Compact, lightweight, and rugged design Features The DWT-B01N is designed to be extremely compact and lightweight, essential qualities for use by artists in fastmoving TV and outdoor productions. The DWT-B01N is a digital wireless transmitter for a UHF synthesized wireless microphone system to be used for broadcast or movie production purpose. This transmitter is suitable for Electronic News Gathering (ENG) and Electronic Field Production (EFP).
f POWER switch Turns the transmitter ON or OFF. Parts Identification g Battery compartment Accommodates two LR6 (size AA) alkaline batteries. For details on how to insert the batteries, see “Power Supply” on page 5. h SET button Adjusts displayed function settings and enters the value. Holding down the SET button while switching on the power turns the transmitter on without sending a signal.
For details, see “Locking the POWER switch (POWER SW LOCK)” on page 13. Power Supply G Cross Remote condition indication Indicates the signal transmission condition of the wireless remote control function (4 levels). : Good transmission : Somewhat good transmission : Somewhat poor transmission : Poor transmission : Unable to communicate with paired receiver When the wireless remote control function is off, this indication does not appear.
Setting the Transmission Channel The transmitter provides groups of interference-free channels. When using multiple microphones and transmitters at the same time (simultaneous multi-channel operations) within the same area, selecting the same group and using a channel within that group can prevent signal interference. To set the transmission channel on the transmitter, first you select the group and channel using the RF indicator and scanning functions on the receiver.
goes up, RF REMOTE turns on, and the remote control function becomes operative. Using the Cross Remote To use the Cross Remote with a previous pairing This transmitter is equipped with a wireless remote control function that can be used to set the parameters (low-cut filter, attenuation operation, power save mode, etc.) of the transmitter through the receiver or other devices. This function makes it easier to operate and manage the microphone system while in the field. This wireless control is 2.
When the RF REMOTE function is off, REMOTE cannot be selected. Using the Encrypted Transmission Function Note When the receiver does not support encryption key exchange through USB connection, select REMOTE. When you select USB: Connect the transmitter to the receiver with the USB cable (not supplied) and USB adapter cable (supplied). To prevent hacking of the signal, the transmitter scrambles the signal during transmission.
Note Using a USB Keyboard It is recommended that you change the password periodically. Connecting an optional USB keyboard to the transmitter allows you to perform menu operations and enter your name and password for the encrypted transmission function from the keyboard. A Micro USB connector is used on the transmitter. For this reason, use the supplied USB adapter cable.
Basic Menu Operations Setting Menus The functions and parameters of the settings menu are explained here. Underlined items are the factory setting. Function name Naming of transmitter (NAME) You can specify a transmitter name of up to 16 characters. The factory setting for the transmitter name is the model name and serial number. The transmitter name is sent to the receiver as metadata and is used by the receiver to distinguish between different transmitters.
microphone as you monitor the input level meter and press the + or – button repeatedly to select the appropriate attenuation level. The reference levels for the various settings are as follows: off the transmitter first. Then, while holding down the SET button, turn the power on. Then change the setting after the signal transmission has stopped. • Be sure to select the group/channel right after selecting the frequency band.
MODE1. We recommend using this mode under normal circumstances. MODE3: This audio codec mode prioritizes stable transmission performance. Additional signal processing is used to suppress noise and audio interruptions caused by unexpected interference, resulting in more reliable transmission. Setting the battery type (BATTERY TYPE) Set this item according to the type of batteries you use to obtain accurate battery power status indication.
Using wireless remote control, this function can be controlled from the receiver and other devices. Automatic dimming of the display (DIMMER MODE) For details on wireless remote control function, see “Using the Cross Remote” on page 7. The organic light-emitting diode display can be set to dim or turn off after a certain amount of time. Locking the POWER switch (POWER AUTO OFF: The display turns off after 30 seconds. The display goes on again when you press the SET, +, or – button.
Attaching With the Soft Case Attaching the Antenna Tubes The transmitter can be attached to the user with the supplied soft case. All operations are possible when the transmitter is attached with the soft case. The clip can be attached to the soft case at an angle of 0, 90, 180, or 270 degrees, allowing you to attach the transmitter in a variety of positions. Noise may occur if the antenna attachment areas come into contact with metallic objects.
