Unpack the unit and verify all supplied components are present. Transmitter (Tx) Receiver (Rx) Neckband assembly Type-C boom microphone Magnetic button Magnetic clip Split USB-C charging cable 3.5mm to 6.3mm output plug adaptor

The transmitter has an inbuilt microphone, which can be attached to clothing using either the magnetic button or clip for use facing upwards as a lavalier microphone.

THe transmitter can also be magnetically attached either side of the supplied neckband assembly for use as a neckband mic (with or without a boom microphone)

For more directed voice pickup, the USB-C boom microphone may be attached and used as a handheld wand microphone or on the neckband assembly as a headset microphone. The transmitter attaches to the neckband on either left or right side magnetically. When the boom mic is used, ensure the pin-hole on the USB-C connector is facing the user.

See below for assembly guidance.

Connections

Plug the receiver into a 6.3mm mic or line input on the mixer or other input device. Alternatively, removing the adaptor reveals a 3.5mm plug for connection to this size of socket. Ensure the output level is turned down to avoid loud noises when powering up.

Operation

Press and hold the transmitter power button for 3 seconds and it will power up. Press and hold the receiver power button for 3 seconds and it will also power up. Both units will pair if they are in close range. See below for pairing procedure.

Basic operation

Gradually turn up the output level on the mixer or other connected device and speak into the microphone until the voice is heard through the sound system, then increase to the required volume level.

The NL24 system operates on the license-free 2.4GHz carrier band and there are 4 channels selectable.

The receiver has 4 backlit numbers to show which channel is active. If the backlight is steady, the transmitter is paired with the receiver. If the backlight is flashing, it is in pairing mode with no transmitter linked.

The transmitter has a single LED that changes colour to indicate which channel is being used, or flashes when trying to pair.

A short press of the receiver's power button switches between channels.

To power transmitter and receiver down, press and hold the power button on each. It is advised to turn down the output level on connected equipment to avoid loud noises during power-off.

• No regular maintenance is required.
• To clean any of the components, use a dry cloth and avoid any ingress into the microphone parts.
