How to Set Up Woojer Edge with an RF-Transmission system & Multi-Device Connectivity

Woojer Edge devices work by default with three audio connection types- 3.5mm analog audio, USB-C digital audio, and Bluetooth for wireless connection. While Bluetooth is a good solution for the personal user, when it comes to connecting multiple devices to the same source - latency and lack of compatible chipsets make the process much more difficult. If you connect several Bluetooth devices at the same location, you'll probably end up with radio interference and broken connections. 

A great alternative for multi-device connectivity would be using a balanced RF (Radio Frequency) transmission system. We've performed testing in our labs with great success using different platforms, and these guidelines are here to assist you with your connection and setup.

Most RF-Transmission kits come included with a central Transmission unit, 1-4 remote RF-Receivers, power supply, and more. There could be some differences between kits and companies, however, we recommend that you have the following items available for your setup. The amounts mentioned below are for a single Woojer and receiver setup:

1x RF-Transmission Unit

1x RF-Receiver Unit 

1x/2x AA Battery per Receiver (or other, depending on which batteries the RF-Receiver utilizes)

1x Woojer Edge

1x 3.5mm analog audio cable (comes included with the Woojer Edge)

1x Custom RF-Receiver unit holster (sold separately) 

1x 3.5mm Headset

Central RF-Transmitter Setup:

  1. The central transmission system - which will be referred to going forward as the transmitter - should come included with an antenna. If the antenna is not connected, make sure to connect it before usage and setup.
  2. Connect the transmitter to a compatible power supply. The transmitter should come with a dedicated power brick that matches its required voltage.
  3. Connect the transmitter to your sound console or audio mixer using a pair of 6.35mm cables or XLR-3 cables. Different transmitters will have different connection options available, but most if not all will have an XLR-3 connection available.
  4. Turn the transmitter on. If the transmitter has a screen display, it should display the currently used frequency channel. If the transmitter has no display, it should have a dial indicating which channels are available.
  5. If the transmitter is capable of either Mono or Stereo audio output, make sure that it is set to Stereo using either the dedicated dial or using the on-screen menu. 

Woojer and RF-Receiver Unit Setup:

  1. Turn the receiver unit on and turn its audio output level to maximum.
  2. Turn the Woojer on by pressing and holding the power button for 1-2 seconds. You should see the LED flashing blue, indicating that the device is awaiting a connection to a source. 
  3. Connect the receiver to the Woojer using a 3.5mm audio cable. The LED will turn from flashing blue to a solid blue.
  4. Make sure that the receiver's frequency (which is shown on its screen) is set to the same frequency as the central transmission system or the same channel. (Depending on your transmission system)
  5. Connect the 3.5mm headset to the Woojer's dedicated headphone output. 

Once all devices are connected, we recommend performing a test using a known audio file or cue that you use at your venue, to test that the response on all the Woojers is balanced to the same levels. 

Important: If you encounter distortion in the audio output from the headphones, please adjust the output sensitivity through the RF Transmitter or your audio console. As per testing, we've found -36 dB to be a good sensitivity output setting for the EK IEM G4, but your system may vary.
