New Amiga motherboards from Jens

I get what you want to do, you want to have a HEAPHONE plug and that's a different thing. You need a line amp plus a volume control knob, because otherwise it would always be set at TOO DAMN LOUD and damage your ears.

Yes, it'd be perfect to have at demoparties. But only if it's a headphone amp with volume control. If you have gone as far as adding an amp and volume control, you can have a knob that controls how much stereo separation you want.

Connecting your headphones to line output isn't a good idea.

Yeah, I don't see how mixed stereo is beneficial for musicians, I would rather have the option of dedicated output for each channel - quadrophonia I have a cheap mixer that I use with my computers, and for amiga I use two mono channels, and mix them left and right as I wish. Any musician has mixers much better than mine.

Well... i had impression that A-Clone/Clone-A is ECS implementation and AGA can be added as not big issue (natural extension for ECS features). Side to this other product (Indivision ECS/AGA FF) seem to show that this is working solution...
This made all so weird...

PANORAMA in software - this is obvious - you can control position of source within music editor not externally.

[kolla]

Yeah, well, but I would rather do that on something else than the Amiga.

Agreed, is exactly what I meant. Us musicians tend to prefer separated outputs for many reasons. Not only you can control stereo separation with an outboard mixer, you can also effect each channel separately (maybe I want to add delay to a channel and not the other one).

Not only for demoparties, but to make music after 10PM at home as well.

And yes, headphone amps is the external equipment that is a drag to get. They are sold in no stores anywhere and I don't understand it. They should have made it into consumerland long ago, at least I've seen them requested often enough

Oh, there are lots of them, none of them simply "sound too weak. amplify. sound extremely much more separated than in my stereo. mix.", and in all kinds of states of confusion.

They're usually battery-operated and in some big clump form factor you have bring with you, and I don't even think there's an option for reducing the stereo separation in 99.9% of them.



Extremely few will require 4-channel output, and if they do they will prefer an external line-in mixer with lots of possibilities.

Lots of equipment have the standard L and R white and red RCA outputs. Unlike the other equipment, the audio doesn't come pre-mixed but is harshly separated 100%. With a chip and few resistors, this could be fixed more cheaply and solve the original hardware design problem.

It would instantly make all games and demos sound better, without everyone rushing out to get the extra equipment to do it.

[Amiga1992]

Yeah but where will you put the sound volume knob and stuff? That is what I am getting at here. It sounds too much for the motherboard.
If there was a way to add a headphone amp with volume control that doesn't need case modifications, I'm all in for it! A headphone amp WITHOUT volume control is USELESS because it will be TOO LOUD and ruin your hearing.

I actually bought a FIOS headphone amp and it worked well but I didn't do a proper volume circuit. I have used it at Datastorm a couple of years ago.

If you wanna make music at home after 10PM and want to use headphones, as said before, get a small sound mixer. Something cheap but good from Mackie like the MIX8 or MIX5 will sort you out. Connect the Amiga outputs each to a mono channel, and pan (or not) as you please, and use headphones. That's what us musicians have, an outboard mixer, and it doens't cost an arm and a leg to get.

As I said, IF there was a way to include headphone amplification with volume control in the motherboard in a way that doesn't affect the case design, I'm game.

[dJOS]

Tbh unless this Amiga reloaded board takes the approach of the original Phoenix 1000 replacement board and brings significant upgrades I won't be buying one.

[Daedalus]

Anyway, what are you going to be making music with before 10pm? Surely whatever speakers/amplifier/TV you're using for your sound has a headphones output on it? That's where you want to be plugging in your headphones, not adding extra parts to a motherboard to convert line-level audio to headphones output that most people don't want. I know everyone's different, but I've never wanted to plug headphones into any computer or console since I've always used a proper amp for sound output.

At the end of the day, adding all these extra, cheap parts that everyone's asking for will all add up and make the board far more expensive for the end user. It's not just the cost of parts - there's extra assembly, design time, simulation and testing involved, all of which adds to the final price.

[dJOS]

The board would be better value if it didn't come with key parts missing. E.g. Color video via RGB or svideo or even better HDMI.

I don't mind the CPU approach, that is sensible.

[Mrs Beanbag]

indeed... let's not unnecessarily overcomplicate an already daunting project. A 3.5mm jack instead of phono output is a perfectly reasonable change, though.

Agreed, nothing wrong with that either.

[demolition]

Headphone output is not required, however a stereo mix adjustment would be quite useful, not only for headphones but also for speakers.

[Photon]

Well, it's in WinUAE for a reason, and it could be in an Amiga for a reason. The reason being the original output is hard panned L and R and it's been a bad thing for 3 decades. It was just an idea to put the annoyance straight in a real new Amiga model. But never mind. I'll just ask Jens, he'll say no, and I'll build it myself. Beats dragging a half Amiga size mixer+PSU just to get usable headphone output.

[Amiga1992]

I'm a lot more worried about a shitty black and white composite output instead of SVideo. That really needs to go. Jens, pwetty puleeeez!

it's trivial to implement in an emulator.

Putting it "right" right would be modifying Paula so you could set independent Left and Right volume levels for each channel in software (in a backwards compatible way).

But for now, i already posted the £2.79 solution:

[Retro1234]

ATX motherboard would be cool
what about a cpu slot would that be possible?
anyway Good luck Jens

[Mrs Beanbag]

motherboard with height of ATX and width of Flex ATX should fit inside A1200 case easily. only problem is the rear panel.

maybe A600? can't find dimensions for an A600 motherboard

Yes, I saw that and ignored it as troll bait, since it doesn't help anyone. Curious.

And yeah, just add some volume registers plus the missing mixing capability to a custom chip register that nobody has been able to clone in 30 years. How hard can it be!?

Again, not the most helpful suggestion.
