Wire-Lists #45 – Three Easy Steps to Setting Compatibility Modes and IR Sync in Lectrosonics Receivers

Social Media WireLists45 300pxWe recently received a few calls in Service from users confused about the IR-Sync function with our receivers, so we put together this list as both a refresher and a guide.

  1. Select your Frequency Step size on your receiver by navigating to Step Size and selecting either 100 kHz or 25 kHz to match the transmitter you are using. 25 kHz is now the standard for Lectrosonics systems, with the exception of the IFBR1A, which is 100 kHz and does not have an IR Sync function. Adjustments of 25 kHz increments between the two may be needed for other manufacturers or when frequency coordination requires it. The step size must match on both your transmitter and your receiver.

Select your receiver Compatibility Mode. Navigate to Compat Mode, using the Up and Down arrows to scroll through the choices. When the desired mode appears in the screen, press MENU/ SEL or BACK to select the mode and return to the previous menu. Press BACK to return to the Main Window.

    A Note on Compatibility Modes

If you are using a receiver and a transmitter with the options of NU Hybrid and NA Hybrid, make sure that your transmitter and receiver are set to the same Hybrid Compat Mode. Otherwise, you will get a COMPAT ERROR message and you will be unable to sync.

    The below is a chart for your general reference. Please note that not all Lectrosonics receivers have all modes:


  3. Navigate to Smart Tune in the LCD menu and press MENU/SEL to start the process of finding a clear frequency. Select the desired range to be scanned, then press MENU/SEL to start the scan. 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. IR Sync will prompt you to place the receiver and transmitter close to one another and press the UP arrow button. Hold the units within a foot or so apart with the IR ports facing each other, then press the button. Please note that if you are outdoors and/or in a sunny area, you may need to hold your units a closer, and possibly shade them from direct sunlight, to get them to “see” each other. The transmitter LCD will display a message confirming the receipt of the settings.

Setting up Encryption may be a concern for some of you, though it is not essential when performing a basic IR Sync. We will address the modes of Encryption in a future Wire List.
