Page 2: Introduction
Installation Note: READ THIS BOOK! The Liberator One System has been designed for easy installation by persons with minimal electronic experience, although some technical knowledge will be helpful. Ultimate system performance depends on proper antenna placement and installation, so pay close attention to the antenna placement guidelines.
Page 3: System Features
Unlike other wireless microphones, your Liberator One does not have to be returned to the factory for new crystals and re-tuning if an alternate frequency is needed.
Page 4: The Transmitter
TRANSMITTER CONTROLS AND FEATURES The WMS T11 Transmitter is compact and easy to operate. The microphone plugs into the MIC jack. If a rechargeable 9V battery is used, the charger also plugs into the MIC jack to charge the battery. Transmitter Control Switch The Transmitter has a single control switch on top of the unit.
Page 5: Microphone Connector Lock
Microphone Connector Lock The Connector Lock can be added to the microphone plug to prevent the microphone plug from accidentally coming out during use. The connector locking pin attaches to the mic plug and fits into the oval hole next to the MIC jack when the back cover of the transmitter is opened. To attach the Connector Lock, unscrew the plug shell and slip on the locking clip as shown.
Page 6: Transmitter Battery Information
TRANSMITTER BATTERY INFORMATION Battery Installation: To install the battery, lift up on the battery compartment tab. Handle the battery wires gently when attaching the battery to the snaps. Lay the battery inside the compartment, tuck in the excess wire, and snap the battery compartment shut.
Page 7 Battery Charging: There are two Chargers available for the BAT 003 Rechargeable Battery. The BAT 005 Charger plugs directly into the Transmitter MIC jack to charge the battery without removing it from the Transmitter. The BAT 004 Charger has battery snaps, allowing the battery to be snapped onto the Charger.

Page 11: Antenna Installation
Receiver Antenna Installation Liberator One There are two antenna types, depending on which system you purchased. The WMS L100 System includes the ANT 011 Whip Antenna. The WMS L150 System includes the ANT 016 Wall- Mount Dipole Antenna. The ANT 011 Whip Antenna is suitable for portable and general use.

Page 13: Front View
Dipole Antenna (ANT 016) Installation The WMS L150 Liberator One System includes the ANT 016 Dipole Antenna. Assemble the antenna as shown on the previous page. Use the Coaxial Feedline Cable included to connect the Dipole Antenna to the Antenna Connector on the rear panel of the WMS R11 Receiver.
Page 14 The Coaxial Feedline Cable may be extended up to 100 feet if necessary, with a slight loss in system range. Fifty-foot extension cables are available from Williams Sound (Part Number WCA 008 50). If you supply your own extension cable, use RG59 coax with at least 90%...

Page 17: Using The Liberator One System
Using the Liberator One System: (1) Install the battery in the Transmitter and plug in the MIcrophone as shown on page 5. (2) Make sure the sound system is turned OFF. Place the Liberator One WMS R11 Receiver near the sound system amplifier or mixer.

Page 19: Using Multiple Systems
Using Multiple Systems: It is possible to operate up to 10 Liberator One Systems in the same place at the same time if each is set to a different (non-adjacent) operating frequency. DO NOT operate more than one system on the same frequency, or they will interfere with each other.
Page 20 Antenna Splitters: To simplify remote antenna installation in multiple system applications, we offer a 1:2 Antenna Splitter Kit (ANT 009) and a 1:4 Antenna Splitter Kit (ANT 010), which allow more than one WMS R11 Receiver to share an antenna. These are not necessary if the ANT 011 Whip Antennas are used.

Changing the WMS R11 Receiver Frequency: (1) Make sure the Receiver is unplugged from AC power. (2) Use a 5/64" hex screwdriver to loosen the four screws on the side of the Receiver case. Lift off the top cover. (3) Locate the two frequency-programming switches, S2 and S3, as shown on the diagram above.
