Main / Audio ADC, DAC, delay lines / PAAD-3102
PAAD-3102 series 2-channel audio ADC/delay line |
PROFLEX™ PAAD-3102 series 2-channel audio ADC/delay line accept two analog audio input signals for sampling and quantisation with 24-bits accuracy, the sampled audio is converted to the AES/EBU standard. Manual and automatic (the "audio follows video" mode) audio delay adjustment.

The remote control and management from a PC
All the “PROFLEX” modules are remote controllable from a PC. This facility is available if a rack is fitted with a CPU module (ordered separately).
