The Audio-Technica ATW-T1402 System 20 Pro Handheld Transmitter provides high-quality wireless audio transmission designed specifically for the System 20 PRO digital wireless system. This handheld transmitter delivers professional-grade performance and reliable signal stability for a variety of vocal applications.
The ATW-T1402 utilizes 24-bit/48 kHz audio processing to ensure high sound quality. This high-resolution digital output maintains the clarity and detail of the source audio, making it suitable for environments where vocal precision is required.
To maintain a consistent wireless connection, the transmitter features two antennas built directly into the housing. This internal antenna design helps optimize signal integrity during operation. The unit also includes a slide-to-mute switch, allowing the user to silence the audio output quickly and easily. An integrated OLED display provides clear visibility of essential transmitter information and settings.
The Audio-Technica ATW-T1402 is compatible with NiMH batteries, which support all-day use for extended sessions or events. This compatibility provides a reliable power solution for long-term operation. Every transmitter comes with an AT8456a Quiet-Flex stand clamp, facilitating secure mounting on standard microphone stands while maintaining flexibility for the user.
