i have had a pm 80 for a while that originaly didn't work but i have managed to fix (well mostly need soem pot cleaner and poss a couple of new pots and faders) tbh i haven't had to do much, just clean a bit and resolder a wire here remove a randome bit of metal that was shortign the power supplie there any way i have now also got a crossfader for it but it is confusing me alot, it has a scerial port on the back as well as a 1/4 inch jack in a 1/4 inch jack out and a 3pin plug like a small xlr this is not like the one in the pic  as it has little number selectors either side of the crosfader my quenstion is... how do i plug it in? the 3 pin plug goes in the power suply on the aux power socet but where do the jacks go?? and what is the serial port for ??? it was mentioned on anouther thread that the crosover is conected with jacks to that
but the cross fader has no jacks, will this have somthing to do with the remote out? any help will be much appreciated thanks ps i willtry to put up pics later but i don't have a camera atm |

Just ring Formula Sound, they're still going
Just a thought, have you got the right versions of crossfader and chassis? The PM80 was re-issued recently and is internally different to the original ancient unit. ------------- Kevin North Staffordshire |

the serial port should have a break out to ? number of 3.5mm jacks they plug in to each input module BUT each in put mod will need to be fitted with a VCA and a 3.5mm socket Rich PS i had one once !!! |

Bringing this thread back from zombie land, does anyone have a schematic or circuit diagram for the main mixer section? I plug mine in and it is very very quiet, put it on pfl and it hard clips, but I got it off ebay for £30, so could well be only half of it in there. ------------- music is the message |

Gavin,make sure the main contact strip bus that connects all the modules together is clean,also clean the pfl function switches on all the modules. ------------- Be seeing you. |

I believe mine (the one in the photo above) was made around 1984,DJ Simon Harris bought it new from Formula sound,and used it on his early mixes,even Pete Tong and Froggy used this actual mixer too...Simon originally had it in his first studio. ------------- Be seeing you. |

JBL, I have always wanted to ask this question. Is Simon Harris on this forum the same Simon Harris who produced a track called: "Bass, How Low Do You Go?"? |

The very same! Simon also had a number 1 hit with The Real Thing- You to me are everything. ------------- Be seeing you. |

He is a legend. That is a classic track. The Lyrics are full of meaning and the instrumentation full of Soul! Still sounds great to this day. |

He was the producer on that track Pinyorouk,Simon has a gold disc on his wall for that one. ------------- Be seeing you. |

In the main power module on the top board there is an empty chip space, I presume for ME5534AN. Should this be occupied ? Can I use one out of a channel strip to see if there are any other faults? ------------- music is the message |

Burningbush, are you still interested in the schematics for the PM80? If so, PM me. I have few Formula Sound mixers myself, they are simply awesome mixers   |

I've just come across this thread by chance, I'm looking for shallow rack cases similar to those shown above for a PM80 mixer, I intend to make up a connector panel to go above the mixer in the rack so only top access is required, and ideally a removeable lid. Having great trouble finding a suitable case - can anyone suggest a UK supplier of something suitable? I must be searching using the wrong terms. Thanks! |

| There's a forum member here before offering custom cases if I remember correctly...im sure you could always try other companies if they can do you a one off according to your requirements.... but obviously this might cost you extra than the standard case. |

| hi Good evening to you i have seen your posts on the PM 80 and wonder do you have knowledge of the PM 90 i have one for years and has stood by me through thick and thin. but in the space of a few weeks i loaned it to a friend of mine and he used on a dodgy generator and took out all the regulators on the power supply, i have replaced them and all was ok , now a few weeks later an output channel has died and i have a hissing and popping sound on start up, . i have changed all the ics on the output card (pc 257) still no joy. i am running it in mono mode untill i get time to investigate more but i am hitting a wall , unfortunately i dont have a scope to trace so i am looking for any pointers you might have . |

Hi, I don't suppose your PM80 crossfader is for sale. I have been looking for one with the number selectors. Cheers, Chris.

| I know it was years ago, but did you manage to fix this? Could be a blown Op Amp in the master module. I have circuit diagrams and fixed quite a few if you need help. Cheers. |

| If the missing chip on the top board (that contains the display LEDs) was a 8 pin (DIP-8) IC, then it should be an NE5532AN. |

Hi, I don't suppose you still have the crossfader do you? Kind regards, Chris.
