Appendix A Specifications
AES/EBU Digital Audio
LTC Input/Output
Parameter Specification
Standard AES3
Audio Inputs 4 Channels per video input; 2 dedicated BNC connectors per video
input; two channels per BNC connector
16 Channels of embedded audio from video input.
Supports 48kHz, 16 bit, 20 bit, or 24 bit digital audio sources.
Audio Outputs 4 Channels per video output; 2 dedicated BNC connectors per video
output; two channels per BNC connector
16 Channels of embedded per video output.
Audio mapping is direct and fixed, the first four channels are the same
for AES and embedded, the last twelve channels are only embedded.
AES outputs are active at all times; embedded audio insertion on
outputs can be disabled.
Audio is output using a 48kHz clock derived from the video reference.
Supports 16- or 24-bit media.
On playout, audio is synchronized with video as it was recorded.
Compatible with AC-3 and Dolby-E
Input Impedance 75 ohms, unbalanced
Audio time shift Configurable relative to video for both record and playout.
Parameter Specification
Standard SMPTE 12M Longitudinal Time Code, AC coupled, differential input
Number of Inputs 1 per video input - Female XLR
Number of Outputs 1 per video output - Male XLR
Input Impedance 1K ohm
Output Impedance 50 ohm
Minimum Input Voltage 0.1 V peak-to-peak, differential
Maximum Input Voltage 2.5 V peak-to-peak, differential
Nominal Output Voltage 2.0 V peak-to-peak differential.
LTC Reader LTC reader will accept LTC at rates between 1/30 and 80 times the
nominal rate in either forward or reverse directions.
LTC Transmitter LTC transmitter outputs LTC at the nominal frame rate for the selected
standard at 1x speed, forward direction only.
