Kramer Electronics 90-70818090 3G Hd-sdi Standby Switch

Product Description

The KRAMER ELECTRONICS 90-70818090 is a 2x1:2 3G HD-SDI standby switch designed for professional AV signal processing applications. It accepts two 3G HD-SDI input sources and routes the active signal to two outputs, providing seamless source switchover in broadcast, production, and AV distribution environments. This type of standby switch is used to maintain continuous signal flow by switching from a primary source to a backup source when the primary fails or is manually bypassed. AV systems integrators and broadcast engineers are the primary installers of this device.

This unit is suited for professional video infrastructure where uninterrupted 3G HD-SDI signal delivery is required. Typical applications include broadcast facilities, live production rigs, digital signage backbones, and installed AV systems where source redundancy is critical. The 2x1:2 configuration allows one active input and one standby input to feed two downstream destinations simultaneously, simplifying redundant signal architecture in rack-mounted or equipment-room deployments.

Key Features

• 2x1:2 switching architecture: two inputs selectable to two simultaneous outputs
• Supports 3G HD-SDI signal standard for high-definition video distribution
• Standby switching capability maintains continuous output during source failure or changeover
• Designed for rack-mount or professional AV equipment-room integration
• Sold as a single unit (EA)

Compatibility

Designed as an OEM-style replacement or system component for professional AV signal processing setups utilizing 3G HD-SDI infrastructure.

Installation Notes

Installation is typically performed by licensed AV systems integrators or broadcast engineers familiar with SDI signal distribution. Power down the receiving equipment before connecting or disconnecting SDI cables to avoid signal interference or equipment damage. Follow applicable AV and low-voltage wiring codes for your jurisdiction when integrating into a permanent installation. Verify that all upstream and downstream SDI devices are compatible with the 3G HD-SDI signal standard before commissioning.
