Leader LT 4448

Opis

LT 4448 to jednostka przełączająca, która automatycznie przełącza sygnał z sygnału podstawowego na sygnał zapasowy, gdy zostaną wykryte problemy z sygnałem podstawowym. Dwa systemy sygnałów wejściowych (podstawowy i zapasowy) są podłączone do LT 4448 i LT 4448 wykrywa błędy w amplitudzie pierwotnego sygnału wejściowego.
Pojedynczy LT 4448 zapewnia 11 par kanałów BNC i LTC. Kanały te mogą odbierać sygnały SDI, NTSC/PAL black burst, trójpoziomową synchronizację HD, cyfrowe audio AES/EBU, Word-clock i LTC.
Może być używany w połączeniu z LT 4610/LT 4611/LT 4600A.

Features:
• Provides 11 channels (a single channel consists of a primary input, a backup input, and an output) on a single unit.
• Relays are used to switch between the primary signals and backup signals of channels 1 and 2. High-speed electronic switches are used to switch between the primary signals and backup signals of channels 3 to 11. For LTC, switching is possible between primary signals and backup signals for three inputs.
• The input signal type can be selected. On channels 1 and 2, you can select SDI signals (3G, HD, SD), NTSC/PAL black burst signals, or HD3 tri-level sync signals. On channels 3 to 8, you can select NTSC/PAL black burst signals or HD3 tri-level sync signals. Channels 9 and 10 are exclusive to AES/EBU digital audio signals. Channel 11 is exclusive to word-clock signals (TTL input). LTC channels are exclusive to LTC signals (2 Vp-p differential input).
• LTC channels provide three systems of two inputs (primary and backup) and three systems of one output. In addition, an LTC cable (sold separately) can be used to connect to a LT 4610 (Sync Generator).
• A delay for starting the fault detection at power up can be set to approximately 1 minute or approximately 4 minutes depending on the rise time of the system signal source that the LT 4448 is connected to.
• Redundant power supplies are available for increased reliability. Alarms are generated when errors occur.
