LT4448
- Input / Output:
- Provides 11 channels (single channel consists of primary input, backup input, and output)
- Input Signal Switching:
- Input / Output:
- Provides 11 channels (single channel consists of primary input, backup input, and output)
- Input Signal Switching:
- Relays are used to switch channels 1 to 2
- Electronic switches are used to switch channels 3 to 11
- Channels 4 to 11 are also equipped with high-speed, error-detection circuits
- Provides 3 channels for LTC
- Input Signal Selection:
- Channel 1 and 2 inputs are dedicated inputs for SDI (3G/HD/SD), NTSC/PAL Black burst and Tri-Level Sync signals
- Channel 3 to 8 inputs are dedicated inputs for NTSC/PAL Black burst and Tri-Level Sync signals
- Channel 9 and 10 inputs are dedicated inputs for AES/EBU digital audio signals
- Channel 11 input is dedicated input for word-clock signals (TTL)
- For LTC signals, dedicated LTC inputs / outputs (2Vp-p,differencial input) are provided
- LTC Channels:
- 3 LTC channels
- Each channel has 2 inputs (primary and backup) and 1 output
- Fault Detection:
- When input signal level error is detected, panel fault LED illuminates as well as panel LED that indicates channel causing problems
- Allows for quick notification of problem
- Channels 3 to 11 are equipped with high-speed fault detection circuits
- When interruptions occur in primary signal, enables switching to backup signal with barely noticeable disturbances on monitor
- Power Supply Start Time:
- Delay for starting the fault detection at power up can be set to approximately 1 minute or approximately 4 minutes, depending on rise time of connected system signal source
- SNMP Ready:
- Error monitoring over Ethernet network is possible
- Traps are issued for error detection, panel control, and remote control
- In addition, error details and DIP switch settings (except for user defined fault detection level) can be read as status information
- Included IP address configuration software compatible with Windows 7 (32bit and 64bit), Windows 8 and Windows 10
- Redundant Power Supply:
- Redundant power supply provides extra reliability
- Alarms are generated if power supply failure occurs
- Web Browser:
- Can be controlled by web browser

- Primary Input: 10 input (75ΩBNC Connectors) / 1 input (TTL, 75ΩBNC Connector)
- Backup Input: 10 input (75ΩBNC Connectors) / 1 input (TTL, 75ΩBNC Connector)
- Output: 10 output (75ΩBNC Connectors) / 1 output (+5V CMOS, 75ΩBNC connector)
- LTC I/O:
- Connector: D-SUB 25 pin ((Input and output)
- Input: 3 channel 2 input(PRIMARY,BACKUP)
- Output: 3 Channel 1 output
The Leader LT4448 Changeover Unit automatically switches from the primary signal to the backup signal when problems are detected in the primary signal.
A single LT4448 provides 11 channels. These channels can receive LTC, SDI, NTSC/PAL black burst, HD tri-level sync, AES/EBU digital audio, and word-clock signals. SDI signals are switched with relays. All other signals are switched with electronic switches.
Redundant power supplies are included. Alarms are generated when errors occur. The LT4448 can be used in combination with LT4600A, LT4610 and LT4611 Units.
