LectroRM
By New Endian LLC
LectroRM is a mobile application for iOS and Android 
operating systems to remotely control Lectrosonics 
Transmitters.
The app remotely changes settings on the transmit-
ter through the use of encoded audio tones, which 
when received by the attached microphone, will alter 
the configured setting. The app was released by New 
Endian, LLC in September 2011. The app is available 
for download and sells for about $20 on the Apple App 
Store and Google Play Store.
LectroRM’s remote control mechanism is the use of 
an audio sequence of tones (dweedles) that are inter-
preted by the transmitter as a configuration change. The 
settings available in LectroRM are:
•  Audio Level (Gain)
• Frequency
•  Sleep Mode
•  Lock Mode
•  Output Power
•  Low Frequency Roll-off
•  LED on/off
User Interface
The user interface involves selecting the audio se-
quence related to the desired change. Each version has 
an interface for selecting the desired setting and the 
desired option for that setting. Each version also has a 
mechanism to prevent accidental activation of the tone.
iOS
The iPhone version keeps each available setting on a 
separate page with the list of options for that setting. 
On iOS, the “Activate” toggle switch must be enabled to 
show the button which will then activate the audio. The 
iOS version’s default orientation is upside-down but can 
be configured to orient right-side up. The purpose for 
this is to orient the device’s speaker, which is at the bot-
tom of the device, closer to the transmitter microphone.
Android
The Android version keeps all settings on the same 
page and allows the user to toggle between the activa-
tion buttons for each setting. The activation button must 
be long pressed to activate. The Android version also 
allows users to keep a configurable list of full sets of 
settings. 
Activation
For a transmitter to respond to remote control audio 
tones, the transmitter must meet certain requirements:
•  The transmitter must not be turned off; it can how-
ever be in sleep mode.
•  The transmitter must have a later firmware version 
that enables remote control. 
•  Remote control must be enable on the transmitter.
