CMX 5G-157 Chairman & 5G-158 Delegate Units

The CMX 5G-157 Chairman Unit and 5G-158 Delegate Unit are professional 5G Wi-Fi conference terminals designed for boardrooms, council chambers, government offices, training centres, and corporate meeting rooms. Each unit features a 5-inch IPS display, a 420mm gooseneck microphone, and a capacitive cardioid capsule for focused speech pickup and clear communication.

Non-compressed digital audio transmission with a 48kHz sampling rate and an 80Hz–16kHz frequency response delivers natural conference speech. The units support check-in, discussion, voting, microphone status display, and multilingual operation in Chinese, English, French, and Russian. The 5G-157 chairman unit provides priority control and can open or close meeting check-in, while the 5G-158 delegate unit supports standard participant functions.

Wireless communication operates within the 5.1–5.8GHz band using 802.11a/n/ac Wave 2 technology. PC-based microphone management supports FIFO, APPLY, VOICE, and NORMAL modes. Additional features include camera auto-tracking compatibility, five-band EQ, feedback suppression, a 3.5mm earphone jack, USB expansion, and Type-C fast charging.

A rechargeable 5200mAh battery supports approximately 8–10 hours of continuous speaking, or up to 16 hours with two battery sets, making these units suitable for professional wireless conference installations in Bangladesh. An optional 5W Wi-Fi monitor speaker automatically mutes during microphone use to help prevent feedback in meetings.
