Circuit Design, Inc. List of Products and Services

The transmitter WA-TX-03S and the receiver WA-RX-03S are wireless units for audio signals that comply with the ARIB standard RCR STD-15. The transmitter is equipped with a technical compliance mark, allowing for easy integration into devices to achieve wireless audio. It can be used on 30 channels from B11 to B61 thanks to the PLL synthesizer method. For the transmission of analog audio signals, it achieves low latency, a wide frequency response of 50Hz to 13kHz, and a dynamic range of 70dB through companding. Multiple receivers can receive signals without the need for pairing or other operations. It is ideal for applications in portable audio equipment. Transmitter: WA-TX-03S Receiver: WA-RX-03S
