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.

Industry Compliance
As of the date of manufacture, the SRD-AMP-1 has been tested and
found to comply with specifications for CE marking and standards per
EMC and Radiocommunications Compliance Labelling.
Installation
Refer to the illustrations on page 2, and, using the screws provided, orient
and mount the amplifier(s) appropriately according to the distance
between the antenna and the radio. Prepare and connect appropriate RG-6
and/or RG-6 (quad shield) cables to the amplifier(s).
NOTE: For best results in all configurations, use quad-shielded RG-6
cable whenever possible.

Problem Solving
Troubleshooting
The table after this paragraph provides corrective action for possible
trouble situations. If further assistance is required, please contact a
Crestron customer service representative.
SRD-AMP-1 Installation Troubleshooting
TROUBLE POSSIBLE
CAUSES
CORRECTIVE ACTION
With radio on and all
antenna cables
connected at the radio,
check for 4 - 7 VDC at
antenna end of cable.
No signal
reception. Radio
display shows:
“Antenna
Disconnected”, or
“Acquiring Signal”
Short circuits
or
discontinuities
With radio on and all
antenna cables
connected at the radio,
check for AC voltage at
antenna end of cable;
should be < 1 VAC. If AC
voltage is found, check
for ground loops.
Ensure proper cable type
and length(s) per the
illustrations on page 2.
Antenna is
connected
properly but
signal is too
weak for
reception.
Ensure amplifiers are
oriented properly with the
output (marked with an
arrow labeled Radio)
oriented towards the
radio.
“Check Antenna”
or “No Signal”
Refer to the instructions
supplied with the antenna
to ensure the antenna is
pointed accurately.
