20 Most Recent Gemini Sound Products Gemini Cdmp-6000 Audio Mixer Questions & Answers

I can give you some questions to verify possible problems:

1. Is the mixer, and ALL connected equipment powered from the SAME receptacle? If not, ground bounce can be causing damaging transients. This OFTEN requires running power back from where amps are to the mixer using an extension cord.

2. Are ALL audio interconnectsusing balanced lines where possible?

3. Is humidity 40% or greater? If not, possible static discharges from rugs, clothes, etc. may be causing transients that reset the unit.

4. Are stage lighting equipment run from a separate source to avoid transients from dimmers and switching?

5. Is the power all have three wire cords and the building have grounded receptacles?

If your system satisfies all these the next step I would suggest is a high quality power conditioner.

You MAY have contamination in the slider.You could try putting a little CRC226 into the slot and work the control. Use ONLY this product CRC226 available at Home Depot in the electrical dept/

The switch that the button actuates is probably broken. The unit will need to be serviced.

One of the first things a technician does with a voltmeter it to check 'all the voltages' in a system are correct..

Even without a specific circuit diagram for the board, 'Applications Notes' for chips and seminconductors will give nominal expected voltages in a working circuit.

Remember you can burn out the meter by connecting it to any source of current when on the Ampere or Ohm settings.
Technicians usially start at a high (highest) Voltage range setting and work downwards..

Providing the maximum Voltage is not exceeded on any range, whether it is AC or DC will not damage the meter.

'Fluke' by the way are a 'top end' professional product - check the price ;)

To skip the back story, start after first paragraph.
Tl;dr=take off the back, blow out the dust, check wire connections, make sure no rust or corrosion on components. Dry clean what you can. Reassemble. I have pictures if I can post them.
I had this same exact issue happen to my friends PKO-1000. I was offered it before she threw it out. I read the first page of forums that come from google on “Baldwin PKO-1000” I was ready for bulging capacitors, ripped wiring, or acid corrosion.

there’s a wide box of thin metal that hold all the computer boards and components soldered to them; making up the magical sounds of the machine. One end of the box has the wire connections. Behind that is the speaker and power wiring w/boards and the slow blow fuse. That is also where you will be shocked by the posts of the power chord if working properly.

If you know how to use a screw driver and handle 8-10mm hex screws, and have compressed air for dusting, it’s simple enough to take apart safely without complex reassembly. Dust it, make sure connections are clean and secure, and look for corrosion around computer components. That may be all you need at first.

So I got a used one of these for free because it had the same issue.
I read about battery failure, so I opened up the piano and sure enough the battery had corroded. I also read that the battery is only necessary for the memory feature, which I don’t care too much about. I pulled out the board (super easy to do, no screws or anything, it just pops out) and took it a local electronics/tv repair guy. In about a half hour he took off the battery, fixed a bad trace on the board with a quick solder, and handed it back. $40.
Plugged it back in, bam works like a charm.
As long as there wasn’t too much damage from corrosion, a repair guy should easily be able to do what I described.
I hope this solves your (and anyone else’s) problem!
