All In One Mixer/PC Project

[Chris8477a]

Hi Everyone...

Well this is my first post to let you know what my plans are,

Basically, I want to build a complete "All In One" Mixer/Scratch/PC, (With folding screen)

I have been busy researching schematics and implementing my own with a few tweaks, I have attached these. I have tried using CAD (hopeless case), so did it using Excel, it gives you an idea and I can easily adjust it.


For the Mixer sofware i will either be using PCDJ or VDJ, hence alot of the main mixer controls will be map'd via MIDI utilising stripped USB Gamepads.

The PC will be a SFF motherboard along with some of the features (USB cards, Dual Monitor outputs CD drive etc)

Internal and external Speaker options/ Headphones(controlled via PC Outputs)
---------------------------------------------------------------------------------

OK now for the help.....

On the schematic, I want to introduce a Reverb circuit for the microphone inputs - All individually controlled (1 in 1 out type of thing)

I dont want and echo, echo, echo but I want a fading away toneeeeeeeeeee lol


Please help, I really have no idea about this bit, I have tried to find an analogue/mono schematic to no joy....

many thanks and thanks for anticipated assistance..

Chris.😕😕😕

I think VDJ has effects in it so you wont need an external echo circuit.

Hi and thanks for the response, Vdj does have an effects panel
However I will not be running the Microphones through the PC, inturn VDJ won't have an effect on the vocals, hence the requirement for a Pcb/schematic that is built into the main input schematic.

Regards

Chris.

Circuit design (CAD) Updated

Hi All

Have finally got a CAD program (lol) have looked at a few things from what people have been saying, trying to understand them and using the diagnostics on the program I have attached the following schematic..

Am I getting close...


Please please please,, if I have made any errors,, can you explain in the simplest terms possible as I am learning. Please explain certain weird and wonderful terminology lol

thanks and really appreciate all of your help.

Chris.

LM358 pins 2 and 3 need swapping.

LM358 pins 2 and 3 need swapping.

Corrected,,, are there any more?? are all the values correct aswell as Capacitors. Do I need to have + polarised caps???

Thanks

Chris

Thanks

Chris

Make all capacitors 1uF and above polarised the rest are best none polarised.

Okay - Circuit Updated again...lol

Make all capacitors 1uF and above polarised the rest are best none polarised.

Have actioned all suguestions,

hows it looking now??

many thanks
