GSSL HELP THREAD!!!

On my trafo, it says:
Primary: 115V yellow/white 115V or-purple
Sec. I: 15V black-red 1,0 A
Sec. II: 15V or-blue 1,0 A

and on the website, it says:
Europa 230V Series Usage:
Orange & White together, Yellow to IEC 1 (L), Purple to IEC 2 (N or reverse)
USA 110V Parallel Usage:
White & Purple together to Mains IEC 1, Orange & Yellow together to Mains IEC 2

I have these colors bundled on my trafo (im guessing primary maybe?):
White · orange · yellow · purple

Then I have another bundle of wires on the trafo (Im guessing secondary maybe?):
black · red · orange · blue

on the back of the Voltage selector-switch, there are 6 pins:
2A · 2 · 2B
1A · 1 · 1B

On the back of the power ON/OFF switch, there are 8 pins.
4 of the pins are marked: E - W N - L (two of them are marked L)
The other 4 pins (on the opposite of on/off toggle switch) are not marked with anything.

This is as clear as I can describe it. Now, what do I do/wire/solder from here?

Got a Vol/Ohm meter? You can figure out your switch positions (off/on) & (125/250) by measuring continuity. Physically layout all your parts like the schematic to give you a visual aid as to where your solder points will be. Schematics are just like road maps.

These are connected when I test them for continuity.

When 230V selected: 2A and 2 are connected, 1A and 1 are connected.
When 115V selected: 2 and 2B are connected, 1 and 1B are connected.

So far so good, Jerry. I appreciate it.

There's an SC toggle-switch on the frontpanel, that connects to the pcb, at HPF*
(I guess it stands for SideChain & highpassfilter).

I just realized that my front-panel doesn't have this SC hole, because I've got a Turbo switch in its place instead.

Is it necessary to have this installed, or can I avoid installing this SC wiring on the pcb?
If so, do I need to make other changes as well?

I'm going to install a Turbo board once im done populating and at a later point install 2x SuperSideChain boards..
By leaving out the SC wiring/switch, will that affect these 3 boards on how to wire them?

 

[MiamiBoy]

Iv'e read somewhere that the HPF* slot on main pcb needs to be bridged if not used by SC wiring..?
Is this true? and if so, anything else that needs bridging or replacing ?

 

[MiamiBoy]

Control PCB - Rotary switches

These are not aligned A and B. I have no idea on how to connect them..?

Does A go to A or should B go to B? I have to choose because they can't both go to their designated place
very frustrating that there's no guide when buying this kit.

 

[JerryPbury]

There is a guide…..did you read all 440 pages?

 

[MiamiBoy]

Well yes of course
I do read every day. with the search words gssl...

but 90% of the pages are irrelevant to my questions.. soooo much to filter out!

Here' as a shorter read:

I've read it. I'm curious, how does that answer how to align my rotary switch to the pcb correctly?

I get that this is a DIY community where you have to do your own research and not expect anything being done for you.

I see people answer each others question all the time here, so why not mine?
I did research and obviously haven't found the answer here So I don't see a problem by me asking politely here and hoping that whomever knows the answer, sees my question, takes the time to answer it.

Do you know how to align these rotary switches, Script?

I remember having to figure this out when I built mine, but I don't remember what I did. It was just a little schematic reading combined with using my meter to test the switch a little, I think.

 

[MiamiBoy]

Yea, I guess most people didn't write down how they did things, haha..
which is very normal, but I was afraid of that!

EDIT: I solved it. The rotaries are now soldered correctly ! Thanks everyone

Does is affect rest of the board if HPF wire isn't soldered?

 

[gyraf]

yes, the wire link must be soldered in if no filter is used. otherwise you don't get sidechain signal.

 

[MiamiBoy]

Gotcha.. that makes sense! But doesn’t that make the SC permanent?

Or maybe I’ve misunderstood something.
I’m also gonna install the turbo board.

 

[Ricardus]

Why don't you want the sidechain option? It's SUPER useful.

 

[MiamiBoy]

might have misunderstood how the Mainboard works. I thought the sidechain part was the compression part.

I thought that the SC ON/OFF toggle Switch that is connected to mainboard (HPF*), is for optional highpass, (low-end roll off only) and therefor separate from sidechain, VCA, PSU etc.
And that it can be replaced by a 7step Super Sidechain knob if you choose to install the two boards?!
(60, 90, 130, 200Hz, TM, TL & OFF).

I don't have a filter board or sidechain board installed. I might install two SSC boards later, if Turbo isn't efficient.
Turbo is planned to be installed as soon as compressor is finished.

I see there's written SIDECHAIN sideways on the main pcb's lower right corner.
Do the SIDECHAIN and HPF*/SC toggle SWITCH have anything to do with each other?
Maybe they're the same but called different names at times?
Or are they 2 different & separate functionalities?
-
What I don't want, is the SC toggle Switch that came with my kit, connected to HPF* spot on the PCB,
because I don't have space for it on my frontpanel (they're reserved for Turbo and Bypass switches).
So if it's not critical or part of the original SSL circuit/function, I'd like to get rid of it.
I asked about it earlier in this thread

 

[Ricardus]

The device has a sidechain that when engaged the compression is triggered less by the low end, so you don't get pumping and breathing with a bass heavy mix (although some people like that pumping and breathing and use it as an effect). So with the sidechain off compression is triggered by the full bandwidth of the signal, and when engaged the triggering signal has some a HPF inserted so bass frequencies don't trigger the compression as heavily.

I think the super sidechain module allowed selectable frequencies for the knee of the HPF for the sidechain.

But no, the side chain is not an EQ filter put onto the whole mix.

 

[MiamiBoy]

Ok, I think I understand now. Didn't know the gssl had a built in sidechain when the original didn't.

I think the super sidechain module allowed selectable frequencies for the knee of the HPF for the sidechain.

Do you know which frequency it rolls off, circa?
EDIT: I have one 0,1µF leftover cap from my kit, so I guess roll off is at 130Hz/160Hz when using this.

But isn't the Turbo mode trying to solve the same problem?
If so, then the turbo board should be hooked up to HPF* on mainboard, instead of at the 47K & 100Ω resistors?
That seems logic to me.
