The C-YARK CY-7153C is a UHF wireless conference chairman unit with a built-in lithium battery, supplied in Bangladesh by DigiMark Solution as an Authorized C-YARK Distributor.
Key features
12 to 14 hours of continuous speaking, 32 hours standby — A 2500 mAh 18650 cell as standard, with a dual-battery option. Fourteen hours covers any realistic session including setup, and the 32-hour standby means a room prepared the night before is still ready.
Charges while in use, over Type-C — A unit running low mid-session can be plugged in and keep working. This is the specification that removes the main objection to wireless conference systems — that a microphone will die during a meeting.
φ14 mm super-cardioid gold-plated capsule — A 14 mm gold-plated electret condenser in a super-cardioid pattern. Larger capsule, tighter pattern — better pickup of the person speaking and better rejection of the person next to them.
Built-in DSP for equalisation and noise reduction — Processing happens in the unit rather than only at the host, so each microphone's signal is cleaned before transmission. In a wireless system, that matters more than in a wired one.
Detachable gooseneck with an aviation-lock connector — The gooseneck unscrews for transport and storage, and the aviation lock means it does not work loose in use. For a room whose units are stored between sessions, this is a practical difference.
Where it is used
The presiding position in heritage rooms, rented halls, and any room where cabling to the table is not possible.
Sizing a conference system
Three numbers decide the specification: seat count, room acoustics, and whether proceedings are recorded.
Seat count — one unit per seat plus one chairman unit. Count fixed positions, not typical attendance.
Room acoustics — a hard-surfaced room with glass and tile will echo regardless of microphone quality. Treatment does more for intelligibility per taka than any equipment upgrade.
Recording — if minutes may be challenged or transcribed, specify a controller with built-in recording and the higher-grade capsule. Retrofitting recording afterwards costs considerably more.

Complete Installation
What else you need for a working Kit
A single device is only part of a complete security or automation setup. Most projects need matching accessories, software and power components, chosen according to your site and requirements. You can start with a basic use case and upgrade later by adding the recommended supporting devices.
Price on request. Complete system pricing depends on the controller, chairman/delegate units, cabling, amplification, and seat count. WhatsApp: +880 1979-234342 for a quote.
On the CY-7153 series, the hardware is identical. The chairman or delegate role is assigned through the host system and can be changed during a meeting.
Generally, one unit per participant seat, plus one chairman unit. For example, 24 fixed seats require 24 units.
