The replacement of the industry's most popular modulator,HD-1603, accepts a 4K signal and will loop-through that same signal, however modulated signal is still limited to 1080P, due to the limitations with TV tuners.

Like the HD1603, the Q4K-R1 supports Resi-linx IR targets and emitters. Resi-linx are the market leader in both IR and modulation and the only brand to have Foxtel approved product in both fields.

This unit has full menu via LCD display, improved MER resulting in higher quality picture and is configurable for New Zealand. Q4K-R1 allows you to distribute any HD source around your home/business installation over coax cable and control with ease.
