CQS 1441 is a bi-directional 2SI quad-link to single-link converter manufactured for compatibility with SMPTE standard SDI signals of 1.5Gbit/s to 12Gbit/s. In particular it has been designed to excel in the bi-directional processing of 4K UHD (12G SDI) I/O signals, allowing the user to employ new 4K UHD equipment into an existing HD or 3G infrastructure. An LED illuminates to indicate when input is present. This module does not support SQD nor Square Division quad conversions.
