Congratulations on your purchase of the Digital Audio Extender. Your complete
satisfaction is very important to us.

on solutions that harness integration, extension, distribution, and conversion
technologies. Gefen’s reliable, plug-and-play products supplement cross-platform

The Gefen Digital Audio Extender
Place your digital audio components anywhere you want with Gefen’s Digital
Audio Extender. It supports either S/PDIF or TOSLINK digital audio signals, which
are commonly used to transmit stereo and multichannel digital audio like Dolby®
Digital and DTS®. The Digital Audio Extender uses a Sender and Receiver system
connected by a CAT-5e cable to extend the digital audio up to a 330 feet (100
meters).
How It Works
The Digital Audio Extender’s Sender unit connects to the audio source
component. The Digital Audio Extender’s Receiver unit connects to the extended
audio component (up to 330 feet away). One CAT-5e cable connects the Sender to
the Receiver unit.

Industry standard Category-5 (CAT-5 or CAT-5e) cables are used to link the Digital
Audio Extender Sender and Receiver units together.

more than 330 feet (100 meters) in length.

CONNECTING THE DIGITAL AUDIO EXTENDER
How to Connect the Digital Audio Extender System:
1- Connect your digital audio source’s outputs to the Sender unit’s digital input using
either the TOSLINK or the S/PDIF input. Please see “Panel Layout” on page 4
for a list of connectors on the units.
2- Connect the Sender and Receiver units to one another on their RJ45 link
connector jacks using a single CAT-5 cable.
3- Connect the digital output of the Receiver unit to the digital input of the amplier/
speaker system using either the TOSLINK or the S/PDIF connection. The digital
audio will be present on both the TOSLINK and S/PDIF output regardless of which
digital input is used on the Sender unit.
4- Power on your audio sources and audio playback system. Plug the included
5 Volt DC power supply into the Sender unit. Observe that the red LED on the
Receiver unit lights up. If it does not, examine all connections carefully and try
again. Upon successful powered connection of the Sender and Receiver units, you
will hear pristine digital audio on your digital audio playback equipment connected to
the Receiver unit.
Please refer to the next page (page 4) for a detailed panel layout showing
all connectors on the sender and receiver units.
