Designed as a self-managing, plug-and-play solution, the system supports up to <strong>20 simultaneous channels<\/strong> while delivering consistent, high-quality audio in virtually any environment. It eliminates the complexity of traditional wireless setups by removing the need for frequency coordination, intermodulation calculations, and remote antenna cabling.<\/p>\n<p>At the heart of the system is the <strong>ATW-R1440 receiver<\/strong>, capable of handling up to four transmitters per channel for highly flexible operation. Receivers can remain docked in a half-rack chassis or be mounted remotely up to <strong>328 ft (100 m)<\/strong> away via Ethernet cable, allowing clean installations across large venues or distributed systems. Up to five chassis can be linked using the included RJ12 cable, enabling stable multichannel operation with as many as 20 channels in use simultaneously.<\/p>\n<p>The system offers selectable operating modes to suit different performance requirements. <strong>Standard mode<\/strong> supports up to 10 channels with minimal latency, while <strong>HD mode<\/strong> expands capacity to 20 channels for larger deployments. Setup, monitoring, and system control are streamlined through Audio-Technica\u2019s <strong>Wireless Manager software<\/strong>, which can manage multiple UHF, 2.4 GHz, and DECT wireless systems from a single interface.<\/p>\n<p>With <strong>AES128 encryption<\/strong> for secure transmission, paired transmitters ready to use out of the box, and all-day battery operation, the System 20 PRO delivers dependable performance for corporate AV, live events, education, houses of worship, and installed sound applications.<\/p>\n<hr>\n<h4>Key Features<\/h4>\n<p>\nDigital 24-bit \/ 48 kHz wireless operation for professional sound clarity and reliability<br \/>\nPlug-and-play operation in the 2.4 GHz band, free from TV interference<br \/>\nSelectable Standard mode (10 channels) or HD mode (20 channels)<br \/>\nRemote receiver mounting up to 328 ft (100 m) via Ethernet cable<br \/>\nLink up to five chassis for large multichannel systems<br \/>\nEach receiver channel can pair with up to four transmitters<br \/>\nSystem ID display shows RF level, battery status, and link condition<br \/>\nFlexible rack mounting with short and long rack ears and joining plate<br \/>\nCentralized control using Wireless Manager software<br \/>\nAuto-lock function prevents accidental operation changes<br \/>\nAES128 encryption ensures secure wireless communication<br \/>\nSyslog protocol compatibility for network monitoring<br \/>\nProject-based configuration and management via software<br \/>\nOLED displays on transmitters and receivers for clear status viewing<br \/>\nWater- and sweat-resistant cW-style connector on bodypack transmitters<br \/>\nCompatible with ATW-CHG3 series charging docks<br \/>\nMixed output support for installations with limited inputs\n<\/p>\n<hr>\n<h4>Specification<\/h4>\n<table class=\"spec-table\">\n<tbody>\n<tr>\n<td colspan=\"2\"><strong>Wireless System<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Operating Frequency<\/td>\n<td>2.4 GHz<\/td>\n<\/tr>\n<tr>\n<td>Audio Resolution<\/td>\n<td>24-bit \/ 48 kHz digital<\/td>\n<\/tr>\n<tr>\n<td>Operating Modes<\/td>\n<td>Standard Mode (10 channels), HD Mode (20 channels)<\/td>\n<\/tr>\n<tr>\n<td>Maximum Channel Count<\/td>\n<td>Up to 20 channels<\/td>\n<\/tr>\n<tr>\n<td>Encryption<\/td>\n<td>AES128<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\"><strong>Receiver<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Receiver Model<\/td>\n<td>ATW-R1440<\/td>\n<\/tr>\n<tr>\n<td>Transmitters per Channel<\/td>\n<td>Up to 4 transmitters<\/td>\n<\/tr>\n<tr>\n<td>Mounting Options<\/td>\n<td>Docked in chassis or remote mounted<\/td>\n<\/tr>\n<tr>\n<td>Remote Mount Distance<\/td>\n<td>Up to 328 ft (100 m) via Ethernet<\/td>\n<\/tr>\n<tr>\n<td>Chassis Linking<\/td>\n<td>Up to 5 chassis via RJ12 cable<\/td>\n<\/tr>\n<tr>\n<td>Status Display<\/td>\n<td>System ID display with RF level, battery level, and link status<\/td>\n<\/tr>\n<tr>\n<td>Display Type<\/td>\n<td>OLED<\/td>\n<\/tr>\n<tr>\n<td colspan=\"2\"><strong>Software &#038;
