ACS-WLDCUWireless Chairman/Delegate Touch-Screen Unit

Description

Overview

The Macsys ACS-WLDCU is a professional wireless delegate/chairman touchscreen unit designed for flexible and secure conferencing. It supports dual-mode operation with wired (100M CAT5e/CAT6) and wireless (IEEE 802.11n, 2.4/5GHz) connections, ensuring seamless switching and stable communication. The 4.3-inch capacitive color touchscreen (800×480) provides a multilingual interface, while the built-in NFC reader (ISO/IEC14443 Type A) enables quick participant authentication and role assignment.

UsinT he unit delivers full digital, lossless audio with 48kHz sampling, 20Hz–20kHz response, >90dB SNR, <0.1% THD, and <5ms mic-to-speaker delay.

Integrated DSP includes a 16-band EQ, AGC, AFC feedback suppression, auto-mix, noise gate, and mic sensitivity adjustment (-12dB to +12dB), ensuring clear and natural sound in any environment.

The ACS-WLDCU supports multiple speaking modes: OPEN, VOICE, OVERRIDE (FIFO), APPLY (request-to-speak), optional Push-to-Talk, and ALL (full open). It allows 1, 2, 4, or 6 simultaneous microphones, expandable up to 32 units.

Software licenses enable advanced features such as voting (two-/three-/five-button), NFC sign-in, dual 64-channel simultaneous interpretation, and dual-user camera tracking.

Power is provided by a 6500mAh Li-ion battery, supporting ≥28 hours in power-saving mode and ≥14 hours with display active. Charging options include microphone base, PoE, or USB. Intelligent battery management shows status on the unit, web server, or PC software.

Reliability is enhanced with dual headphone jacks (independent volume, dual interpretation channels), hot plug-and-play with auto recovery, and loop/star network topologies for fault tolerance. Security is ensured with 128-bit AES encryption and WPA/WPA2 standards, preventing unauthorized access.

The compact unit supports pluggable gooseneck microphones of different lengths and analog-digital dual backup microphones. Interfaces include two RJ45 ports, dual headphone jacks, a stereo input, and an IC card slot.

The ACS-WLDCU is ideal for government, corporate, and enterprise applications. With secure connectivity, intelligent features, and superior audio performance, it delivers reliable and future-ready conference management.
