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.
