Dear Friends, I have this Audio system (tuner,twin

Question edited for clarity.

There is a small battery on the mainboard that makes it keep its memory. Yours has failed or become depleted.

when you're recording, what is the source ? CD ?

To record from the built-in FM-tuner, you can use either the DVR/BDR or the CD-R/TAPE outputs of the receiver.

Your question is posted under a "CD Shelf System" heading. If you really have one of these, the answer is "you can't". The CD player is a player only, not a recorder.

On the other hand, if what you're asking is how to transfer cassette tapes to CD using a computer, there are a couple of ways. One is to connect a cassette player (boom box, component system cassette deck, etc.) to the line-in jack of your computer's sound card. Download and install Audacity, which is free software for recording and editing sound. Then you can record the sound from your cassettes as you play them into the computer.

Another option, If you want to be fancy and spend a little money, is to buy a USB cassette deck. It automatically converts the cassette audio to digital and sends it to your computer over a USB cable. Recording software is supplied (sometimes the Audacity program mentioned before). Several companies make them. Here's one from a company called ION that some friends of mine have, and it seems to work well for them. They've been converting a lot of tapes of family members, and Audacity has been good for cleaning up tape hiss and enhancing the sound.

Either way, once you have the sound in your computer and processed to your liking, you just need to burn it to a CD using whatever burning software you have. (I use CDBurnerXP. It's free, easy to use, and does everything needed for normal CD and DVD burning.)

This should be because you have not used the player for many years. Does the system eject the CD tray? Use the CD head cleaner CD that removes dust on the laser head if any. Try using the audio CD which are recorded in .cda format and not ion MP3 format.

to use it with either decks or a mixer check to see if it has record out and play in ("REC OUT"/"PLAY IN") for tape 1 or tape 2 if so you can use a mixer connected there. If no tape inputs or record out you could only use the CD ("tuner" is a internal selection not an input selection) as play back connections.
Post back if you have more questions

The dvd recorder uses the video signal to detect, thus it will not detect the audio as a signal. I believe there are "boxes" you link in somehow to "fool" the dvd into thinking it's recieving a video signal, but I don't know where to get them.

Yes, it is a little tricky...

1) CD Changer (output) -> CD input on Amp

this is tricky... this will allow you to record to your tape deck, and control the sound via the EQ:
2) Tape Deck (tape out / recout) -> TAPE PLAYBACK on EQ
3) Tape RecOut on EQ -> Tape 1 Playback on Amp
4) Amp Tape 1 RecOut -> Tape Deck Playback / Input / RecIn
in essence, your creating a loop starting from the tape deck, going to the eq, then to the amp, then back to the tape deck to record.

Your EQ has another set of LINE IN and LINE OUT - use the second Tape 2 on the amp to create another loop. This will
allow you to control the EQ for any of the other sources.
5) LINE IN on EQ -> Tape 2 RecOut
6) Tape 2 Playback on Amp -> LINE OUT on EQ

5) Radio Tuner (output) -> Tuner input on Amp
6) DVD/VCR Combo Output -> AV/AUX on Amp

7) PC Computer... you don't have room for this. You can either use the PHONO input, and you'll have to purchase a Line Level Phono Converter
or, get a Y cable and split the signal and share with some other source.

Hope this helps.
