Combining audio (CD-ROM, Paula and optional soundcard)
« on: October 31, 2005, 04:41:52 PM »
Hi,

I was wondering what options are available for the Amiga 4000 on combining audio in one output. Ideally you want to have one output to your stereo that outputs all the audio your Amiga is making whatever the source; be it CD audio, Paula audio of maybe even a soundcard like Delfina or Concierto.

I read about some graphics cards (like Picasso IV) also can handle audio output.

Next to the audio ouput there are some pins on the motherboard to connect a CD-ROM drive to. The only problem is that there are only three pins and the cable has four plugs. So you have to bend the pins a bit.

If you have a sound card you would connect both the CD-ROM and Paula to the sound card. You have to create your own cable for connecting the external Paula connectors to the internal sound card, though.

Bye,
Thomas

I have a PIV and that can handle audio input as well. I was wondering if I would get a Delfina Flipper I can still use one connection to my stereo for all output.

IIRC, The picasso card will only let you output one source at a time.

The A4000 CD-Audio in is not vol controled so you get what you get.

Several years ago I made a prototype device that let you mix classic A-Audio with CD-Audio and had a vol. control on the CD-Audio.  Never posted the resistance setup but it is really easy to figure out if your at all technicly inclined.  If I can find the scims I'll post them.

The prototype was sold with My A2000 Tower...  :-o  What was I thinking...

Oh, another, EXPENSIVE, option is to get a Mediator PCI card and then buy a Sound Blaster that does multipule inputs.  I made a Headphone jack-to- CD-Rom Audio cable that goes from external Amiga audio to the sound card and the standard CD-Rom audio to the Sound card.  The software from Elbox lets you control each input seperatly...

PS- Abo. the A4000 CD-Audio in "bending" thing...  you can easily move the conectors in the audio cable head instead.  on one side of the head you'll see flaps that you can lift up with a pin, pull out the specific wire conector and then put it in the correct hole.  I don't know the pin out of the A4000 Mo Bo audio in so you'll have to dig that up somewhere else.

I don't really want to go the Mediator way. If I added a Concierto to the Picasso you can control the audio volume with the driver software?

But would adding a sound card make sense? What are the benefits? Would a Concierto make playing mp3 possible on an A4000?

Or do you need a different card for that? Like a Delfina?

Hi,

You could just use a simple Audio mixer?

If you are handy with a soldering iron there are a few designs on Aminet or you may be able to buy a small ready made mixer from a local electrical shop?

I have a soldering iron and could build a mixer I guess...

But I still have one question:

Does it make sense to add a sound card to the classic Amiga? What would benefit? As far as I can see only some applications benefit and there is no hardware mp3 playback with the zorro sound cards?
