO74. I already tried replacing the TLO74, and I also measured the diodes, but it didn't solve the problem. Just to be sure I'm going to order some more TLO74's because I only had one spare left.
I don't know how this rectfier works exactly , so could anyone explain this to me. I'm especially interested to hear what the signal should look like on the different nodes of the rectifier.
I also welcome other suggestions.

Cheers!
R

Double check for shorts around the TL074... or incorrect resistor values.

 

[gyraf]

..and on the control board..

 

[OffChip]

Thanks for the tips. I'll check it out as soon as I find some spare lab time.

Cheers,

sorry to add to the length of this thread, i have all ready read it about 10 times through!!!

2 questions

1. i think my -15v rail is sorted to ground...It measures proper voltage but is reads shorted with the continuity checker on my dmm??
There are no soldering shorts and I have tried replacing most of the components associated with the rail...no change?

2. There is no ground path on part of the control pcb (relase and make-up as well as led and all of the .47u caps....etc) even when not connected to the main PCB? with power i measure 10.6v dc where it should lead to ground for example the LED negative terminal (oh yeah it lights up if i short it to ground??)
any thoughts... thanks in advance!

 

[Greg]

Regarding your first question... measure actual resistance. If something really low like 0.2ohm shows up, that's a dead short. I don't like the continuity beepers in general.

 

[dax]

thanks greg...
1. both rails read about 110kohms to chassis ground
2. there was a a broken pad between Control 0 and the off from bypass.

 

[rbaker]

So...I'm really sorry if this is really beginner of me, but I'm still trying to find the correct way to ground my ssl. I'm done with everything but this...I've seen a lot of discussion on how to do it---but nothing that ever said which was was the best. I understand I might need to make some changes (ie: trial and error) but how should I start? The ground connector on my iec has nothing connected to it at this point.

I'm a little afraid to plug it in...this is pretty new to me. :?

 

[Greg]

Ground on IEC goes directly to chassis !!! Safety !

Also ground from pin 1's on the input XLRs to the chassis.

Measure from the rails to ground to make sure there aren't any shorts.

Then fire her up ! :thumb:

I need help building the SSL clone. I just ordered the PCB's from Denmark and finished them minus the 3 2150 units I am ordering. I need to know where to buy wires, where to hook up wires, rack, PSU etc. Can anyone help a new DIYer?

Thanks,
Adam

Hi Adam,

Read through this thread - and through the SSL-clone threads referenced to by the "Meta-Meta" thread.

And read the page at Gyraf/diy.

And last, read the thread "META - Electronics 101 - By CJ"

That should do.
