: 2024-02-22 11:14:51

1.48kHz sampling frequency DSP processor, 24-bit A/D and D/A conversion; 4 inputs and 4 outputs DSP module.

2.The input mode can choose analog input, AES digital signal input, and DANTE input. Different signals can be input at the same time. It is equipped with a switchable switch and can set the signal priority.
3. The output channel temperature is visually displayed on the display screen, and the temperature status of the power amplifier can be monitored at any time.
4. Power amplifier protection indicator light, the PRO indicator light is always on when the power amplifier is in protection state.
5. Quick copy function; copy the adjusted parameters to other channels.
6. Configure signal generator; white noise; pink noise; sine wave signal.
7. Output 4 channels are configured with FIR function; FIR frequency division filter: Taps range is optional between 256 and 512, can be attenuated and has optional time window type; FIR parameters are generated by the machine itself or import the generated FIR file from a third-party application.
8. Scan USB devices and network port devices with one click, and automatically connect after scanning the device; the network port can be debugged with multiple machines, and up to 250 devices can be online at the same time.

This DSP continues the multi machine debugging of the previous 2U DSP, with a 4-inch screen touch control and software control function. And more features have been improved. Like the FIR function, the advantages of FIR filtering include arbitrary and precise control of the amplitude and phase characteristics of the filter, independent control of amplitude and phase, and the possibility of achieving maximum phase characteristics through absorption. Adopting AES interface, it is one of the standard interfaces for transmitting digital audio, which has the advantages of stability, reliability, and easy connection.Moreover, the new Dsp software has more complete and precise functions.
