Signal Distribution
The BZBGEAR BG-3GS14 is a 1x4 3G-SDI splitter that takes one SDI BNC input and delivers four simultaneous SDI BNC outputs. It supports resolutions up to 1080p@60Hz and data rates from 270 Mbps to 2.97 Gbps. This unit suits broadcast engineers, AV technicians, and live-production crews who need reliable multi-display monitoring or signal cascading from a single source. It is not for buyers who require HDMI or DisplayPort connectivity, or those needing more than four outputs from one device.
Thermal and Power Behaviour
The compact metal enclosure measures 155×86×23.5mm and weighs 266g, using passive cooling with no internal fan. Silent operation is guaranteed in studios, OB vans, or quiet control rooms. Power consumption is low enough for standard 5–12V DC supplies commonly found in portable kits, so the splitter adds negligible heat or acoustic load to existing racks or camera bags.
Build and Daily Use
A rigid aluminium chassis protects the PCB during frequent transport and on-location rigging. Locking BNC connectors prevent accidental cable disconnects when cables are tugged or routed through tight paths. The device relocks the SDI signal, extending SD feeds up to 200m, HD up to 120m, and 3G up to 80m without external repeaters. Colour-space support includes RGB and YCbCr 4:4:4, 4:2:2, and 4:2:0 at 8, 10, or 12-bit depth for flexible grading workflows.

Questions about this item
How do I install the BG-3GS14 and what is the step people often miss?
Connect the single SDI BNC male input to your source and up to four SDI BNC male outputs to displays; the step often missed is ensuring each BNC connector is fully locked by turning the bayonet until it clicks, otherwise the signal relocking and 2.97 Gbps bandwidth cannot be maintained.
What maintenance or replacement will the BG-3GS14 need over time?
The unit has no user-serviceable parts or consumables; its metal enclosure and locking BNC connectors are rated for years of operation, so only the external SDI cables may need replacement if they become damaged or exceed the 80 m limit for 3G signals.
What is the first limit that appears when running the BG-3GS14 continuously at 1080p 60 Hz?
The 3G-SDI signal reaches its maximum reliable cable distance of 80 m (262 ft) before signal relocking can no longer compensate, so cable length is the first constraint under sustained use.
