The yellobrik CQS 1441 is a compact converter that enables single link 12G-SDI signals to be converted to quad-link 2SI 3G-SDI and visa versa (i.e. quad-link 2SI 3G-SDI signals to be converted to 12G-SDI). 6G to/from quad-link 2SI 1.5G conversions are also supported.

Note. This module DOES NOT support SQD or “Square Division” quad conversions, only 2SI

With many facilities still running in a 3G environment, there are many requirements to integrate 4K/UHD signals in 12G SDI into the infrastructure. The CQS 1441 yellobrik enables users to convert UHD signals between quad-link 2SI 3G and single-link 12G SDI. Plus, since its bi-directional, a single yellobrik can be used for both inputs and outputs for the application at hand.

Another key feature of this new yellobrik is the 12G fiber option and a 12G loop output. For example, a 4K UHD camera or other input source can be connected via 12G fiber to the yellobrik’s SFP fiber input and the 12G loop connects the yellobrik to a 12G video mixer for signal switching.

The CQS 1441 also offers a 12G fiber to 12G coax conversion feature. Regardless of whether customers choose fiber or SDI, they can have the simplicity of running 4K over a single connection.

The intuitive and user-friendly yelloGUI software gives users access to a host of advanced settings and adjustments of the CQS 1441, as with other compatible yellobriks with the availability of yelloGUI, users have an enhanced level of yellobrik configuration for advanced features & settings. yelloGUI is complementary to all yellobrik users.

The CQS 1441 is fully compatible with the unique yellobrik rack frame for high density applications and additional redundancy.
