Karaokecathy Posted March 22, 2015 Share Posted March 22, 2015 Hi I'm new to all this but I need some advice my master fader keeps cutting out first one side then some times the other. I'm not sure if they need changing if so how to go about doing it. Any advice is appropriated. Thanks Link to comment Share on other sites More sharing options...
Simon Lewis Posted March 23, 2015 Share Posted March 23, 2015 Hi, and welcome to the Blue Room! It could be that your faders simply need replacing (not too difficult if you can take equipment apart, solder, test and reassemble confidently and safely). However, unless it's definite that the fader is the issue, then it's probably worth getting someone to look at it and check that there isn't another problem causing the output to cut out.It's quite difficult to diagnose without seeing the desk in the flesh!

KevinE Posted March 23, 2015 Share Posted March 23, 2015 To change the master faders on a PM1000 you will need to seperate the mixer deck from the amp section by undoing the appropriate screws at the rear, front and top. Lift the deck up and disconnect the 3 cables taking care not to damage the IDC connectors. Seperate the jumper cables from the channel board.Ideally remove the FX board, take antistatic precautions. It unplugs. It's easily damaged and best stored seperately from the main pcb in an antistatic bag. Then you need to pull off all the knobs from the faders, pots and eq sliders attached to the master board. Keep them in colour-coded margerine tubs. Then you need to undo the nuts for the appropriate jack sockets across the top of the board, and any philips screws holding the line in/out sockets. There are several screws attaching the pcb and faders to the metal faceplate, you'll need a small hex driver for these.You can then seperate the master pcb from the deck plate. Give the plate a bit of wipe as cleaning this is easier with no pots poking through.Unsolder the worn fader potentiometers from the board and fit the new ones. The pcb is plated-through so it is easy to damage the tracks if excessive force or too-small an iron is used. Damaged tracks will be difficult to repair if you only find out after the desk is reassembled. Put the rest of the mixer together. Make sure none of the leds are bent and that they all align with the holes in the deck plate before going further. The ribbon cables only fit one way, dont force them or bend any of the pins. Some revisions have a dab of hotmelt glue on there to keep then in place. That sounds long-winded but there's no other way of doing it. :) As Simon has suggested, make sure you've diagnosed faulty faders and not simply seen symptoms of a different fault...otherwise you'll have wasted considerable time and effort changing good faders!

5catfish Posted March 27, 2015 Share Posted March 27, 2015 Hi Cathy..... not sure how old your desk is but just to mention Powermate desks come with a 5 year warranty. If within this time frame, take it your local Dynacord dealer and they can get it replaced Link to comment Share on other sites More sharing options...
