The prototype of the Danville Signal Processing dspNexus system was debuted today at AXPONA 2019 running The Monoliths speaker system and the new HAL MS-5 Music Server.

This is their next generation DSP product for digital crossovers and much more.  Not sure if I told that to corndog71 when he stopped in for a listen.

This will either be an 8 channel or 16 channel DSP processor with upgradable DAC modules.  The entry level DAC will be the AKM AK4493 DAC with the high end DAC being the latest AKM AK4499 that they are working with samples of at this time.  For the debut it is running an AKM AK4495 like the dspMusikLCD.  The show system is a prototype 8 channel system.  The ADC is the AKM AK5397 like the dspMusikLCD.  All ADC's and DAC's have local low impedance regulated linear power supplies.

The system will be available with DSP Concepts Audio Weaver version 7 software to program the DSP for use with an external PC.

The system will have analog, USB2Audio, S/PDIF and Bluetooth HD inputs with IR remote switching.  Volume, mute and function select will be by the remote as well as front panel control.  The USB2Audio input is XMOS and ASIO compatible for both Windows PC with a USB driver and native for MAC OS.

There is a phantom powered mic input with USB output on the front.  Next to it is the headphone amp jack for automatic selection of speaker or headphone use when the jack is inserted.  Volume control is the same for both styles of outputs.

There is an integrated Raspberry PI3 that is also connected via I2S Bus to the DSP with low jitter clocks supplied to the PI3.  This will be for future expansion to making measurements of speakers and rooms for crossover use and room correction.

The slated production is in June 2019 and I will update this as it gets closer.

Here are some pictures of the system in the prototype chassis:

Latest news is that the updated dspNexus motherboard and DAC boards have been built and new prototype in build to send for testing with The Magnetar speakers.

Hope to see this Jan 2020 for listening trials.

Hi Rich,
Is the dsp you do similar to what the Dirac software does?

Nick,
The dspNexus does four things once it is released.

First is acting as the DSP processing and HiRez DAC's for active speaker systems like The Monoliths or Magnetar speaker as up to a 4 way stereo crossover.

Second complete system front end capability with analog and digital inputs and remote control of functions.

Third is that the latest system should have the capability to run room correction and take a calibrated measurement mic to make the measurements needed.  That is something Danville has been working on. 

Fourth is the Raspberry Pi 4 running for making speaker and room measurements, acting as a Music Player of Roon End Point for Ethernet playback, etc.

A lot of new features not in the dspMusikLCD system.
