The miniDSP 2x4 HD is a versatile yet compact DSP engine with the input options you really need. What is lacking, though is a quality DAC option. Such a DAC can be added as an output option with full signal integrity using I2S.

This one-off unit has a small footprint, 128 x 128mm in a portable yet sturdy enclosure.

In addition to the miniDSP 2x4 HD there are:
- Soekris Engineering discrete R-2R sign magnitude DAC technology OEM Line DAM 1121
- Bluetooth 5.0 Audio Module BT5.0 CSR8675 Chip Support APTX-HD "Made in China"
- Power supply with 3 discrete DC-DC converters with low ripple and noise. The external wall plug can be replaced with a 5V LiOn battery.

The DAC board replaces the internal DAC whannel 3-4. The board is very handy and easy to use. soekris.dk/dam1121.html .

The unit can be used as a general pre-amp with a bank of IIR filters for room- and speaker correction driving a bi-amp setupo.
Also, earphone correction is used with the FIR filters,
Sound is excellent.
