The Techly IDATA SPDIF-4 accepts an HDMI input and outputs a composite analog video signal plus uncompressed stereo L/R audio through three RCA connectors. This lets users connect modern HDMI sources — set-top boxes, Blu-ray players, game consoles — to traditional televisions or projectors that use composite (CVBS) video and RCA audio inputs.

Installation requires no configuration: connect an HDMI cable from the source, a three-RCA cable to the display or projector, and the included DC 5V power supply. Supported composite output is NTSC/480i or PAL/576i. If the destination device lacks a matching input, a separate RCA-to-SCART converter can be used.
