The C-YARK CY-7153D is a UHF wireless conference delegate unit with a built-in lithium battery, supplied in Bangladesh by DigiMark Solution as an authorized C-YARK Distributor.
Key features
Identical hardware to the chairman unit — the role is software — The CY-7153C and CY-7153D share the same capsule, battery, panel, and DSP. Identity is assigned from the host and can be switched live during a meeting. That means a spare unit covers either role, and a room can change its chair arrangement without moving hardware.
12 to 14 hours of speaking, 32 hours of standby — 2500 mAh 18650 cell, dual-battery optional. Enough for any realistic session, with the room able to be prepared a day ahead.
Charges while in use — Type-C charging with simultaneous operation, so a unit running low mid-session keeps working while plugged in.
φ14 mm super-cardioid gold-plated capsule with DSP — Same broadcast-grade capsule as the chairman unit, with per-unit equalisation and noise reduction before transmission.
Metal panel and detachable gooseneck — Built for rooms where units are set out and stored repeatedly rather than left permanently installed.
Where it is used
Every participant position other than the chair, in heritage rooms, rented halls and reconfigurable meeting spaces.
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.
