I'd recommend detaching the LCD and the control knob from the PCB (e.g., connecting them with wires and Molex plugs), so they can be moved around and installed in different locations. If the screen and the knob are fixed in place, it'll be hard to make this panel unit look good in an aluminum case (remember, most of us don't have professional machining tools 😉).
Along the same lines: it would be useful if the LCD came with a metal frame that has screw holes. That way, it could be attached to the outside of a case and all you'd need to do is drill a small hole for the wires.
It may be too late to make these changes now . . . but it's stuff that would be cool to see in the next version (the "modular" one? 😀).
Yes, yes, yes! There's no point in having an LCD screen when you don't have the machinery to cut out room for it in an enclosure.

Love it.
Probably LCD would be nice on a board smaller than it or same size so we can mount it easier. I agree with the other guys.

Thanks guys, for your valuable advice.
I think I have to finish current one first, as good as I can. And then we will think about other form. It will be a exciting experience for me.

1st thing you need to remember is that the display must be visible for a distance, I.E. 3 meters app. Too small font will make it useless as you have to get up every time just to see what it is displaying.
2nd thing is the color of the LED. White is in my oppinion neutral although red or green is pleasing to the eyes at night if contrast allows it.
3rd Is there any way to dim the display or timer turn it off when not in use and watching movies?
4th is there no way to support 192khz/24bit material with this chip (or in general)?
The module idea is great as it minimizes your workload as you only need few basic boards and som controller, psu and display. However, is there any way to make it accept blu-ray formats like DTS-MA and DD-HD (maybe you set the player to decode but output PCM via coax?).
I am totally amazed at the speed you are doing things at. Producing new boards at record pace (compared to the typical DIY pace anyways 😉 ).
Please do let me/us know if you want to brainstorm future features before jumping into production. I personally have no degree in electronics, but am very interested with clear goals for the product I might buy (was your 2050 v2 until you started this project with the 5.1 in the distance 😉 ).... and of course financial support once the project is ready for shipping 🙂.
BTW I seem to recall that some apogee all digital chips support fairly advanced x-over settings. Is this the case with your current amp also (and/or will be in a future 5.1 model 😀)?
I also think that support up to 24/192 would be great! Especially if balanced input is supported
I'd argue that this feature is more important than either the color of the LCD or the size of the text on it. A single bright LED in the wrong place can be annoying, so an overly bright LCD display would be a serious design mistake.
An "auto off" setting for the display will probably suit most people, who will rarely touch the controls after they've finished configuring the amp. The DIYers who want their display to be as noticeable as possible (to impress others? 😛) can always disable this feature.
Very useful suggestions. I think some of the ideas are already on the way.
For DTS and DD, I'm also have some idea, but will not in this one.
I will post my work before public it.
I think we will support 192kHz when balance input, but before making sure, I have to test more.
I agree too. So the back-light of LCM will be auto-off when there is no setup action. 😉
I am also excited about this new amp, curious to hear how it sounds. I'm thinking about wouldn't it be awesome if we had 4 or 6 channels and could set the crossover digital. Then we could run one channel to each speaker element (2 or 3 way) without using any analoge crossover. I guess the level would need to be adjusted between the channels also.
Anyone tried this with another setup?

That sounds like what I read about the apogee amp (from the klipsch omnisphere Xbox xpeakers). It is a very nice idea and all active xover, digital surround amp is my next big project 😀. As far as I remember you could change xover points, slopes etc. in the software for the chip. It looked very cool.
We need a hifimediy solution to his problem (make it modular to suit more people than me 😉 ) 😀

Maybe a little inspiration 🙂

Thanks Havoc08.
And here is news:
Finish the power off data saving function.
Make channel icon bigger.
Add a Relay on/off signal on LCM.

a stupid comment as a pretext to follow-up this topic 😉
3 digits for temperature display (028°C in the above example) is overkill i guess. We don't expect it to go over 99°C 😀 display simply 28°C would be nicer.
hifimediy, keep up good work 🙂 If this sounds as good as your AMT2050 v2 amp with a DAC, you'll rule the world 🙂
