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 Specifications Overall System Operating Frequencies 2,402 to 2,480 MHz Dynamic Range 120 dB (A-weighted), typical Total Harmonic Distortion Maximum Simultaneous Use (recommended) Standard: 10 channels HD mode: 20 channels It depends on the region and environment.
