Why choose DSP Power Amplifier?
|
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 an automatic 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. Output amplifier protection indicator light, the PRO indicator light is always on when the 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. The 2U panel is equipped with a 4.3-inch touch screen, which can directly adjust the parameters to be adjusted by touch or connect to a computer to control through PC control software; |
8. The operation panel can store 30 kinds of user programs, which can be called quickly and conveniently. |
9. The device can be locked through software or panel to prevent misoperation |
