About the Crestron AUD-EXT-100
The AUD-EXT-100 transports an unbalanced (RCA) stereo analogue audio signal over CAT5 or greater UTP cable, sold separately, for up to 2000 ft. It works as a transmitter and companion receiver, both completely passive, so no extra cables or power supplies are needed. Each part fixes to a flat surface or to a single rack rail at the back of an equipment rack, and up to three units can share a standard 1U 19-inch rack shelf side by side.
In a Sonnex multiroom audio system, AUD-EXT extenders provide audio return channels. With an audio return channel, a source in one room of the house can be sent to any other room through the central audio distribution system. Each AUD-EXT-100 carries one unbalanced stereo signal, so plan one unit per return channel.

Questions about the Crestron AUD-EXT-100
What does the Crestron AUD-EXT-100 do?
It extends one unbalanced stereo analogue audio signal, from RCA connections, over CAT5 or greater UTP cable for distances up to 2000 ft. It works as a transmitter and companion receiver and is completely passive, so no power supplies are needed.
Does the AUD-EXT-100 need power?
No. AUD-EXT devices are fully passive, so neither the transmitter nor the receiver needs a power supply or any extra cables. You only need the CAT5 or greater UTP cable between them, which is sold separately.
How is the AUD-EXT-100 used with Sonnex multiroom audio?
Crestron designed its audio over CAT5 extenders to provide audio return channels in Sonnex multiroom audio systems. An audio return channel lets a source in one room of the house reach any other room through the central audio distribution system.
How far can the signal be extended?
Crestron states that the AUD-EXT-100 extends signals up to 2000 ft using CAT5 cable, which is sold separately. The cable should be CAT5 or greater UTP. Each unit carries one unbalanced stereo signal, so a system returning several sources needs one extender per signal.
How is the extender mounted?
The transmitter and the receiver can each be fixed to a flat surface or to a single rack rail at the back of an equipment rack. Alternatively, up to three units fit side by side on a standard 1U 19-inch rack shelf.
How much is the Crestron AUD-EXT-100?
Crestron asks its dealers to give the price of the AUD-EXT-100 directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the AUD-EXT-100?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the AUD-EXT-100 on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the AUD-EXT-100 come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the AUD-EXT-100 develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the AUD-EXT-100 in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.

Yes. We supply Crestron to end users, with or without installation. If you are not sure it suits your system, send us the part numbers you already have and we will check.
