Sound drops on the right channel after about 20 minutes to 1 hour of use. If I switch the Tascam X9 mixer off and on again both channels work again, but only for another 20 minutes to 1 hour. Could th
Problem with Tascam x9 - sound not playing from both channels. Connected speakers are Alesis MK2 Active monitors connected with XLR cables from the mixers main master output. When ever the sound drops from one channel, (always the right) switching the mixer off and on again always resolves the problem but only for a short space of time therefore only a very temporary solution. I have come to the conclusion that the problem must be something to do with the mixer its self rather than the speakers or the source of the sound. For reference the source of the sound is a computer with an M-Audio 2496 sound card connected with a high quality phono cable into the Line input on the X9.

Have you changed the speakers to see if it is a driver, or amplifier, issue? If it follows the speaker, get it reconed. If it follows the channel, look into that channel.
Try taking direct feeds from your 8 mic channels by connecting leads from the insert jacks to the inputs of the recorder. In order to not interrupt the signal path on the mixer channel push the jack all the way in and then pull out gently until you feel it click. Then you should get a direct signal going to the Tascam and still have control over the level via the fader.
Sorry but it does sound as though the power supply has an issue then and would suggest someone with experience electronics etc. Most guys with audio electronic should be able to assist,
If your mics are XLR (a hole on the bottom of the mic with three pins visible in it) you will need one of these for each mic, plugged into one of the four channels on the tascam that has an XLR connection (which will be the female version of the connection on the bottom of your mic). If your mics have a 1/4-inch connection, you can use the 1/4-inch connection on any channel on the tascam. For the stereo connection, you will need one of these of sufficient length to convert the RCA output from your stereo to the 1/4-inch input on your Tascam. Find "Tape Out" or "AUX Out" on your stereo and plug in the RCA side of the cable there (note which color you use for R and L). Use the 1/4" end of the cable to connect to two available channels on your mixer. Use the Pan knob to pan the left channel to the left and the right channel to the right, and voila! Hope this helps, and good luck!
Since nothing else is working, the cooling fan is probably powered by AC at line voltage.
The power supply that feeds the electronics has failed but it may not be catastrophic; it might just be an internal fuse that has given up from metal fatigue.
Each time current flows when powered up, the delicate element expands and then contracts when the power is turned off.
Some fuses have a zig-zag crimp in the element that helps delay the eventual death.
With the unit unplugged, remove whatever screws you find on the back or bottom of the mixer so you can peer inside.
If you are lucky, you may find the fuse in a clip or otherwise plugged in.
There will definitely be one in the incoming AC line although if the fan is running, this one may be OK.
There could be one (or more) fuses on the DC side that directly services the circuitry.
Fuses come in a variety of cases; they can be cylindrical of glass or ceramic bodies with metal caps on the ends and of varying lengths.
Others may be vertically mounted smaller cylinders plugged into or soldered (bad) to the board.
Some are nearly indistinguishable in size and mounting from several other types of parts; these though, will not have other than simple text on the part while the others will have more complex markings.
If you find and replace fuses, buy two so that an eventual tech doesn't have to grub around to find one.
If you replace any fuses and they fail again, DON'T proceed. You may damage the unit further and not help anything.
At that point, you need to turn it over to a tech.
One of the strangest things that has happened to both the consumer and the technical field has been the use of a flexible adhesive on many of these machines' circuit boards. The glue in question is vanilla-colored, and has a tendency to react to electricity by inducing capacitance, resistance, and in some cases, even causing inductance issues. The fix, of course, is to remove as much of this material as possible, and following right behind with a nylon-based retainer. Then, if the problem persists, a followup with tried and true technical procedures...accordianman
