RTI AD-4 

Distributed Audio System

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.

Description

The AD-4 is perfect for residential or commercial installations that require music everywhere - without breaking the budget. This compact audio distribution system contains both a matrix switching pre-amp and a built-in power amplifier. The four local source inputs can be augmented with four remote source inputs, making it easy to listen to music from your bedroom CD player, iPod® dock, or PC. A single Cat-5 cable connects the remote source’s audio and infrared signals between the remote location and the AD-4.

The AD-4 audio distribution system is designed to be a seamless extension of an RTI control system. The AD-4 provides the audio switching, amplification and distribution functions, while RTI central processors and user interfaces manage the audio source control, user input and status feedback. Information such as the selected source, volume level, and tone control settings are available for each zone. Depending on the source equipment used, more advanced information such as song playlists, cover art, and tuner RDS data may also be available.

Of course with RTI control systems, audio is just the beginning. Imagine every aspect of your environment working in complete harmony – from audio and video, to lighting, ambience, temperature and more. Such scenarios are only made possible from an audio distribution system backed by a real, professional grade control system. Thanks to the efficient engineering that defines the AD-4, there is no reason to limit yourself to a system that was designed only for music – with RTI so much more is possible.
