GENERAL INFORM ATION The Telex Model USR-100 Receiver and associated Transmitters is a 100 Channel, frequency-selectable full diversity system operating within the frequency range of 668.
Posi Phase Diversity The USR-100 receiver utilizes Telex’s patented Posi Phase auto diversity circuit. Unlike other types of diversity which receive with only one antenna at a time, Posi Phase utilizes both antennas at all times. This results in a stronger signal from the microphone for cleaner audio and greater range.
Displays The 7 Segment LED channel display already mentioned (00 to 99). 2. A 5 segment LED light array for AF, that aids in setting micro - phone gains and monitoring receiver microphone and line level outputs. Light numbers 4 and 5 have a Peak Hold feature.

Figure 1 Front Panel Power Switch: When turned on, the channel display illuminates and one of the diversity lights will come on. Channel Select Buttons: Push once to increase display by one. Push and hold to increase display more than one. Left button changes “10’s”, Right button changes “1’s”.
Figure 2 Rear Panel Antenna Jacks: Two antenna jacks for posi phase diversity recep - tion. Attach an antenna to each jack. Audio Output: XLR type jack connects to audio sound system (Amplifier/Mixer). Pin 1 ground, Pin 2 +, Pin 3 -. Audio Adjust: Screwdriver adjustable potentiometer, controls audio output.
Receiver Set-up Connect the supplied AC power adapter to an AC outlet supplying 105 to 125 volts AC, 60 Hz. The 230 volt export model should connect to an AC outlet supplying 210-240 VAC, 50-60 Hz.

SH-100 Power Switch: Located on the bottom of the handle. Battery Test Button: Press to check the remaining life of the batteries. Battery Meter: The number of segments that light when the Battery Test Button is pushed indicate the approximate time of battery life remaining.
Figure 5 LT-100 LT-100 Power Switch: Located on the top of the case. Battery Test Button: Press to check the remaining life of the batteries. Battery Meter: The number of segments that light when the Battery Test Button is pushed indicate the approximate time of battery life remaining.
Channel Select Switches: Control the transmit channel. Must be set to match the channel of the receiver. Microphone Gain: Controls the gain of the audio circuit to prevent under or over modulation. Transmit Power Switch: Set to high for maximum range.
System Set-Up NOTE: Whe employing two or more wireless microphones, the transmitters should be a minimum of 10-15 feet away from the receiver(s) to prevent “front-end” overload. Turn on the receiver. Set the Channel to the number desired on both the transmitter and receiver.
Remote mounting antennas will increase the effective reception range when appropriately positioned. The two 1/4 wave antennas supplied are not ground independent and therefore not appropriate for remote mounting. See the accessories section of this manual for remote- mountable antenna options.
Figure 7 Antenna Placement with Accessory Brackets and Cables If possible, do not mount the brackets on a wall. See Figure 7 for bracket and antenna placement. Antenna Connection Attach the two antenna cables to the back of the USR-100. Be sure the connectors are tightened securely.
Installing Rack Mounts The USR-100 is supplied with rack mounts for both double and single mounting in a 19" equipment rack. For single mounting, the long and short rack “ears” are used. For dual mounting, use the short “ears and the mid brackets from two USR-100’s.
Double Mounting: Align the mid brackets (Item No. 2) with the holes on the adjacent sides of each unit. Install the previously removed screws. Insert an additional screw (Item No. 4 provided in the parts pack) into the remaining holes. Tighten all screws securely.
