Clock port which can be used for faster Serial, parallel port/s or for a sound card and you can also buy a board which goes on the clock port so you can use 4 devices on the port. or below is what was really intended for the port,
(http://www.amiga-hardware.com/a1200clock.jpg)
A1200 clock port interfaces:
PortJnr - 460Kbps serial interface
PortPlus - 2x460Kbps serial & 800kB/s parallel i/f

The internal A1200 version
Four stereo inputs
One stereo output
Microphone pre-amplifier
Internal CD audio connector
Amiga audio passthrough
Sampling rate 8 - 64 kHz
DSP for A-Law/ยต-Law/ADPCM
Multi channel mixer
100% Prelude software-compatible
Full AHI support
Includes Samplitude CD version
Extensive customer support/hotline
This soundcard will plug into the A1200's realtime clock port along with a connection terminal in the rear expansion booth. It has almost all the features of the 'big' Prelude, e.g. true 44100 and 48000 Hz fullduplex, a multi channel mixer, record level adjustment, etc.
The Prelude1200 comes with a special connection terminal made to fit inside the A1200's rear expansion bay. The audio output as well as three inputs are available externally. A fifth internal connector can be used to route CD-ROM audio through Prelude's mixer. One of the external inputs will be directly connected to the output as long as the card is uninitialised. This is ideal for connecting the original Amiga output so that you don't need to replug any cables just to play old bootloading games which do not use the soundcard driver.
In case you want to build your Prelude 1200 into a tower converted A1200 there's a special customized slot bracket available which will carry the connector board.

You can use Prelude version designed for clockport I have one and it's pretty good. It has better sound than internal sound chip (Paula). It has passthrough for amiga audio, cdrom and additonal one can be used for recording.
To play mp3 you'll need accelerator.
See more at the manufacturer's site:
ACT Prelude homepage (http://act-net.com/Prelude/index.html)

Oook, that's a tough one, it used to be availble from main
Amiga-oriented distributors - that's how I got it, but quick
search didn't find any now. May be you should try to
contact the manufacturer.

There is also another clockport soundcard for A1200: Delfina 1200.
(http://www.amiga-society.de/ahwbook/delfina1200.jpg)
This card is no longer produced though.
Individual Computers (http://www.jschoenfeld.com/) is supposed to produce some new Delfinas (http://www.jschoenfeld.com/products/delfina_e.htm) though, and these should include A1200 clockport support via special cable.

Second hand Prelude cards appear on AmiBench (www.amibench.org) now
and then, so don't forget to check it out. That's how I got mine and
you'll be surprised how much you can save.
Cheers,
