Main / Audio ADC, DAC, delay lines / PADL-3101
PADL-3101 series analog audio delay line |
PROFLEX™ PADL-3101 series analog audio delay lines provide manual audio delay adjustment or automatic "audio follows video" mode (available if controlled by "PROFITT"s network).
Features
- 24-bits Delta-Sigma convertion
- 48kHz audio delay line sampling rate
- audio delay adjustment up to 1.3s
- user-presettable 0dB or +6dB output level (+18dB or +24dB maximum output level)
- audio gain presets in the -12dB...+12dB range
- two balanced analog outputs (one stereo pair)
- built-in test signal generator (1kHz and "mute")
