Zektor?s exclusive IIR? (Intelligent Infra Red) learning allows the HDS4.1 to work with nearly any remote control you already own. Or add one of our ZRM1 remotes to your order. All discrete codes can be learned using Zektor's IIR?, for easy macro programming of universal remote controls.

Since Zektor's IIR? allows you to use any remote, you don't need to order a remote if you plan on using your own remote to operate the HDS4.1.

The HDS4.1 uses High Quality Gold Clad, Silver-Palladium Relays to switch all analog signals, for noise free, distortion free operations.
