Four-Way Amplified Splitter: SRD-SPL-4

Introduction

The SRD-SPL-4 is a high quality amplified splitter optimized to split a single antenna signal to feed up to four satellite radio tuners as part of a Crestron ^® XM or SIRIUS ^® satellite radio distribution network. Its built-in line amplifier is rated to provide 8 dB (minimum) 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 connections on any of the satellite radio tuners downstream. It is also designed to pass DC voltage to provide power to the antenna and other line amplifiers installed upstream.

Accessories furnished with the SRD-SPL-4 include four 3-foot F (female)-to-SMB (male) adapter cables, four F (male)-to-F (male) couplers, and one SMB (female)-to-F (male) adapter. Standard RG-6 cable with male F connectors (not supplied) may be used to extend the output cable length up to 70 feet from each individual output to each satellite radio tuner. Adding an SRD-AMP-1 line amplifier (sold separately) at the input of the splitter will enable longer output cable lengths of up to 200 feet each.

NOTE: Unused outputs do not have to be terminated for proper operation.

A 20 dB power passing attenuator is also included for use in preventing overload of the splitter input in any installation that is located near a high power satellite radio terrestrial repeater.

NOTE: The SRD-SPL-4 is designed for indoor or outdoor mounting.

Industry Compliance

As of the date of manufacture, the SRD-SPL-4 has been tested and found to comply with specifications for CE marking and standards per EMC and Radiocommunications Compliance Labelling.

Installation

Installation of the SRD-SPL-4 splitter consists of the following. Refer also to the “Block Diagram” on page 2.

• Attach the RG-6 cable from the antenna to the port labeled IN on the splitter.
• Attach RG-6 cables (up to 70 ft) to the splitter OUT ports and route them to the radios. Use the four supplied 3-foot cables to adapt the F-male connector on the RG-6 cables to the SMB-jacks on the radios.

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-SPL-4 Installation Troubleshooting

TROUBLE	POSSIBLE CAUSES	CORRECTIVE ACTION
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 4 - 7 VDC at antenna end of cable.
		With radios on and all antenna cables connected at the radios, check for AC voltage at antenna end of cable; should be < 1 VAC. If AC voltage is found, check for ground loops.
“Check Antenna” or “No Signal”	Antenna is connected properly but signal is too weak for reception.	Ensure proper cable type and length(s) per the block diagram on page 2.
		Ensure any amplifiers are oriented properly with the output (marked with an arrow labeled Radio) oriented towards the radio.
		Refer to the instructions supplied with the antenna to ensure the antenna is pointed accurately.
Limited reception or channels available for XM and/or SIRIUS tuners.	Problem with tuner card.	Ensure that the tuner card is registered/activated.
