LR Introduction IF Amplifiers and SAW Filters Three Band Tuning Range The LR receiver tunes across a range of over 76 MHz. This tuning range covers three standard Lectrosonics frequency bands. See page 9 for more information. TUNING RANGE BAND BAND BAND Three tuning ranges are available covering standard bands as follows: Band Bands Covered Freq. (MHz) A1 470, 19, 20 470.1 - 537.5 B1 21, 22 23 537.6 - 614.3 C1 24, 25, 26 614.4 - 691.
Compact Portable Receiver SmartSquelch™ A DSP-based algorithm named SmartSquelchTM optimizes the receiver performance in very weak signal conditions. The RF level and supersonic noise in the audio are continuously monitored to determine the appropriate noise reduction needed and the point at which squelch (complete muting of the audio) is necessary.

Compact Portable Receiver Menu Item Descriptions Smart Tune An automatic scanning function that identifies a usable frequency and sets the receiver on it. After the scan is complete, an option will appear to transfer the settings to an IR enabled transmitter. The receiver will remain set on the newly discovered frequency whether or not the IR transfer option was used. Frequency Allows manual selection of the operating frequency.
LR System Setup Procedures Mode 3 is a special compatibility mode for use with another brand of wireless. Contact the factory for details. Summary of Steps 200 Series works with legacy Lectrosonics models such as all UM200, UH200 and UT200 Series transmitters. 1) Install receiver batteries and select the battery type in the setup screen. 2) Select frequency step size in the receiver. 3) Select the compatibility mode in the receiver.
Compact Portable Receiver Cursor scrolls across screen during scanning When the scan is complete a screen will appear briefly to display the frequency chosen by Smart Tune, and then it will change to IR Sync. If you are using a Lectrosonics transmitter that has an IR port, the settings can be transferred from the receiver to the transmitter in a few seconds with a single button.
LR 5) Set Up Transmitter to Matching Frequency and Compatibility Mode If you have not already set the frequency on the transmitter in the previous procedures, use IR Sync or complete the settings manually. Lectrosonics transmitters with IR Sync: On the LR receiver, navigate to IR Sync on the menu and press the MENU/SEL button. Hold the transmitter and receiver fairly close to each other (within two feet or so) and position them so the IR ports are facing one another.
Compact Portable Receiver 7) Set Receiver Audio Output Level The audio output can be adjusted from -50 dBu (mic level) to +5 dBu (line level) in 1 dB steps. It is best to use an output level high enough to drive the connected device to an optimal level without the need for additional gain. If the receiver is set to full output and the level is still not sufficient to drive the connected device to an optimal level, then some gain will need to be applied by the connected device.
LR Firmware Update As of the date of this writing, the firmware update program runs only on a Windows operating system. Updating the firmware is simply a matter of downloading a utility program and file from the web site and running the program with the receiver connected to a computer via the USB port. Go to www.lectrosonics.com/US. Click on SUPPORT in the top bar, then click on L-Series in the categories list. Click on the link labeled Firmware Updates at the bottom of the screen.
