AD-4 Audio Distribution System

Quick Overview

Let the music move you with the AD-4 audio distribution system from RTI. Go to the exercise room to summon your iPod®, listen to broadcast radio in the kitchen, internet radio in the backyard, and a CD in the living room - all at the same time. With four analog audio source inputs and outputs, wherever you go - the music moves with you. An integrated 8-channel amplifier provides plenty of power, while zone independent volume and tone control brings the sound to life. When you combine the AD-4 with RTI central processors, remote controls, touchpanels, and keypads, this RTI distributed audio solution easily keeps pace with the rhythm of your life.
