The Audio-Technica ATW-1423 System 20 PRO Combo Wireless System includes the ATW-R1440 rack-mount receiver chassis, an ATW-RU14 receiver unit, four 2.4 GHz antennas, an AC adapter, rackmount or joining plate adaptors, an ATW-T1401 body-pack transmitter, and an ATW-1402 handheld transmitter.
The Audio-Technica ATW-1423 System 20 PRO Combo Wireless System provides high-quality digital 24-bit/48 kHz wireless operation for dependable performance in professional environments. This system operates in the 2.4 GHz range, ensuring it remains completely free from TV interference. It features a versatile configuration including the ATW-R1440 receiver chassis, the ATW-T1401 body-pack transmitter, and the ATW-T1402 handheld microphone transmitter.
Users can optimize the system for specific environments by switching between Standard and HD modes. Standard mode supports 10 channels to minimize latency, while HD mode allows for up to 20 channels to maximize the total channel count. The system supports the simultaneous use of up to five linked chassis, providing scalability for complex audio setups. For secure transmissions, the system utilizes AES128 encryption.
The ATW-R1440 receiver chassis provides flexible installation options for various venues. Receiver units can be docked directly in the chassis or mounted remotely up to 328 feet away via Ethernet cable. The chassis includes a System ID Display that provides real-time monitoring of important metrics:
The ATW-1423 system allows each receiver channel to pair with up to four transmitters, enabling users to switch between different transmitter configurations instantly. Both the handheld and body-pack transmitters feature OLED screens for clear readouts of key settings and alerts.
The Audio-Technica ATW-1423 is compatible with Wireless Manager software, allowing for centralized management of system settings and operations. This software enables users to configure, monitor, and save device settings as individual projects. The system also supports the Syslog protocol for advanced monitoring. To prevent accidental power-off or unintended channel changes, the hardware includes an auto-lock function. In scenarios where input channels are limited, the system supports mixed output to streamline audio routing.
