FatFrog generic/preset problem

[Webbo]

Recently picked up a 2004 FatFrog to play with, it has various problems. I've sorted most of them and upgraded the firmware to 10.12.1 but have an issue with the channel faders, they only reach 94% output.  The encoders & masters all reach 100%. Subs also at 100% when  using a file loaded from another Frog desk. Memory battery has been replaced, DIP switches are set correctly. The pre-set control switch might be connected with this as when in  B-faders / A-stored  mode, the output levels only run to 26%

Anyone got any ideas on where to look?

This is usually an issue with the channel faders reference voltage, or maybe the DIP switches on the channel boards if you've been rummaging around inside. I'm sure there are some posts on here or on the BlueRoom. I'll have a dig around...

Give Keith a ring at Zero88, he'll have you sorted in a jiffy...

(Mods: This post could do with being moved to the Frog Range MkI forum).

Apologies, just rushed it in whilst having a coffee☺

Hi Webbo,

Have you put the console into Test Mode, to test each of the channel faders? You can do this by booting the console with F1 held down. 

If you have any queries just drop us an email to support@zero88.com.

Thanks, 

Not tried that but will give it a go tonight.

OK. When in Test Mode, Channel flash buttons 1 through to 14 select sets of faders and pots to test.

Flash 1-8 = Channel Faders

Flash 9-10 = Submasters

Flash 11 = other pots

Flash 13 = Wheels

Flash 14 = Buttons.

You can check the level reported by the fader on the internal LCD.

Any queries just let me know.

A very useful facility

Looks like sliders; A-23 (0-FD), A-Master (stuck at EF) & B-Master (C3-FA) need replacing.

Thanks for the advice, a little job for next week I think, hopefully this will sort the issue.

Cheers guys, much appreciated.

Sliders replaced, desk now running at 100% output - result! Small problem still with B - Pre-set / A - Stored switch position, (not essential at the moment). Possibly due to a damaged SN74HC373N IC adjacent to the DIL connection socket, looks like the EM6788 33 3 main board has suffered some "liquid" spillage at some point, but will get round to replacing that with a socket & new IC at a later date, everything else now seems to be running.

Thanks for your advice & help.

Out of interest, does anyone know if this board can be obtained as a spare part, or know of a decent S/H unit wanting a loving home?

Hi Keith,

Glad to hear the desk is now running at 100%.

For advice on obtaining spares, feel free to drop us an email to support@zero88.com, and we'll be able to point you in the right direction.

All the best,

Edward

I have some Frog fader boards around as reclaimed spares - they're largely untested having been removed from desks that were put away in to "store" as desk upgrades happened, however the most that will be wrong might be failed/dirty faders. If you're looking for a board to replace one with damaged tracks or chips - they would certainly do the job.

If you want to pursue this - drop me an eMail to ian@serviceguy.co.uk.
