The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Great price, Quick delivery, the document was very usefull A+++++++++++++++

Setting the Correct Gain Structure
l. The gain structure is now correctly set�you�ve optimized the level of all signals coming into and out of the MIXPAD, and the end result will be minimum noise and distortion and maximum clean sound. You�ll now find that the majority of your mixes can be accomplished with most channel Level controls at or near their 2 o�clock �0� (unity gain) position and that the main Left/Right peak LEDs rarely if ever light (remember, if they do light, it means that something is distorting!). If you need to make adjustments to the overall level, alter the level control of your power amplifier.
If you encounter difficulty with any aspect of setting up or using your MIXPAD, you can call Samson Technical Support (1-800-372-6766) between 9 AM and 5 PM EST.
