The UK built desks use different, higher quality, pots. Pretty sure they are ALPS, while the faders were either P&G or higher end ALPS.

Faders could have been Alps, but I'm fairly sure the ones I fixed used Sfernice P11 pots. Curious.

Hmm, I'll double check some spare strips tomorrow. I could be "mixing" brands.

I didn't read the complaint right. I thought it said there was no signal unless the control was turned up all the way. Long day and tired eyes.....sorry

Thats EXACTLY what I'm saying.

Everything else on the desk is perfect it's just the above, I have connected everything properly and all the volumes and other inputs work fine.

Thanks for all the replies guys, I will get the desk checked this week as I have been away for a while.


PS

I also have another desk Soundcraft Ghost 32 LE, one of the channels has a much lower output than all of the others, does anyone have any idea what the problem could be???

Does that desk have channel insert jacks? Maybe their shorting contacts need some cleaning. If there are flat wire cables (Connector board or mixing bus) involved you should also check these, as they tend to develop contact problems between the wires and connectors after some time. You can determine this by slightly pushing and pulling the cable near the connectors. This is a typical problem for these connections - they work for a while after after being kickstarted with higher levels. Many people who own first revision Mackie 1604 Mixers have to face this, but there are lots of other brands too. I saw Focusrite, Allen&Heath etc. gear where only exchange of the ribbon cables (or soldering the wire directly to the terminals) helped.
peace

Regarding the Ghost: Sounds like an input problem, maybe one transistor of the differential stage. What about the level in PFL mode?

Hi georgK

On the studio 24 I'll have to check it out properly, I haven't had a chance as of yet


I didn't check the Ghost in different modes (it's in storage), will get that check next time I hook it up too.


Thanks to everyone who has given their input on this matter so far.

OK,


I changed the input pots and a 10v 1000uf cap + 2 smaller 10v 100uf caps in the gain section (these are the only caps there) and Problem Solved

Thanks to everyone who gave me advice and much needed help with the Soundcraft Studio 24.

If anyone has a similar problem I hope that this thread helps.
