Connection Diagram Overview AE02 is a set of RCA audio/ 3.5mm phone jack audio extenders designed to use a cost-effective CAT5e UTP cable to carry the signal, with the transmission distance up to 1,968 ft. Stereo Audio Extender over CAT5e for 1,968 ft Long-Distance RCA/3.5mm Stereo Audio Extension The easiest way to extend stereo audio is to have longer 3.5/RCA cables. Typical RCA/3.5mm transmission distance is between 15-20m (49-65 ft), beyond which you may need an audio extender to achieve 3.5mm/RCA audio extension. AE02 is a stereo audio extender with high flexibility. With AE02, you can transmit stereo analog audio over CAT5/5e/6 cables for 600m (1968ft) and have more options for cabling. It is ideal for installations in homes, commercial spaces, campuses, and more. Audio Extender for Stereo Speakers Noise-Free, High-Quality, and Unique Inductor Design One of the most common problems of audio extenders is the humming sound during transmission. With SC&T's unique inductor design, you can enjoy a noise-free, high-quality audio extension with AE02. We use Commscope cables for testing and recommend you choose better wires for a better listening experience. No Need for External Power Supply Typically, audio extenders require an external power supply to their transmitter, receiver, or both. AE02, by contrast, needs no external power supplies and is easy to install outdoors where power supplies are inaccessible. You are free from the problem of power supplies. A Set of Two, Transmitter & Receiver AE02 is a set of two, so you don't need to worry about the distinction between the transmitter and receiver. Only install, plug and play. Support RCA / 3.5mm for Your Different Equipment The built-in DIP switch allows you to choose between RCA and 3.5mm Phone Jack for input and output. RCA and 3.5mm jacks give you more flexibility in your choice of equipment. Eliminate Noise Caused by Ground Loops Several factors give rise to ground loops during the transmission of analog audio. To eliminate noise problems, you can try out our AE02GL Stereo Audio Ground Loop Isolator. For more about ground loop noise, read: Why Are My Speakers Buzzing?
