The TOA WS-432 Dual Channel Wireless Microphone Set offers a powerful solution for professional wireless audio systems. This set includes 2 wireless transmitters, 2 lavalier microphones, and a dual-channel receiver, all operating in the UHF frequency range of 694–806 MHz. The system supports up to 16 selectable channels, providing flexibility for seamless communication in various environments.

Each wireless transmitter is equipped with a back electret condenser microphone element with omnidirectional pickup, ensuring high-quality sound capture for clear, focused audio. The system’s audio frequency response spans 50Hz to 15kHz, delivering full-range sound with minimal distortion. With PLL synthesizer modulation and a maximum RF carrier power of 10mW, the system ensures stable signal transmission and reliable audio performance.

The transmitters run on a single AA alkaline battery (1.5V), providing approximately 10 hours of continuous use. Battery life is easily monitored with a battery status LED and 7-segment display, helping to prevent unexpected power loss during events or performances.

The wireless receiver features diversity reception, ensuring stable and interference-free audio by using two separate antenna inputs. It offers both balanced XLR and unbalanced ¼” jack outputs, making it compatible with various audio systems. The receiver also includes tone squelch (Tone SQ), carrier squelch (Carrier SQ), and noise squelch (Noise SQ) to reduce unwanted noise and improve signal clarity.

The set also includes an AC adapter, screw driver, and two lavalier microphones for hands-free operation.
