SWIT S-4611 Portable 3G/HD/SD-SDI to DVI-D Converter

SWIT S-4611 Portable 3G/HD/SD-SDI to DVI-D Converter

The SWIT S-4611 SDI to DVI Converter converts professional 3G-SDI, HD-SDI, or SD-SDI video to a DVI-D output for monitors, televisions, LED displays, and projectors. It supports broadcast signals through 1080p60 while also extracting the first two embedded SDI audio channels to a separate 3.5mm analog output.

A reclocked SDI loop output, meaning the converter regenerates the SDI signal timing before passing it downstream, lets operators feed another monitor or device without sacrificing the original connection. The DVI-D output follows the incoming format rather than performing resolution scaling, making this portable SDI-to-DVI converter useful for broadcast monitoring, studio integration, field production, and fixed AV systems.

The compact aluminum-alloy housing protects the BNC connections during production use, while bottom 1/4-inch mounting threads support camera or equipment installation. Three LED indicators show power, input, and output status at a glance. The S-4611 accepts 6-18V DC power and includes both an AC-DC adapter and installation plate for portable or permanent deployment.

Key Features

• 3G/HD/SD-SDI to DVI-D Conversion: Converts professional SDI video up to 1080p60 for compatible DVI displays and projectors.
• Reclocked SDI Loop Output: Regenerates and passes the incoming SDI signal to another monitor or downstream video device.
• Embedded Audio Extraction: Converts SDI audio channels 1 and 2 to analog audio through a 3.5mm output at a 48 kHz sample rate.
• Same-Format Video Conversion: Maintains the incoming video format when converting from SDI to DVI rather than functioning as a scaler.
• Status Monitoring: Three onboard LEDs provide visual confirmation of power, SDI input, and converted output status.
• Wide DC Power Range: Operates from 6-18V DC for use with the included AC adapter or a compatible field battery connection.
• Rugged Aluminum Housing: Unibody construction protects the converter and BNC connectors during studio and field production.
• Flexible Mounting: Bottom 1/4-inch threads and the supplied A-IP00 installation plate support camera, wall, and equipment mounting.
