DAC-END R (ES9018) full assembled board

[bobkojek]

Hi, my dac works, i only tried it with amanero usb.
Have some problems :
1. If i plug the usb cable first and i turn on the dac, the lcd display shows weird characters and i shutdown the dac without try to play music. But when i turn on dac first and then connect the usb cable the lcd display show normal.
2. About the button, is the center one for mute or standby the dac? Because button function for center and right ones doesn't meet with what printed on the pcb.

thanks
Nicko

Hi guys, halo, congratulations you got the DAC and run it.

The remaining friends, including the DAC + power transformer ....

I need to do the following to ensure the transportation and the best for you.

I am alone, just the kids just do these things, but very hard but fun:

1. all mounting screws on the bottom
2. installed power transformers
3. mounting screws on the front

4. installation screen controller

5. DAC board assembly and packaging shell +

You see attached picture

Thank you all for your trust.


A dac running is a pleasure for me!

How you are using the Amanero module ?

The DAC module have a jump to set external power supply for Amanero mdule but to use this configuration it is necessary cut a pcb wire on Amanero module.
I suggest to do this, here the photo to this operation.

Sorry probably I forgot to give info on this.

Hi Andrea,
I'm still using usb power to powering amanero module

Here's the post about modifying the Amanero to use the PS of the DAC and not USB.

Here for the jumper to set.

One more thing, for 2134 opamp replacement if i used opa2227p or lm4562 with opa627ap is it still ok? thanks again

 

[Erlend Sæterdal]

a separate power supply 3.3V for USB, you can simply use Jum.

And how to remove the power supply from the computer like this photo.

Thank you!

Could it be ok just to remove the L1 ?
