How the Digital Wireless System Works » How the Digital Wireless System Works Signal waveforms are used to represent sound, and the state of the sound is expressed according to the width or height of the waveform. Wireless microphones transduce the waveform of audio entering the microphone into an electrical signal and transmit that signal to a tuner over radio waves. In this event, it is an analog wireless system that processes the audio signal as it is in the waveform.
Advantages of the Digital Wireless System 1/2 Not only can the digital wireless system reduce the influence of noise, it can also maintain clear sound quality by means of digital processing. In addition to this, there are various advantages unique to the digital wireless system.
Advantages of the Digital Wireless System 2/2 » Reuse of the Same Channel Another advantage of the digital wireless system is that simultaneous use of multiple microphones on the same frequency in the same area can be realized more easily because of its immunity to radio interference and noise. In the case of analog systems, the distance between microphones should be at least 100 meters when using the same frequency channel in the same area to ensure 40 dB of D/U ratio.

Installation of the YW-4500 Wireless Antenna Important points for selecting the mounting position of diversity antennas are as follows: Point 1 Mount the two antennas within 20 – 30m (outdoor applications: 40 – 50m) visible range from the microphone’s area of intended use. Both antennas should be within visible range from any location where the microphones are to be used.
Antenna Distribution 1/2 • Using 1 - 3 channels Antennas can be distributed without using the WD-5800 Antenna Distributor.
Antenna Distribution 2/2 • Simultaneous use of 9 -16 channels to mixer audio to mixer audio to mixer audio to mixer audio • Simultaneous use of 17 - 32 channels Split antennas into two systems and construct a system of up to 32 channels.

Procedure for Reusing the Same Frequency 1/2 Wh e n u s i n g t ra n s m i tte rs i n nu m b e rs gre a te r t h a n t h e nu m b e r o f s i mu l ta n e o u s ly usable channels and in close proximity to each other, microphones operating on the same frequency can be used simultaneously by utilizing their digital characteristics. Note, however, that the same frequency cannot be used in the same room. 1. Make channel plans 1) Referring to the Frequency Table, select an arbitrary bank from A to F.
Procedure for Reusing the Same Frequency 2/2 2. Use "Code" (recommended) This function prevents interference between channels sharing the same frequency. By performing Code settings, receivers and transmitters can be paired, muting radio signals on the same frequency that may exist in the surrounding area. Code setting is effective when the encryption function is not set. Figure a. Even if the code is the same, if the power for both microphones is ON, radio interference will not occur.
Encryption Function Settings Exposure of important information can be prevented by pairing a receiver with a transmitter by TOA’s proprietary security IDs. » Engryption setting procedures 1) Enable receiver’s encryption function. Hold down the “SET” key for 2 seconds or more. Select ENCRYPTION from the menu Select “ON” MENU S E T E N C RY P T I O N > E N C RY P T I O N 3ON WT-D5800 AF PEAK ANTA ANT B A–1 RF A B μV 10 30 100 300 500 8 8 8 .
Interference Countermeasures Order of Actions (Action Flowchart) Change bank/channel numbers to those of idle channels. (See p. 10 - 13) Check reception indicators. No Any interference? Yes Use as is. Note Most interference can be avoided by operations above. If interference is still encountered, select channel having relatively less interference, then continue following operations. Perform antenna attenuator settings to limit service area. (See p. 18, “Antenna Attenuator”.
Antenna Attenuator » Antenna Attenuator Function This function decreases the antenna reception sensitivity so as to minimize reception of distant interference radio signals. Undesired Undesired •When to use this function Use this function when radio interference or signal interruption caused by the interference of other systems intermittently occurs.
FBS Setting » What is the feedback suppressor function? It is a function that the built-in feedback suppressor filter automatically works to suppress acoustic feedback when the feedback occurs.
EQ Setting (Recommended) » What is the microphone EQ built into the WT-D5800? This function optimizes audio characteristics for each model of handheld wireless microphone or any microphone connected to the belt-pack transmitter. Select the model number of the microphone to use, and perform settings in EQ setting mode. Hold down the “SET” key for 2 seconds or more.
Optimizing Sound Volume (1) Set the receiver’s volume control to the 2 o’clock position. For current TOA wireless receivers with the volume control located on the front panel, the 2 o’clock position (scale 7) is the volume control position that minimizes sound distortion until the maximum input sound pressure is applied to the microphone. From that position to the maximum volume position, a gain of approximately 10dB is made available as an allowance when turning up the volume.
