PORTABLE WIRELESS SOUND SYSTEM OPERATING INSTRUCTIONS and trouble-shooting guide LECTROSONICS, INC.
INTRODUCTION Thank you for selecting the LONG RANGER II Portable Wireless Sound System. This system represents over 80 years of combined experience in the design of RF transmitters, receivers and Public Address systems. The LONG RANGER II sets new standards for operational convenience, flexibility and mechanical ruggedness. The built-in wireless receiver, the rechargeable power supply and the high audio output set this system apart from any other portable PA system on the market.
GENERAL TECHNICAL DESCRIPTION The standard LONG RANGER II Portable Wireless Sound System consists of a combination wireless receiver/amplifier/speaker with a rechargeable battery pack, an M170 belt-pack transmitter and a microphone. Optional microphones, extension speakers and add-on equipment for a second wireless channel are available. These items will be discussed elsewhere in this manual.
CONTROLS AND FUNCTIONS CONTROL PANEL WIRELESS MICROPHONE VOLUME Turns unit power on and off and also functions as the volume control for the internal wireless receiver. POWER A red LED that lights when unit power is on. RF A green LED that lights when the companion transmitter is turned on and there is sufficient signal for good system operation. Internal circuits monitor both signal level and interference levels and decide if the transmitted signal is strong and "clean" enough for satisfactory operation.
FRONT PANEL 12V DC POWER INPUT A special jack used to connect an external 12 Volt DC source to the unit to substitute for the "on-board" battery pack. It is most commonly used for connecting the LONG RANGER II to a vehicle cigarette lighter receptacle. When an external power source is connected to this jack, the on-board battery pack is automatically disconnected.
M170 SERIES TRANSMITTERS Standard LONG RANGER II systems include an M170 belt-pack transmitter which is designed to be used with a lavalier or headset microphone. The optional M170-XLR transmitter is similar to the M170 but is equipped with two microphone connectors; a locking micro jack for lavalier or headset microphones and an XLR connector for use with standard low impedance hand held microphones.
SYSTEM SETUP RULES This section includes some basic rules that will ensure trouble-free operation of your LONG RANGER II system: 1) Make sure the transmitter battery is good, or better yet, new. 2) Charge up the battery pack in the LONG RANGER II fully before you use the system. Charge until the green charging lamp underneath the CH-40 jack on the LONG RANGER II control panel goes out. 3) Set up the system so that the LONG RANGER II is as far from large metal surfaces as possible.
INITIAL EQUIPMENT ADJUSTMENTS This section covers the initial adjustments to the transmitter and LONG RANGER II that must be made before the system is placed into operation. The step-by-step procedures are listed in the order in which they should be performed: 1) Turn LONG RANGER II power on - The POWER lamp lights. 2) Rotate both volume controls counter-clockwise to their minimum settings.
) You may now adjust the WIRELESS MICROPHONE VOLUME control on the control panel to a level where everyone can hear. You will probably have to do this in several steps. If you attempt to adjust the volume yourself while standing and transmitting just behind the unit, you will likely have a "feedback" problem. It is convenient to have another person adjust the volume while you transmit from a position 20 feet or more behind the unit.
ADDING A SECOND WIRELESS CHANNEL TO YOUR LONG RANGER II A very popular feature of the LONG RANGER II is the ability to add a second wireless channel to an existing system in the field. The Lectrosonics 170 MINI-LR system was expressly designed for that purpose. The standard system consists of a SR170-LR receiver, an M170 transmitter and a microphone. Options include the M170-XLR transmitter and a number of other microphones.
3) The SR170-LR receiver is to be mounted on the LONG RANGER II upright with velcro. The receiver should be positioned, control panel up, between the horn mounting screw and the screw which secures the battery pack to the upright. Remove the paper backing from one side of the velcro and affix it to the back of the receiver. Remove the remaining paper backing and affix the receiver to the upright. 4) Connect the antenna plug to the BNC connector on the SR170-LR receiver.
MULTIPLE LONG RANGER II SYSTEMS A unique use of the AUX IN/OUT jack is for connecting two (or more) LONG RANGER II systems together for simultaneous use. When the LONG RANGER IIs are interconnected in this manner, they will operate like a single system. You will have two (or more) wireless microphone inputs, two hardwired mic inputs and much more audience coverage. The sound from all the LONG RANGER IIs will be the same.
MICROPHONE CHOICES M119 - This is a very small, omni-directional mic used only as a lavalier ("lapel") microphone. It may be prone to feedback since it is usually placed so far away from the users mouth; however it has a very flat response and excellent tone quality. The M119 generally works best with the LONG RANGER II and an ES300 column speaker indoors at a lower volume setting. As is true of most omni-directional type microphones, the M119 is very free from wind noise and clothing "rattle".
