SOURCE: Low Volume on CDs - Roland 2400 CD
Hey Rick, There are a couple of places to look; I'll assume you have a decent input level near -12db average without peaking. First, ensure during playback upper right meter labled MST is near peak without going over, if you have room push the master level above 0db to +1 thru +6db and recheck for peaks above 0db. (You never want digital recordings to hit above peaks, you lose quality or resolution of the sound) As you find the sweet spot, master rec to 23/24-16 using the elevated level on the master fader. The manual suggest editing and mastering with the master fader at 0db however if you don't compress your tracks individually or reprint them at higher levels, you may have a great mix at an overall lower volume, pushing the master fader should help for a quick fix, but if this cures the level issue, try compressing and leveling each track to peaks prior to the first mix only lowering tracks which are too loud, when you get to mastering, all your signals are at their top potential for the CD. Spend a few minutes burning samples at low, just below peak, and just above peak levels on separate tracks and playback in your boombox for reference to a commercial CD. You'll find little to no difference when you are in the sweet spot. Another trick is to mixdown to a separate pair of tracks (not 23/24-16) and compress again during master mixdown rec. (ultimately 23/24-16) Good Luck Jeremy Yates, Radio World LLC.

Sounds like some solder / component connections have failed
Have a tech check solder joints on the power supply and output amp
I see this on a reg basis

One of the lines in the keyboard scanner has opened up. I have an idea what it might be and it is a nasty problem involving circuit traces that are silver conductive paint on a plastic insulating base that separate from a jumper at each end of the strip that the key contacts are made by conductive rubber pills pressed down by the keys. The contact of the flexible circuit under the keys to the jumper cable can be broken by vibration. I have an EPS7 with the problem and other than replacing the whole contact strip under the keys it really has no easy solution.You should probably have a Roland shop look at this problem. If your unit has this same arrangement it is repairable only by replacing the whole key contact strip.
Place your mixer in a location that will allow you to hear the sound coming from the speakers clearly. The best placement is opposite the speakers, centered between the left and right pair. Connect the power supply to your mixer.
Connect the female end of an XLR cable to a microphone. Run the other end of the cable to your mixing board. Plug the male end into the "Mic" port of an open channel. These channels provide the preamps that will shape the sound characteristics of the microphone signal, processing them for output. Repeat the process for each microphone in your rig
Connect one end of a balanced 1/4-inch cable to the left channel jack labeled "L" found on the "Main Out" panel. Connect another cable to the right channel jack with the "R" label. Connect the opposite end of each cable to the matching left and right inputs on you amplifier.
Power on your mixer and amplifier. Test each microphone connected to the mixer for output.
Adjust the volume of each microphone channel to create a balanced mix. Use the "EQ" knobs to shape the tone and cut out frequencies that are causing squeal and feedback.
