[How to do instruction] AUDIOPHONICS RaspDAC Mini Kit - I-Sabre ES9038Q2M

[Jempie]

Hi Rikardo,

i have the same mini kit, is there a way to change the output level?
there is a big difference between my cd player 2,25 volt output mini kit 1.5 v.

If i see on alsamixer there is nothing possible to change i disabled the software volume.

Thanks

I don't think there is any other option on software base apart from 'ALSA volume' under moOde settings

 

Another option would be to use inline attenuators on your CD player

Hi Rikardo,

ok i will try that the attenuators sorry that make them sound not good.
I have also the Sabre 9023 also the same problem, but i cannot change the setting with alsa

thanks man

Don't forget to set MPD Hardware volume setting, because it remains on software after driver installation.

About the output voltage @0dB, the only way to increase it is to change resistors to increase OPA gain, that we do not recommend.

Audiophonics,

Let me know wich resistors i have to change
to get an higher output is now to low

You have to replace R8 R9 R12 R13 from 1.24 to 1.5K ohm to get 2V RMS output

Hi Audiophonics,

can you please add a picture where the resistors are located on the board.
what was the original output?

Thx,
Jempie

[audiophonics]

Near I/V OPAs

Standard gain is 2V p/p, 1.5V RMS

Hi,

Thx for the guide, it works very well.

Just one little problem, in /etc/lirc/lircrc:

Code:

config = /usr/bin/mpc previous

should be:

Code:

config = /usr/bin/mpc prev

It doesn't work otherwise.
