Audio Technica System 20 PRO Dual Body‑Pack Wireless Microphone System (ATW‑1421)
Audio‑Technica System 20 PRO Dual Lavalier Wireless Microphone System (ATW‑1421/L)
- Dual lavalier digital wireless microphone system with body‑pack transmitters
- 24‑bit / 48 kHz audio for clear, natural speech reproduction
- Reliable 2.4 GHz operation free from TV and frequency interference
- Scalable system design with centralized software management
- AES128 encryption for secure wireless transmission
The System 20 PRO ATW‑1421/L is a professional dual lavalier wireless microphone system designed for presentations, conferencing, and installed AV environments. Operating in the globally available 2.4 GHz frequency range, it eliminates frequency coordination while delivering consistent, interference‑free digital audio.
The system includes an ATW‑R1440 four‑channel receiver, two ATW‑T1401 body‑pack transmitters, and two MT830cW lavalier microphones, providing a complete, ready‑to‑deploy solution for wearable microphone applications.
Wireless Performance & Audio Quality
- Digital 24‑bit / 48 kHz wireless operation
- Dynamic range: 120 dB (A‑weighted, typical)
- System frequency response: 20 Hz – 20 kHz (mic dependent)
- Total harmonic distortion: < 0.05%
Flexible Operating Modes
Users can switch between two operating modes to balance latency and channel capacity based on system requirements.
- Standard Mode: Up to 10 simultaneous channels with 2.8 ms latency
- HD Mode: Up to 20 simultaneous channels with 6.7 ms latency
Receiver & System Expansion
The ATW‑R1440 receiver can be docked directly into the chassis or mounted remotely up to 328 ft (100 m) away via Ethernet cable. Up to five receiver chassis can be linked and operated simultaneously for larger deployments.
- Each receiver channel can be paired with up to four transmitters
- Instant switching between different transmitter configurations
- Supports mixed output for systems with limited input channels
Body‑Pack Transmitters & Lavalier Microphones
- ATW‑T1401 body‑pack transmitters with cW‑style locking 4‑pin connectors
- Includes MT830cW lavalier microphones
- Secure connection for lavalier and headworn microphones
- OLED displays for battery, channel, and status information
System Management & Security
- Compatible with Audio‑Technica Wireless Manager software
- Configure, monitor, and save system settings as projects
- Auto‑lock function prevents unintended operation
- AES128 encryption for secure wireless audio
- Syslog protocol support for network monitoring
Power & Charging
- Rechargeable NiMH battery support
- Compatible with ATW‑CHG3 / ATW‑CHG3a and ATW‑CHG3N / ATW‑CHG3Na charging docks
Ideal Applications
- Corporate presentations and conferencing
- Education and lecture halls
- Government and institutional meeting spaces
- Professional installed AV systems
