I'm not clear what you mean but perhaps this may assist.
By 'amplifier', do you mean an audio amplifier?
If so, although a stand alone DVD/CD recorder will replay CDs, I don't know of one which will /record/ to CD.
However, a suggestion is to connect the (audio only?) output of the amplifier to a DVD recorder - there will most likely be audio IN sockets on the front panel, maybe under a flap - and record either to hard disc or, alternatively, direct to /DVD/ (i.e. not CD).
The restriction is that, if you record to DVD, you'd need to replay the disc on a DVD player; it won't run on a CD player.
HTH, but apologies if I've misunderstood.
