4K,6K,8K Series / How does the SSL Pan-Law work?
« Last post by atticmike on Today at 04:07:04 PM »
Hello there,

Could someone explain to me the following things concerning the pan-law:

1. What's exactly changing the level? I guess if it is panned to the middle it looses level by a poti changing resistance and dropping the level and to the sides it increasingly gains the original voltage back that was going through the channel?

2. What happens if I send let's say a snare for example to a stereo parallel (via pressing for example 9 and 10 on the output routing matrix), which consists of two mono channels panned each left and right (subgroup engaged on the 2 channels 9 and 10) pan-law-wise? I assume the send is before is done before the pan law poti which means it lacks the effect of a pan law? Meaning for example that a drum mix on the parallel has louder mono tracks vs the drum mix going directly from the channels to the mixbus? Or is this send done after the pan law poti?
4K,6K,8K Series / Re: External monitoring not working
« Last post by oyanliz on Today at 01:31:56 PM »

I have checked each the component of the CF82E24 card wich can afect to the issue. I swapped TR11 with TR13 and checked all the resistors and diodes.

I spend some time checking the section and ST5 left input (from patchbay) is working routing via SLS monitor output , but no other external input is working. As far as I unterstund, CF82E28 cards are for SLS and Monitor selectors, but swapping them, nothing changes. I am going to check the connectios of the patchbay, but after this, I do not have more ideas for how to forward with the issue.

I would apreciate any help.

Thanks in advance.

Best regards.

4K,6K,8K Series / Re: 651 section slot 22 cap >SOLVED<
« Last post by oyanliz on October 19, 2017, 12:55:45 PM »

I do not know what is exactly this cap for. It is installed between 0V and a light brown wire on the socket of the CF82E21 card. I thought it was something standard in the 651 board but I am not able to find any info in the documentation (I do not have the original manual, I only have the manuals and schematics downloaded and bought on this forum).

Regarding to the problems on the monitor section:

- I found a TL074 op amp wit a broken leg on card CF82E24
- I found a 4023 IC plugged upside down on card CF82E22
- I will change the main monitor pot by one used but cleaned internally

Mini LS, Dim, Monitor cut... everything is working fine again. I hope the main monitor pot issue will be caused by dirt.

The external to monitor section still does not work. I am talking about it in another post of mine.

Thanks for helping!!



Thanks a lot for the reply.

I will definitely keep the producer's desk intact should I be able to remove it.

I just did it.
It's kinda easy. But a pain at the same time. You need the proper side panels to put it back on. So keep the producer desk in tact!

I have a SSL 4056 E/G with patch bays on the left and a producer's desk on the right. I would like to remove the producer's desk and reduce the frame to either 40 or 48 channels footprint.

Hi Matt,

Thanks a lot for your response.

The producer's desk is next to the bucket of channels 49-56 but it's not the one with the patch bay. The bucket with the patch bay is located on the opposite side.

If I decide the keep the 59-56 ch bucket, do I still need to cut any metal when removing the producer's desk?

Not sure if I understood the thread situation and how it is as I have never looked inside the metal work.

If anyone has any pictures so I can see what they should look like after cutting will be great.

Thanks a lot for the help.

Removing the producer desk is fairly straight forward. I am assuming your desk it laid put so that the last bucket is next to the producer desk?
if this is the case all you need to do is remove the BICC from under the 49-56 bay and cut them back on the patchbay, also remove all the VU meters (or plasmas) feeds.
Remove the 8 channels bucket and then shorten the metal work.
This is the tricky bit as the two metal bars that run along the console are threaded so you need to make sure that you either shorten those up and leave the thread on or cut them short and re do the thread.

This is not something that should be attempted, you would need a specialist in to show you how it's done. you really don't want to start messing with the metal work and possibly compromise the mechanical stability of the console.

My 2 cents.

Matt Sartori.

you have switching problems in your monitor path. Could be several things, but you need to get in and follow the signal (scope) thru the stages you have mentioned and see where it fails or changes in the wrong way.

The popping may be part of the problem (DC in the monitor path) or it could be just dirt in the pot, hard to tell from here.

to identify the function of the cap, you probably will need to identify the pins it connects to and on which card to "bring" it into the schematic. Ring it out. (that means use a DMM in resistance mode and set it for beep on short)

I just did it.

You are right, sorry about that.

- Monitor pot is doing more noise (pops) when moving (betwen rotary steps or positions)
- Mini switch is working all the time, lamp is on all the time (when main monitor is using, switching "Mini" on, signal is cutted on main monitor. But there is signal all the time on "Mini LS" outputs of the patchbay and the Mini switch light is on all the time)
- Dim pot and Mni LS pot seem that they sound lower

I am getting crazy with the external to monitor and monitor section in general. I have been able to put everything working except external monitoring selectors, but now everything is getting worse again.

I want to start checking everything again, but I do not know what this cap is for, so that is the reason why I am asking about it.

Thanks for replying, Matt.
