Quanghao, pls send me tracking number for the trafo. I cannot turn on my dac without trafo
Quanghao, pls send me tracking number for the trafo. I cannot turn on my dac without trafo
please see post : #1795
Just been running more tests...
DSD plays but PCM remains silent. The PCM rates are correct on the display though. Made one other observation which I did not realise previously - only left channel (right side output) works for DSD. Looks like something is seriously wrong? Shall try "swapping channels" on the firmware to see if it makes any difference.

Tried different permutations. The right channel (left side of the DAC) does not work with the Amanero. Still no PCM playback. Coax works fine - both channels work OK. No way for me to test optical and AES. I hope there isn't a fault. Really disappointed! Obviously, it might still be the Amanero at fault and will be grateful if someone can test it for me, or send me a module that is definitely known to work. Quanghao - are you sending me the parts we discussed previously?
The flat cable seems ok. Reversed it, measured resisistance perhaps I will resolder the sockets.
I am confused there is no Amanero applet on WCP should be ? Only the Sound applet with the supported formats from 44 to 192 did you speak about this ? There is no frequency setting at the USB driver in Device Manager.
That "PCM 44 KHz LOCK" is written to the dac's screen when I connect USB for example my Nexus 7 tablet. Then the d20 led lights on. Be continued ..
As I have tried to explain a few times....
USB input (Amanero):
DSD: ONLY right channel works
PCM: Does not work at all (silent but correct rate + lock on display). Works like DSD above if on-the-fly conversion to DSD
Tried JRiver (KS) + Foobar + HQplayer (linux) + mplayer (linux) + aplay (linux)
Tried different firmware revisions +/- swap PCM/DSD channels (various permutations)
Coax (44.1):
Works fine (Left and right channels)
So, i Think your DAC module have an electric problem and it should be changed.
Hi Quanghao, I am not certain that it is the DAC board that is at fault. The fact that the display shows the correct lock and rate suggests that at least the link between the amanero / controller and ES9018 is correct ? I presume the DAC board is easy enough to dismantle? I guess I will have to take the back of my chassis first? I don't want to break anything! I still think it might be the controller / firmware that is at fault ?
I think one of these two options would be best:
1. Is it possible for you to send me the controller / flat cable / another amanero and perhaps a new DAC board plus the pickit as discussed previously? If none of these new components work, I will just have to return everything over to you. If I can get it to work, I will then return the parts that are not needed.
2. Alternatively, I can return everything you sent me (with my amanero) to either check everything once again to make they are all working or to refund my payment.
I certainly prefer Option 1, and I think would be the cheapest in terms of cost of postage for both of us. I am happy to pay a deposit for the extra parts if you wish. I just want this working so that I can listen to music!
I presume that is the controller / flat cable + USB ? Can you send me a porgrammer as well? Thanks.
Thanks quanghao, I would like to understand what is the problem before sending back or not.
You would not ask this if you remembered what I wrote earlier, I think. Even so thanks for the support.
please add your problem or correct the problem info
This is the current list:
1) smoothquark
problem: with USB input DSD plays fine but PCM is completely silent, right channel does not run on USB input but coax all ok
solution: Amanero, controller and flat cable will be changed
2) judo
problem: USB input work only at 44KHz
solution: The DAC module will be changed
3) Erlend Sæterdal [SOLVED]
problem: lcd does not work
solution: the lcd controller module has be replaced
4) masterkey [SOLVED] [waiting the confirm]
problem: no work with usb input but work good with coax and optical input
solution: masterley will receive a new DAC module
5) misterwolf , Halook [SOLVED]
problem: spdif does not work with some non standard sources
solution: eliminate the 75ohm and add a 1uF capacitor after the input transformer (cut the pcb jump).
6) MattMax - [tested ?]
probem: tweeters of my loudspeakers emit a hissing sound when the DAC is on mute
solution: see point 2, apply #1586 and add a caps to filter high freq. on DAC output
7) Erlend Sæterdal [ tested ?]
problem: More than 11 mv offset with OPA 1612
solution: have you tested different op-amp ? have you apply the mod. #1586 ?
8) bertchai [tested ?]
problem: using Mac 0.5s at the beginning of the song is missing/silent
solution: try the version with automute delay reduced, post #1724
9) Some [SOLVED]
problem: Amanero USB module not recognized from PC
solution: the USB pins on pcb touch the DAC shield, so cut this
10) Some [SOLVED]
problem: lcd wrong characters
solution: change the flat cable or solder the wires
11) Many [SOLVED]
problem: firmware update
solution: the best method is to use the Pickit2 available on Ebay shop and Amazon, there are some cheaper clone
12) Many [SOLVED]
problem: little oscillation on power supply shunt
solution: follow post #1586 and #1626
