Audio-Technica SYSTEM 20 PRO 2CH BOUNDARY 2.4 GHZ WLS

The ATW-1426 is a dual-channel professional digital wireless microphone system from the System 20 PRO line designed specifically for conference rooms, panel discussions, meeting rooms and similar fixed-install or portable setups. It uses two tabletop boundary-mic transmitters and a rack-mountable receiver that supports remote mounting, enabling flexible antenna placement and clean audio capture for two presenters or participants.

Key Features

• Digital 24-bit / 48 kHz wireless audio for high-quality sound delivery.

• Operates in the 2.4 GHz ISM band to avoid traditional UHF/VHF broadcast interference.

• Includes two tabletop boundary-microphone transmitters (cardioid pickup) that sit on desks or conference tables for hands-free speaker usage.

• Handled via a half-rack receiver chassis that contains a removable module; the receiver module may be mounted remotely (via Ethernet cable) up to ~100 m (~328 ft) away from the rack for optimized antenna placement.

• Triple-diversity reception (space, time, frequency) for reliable RF performance and minimal drop-outs.

• AES-128 encryption to secure the wireless audio link.

• Automatic frequency scanning and setup for minimal operator adjustment time.

• Two operational modes: Standard mode supports a lower-latency channel count; HD mode supports more simultaneous channels (important in multi-unit linking) depending on configuration.
