The Hi-Fi 4x4 is a compact and powerful four source, four zone distributed audio system that utilizes built-in speakers for a truly sleek installation. With a free iOS app for selecting music and controlling volume, plus optional Bluetooth connectivity (utilizing part number 95A04-2), the revolutionary Hi-Fi 4x4 lets you share streaming or stored music from devices you already own. Installation is simple, with volume source controls and remote input modules connected via Cat5e cable, homerun to the distribution/amplification module that can mount in a Leviton Structured Media Center. The Hi-Fi 4x4 can also be incorporated into a larger Leviton automation system, facilitating music coordination based on time or activity. For instance, automatically turn off all audio zones at bedtime, or awake each morning to your favorite station.
