User manual
Information on handling, operation, user interface and application scenarios.
- Putting the unit into operation
  This chapter describes the initial configuration and commissioning of the product.
- Operating instructions
  The following chapters contain additional information on operating the product.
  - Start/stop/mute recording
  - Outputting audio signals
    The receiver has two unbalanced 3.5 mm audio outputs.
  - Displays on the receiver’s display panel
    Status information such as recording mode, signal strength, battery status and audio level is shown on the display.
  - Operating the receiver
    The receiver’s display is divided into three areas for the receiver and the two transmitters. The different menu items can be opened and settings can be made using different swiping movements. The receiver is operated using the navigation principle shown below.
  - Accessing the receiver menu, navigating through menu items and making settings
    In this menu, you can make settings for the subitems Mode, Headphones, Output Level, Backup Recording, Brightness, Pairing, Rotate Display, Date, Time, Reset and Info. A complete overview of the menu can be found here: Receiver menu structure
  - Receiver menu structure
  - Accessing the transmitter menu, navigating through menu items and making settings
    In this menu, you can make settings for the subitems Recording, Mute, Gain, Low Cut, LED Lights and Memory. A complete overview of the menu can be found here: Transmitter menu structure
  - Transmitter menu structure
  - Receiver output modes
    The receiver has three different modes (mono, stereo and safety) that can be set to optimally adjust all parameters to the respective recording situation and make your work easier.
  - 32-bit float recording function
    The 32-bit float recording function enables exceptionally high dynamics, precision and the recovery of quiet and overdriven recordings on the internal memory.
  - Backup recording mode
    The backup recording mode automatically turns on the internal recording when the RF signal weakens or disappears. This feature allows you to ensure that you always have a backup audio recording on your station when needed – without having to manually start the internal recording feature at each session.
  - Adjusting the transmitter gain
    The sensitivity of the transmitter microphones can be adjusted using the gain control. It can be set on the transmitter itself, provided the transmitter is not connected to the receiver. When the transmitter is connected, this feature is disabled and controlled by the receiver.
  - Setting the transmitter low cut
    The low cut filter can reduce unwanted low-frequency noise in audio recordings.
  - Pairing the transmitter and receiver
    The two transmitters are delivered pre-paired with the receiver. If you do not automatically connect to the receiver when you turn it on, you can manually activate the pairing mode of both devices to re-establish the connection.
  - Meaning of the LEDs on the transmitter
  - Switching off the transmitter LEDs
    It is possible to turn off the transmitter LEDs individually while they are connected to the receiver. This helps prevent unwanted flashing in video recordings.
  - Rotate display feature
    The receiver has a gyro sensor that, when the "Rotate Display" feature is enabled, can automatically rotate the display by 180 degrees. This feature is especially useful if you want to shoot videos in portrait layout with your smartphone or if the display is upside down due to the attachment of the receiver to a camera or smartphone.
  - Installing updates or performing a reset
  - Attaching the transmitter to clothing
    The transmitter can be attached by clip or magnet, depending on the nature of the clothing.
  - Using the Profile Wireless as a handheld or table microphone
    Depending on the recording situation, the Profile Wireless can be used as a handheld microphone or as a table microphone on a tripod.
- Cleaning and maintenance
  Note the following information when cleaning and maintaining the product.
- Transport
  This chapter contains information on the proper transport of the Profile Wireless.

Meaning of the LEDs on the transmitter

Notice

It is possible to turn off the transmitter LEDs individually while they are connected to the receiver. This helps prevent unwanted flashing in video recordings.

Simply go to one of the transmitter menus, navigate to "LED Lights" and confirm the selection by tapping. Then tap "On" or "Off" to enable/disable this feature for the particular transmitter. (see Accessing the transmitter menu, navigating through menu items and making settings)

The transmitter LEDs automatically switch on again if the connection to the receiver or the power supply is interrupted. This ensures that the device status can be seen.
