CZH868D AES/EBU Digital Audio Delayer Adopting32 bit fixed point DSP, To all digital audio delay

● 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. More →
