You have two options:
- Play-mode Command interface
- Setting Command interface (uManager)

New filters at moredamfilters

i feel a little stupid unfortunately im aware of these tutorials but i still manage to be clueless
in uManager is it?
example
is it "set filters = 04 bypass FIR1, 384 ksps"
In play mode you type: F4 or F5 or F6 or F7 (not the function keys!) for selecting one of the 4 filters
When you go into the uManager (+++) you type:
set filters = Linear
or
set filters = Mixed
or
set filters = Minimum
or
set filters = Soft
Linear, Mixed, Minimum, Soft corresponds to F4, F5, F6, F7

set filters = Linear

set filters = Mixed

ive The v099 Party Pak downloaded onto the dac
how do I select one of these filters
I appreciate your patience
That sets default filter bank when the board is powered on. It doesn't change current settings IIRC. Use short commands available outside uManager for that.
$ dam1021.py -f 1

I was wondering if anyone who has tested this could give an opinion on if the 0.01/0.02 resister version was enough or if I would achieve better results switching everything to 0.01%. Also is the factory vref mod enough or is it worth modifying that also?
I was hoping to connect this to a Pi2 via I2S, if I can get the Pi2 powersupply right.
I've got a perreaux dp32 (es9018) to compare it to, but the output on the DAC is louder on one side and they aren't returning my phone calls

The volume control goes as high as +10dB digital full scale, so at max volume the dam will distort on most modern program material.
In my opinion it would be great to have a choice in the firmware for 0dB max Volume. Right now I have a serial resistor in between the 10K pot and the dam to limit the volume to 0dB.
Found the value by paralleling resistors until it worked...I am not next to the dam right now so I cannot have a look...sorry
New Soekris DAC/AMP and standalone DAC
Latest DAC/AMP combo from Soekris at the recent RMAF show CANJAM AT RMAF 2015 – BRIAN MURPHY | Headphone.Guru
The interesting take away is that the DAC/AMP board supports DSD.
The standalone DAC board on the side also looks interesting and different from the DAM, it looks smaller and the connector laayout is also different.
The is a mention of a DAM2021 on the soekris.eu site noting concrete, maybe a typo

An externally hosted image should be here but it was not working when we last tested it.

The Soekris.dk site mentioned something about an OEM board (checked a couple of days back). Maybe the standalone DAC board in the picture is that
The DAM2021 reference seems to be a typo. Refers to the firmware update for the older 0.02% boards last month
Soekris now has more details, Nov 2015 estimated ship
Soekris Engineering, Inc. | products dac1101
The OEM board is probably the DAM1121
Here is to hoping Soren has the DSD functionality for the DAM1021 boards soon as the OEM board is shipping with DSD.
