Professional NTP/LTC Converter
The professional NTP/LTC converter is designed to synchronize from an NTP reference available on the LAN network and generate LTC timecode with millisecond precision. It is ideal for broadcast and audiovisual installations that require a reliable NTP to LTC conversion chain.
Signal Interfaces:
- LAN / NTP input: Synchronization from an NTP reference over Ethernet
- LTC balanced output: XLR male 3 pin
- LTC unbalanced output: BNC connector
- GPIO: Programmable inputs and outputs
Main Features:
- NTP Synchronization: Receives timing from an NTP reference via LAN
- Timecode Generator: Creates LTC from the NTP reference
- Converter: One-way NTP→LTC conversion
- GPIO: Interfaces for custom applications
The web interface allows complete configuration: IP addresses, primary/secondary NTP sources, timezone, automatic/manual offset, GPI/GPO for programmable events. The OLED display shows status, IP addresses, configured NTP sources, current date/time and last synchronization. Ideal for TV studios, broadcast productions, post-production and professional installations requiring absolute precision.
