Key Features

Provides 11x channels with single unit
Single channel consists of primary input, backup input, output
Relays switch between primary signals/backup signals for ch. 1/ch. 2
High-speed electronic switches switch between primary signals/backup signals for ch. 3 to ch. 11
LTC switching possible between primary signals/backup signals for 3x inputs
Selectable input signal types
Selectable SDI signals (3G, HD, SD), NTSC/PAL black burst signals, HD3 tri-level sync signals on ch. 1/ch. 2
Selectable NTSC/PAL black burst signals, HD3 tri-level sync signals on ch. 3 to ch. 8
AES/EBU digital audio signals on ch. 9/ch. 10
Word-clock signals (TTL input) on ch. 11
LTC signals (2 Vp-p differential input) exclusive to LTC channels
LTC channels provide 3 systems of 2 inputs (primary/backup), 3 systems of 1 output
LC2183 LTC Cable (sold separately) can connect to LT4610 Sync Generators
Delay for starting fault detection at power-up can be set to 1 min./4 min.
Delay depends on rise time of system signal source connection

Details

The Leader LT4448 Changeover Unit is compatible with the LT4600(A) Video Generators and LT4610 or LT4611 Sync Generators. When combined with the compatible instrument, it automatically switches from the primary signal to the backup signal when problems are detected in the primary signal. Two systems of input signals (primary and backup) can be connected to the instrument in which the instrument will then detect errors in the amplitude of the primary input signal. A single LT4448 provides 11 pairs of BNC and LTC channels. These channels can receive SDI, NTSC/PAL black burst, HD tri-level sync, AES/EBU digital audio, word-clock, and LTC signals.
