The Prisma Megamix is a music card for the Amiga computer.
It is dual interface, being both Zorro II and clockport so it can be installed in a big box Amiga with Zorro II/III slots or installed in an A1200 Tower with a clockport cable.
- Clockport and Zorro II interfaces
- Compatible with Amiga A1200 T, A2000, A3000, A4000, A4000T.
- Based on VS1063 chip
- Playback of wide range of formats: MP2, MP3, WMA, OGG, LC-AAC, HE-AAC, FLAC, ALAC, IMA ADPCM, G.711 u-law, G.711 a-law, G.722, and WAV PCM formats
- Pass through port for Paula mixing.

Before installation, it is important to observe anti-static precautions. Prisma is a [device] that can be damaged by static charge. Always wear an anti-static wrist band that is correctly earthed prior and during handling of the Prisma board.
Hardware installation into an Amiga with Zorro II/III slots
- Ensure the Amiga is powered down.
- Remove the computer casing to reveal the Zorro slots, carefully noting cable orientations and safely store case screws for reassembly later on.
- Identify an empty Zorro II/III slot. Ensure the contacts on the slots are clean and free of corrosion. If not, we recommend using a small anti-static brush with isopropyl alcohol (IPA) solution to clean the contacts.
- Handle the Prisma card on the edges taking care not to push or exert force on any component. Push the Prisma card in straight into the Zorro slot between the two rows of contacts. Ensure it is not installed at an angle and it is the correct orientation with the A-EON logo on the topside of the card. Installing the card upside down will destroy the device
- Connect the 16-way ribbon cable into the black socket on the Prisma board (it is keyed so it will only connect one way). Connect the other end to the Prisma audio back plate.
