Hi guys
I have a DAC CEC DA1N I'm searching for service manual, someone have it ?
The display has low brightness someone know why ?
I would also like to make a modification, adding an external PCM, to get to 192 K. For this I provided an mp3 signal on the USB port of the DAC and I thought I would find the analog audio on pins 28 and 29 of the PCM, but measuring with the oscilloscope I find nothing.. and I don't understand why ... if someone can help me... thanks

The VFD display may be at the end of the line.
I don't have any technical documentation, sorry.
Yes, I connected a computer to the USB port and playing an MP3 file while I listen to it I measure the DAC outputs and I find no signal on pins 28 and 29.
Yes, it appears on the display and you can hear the music but with the oscilloscope I should find the signal on pins 28 and 29
