System 20 Digital Wireless System includes ATW-R1440 4-channel receiver and two ATW-T1401 body-pack transmitters.
Select microphones and/or cables with a cW-style locking 4-pin connector to complete the system.
Features
- Digital 24-bit/48 kHz wireless operation for ultimate sound quality and dependable performance
- Plug-and-play operation in the 2.4 GHz range – completely free from TV interference
- User can switch between Standard mode (10 channels) and HD mode (20 channels) to minimize latency or maximize channel count, respectively
- Receiver units can be docked in the chassis or mounted remotely (up to 328 feet away) via Ethernet cable for added versatility
- Up to five chassis can be linked and used simultaneously
- Each receiver channel can be paired with up to four transmitters, allowing users to instantly switch between different transmitter configurations
- Chassis’ System ID Display shows RF signal level, system ID, transmitter battery level, and system link status
- Each half-rack receiver chassis comes with a short and a long rack ear, and two long ears can be combined as a joining plate to secure two chassis in a full rack space
- Compatible with Audio-Technica’s Wireless Manager software for centralized management of system settings and operations
- Auto-lock function prevents unintended operations like turning off the power or displaying the channel select screen
- AES128 encryption for security
- Compatible with Syslog protocol
- Ability to configure, monitor, and save device settings as projects in Wireless Manager
- Transmitters and receivers include OLED screens for optimal readout of key settings and alerts
- Water- and sweat-resistant cW-style connector on body-pack transmitter provides secure connection to lavalier mics, headworn mics, and cables with cW-style locking 4-pin connector
- Charging terminals on body-pack and handheld transmitters work with ATW-CHG3/ATW-CHG3a and ATW-CHG3N/ATW-CHG3Na charging docks to recharge NiMH batteries
- Supports mixed output for situations with limited input channels
