Prisma Megamix:

Multi format DSP music card for your classic Amiga

AmiWest 2013 18th October 2013

In its prime, the sound quality delivered by the Amiga's on-board Paula chip was pretty special. Its 4 channel stereo 8-bit audio output with frequencies up to 28 kHz when using 15 kHz screen modes, or up to 56 kHz with higher horizontal frequency screen modes was so far in advance of the IBM PC's monotone beep, which was virtually mute by comparison. The Amiga's audio was further augmented by a whole host of digital sound cards and samplers supplied by numerous hardware manufacturers. Sadly those days are long gone. However, that is all about to change. A-EON Technology is proud to announce Prisma Megamix, a modern next- generation soundcard for Classic Amiga computers. The Prisma Megamix is a dual-use card which can be connected to either the Zorro II or a Clockport and incor- porates a VS1063 DSP chip which can play and encode MP2, MP3, WMA, OGG, LC-AAC, HE-AAC, FLAC, IMA, WAV PCM and many other sound formats making it ideal for hi-fi audio playback and stream- ing applications. It achieves this with very little CPU overhead enabling full 200Kbps stereo playback on a standard 68K Zorro II Amiga while still allowing good multitasking. With Prisma Megamix, an Amiga 2000, 3000, 4000 or A1200 can mix MP3 streams and encode/decode them in real time without burdening the CPU. The MP3 sound processor is fully handled by CPLD and is transparent to the software. Audio data transfers are streamed at 16-bit (Zorro II) or 8-bit (Clockport), and bit banging is not required for SPI accesses to the MP3 sound processor. Mixing inputs for Paula, genuine sound and line in are provided, as well as earphone outputs and line outs. In Zorro II equipped Amigas, the Prisma's Clockport can be used for add-ons and multiple cards can also be installed allowing audio enthusiasts.

Prisma Megamix prototype to mix their tracks at full quality. Special drivers are being written for AmigaOS 3.x and 4.x systems and a Xorro PCI-E version is also planned for A-EON Technology's Next-Generation AmigaONE systems. Prisma Megamix installed in A4000.

@NovaCoder

Please contact me separately about development opportunities.  Ian is currently developing the prisma.library and we would value your feedback at this stage of development.

[amigakit]

Hi,

Prisma Megamix sound card has been modified, due to customer feedback to have an optional SPDIF expansion module.

Here is picture of latest prototype with the new SPDIF module plugged onto top of card:

[amigakit]

The chip on board does FLAC too

Here's the information on the sound card:

Spirantho has already got the Prisma card playing OGG files on his Amiga 2000.   Perhaps we can do some FLAC tests?

[amigakit]

@amigakit

Looks like a great sound card, I hope you sell a ton of them.

Thanks, we are working to get good software support for this product to make it really useful.  Hope to get direct support in things such as SCUMMVM and AmigaAmp - maybe FFMPEG would be a good candidate program.

[amigakit]

Wow!  That its really amazing that a 68000 can handle the FLAC file with Prisma decoding.

Latest News updated on Prisma Megamix:

Prisma.library is completed

MHI development is also completed and working- this is good for compatibility with programs such as AmigaAmp.

A new redesign of the board and SPDIF out option has been added and tested!

We are going to production shortly with first batch being a few hundred units.

Price is of course subject to change, but to give you an idea, it is likely to be approximately GBP £70 / 85 EUR including VAT (US $ 95 ) depending on final price of the sound chip and costs of hiring the production machines.  

5 EUR more was added to cost for gold plating on the Zorro connector - we thought this would be better than going for budget options.

[amigakit]

I will have to consult with spirantho who is currently looking into the driver's possibilities.

[amigakit]

The hardware passes through Paula sounds with a RCA connector where you can route the Paula sounds in and Prisma will hardware mix it.

[amigakit]

We will be producing the various audio panels for A1200 desktop/towers and big box Amigas.

[amigakit]

Nice video, thanks!

Just a note- the music pause in SysInfo is not a bug, it is simply SysInfo disabling multitasking whilst it calculates MIPs.

[amigakit]

@akiko

Duly noted- I will make some inquiries.  I have a Spider USB in my A1200 at the moment, so I take you point.  Also remember that the Prisma will work in a Zorro slot if you have a big box Amiga.

@novacoder

Awesome news: cant wait to view your video and try your port  Thanks for integrating Prisma with your port.

@spirantho
Thank you for your hard work on the prisma.library - much appreciated
