Receiver and Tuner Unit

What are the basic elements that make up a wireless system?

There are several possibilities, but it can be stated that a transmitter, a receiver, and the radio waves that establish the connection form a basic combination. The system configuration is remarkably simple. Wireless systems transform audio signals into radio waves, transmit them, receive radio waves, and then convert them back into audio signals. The transmitting side is referred to as the "transmitter," while the receiving side is known as the "receiver" or "tuner."

There are several types of transmitters and receivers, but in any case they have internal transmit and receive capabilities.

​Radio Channel

To transmit a single audio signal, radio waves with a unique frequency are required in that space. The transmitter sends out this unique radio wave, and the receiver picks up this unique radio frequency. The term "unique" here is determined by the frequency of the radio wave. In essence, the transmitter and receiver must operate on the same frequency for wireless wave transmission and reception. For example, transmitting and receiving two signals simultaneously necessitates radio waves of two distinct frequencies. These multiple frequencies are identified to users as "channels."

Radio Channel Setting

The transmitter establishes the channel for transmission, and similarly, the receiver configures its receiving channel. The diagram provides an example of the setup method, which may vary depending on the model.

​Number of Selectable Channels and Simultaneously Used Channels

The transmitter and receiver can be configured to operate on one of multiple channels. The values listed in the table represent the frequencies of radio waves. The number of selectable channels varies for each model. Additionally, there is a grouping referred to as "BANK," and the number of channels that can be used simultaneously in the same space corresponds to the number of channels within one BANK.
(More specifically, a BANK is a set of channels designed to minimize issues such as intermodulation interference. However, the actual number of channels that can be used simultaneously may vary depending on external radio‑wave conditions and the placement of equipment.)
Please note that the numbers of selectable channels and simultaneously usable channels may differ.
