SMPTE Input Range for Response SMPTE Gateway
Description
The Response SMPTE Gateway receives LTC timecode for synchronization with other devices in the system. Audio signals are received via a 3-pin XLR connector.
Since SMPTE is an audio signal, it needs to be sent in a certain range for "loudness" so that the SMPTE Gateway can "hear" it correctly without distortion. If the signal is too weak or too strong, the Gateway may not process the signal at all, or may skip and be unreliable.
