DA1957CT
1-In, 4-Out Twisted Pair Distribution 
Amplifier
The DA1957CT is a 1-In, 4-Out Twisted Pair
distribution amplifier designed to connect a single 
ALTINEX Twisted Pair transmitter to as many as 4
ALTINEX Twisted Pair receivers. The DA1957CT
will pass computer video and audio signals from 
the transmitter over Twisted Pair-type (CAT-5) 
cable.
A typical setup allows a single computer's video 
and audio sources to be connected to as many as
4 Twisted Pair receivers. In turn, each receiver 
connects to a video monitor, projector etc. and/or 
an audio device such as a speaker or amplifier.
ALTINEX compatible transmitters and receivers 
include the DA1930CT Video+Audio Twisted Pair
Transmitter and the DA1931CT Video+Audio
Twisted Pair Receiver.
The DA1957CT is capable of equalizing the 
attenuation effects of very long cable runs
depending upon the type and quality of cable being 
used. Additionally, there is a Signal Detect feature 
which shows when an input signal is present.
The latest generation of Twisted Pair devices uses 
an innovative, patented technology* developed by 
ALTINEX. The new signal processing technology 
allows transmitting and receiving fully equalized 
computer video signals, stereo, and audio signals 
over long distances.
