some dude said: "As a consultant on the road, I see a lot of mixers being taken out of the closets. There are only a few details you need to consider.

Some models of the Tascam line did use some plastics inside the mixer. Mainly behind the pots and for the back side of their connectors. If you feel comfortable to out the back of the mixer, look for light colored plastic covering for pots and fader controls. If you see any, DO NOT use any sprays or cleaners even if it says it is safe for plastics. Using any alcohol or oil or silicone based spray will make the plastic hard, brittle and you will shorten the life of that mixer.

If the plastic is dark gray or black, using a contact cleaner that is safe for plastic can be used.

The best thing to do is just start using it. Test each channel, see what is work and not working. Using chemical for cleaning is generally not a good idea except for the faders.

For the TRS or TR connectors, inserting a connector into each one about 10 times will push out of the way any rust or corrosion. Opening the mixer and trying to clean the contacts is not a good idea unless you’re a professional. You may disturb wires that are not meant to be moved and break the contacts.

For XLR connectors, again, inserting them 3 or 4 times is all you need to do as they have a larger surface area to make a good connection.

The worst case is having a channel or two not working. If that is the case and you can live with it, everything else should be working.

If you find that there is more not work and it is limiting you, then you are better off just getting a new mixer. Repairing any entry level mixer can cost more than a replacement.

Tascam makes good mixers. I still see many of them in churches."
