The Danville Signal Processing dspNexus 2x8 prototype is here and making music. Unit has two new AKM AK4493 and two new AK4499 DAC boards installed. The ADC is the great sounding AK5397.
Starting with the new headphone amp capability using Windows 7 and Audio Weaver for first testing. Using my HiFiMan HE500 headphones and sounding very good and no problem with plenty of headphone drive.
A new HAL MS-5 Music Server running Windows 10 is built and getting loaded with software to run the dspNexus 2x8 for the testing with the Monoliths and Magnetar speakers.
This unit has a powered mic input on front with separate ADC for measurements.
The Raspberry Pi 4 2GB is installed and as software updates are made it will be running Raspbian Buster OS and measurement software like Room EQ Wizard. The I2S bus is connected to the DSP and clocking will be from the DSP low noise clocks. Will be testing with Linux based music players like Audacious and Audacity for recording.
This chassis is only for the prototype. Production units will have a new style of case similar to the one from the AXPONA2019 show.
