AudioPhonics KIT Interface / DSP Controller - DCX Strong>
AudioPhonics presents its DSP Controller Strong>specially designed to interface with the Behringer DCX2496 but also other processors available on the market.
This setup gives you the option to 4 different digital sources and retrieve output 6 analog channelswith volume management andsymmetrical or asymmetrical .
Functions offered by this product:
- Regulated linear power supply for the DCX2496 as well as all additional circuits
- Selection of 4 digital sources
- Dismountability at DCX output
- Remote controlled volume control and encoder + OLED display
- RCA and XLR outputs
- Trigger output with tempo for amp control Li>
So you only need the DCX DSP card and the front panel./ P>
The general design basis for this product has been that it can be used and meet the electronicBehringer UltraDrive DCX2496, which has been a reference in the field of digital active filters for a number of years, unbeatable value for money. Strong>
And it is clear that all thethe latter will disappear when it is associated with this setup: Clock noise, power supply noise, residual ripple, digital input available only in AES / EBU, no volume control available, no source selection, etc.
tout what it takes to adapt this product to use in domestic Hifi.
Thanks to its card-based controller Arduino, editing of the editing, information displayed on the screen or any other parameter managed by programming is possible. (WM8805, CS3318)
Thus everyone with the necessary knowledge will be able to adapt the operation to its use.
The original program is available upon request to purchasers of this product, providing a basis for possible future developments.

/! \ Caution, This setup does not perform the function of converting the digital to analog signal, c'est interface for DSP or DAC.
This assembly can also be based on a Multichannel Digital / Analog Converter (DAC) operating as a control interface (Volume Management and Source Selection), or any other DSP.
Example of a board that can be used with the mounting in addition to the DCX2496:
MINI DSP 2x4
MINI DSP 8x8
HYPEX DLCP DSP
... or any other DSP with digital input and analog outputs.
