GSSLSuperSidechain

[ilikeit]

hi,
i have a PCB and all the components for to build my FS. GSSL Side chain
this is the barclaycon's pcb
i have few questions about it

the connection 0v/snd/ext is for the external sidechain
so i must plug the jack 6,35 TRS? what is the place of each connection?

com/off/on/potA/potB are linked with the gssl pcb
like that?

i suppose it

the connection "in SW" is for the bypass of sidechain?
what is the good switch for this??

thanks for your help

Regards

nobody can help me??

These connections are for EXTERNAL.
Most people only use the Ext. connection and therefore only connect Ov. and Ext. to the jack socket (Sleeve & Tip).
The SND connection is for people who might want to send the sidechain signal out for processing before bringing it back in.

com/off/on/potA/potB are linked with the gssl pcb

Yes, exactly. This is for switching the compressor IN & OUT - though of course the audio signal still goes through the electronics.

the connection "in SW" is for the bypass of sidechain?
what is the good switch for this??

No, this is for the switch which operates the function described above.
Short the connections for the IN switch and it compresses. Leave it open and it doesn't. Any switch will do - SPST toggle is what I use.
When you short the IN switch it also illuminates an LED connected to 'IN Led'.

I hope this is clear.
Like I said, I made this board to match the functions of Purusha's GSSL front panel.
Maybe I will post some more pictures and instructions to the web link.

No , that is the connecting point for the gssls main bypass switch ...not a sidechain 'in/out' switch...I believe that is done on the rotary switch.

I haven't wired up this yet , but I talked to Martyn about it...

U can use any latching switch there , but as it is controlling a relay , and led supply is provided , why not go for an eao series 01 ..(1 n/c 1 n/o illuminated) !:wink:

They are available in the uk from "Scattergood and Johnson"

cheers

haha!...u just beat me to it, Martyn...

Good..it's better from the horses mouth!:grin:

Nay, nay, and thrice nay.
And yae I say, nay again!

Maybe I should post a few more pictures with some comments and suggested lineup etc.
Because the GSSL has been a project that's been around for a long time, it's easy to assume that everyone knows all of the various threads.
I've built about about 10 of these things so far and decided to design the PCB to tidy up all the loose ends and incorporate all the sidechain stuff.

Best regards.

I think that would be really cool!

There are probably gonna be questions relating to the use of the supersidechain in conjunction with the new turbo board also..

One thing I wanted to ask : When using the turbo board , we need to use two sidechain filter boards . However , we still only need one bypass relay....So is it as simple as just leaving that section of the supersidechain board unpopulated , on one of the boards?

Yes, absolutely.

Also, for people who are using bypass switching to completely switch out the electronics, you don't need to use the relay section.
Unless, of course, you want to have the facility to turn the compression off with the signal still going through the electronics.

hi

if i have understand the element for the "in switch" connection
is for a real bypass of gssl?or it keep the level of make up?

i must to use a simple SPST toggle for that?

i m sorry my English is very bad so i m asking a confirmation

regards

The 'In' switch is for Compression 'In' when it is closed, Compression 'Out' when it is open.
When the switch is open, the 'makeup' gain pot has no effect.

Does that answer your question Greg ?
Post again if you still need help.

I've posted a few more photo's and some notes on the weblink:

Hopefully this will clarify things.

There are two sections to the 'compression-enable' switch, one which disables the compression, the other which disables the make-up gain.

The signal always passes through the compete signal path, so it shouldn't be called a bypass.

Il y a deux sections de l''interrupteur "compression-enable". L'un qui arrete le fonction 'compression', et l'autre que arrete le fonction 'make-up'.

..see? My French is much worse than your English, so don't feel bad at all!

:wink:

[ilikeit]

ok
thanks for your explications!!

ssltec, your french isn t so bad!! :wink:

OK you asked for it...wiring in conjunction with TURBO board...I've got Purushas panel - where the GSSL switch goes I'd love to switch between SuperSC and Oxford modes with a (hard)bypass in the middle. This could be done with one board(SS/C) and an on/off/on 2P2T toggle sw?. Can the relay be made to hard bypass when disconnected (middle "off" position)- then connect to 47ks and turbo board in the down "on" position? Also with two more poles (4P2T) I want to use a 2 color LED (reverse the polarity - one on each extra pole) for positive identity and mini light show :green:  ....or is this just an embarrassing dream? :roll:

 

[ilikeit]

i m updating my gssl with the ssch pcb
but now my gssl don t compress
the signal go across the gssl because i have the sound in output
i must remove the 2 47Kohm ?
the make up is ok
the bypass is ok
my tensions are ok
all is wired
when i use a generator i can see the signal on L or R in input on tne SSC PCB but i have any signal on the "return" pin
Is it normal?
have you got some idea??
thanks

 

[ilikeit]

please!! :sad:
i hasn't signal on my return pin
just before this pin we have a resistor
before it i have my sine but after it nothing
i don't understand
a little help for me
nobody?

There are two sections to the 'compression-enable' switch, one which disables the compression, the other which disables the make-up gain.

Which one is the makeup bypass, Keith?

The 3 wire COM/ON/OFF or the 2 wire one?
