Brand New AES/EBU Digital Audio Delayer
ZHC-868D Series programmable digital audio delay device is the broadcast exclusive product, which uses a high-speed digital signal processor (DSP) for delay and an embedded microprocessor for real-time control for realizing the function of wide range digital audio delay. In broadcasting system with the synchronization of FM and AM, it is the indispensable equipment to ensure the audio synchronization; in the application of real-time broadcasting, it can delete part of the content during the living broadcast so as to ensure the broadcasting quality.
Features:
- Advanced technology, adopting 32 bit fixed point DSP making the system functions more powerful and the performance more superior.
- Applicable to all digital audio delay.
- The digital audio needs no A/D and D/A, it is directly converted without additional signal-to-noise and distortion.
- DSP control and process, delay accurate, high-quality audio output
- Delay does not change AES audio sampling rate
- Can through directly when power failed
- Delay be controlled by program
- Wide-range delay
