Crestron SRD-AMP-1 High Gain Line Amplifier
High Gain Line
Amplifier: SRD-AMP-1
Introduction
The SRD-AMP-1 is an inline amplifier intended for use in overcoming
cable and splitter losses in a Crestron
®
XM or SIRIUS
®
satellite radio
distribution network. It is rated to provide 16 dB (typical) of gain in the
satellite radio band (2320-2345 MHz), and is powered from the DC bias
voltage (4.5 VDC to 6.5 VDC nominal) provided by the antenna
connection on the satellite radio tuner downstream. It is also designed to
pass DC voltage to provide power to the antenna and other line amplifiers
installed upstream.
Placed at the beginning of a cable run, a single SRD-AMP-1 line
amplifier will overcome the loss of approximately 150 feet of standard
RG-6 cable. Up to two amplifiers may be cascaded at one spot for a total
of 32 dB of gain to overcome the loss of 300 feet of cable. Cable runs in
excess of 350 feet are possible using quad shielded RG-6, with additional
SRD-AMP-1 line amplifiers installed inline as necessary, spaced equally
along the cable run to prevent overload and distribute the gain properly.
An F-male coupler is included for use in connecting two line amplifiers
in cascade.
The amplifier will pass DC power in both directions, but must be
installed so the output (marked with an arrow labeled RADIO) is always
oriented in the direction of the radio.
NOTE: The SRD-AMP-1 is designed for indoor or outdoor mounting.
