Moseley SL9003Q 602-12016-01 Revision J
1. System Features & Specifications
1.1 System Introduction
The Moseley STARLINK 9000 is the first all-digital, open-architecture, modular system for
CD-quality audio transmission. The versatility and power of the STARLINK 9000 comes from
a complete range of plug-and-play personality modules.
The SL9003Q Digital Studio-Transmitter Link (DSTL) provides a transmitter/receiver pair
that conveys high quality digital audio across a microwave radio path. Typically, program
material is transmitted from a studio site to a remote transmitter site, to a repeater site, or
in an intercity relay application.
Utilizing spectrally efficient digital Quadrature Amplitude Modulation (QAM) technology, the
SL9003Q delivers four discrete 16/24-bit linear audio channels with RS-232 data over
standard FCC Part 74 (950 MHz) STL frequency allocations.
As a discrete STL, the AES/EBU digital audio I/O, combined with a built-in variable sample
rate converter, provide seamless connection to the all-digital air chain without compression.
The system has provisions for asynchronous auxiliary data channels (up to 38,400 baud)
that are used for communication in remote control applications. Plug-in MPEG audio
modules and a digital multiplexer support additional program, voice, FSK, async and sync
data channels.
The high spectral efficiency of the SL9003Q is achieved by user-selectable 16, 32, 64 or 128
QAM. Powerful Reed-Solomon error correction with interleaving, coupled with 20-tap
adaptive equalization, provide unsurpassed error-free signal robustness in hostile RF
environments for which there is no comparable benefit in analog transmission.
1.2 System Features
In addition to establishing a new industry standard for studio-transmitter link performance,
the SL9003Q incorporates many new and innovative features:
•Linear 16/24-bit digital audio performance.
•Higher system gain, 26 dB more than analog composite STL.
•Degradation-free multiple hops.
•Configurable for up to 4 linear audio program channels per STL system.
•No crosstalk between channels.
•No background chatter from co-channel or adjacent-channel interference.
•Built-in AES/EBU digital audio interface.
•Operation through fractional T1 networks.
•Built-in data channels alleviate the need for FM subcarrier data channels.
•Extensive LCD screen status monitoring.
•Peak-reading LED bar graph display for all audio channels.

1.4 Regulatory Notices
FCC Part 15 Notice
Note: This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference, in which
case the user will be required to correct the interference at his own
expense.
Any external data or audio connection to this equipment must use
shielded cables.
FCC Part 74 Equipment Authorization
The SL9003Q Transmitter has been granted Equipment Authorization
under Part 74 of the FCC Rules and Regulations.
Equipment Class: Broadcast Transmitter Base Station
Frequency Range: 944-952 MHz
Emission Bandwidth: 200 – 500 kHz
FCC Identifier: CSU9WKSL9003Q74

Be sure to retain the original boxes and packing material in case of return shipping. Inspect
all items for damage and/or loose parts. Contact the shipping company immediately if
anything appears damaged. If any of the listed parts are missing, call the distributor or
Moseley immediately to resolve the problem.
2.2 Notices
CAUTION
DO NOT OPERATE UNITS WITHOUT AN ANTENNA, ATTENUATOR, OR LOAD
CONNECTED TO THE ANTENNA PORT. DAMAGE MAY OCCUR TO THE
TRANSMITTER DUE TO EXCESSIVE REFLECTED RF ENERGY.
ALWAYS ATTENUATE THE SIGNAL INTO THE RECEIVER ANTENNA PORT TO
LESS THAN –37 dBm (3000 uV). THIS WILL PREVENT OVERLOAD AND
POSSIBLE DAMAGE TO THE RECEIVER MODULE.
DO NOT ATTEMPT TO ADJUST TRANSMITTER POWER. THIS WILL CAUSE THE
LINK TO FAIL TO OPERATE.
AVOID EXCESSIVE PRESSURE ON THE AUDIO ADJUSTMENT
POTENTIOMETERS LOCATED ON THE BACK PANELS OF THE AUDIO
ENCODER/DECODER MODULES.

WARNING
HIGH VOLTAGE IS PRESENT INSIDE THE POWER SUPPLY MODULE
WHEN THE UNIT IS PLUGGED IN. REMOVAL OF THE POWER
SUPPLY CAGE WILL EXPOSE THIS POTENTIAL TO SERVICE
PERSONNEL.
TO PREVENT ELECTRICAL SHOCK, UNPLUG THE POWER CABLE
BEFORE SERVICING.
UNIT SHOULD BE SERVICED BY QUALIFIED PERSONNEL ONLY.
PRE-INSTALLATION NOTES
•Always pre-test the system on the bench in its intended configuration prior to
installation at a remote site.
•Avoid cable interconnection length in excess of 1 meter in strong RF environments.
•Do not allow the audio level to light the red “clip” LED on the front panel bar graph, as
this causes severe distortion (digital audio overload).
•We highly recommend installation of lightning protectors to prevent line surges from
damaging expensive components.
2.3 Rack Mount
The SL9003Q is normally rack-mounted in a standard 19-inch cabinet. Leave space clear
above (or below) the unit for proper air ventilation of the card cage. The rack ears are
typically mounted as shown in Figure 2-1. Other mounting methods are possible, as outlined
in Section 3, Installation.
