2R Two channel RCA to CAT-5 exender
• Stereo audio ‘baluns’ for RCA inputs using CAT-5/6 cable
• Lets you run cables to 100 meters (350’) without loss
• Ruler-at frequency response from 5 Hz to 20 kHz
• Superior noise rejection from ground loops & magnetic elds
The Iso•Max CI-RJ2R is a two channel input isolator that lets you extend
unbalanced signals to 100 meters (350’) using standard CAT-5 or CAT-6 bal-
anced twisted pair Ethernet cable.
Sold as a ‘transmit and receive’ set, the design begins with two rugged
anged steel enclosures for easy mounting under a desk or inside a rack or
NEMA enclosure. Each end is equipped with RCA inputs and outputs with
a standard Ethernet RJ45 type connector in between. One merely connects
the source and destination devices using the RCAs and bridges the two
units using o the shelf CAT-5 or CAT-6 cable. This enables the system de-
signer to employ pre-wired network cable to run analog audio throughout a
facility without having to sh new wires.
Plug and play easy to use, this passive interface does not require any
power to work. Inside the receive module are two Jensen high performance
transformers that are able to withstand signal levels to +19 dBv at 20 Hz
without any discernible distortion. These provide galvanic isolation between
the input and output to eliminate hum and buzz caused by ground loops,
rejecting noise by as much as 124 dB. Once installed, the CI-RJ2R will quietly
go to work without introducing distortion, phase shift or artifact of any kind.

Connecting a laptop computer
The CI-RJ2R makes it easy for presenters to play audio tracks from
their computer to a PA system. Connect the audio output from
the computer to RCA inputs on the CI-RJ2R transmitter and the CI-
RJ2R receiver will deliver the audio without distortion or artifact.
Connecting a CD player
Certain installations require connecting unbalanced consumer
audio devices that may be distanced apart. The CI-RJ2R lets you
use pre-existing CAT-5 network cable in between the transmit
and receive modules and send the signal up to 100 meters (350’)
without noise.
