AD-4

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. Imagine every

aspect of your environment working in complete

harmony – from audio and video to lighting,

ambience, temperature and more. 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.
