The Extron FOX AEX 108 Eight Port Fiber Optic Audio Extractor enables independent processing and routing of audio signals in a fiber optic AV distribution system. Each port accepts signals from a FOX Series transmitter, extracts the two‑channel audio signal to provide a balanced or unbalanced analog stereo output, and retransmits the original signal to a FOX Series receiver. Output reclocking on the buffered pass‑through maintains signal integrity, transmitting the fiber optic signal at original power levels. Featuring high‑speed, all‑digital signal transmission of pixel‑perfect video, audio, and control signals over fiber optic cabling, the FOX AEX 108 is compatible with FOX Series HDMI, DVI Plus, DVI, VGA, VGA/YUV, and AV transmitters and receivers.

As part of the extensive FOX Series of fiber optic products from Extron, the FOX AEX 108 is also compatible with a wide range of FOXBOX and other FOX Series products. It can be used in combination with select FOXBOX and PowerCage FOX extenders and FOX Series distribution amplifiers, switchers, and matrix switchers for support of enterprise-wide installations.

This fiber optic audio extractor is available in multimode and singlemode models. The FOX AEX 108 MM supports multimode fiber at 850 nm, which is typically used within buildings or facilities with moderate-range transmission distances. The FOX AEX 108 SM supports singlemode and multimode fiber at 1310 nm. Singlemode fiber offers long range transmission capability over extreme distances of up to 30 km (18.75 miles). It is used in very large facilities such as airports, shopping centers, and stadiums, as well as providing connection between facilities such as for university campuses. Because transmission of content is inherently secure and immune to outside interference, fiber applications are also preferred in government, military, and medical environments.

The FOX AEX 108 is ideal for use in FOX Matrix system applications that require extraction of audio signals for local independent distribution and processing within an equipment room. It can be used to extract audio signals from remote AV sources for independent routing before sending the fiber optic signal through a FOX Matrix switcher. In this configuration, the FOX AEX 108 receives signals from an AV source via a FOX Series transmitter, extracts the audio, and transmits the original fiber optic signal to an input on the matrix switcher. The line-level balanced or unbalanced analog stereo audio is made available to the audio processing and distribution system.

When used on the output side of a FOX Matrix switcher, the FOX AEX 108 extracts program audio for independent processing through a mixer, DSP, or audio amplifier before transmitting the fiber optic signals to remote displays. In this configuration, the FOX AEX 108 receives output signals from the matrix switcher, extracts the audio, and transmits the original fiber optic signal to a remote display. A FOX Series receiver at the remote display converts the optical signal to video, audio, and control.


Note: The FOX AEX 108 is not compatible with the FOX 3G HD-SDI extender or the FOX 3G DVC signal converter.
